Description

Technical Field

[0001] The invention relates to the technical field of flange processing, in particular to a valve flange processing drilling device. Background Art

[0002] Valve flange is an important component connecting pipes and valves. Its main function is to ensure the smooth transmission of fluids in the pipeline system and achieve a sealed connection through bolt fixing.

[0003] The valve flange is usually composed of two flat disc-shaped structures with a sealing gasket in the middle to prevent fluid leakage. The disc surface of the flat disc-shaped structure is usually provided with holes for connecting bolts. In order to ensure the accuracy of the valve flange connection, the processing of these holes is particularly important.

[0004] When drilling holes in valve flanges, drilling equipment is required. In related technologies, for example, Chinese patent CN207629236U discloses a valve flange drilling device. When the valve flange drilling device is in use, the valve flange to be drilled is placed from the feed plate, and the flange slides onto the conveyor belt. The conveyor belt then drives the flange to move under the drilling device, and then the drilling device is used to drill holes in the flange.

[0005] Although the above-mentioned valve flange drilling equipment can realize the drilling work on the valve flange, it is found in actual use that when the conveyor belt switches from a moving state to a stopped state, the flange will continue to slide forward due to inertia, resulting in misalignment between the position of the flange to be drilled and the drilling device, thereby affecting the accuracy of the flange drilling. Summary of the invention

[0006] Based on this, it is necessary to provide a valve flange processing drilling device to address the problem of low drilling accuracy in the current valve flange drilling process.

[0007] The above purpose is achieved through the following technical solutions: A valve flange processing and drilling device, the valve flange processing and drilling device comprising: A machine base, wherein a punching station is provided on the machine base; A movable plate is horizontally arranged on the base and forms a closed movable loop on the base, wherein the movable loop has at least two horizontal branches, and the two horizontal branches are arranged at intervals in the vertical direction; A clamp, disposed on the movable plate and configured to clamp the flange; A conveying plate, horizontally arranged on the machine base, capable of elastically sliding along the direction of the horizontal branch, and having corresponding first and second positions before and after sliding, wherein the conveying plate is configured to be able to convey the flange; A one-way blocking component is arranged on the machine base and divides the conveying plate into a positioning area and a waiting area along the conveying direction, and the one-way blocking component is configured to prevent the flange located in the positioning area from moving to the waiting area; when the movable plate moves along the horizontal branch located above, it can form a stopper cooperation with the conveying plate and drive the conveying plate to move from the first position to the second position, so that the positioning area is completely transformed into the waiting area, thereby allowing the flange located in the positioning area to freely fall onto the clamp and be clamped by the clamp; when the movable plate moves along the horizontal branch located below, it can drive the flange to move to the punching station through the clamp; A punching mechanism, configured to punch holes in the flange at the punching station; The moving mechanism is configured to drive the clamp to move to form the moving loop.

[0008] Furthermore, the one-way blocking assembly includes a bracket and two baffles, the bracket is fixedly arranged on the machine base; the two baffles are symmetrically arranged on the bracket, and one end of each baffle is unidirectionally elastically hinged on the bracket, and the other end is suspended; the one-way blocking assembly has a first state and a second state, when in the first state, the two baffles are located on the same straight line, and the straight line is perpendicular to the conveying direction; when in the second state, the two baffles together form an eight-shaped structure, and the small mouth of the eight-shaped structure faces the positioning area.

[0009] Further, the moving loop is in a square shape to have the two horizontal branches and the two vertical branches.

[0010] Furthermore, the moving mechanism includes an eccentric shaft, two triangular plates and two sliding frames. The eccentric shaft is inserted into the machine base and can rotate around its own axis; the two triangular plates are symmetrically sleeved on both ends of the eccentric shaft, one of the corners of the triangular plates corresponds to the eccentric shaft, and the shape of the triangular plates is a Lurox triangle; the sliding frame is square in shape, and is movably arranged on the machine base and sleeved on the outside of the triangular plates; the moving plate is fixedly arranged on the two sliding frames at the same time.

[0011] Furthermore, the corners corresponding to the triangular plate and the eccentric shaft are chamfered.

[0012] Furthermore, the moving mechanism also includes a driving component, and the driving component is configured to provide a driving force for the rotation of the eccentric shaft.

[0013] Furthermore, after the clamp switches from the horizontal branch located above to the vertical branch, the moving speed of the clamp in the vertical direction is greater than the moving speed of the flange, so that the clamp and the flange gradually move away from each other, and the clamp simultaneously clamps the flange during this process.

[0014] Furthermore, when the movable plate moves along the horizontal branch located above, the top plate surface of the movable plate is lower than the top plate surface of the conveying plate.

[0015] Furthermore, the valve flange processing and drilling device also includes a supporting portion, and the supporting portion is configured to support the movable plate in a vertical direction when the punching mechanism punches holes in the flange.

[0016] Furthermore, the clamp is an electric three-jaw chuck.

[0017] The beneficial effects of the present invention are: The valve flange processing and drilling device disclosed by the present invention is first used to arrange a plurality of flanges in a row and place them on a conveying plate, and then push the flange at the rear to move forward, and the flange at the rear synchronously drives all the previous flanges to move forward, so that the flange at the front passes the one-way blocking component and moves to the positioning area; then the moving plate is driven to move along the moving loop by the moving mechanism, and when the moving plate moves along the horizontal branch located above, it can form a stopper cooperation with the conveying plate, and drive the conveying plate to move from the first position to the second position, so that the positioning area is completely transformed into a waiting area, and then the flange located in the positioning area can freely fall onto the fixture and be clamped by the fixture, this process effectively avoids the possible misalignment problem between the fixture and the flange, and lays a foundation for precise positioning for subsequent drilling operations, thereby significantly avoiding adverse effects on the accuracy of flange drilling; when the moving plate moves along the horizontal branch located below, the moving plate drives the flange to move to the punching station through the fixture, and then the flange is punched by the punching mechanism, thereby improving the punching accuracy.

[0018] Furthermore, by setting the chamfered arc angles of the corners corresponding to the triangle plate and the eccentric shaft, during use, when the other corners of the triangle plate push the sliding frame to move, the corners corresponding to the triangle plate and the eccentric shaft are set tangent to the sliding frame throughout the entire process due to the chamfered arc angle, thereby avoiding resistance to the movement of the sliding frame.

[0019] Furthermore, after the clamp switches from the horizontal branch located above to the vertical branch, the moving speed of the clamp in the vertical direction is greater than the moving speed of the flange, so that the clamp and the flange gradually move away from each other. During this process, the clamp clamps the flange at the same time, thereby avoiding the influence of static friction on the clamping and positioning of the flange. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figures 1 to 4As shown, the valve flange processing and drilling device provided by the embodiment of the present invention is used to punch holes in the flange 9, and is configured to include a machine base 1, a movable plate 2, a fixture 3, a conveying plate 4, a one-way blocking component 5, a punching mechanism 6 and a movable mechanism 7, and a punching station is arranged on the machine base 1; the movable plate 2 is horizontally arranged on the machine base 1, and a closed movable circuit is formed on the machine base 1, and the movable circuit has at least two horizontal branches, and the two horizontal branches are arranged at intervals in the vertical direction; the fixture 3 is arranged on the movable plate 2, and is configured to clamp the flange 9; the conveying plate 4 is horizontally arranged on the machine base 1, and can slide elastically in the direction of the horizontal branch, and has corresponding first and second positions before and after sliding, and the conveying plate 4 is configured to convey the flange 9; the one-way blocking component 5 is arranged on the machine base 1, and the conveying plate 4 ... can convey the flange 9; the one-way blocking component 5 is arranged on the machine base 1, and the conveying plate 4 can slide elastically in the direction of the horizontal branch, and has corresponding first and second positions before and after sliding, and the conveying plate 4 can convey the flange 9; the one-way blocking component 5 is arranged on the machine base 1, and the conveying plate 4 can slide elastically in the direction of the horizontal branch, and has corresponding first and second positions before and after sliding, and the conveying plate 4 can convey the flange 9; the one-way blocking component 5 is arranged on the machine base 1, and the conveying plate 4 can slide elastically in the The movable plate 2 is on the seat 1, and the conveying plate 4 is divided into a positioning area and a waiting area along the conveying direction, and the one-way blocking component 5 is configured to prevent the flange 9 located in the positioning area from moving to the waiting area; when the movable plate 2 moves along the horizontal branch located at the top, it can form a stopper with the conveying plate 4, and drive the conveying plate 4 to move from the first position to the second position, so that the positioning area is completely converted into the waiting area, and then the flange 9 located in the positioning area can fall freely onto the clamp 3 and be clamped by the clamp 3; when the movable plate 2 moves along the horizontal branch located at the bottom, it can drive the flange 9 to move to the punching station through the clamp 3; the punching mechanism 6 is configured to punch holes in the flange 9 at the punching station; the movable mechanism 7 is configured to drive the clamp 3 to move to form a moving loop.

[0026] Specifically in this embodiment, the punching station is located directly below the punching mechanism 6; in order to facilitate the description of the installation position of the movable plate 2 and to clarify the direction of the horizontal branch, it is set that the base 1 has a mounting platform 101, such as Figure 1 As shown, the mounting platform 101 is configured as a rectangular plate structure and is horizontally arranged during installation; the plate surface of the movable plate 2 is parallel to the plate surface of the mounting platform 101 and is suspended above the mounting platform 101, and the horizontal branch extends along the length direction of the mounting platform 101, so that the movable plate 2 can move along the length direction of the mounting platform 101.

[0027] like Figure 1 As shown, the conveying plate 4 is located above the moving plate 2 and is flush with the horizontal branch located above, so that when the moving plate 2 moves along the horizontal branch located above, it can form a stopper with the moving plate 2; to facilitate the installation of the conveying plate 4, it is configured that the base 1 also has a first installation box 102, and the first installation box 102 is vertically arranged on the right side of the installation platform 101, and to ensure the rationality of the structural layout, the left side wall of the first installation box 102 and the plate surface of the installation platform 101 are vertically arranged, and the conveying plate 4 is slidably inserted into the left side wall of the first installation box 102 during installation.

[0028] To ensure that the flange 9 can be smoothly moved from the conveying plate 4 to the moving plate 2, as Figure 1 As shown, the conveying plate 4 and the movable plate 2 can both be set as rectangular plate structures, and the length direction of the movable plate 2 is parallel to the width direction of the mounting platform 101, and the length direction of the conveying plate 4 is parallel to the length direction of the movable plate 2, so that when the movable plate 2 and the conveying plate 4 are stopped, the right side wall of the movable plate 2 and the left side wall of the conveying plate 4 are in surface contact, so that the flange 9 can be smoothly moved from the conveying plate 4 to the movable plate 2.

[0029] In order to facilitate the elastic sliding of the conveying plate 4, at least one compression spring is inserted in the first installation box 102. The compression spring is horizontally arranged and extends along the length direction of the installation platform 101, and is connected between the conveying plate 4 and the first installation box 102, so that when the movable plate 2 pushes the conveying plate 4, on the one hand, the compression spring can be compressed and stored, and on the other hand, the reverse thrust of the compression spring on the conveying plate 4 is only along the length direction of the installation platform 101, avoiding the generation of force components in other directions, resulting in unnecessary wear between the conveying plate 4 and the first installation box 102, and affecting their service life; when the movable plate 2 and the conveying plate 4 are out of coordination, the compression spring is released and drives the conveying plate 4 to reset.

[0030] During use, Figure 1 Taking the angle shown as an example, first, multiple flanges 9 are arranged in a row and placed on the conveying plate 4, and the extension direction of the row composed of multiple flanges 9 is parallel to the width direction of the conveying plate 4, and then the rightmost flange 9 is pushed to move to the left, and the rightmost flange 9 simultaneously drives all the previous flanges 9 to move to the left, so that the leftmost flange 9 passes the one-way blocking component 5 and moves to the positioning area.

[0031] Then, the moving plate 2 is driven to move along the moving loop through the moving mechanism 7. When the moving plate 2 moves from left to right along the horizontal branch located above, it can form a stopper cooperation with the conveying plate 4, and drive the conveying plate 4 to move from the first position to the second position, and simultaneously compress the compression spring, so that the positioning area is completely transformed into a waiting area, so that the flange 9 located in the positioning area can freely fall onto the clamp 3 and be clamped by the clamp 3. This process effectively avoids the possible misalignment problem between the clamp 3 and the flange 9, and lays a foundation for precise positioning for subsequent drilling operations.

[0032] When the moving plate 2 and the conveying plate 4 are out of engagement, the conveying plate 4 can automatically return to its original position under the push of the compression spring.

[0033] When the movable plate 2 moves from right to left along the horizontal branch located below, the movable plate 2 drives the flange 9 to move to the punching station through the clamp 3, and then the flange 9 is punched by the punching mechanism 6, thereby improving the punching accuracy.

[0034] It can be understood that, in order to provide driving force for the movement of the flange 9, a first driving cylinder is also inserted inside the first installation box 102. The first driving cylinder is horizontally arranged, and the output shaft extends along the width direction of the conveying plate 4 and is located at the same height as the flange 9. The first driving cylinder and the flange 9 are arranged correspondingly, so that when in use, the first driving cylinder can be started, and the output shaft of the first driving cylinder extends out and pushes on the flange 9 located on the far right, thereby synchronously driving all the previous flanges 9 to move to the left through the flange 9 on the far right.

[0035] It can be understood that the first driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0036] In some embodiments, the one-way blocking component 5 is configured to include a bracket 501 and two baffles 502, and the bracket 501 is fixedly set on the base 1; the two baffles 502 are symmetrically arranged on the bracket 501, and one end of each is unidirectionally elastically hinged on the bracket 501, and the other end is suspended; the one-way blocking component 5 has a first state and a second state. When in the first state, the two baffles 502 are located on the same straight line, and the straight line is perpendicular to the conveying direction; when in the second state, the two baffles 502 together form an eight-shaped structure, and the small mouth of the eight-shaped structure faces the positioning area.

[0037] Specifically in this embodiment, in order to facilitate the support of the baffle 502 and avoid affecting the one-way passage of the flange 9, as shown in FIG. Figure 3 As shown, the bracket 501 is configured to be composed of two separate upper and lower parts, and the upper and lower parts have exactly the same structure and are symmetrically arranged on the upper and lower sides of the conveying plate 4; Figure 1 As shown, taking a part of it as an example, the part is composed of a first strip 5011 and a second strip 5012, wherein the first strip 5011 is horizontally arranged and extends along the width direction of the conveying plate 4, and the right end of the first strip 5011 is vertically arranged on the left side wall of the first installation box 102 during installation, and the left end is suspended, the second strip 5012 is horizontally arranged and extends along the length direction of the conveying plate 4, the second strip 5012 is vertically arranged with the first strip 5011 during installation, and is located above the first strip 5011 and the conveying plate 4 at the same time, the front end of the second strip 5012 is arranged at the top of the left end of the first strip 5011, and the rear end is suspended, and the conveying plate 4 part on the left side of the second strip 5012 is a positioning area, and the conveying plate 4 part on the right side of the second strip 5012 is a waiting area.

[0038] like Figure 3 As shown, the upper end of the baffle bar 502 located on the upper side is hinged to the suspended end of the second bar 5012 located on the upper side, and the lower end is suspended; the lower end of the baffle bar 502 located on the lower side is hinged to the suspended end of the second bar 5012 located on the lower side, and the upper end is suspended; at this time, the one-way blocking assembly 5 is in the first state, and the two baffle bars 502 are located on the same straight line, and the straight line is perpendicular to the conveying direction.

[0039] In order to facilitate the elastic hinge of the blocking bar 502, a torsion spring is provided at the hinge between each blocking bar 502 and the second bar 5012. Under the action of the torsion spring, the blocking bar 502 has a tendency to remain in the same straight line with the second bar 5012.

[0040] To facilitate the unidirectional swinging of the baffle bar 502 , a block is provided on the suspended end of each second bar 5012 and near the hinge between the second bar 5012 and the baffle bar 502 . Under the block of the block, the baffle bar 502 can only swing in one direction.

[0041] Initially, the one-way blocking assembly 5 is in the first state, and the two blocking bars 502 are located on the same straight line.

[0042] During use, the first drive cylinder is started, and the output shaft of the first drive cylinder is extended. Figure 3 As shown, the output shaft of the first driving cylinder pushes against the flange 9 located on the far right, and then the flange 9 on the far right synchronously drives all the previous flanges 9 to move to the left.

[0043] When the leftmost flange 9 moves to contact with the two baffles 502, as the output shaft of the first drive cylinder continues to extend, the leftmost flange 9 synchronously pushes the two baffles 502, so that the one-way blocking assembly 5 is in the second state. Under the push of the leftmost flange 9, the two baffles 502 both swing to the left and form an eight-shaped structure. The torsion spring accumulates force synchronously, and the more the leftmost flange 9 moves to the left, the larger the opening of the small end of the eight-shaped structure. When the opening of the small end of the eight-shaped structure increases to be larger than the diameter of the flange 9, as the leftmost flange 9 continues to move to the left, the leftmost flange 9 passes over the two baffles 502 and moves completely to the positioning area.

[0044] When the leftmost flange 9 is completely moved to the positioning area, the first drive cylinder is closed, and the two baffles 502 swing to the right under the action of the torsion spring, pressing the second flange 9 from the left to the right and all the flanges 9 on the right to move to the right to achieve reset.

[0045] In other embodiments, in order to improve the punching efficiency and avoid invalid paths, the shape of the moving loop is set to be a square, so as to have two horizontal branches and two vertical branches.

[0046] In a further embodiment, the moving mechanism 7 is configured to include an eccentric shaft 701, two triangular plates 702 and two sliding frames 703. The eccentric shaft 701 is inserted into the machine base 1 and can rotate around its own axis; the two triangular plates 702 are symmetrically sleeved on both ends of the eccentric shaft 701, one of the corners of the triangular plates 702 corresponds to the eccentric shaft 701, and the shape of the triangular plates 702 is a Lurox triangle; the sliding frame 703 is square in shape, and is movably arranged on the machine base 1 and sleeved on the outer side of the triangular plate 702; the moving plate 2 is fixedly arranged on the two sliding frames 703 at the same time.

[0047] Specifically in this embodiment, in order to facilitate the installation of the mobile mechanism 7, the base 1 is configured to further include a second installation box 103, such as Figure 1 As shown, the second installation box 103 is vertically arranged on the top of the installation platform 101, and in order to ensure the rationality of the structural layout, the right side wall of the second installation box 103 and the left side wall of the first installation box 102 are arranged in parallel; Figure 1 and Figure 4 As shown, the eccentric shaft 701 is horizontally arranged during installation and extends in a width direction parallel to the installation platform 101, and the front and rear ends of the eccentric shaft 701 respectively pass through the front and rear side walls of the second installation box 103; the triangular plate 702 is located on the outside of the second installation box 103 during installation, and the plate surface of the triangular plate 702 and the axis of the eccentric shaft 701 are vertically arranged, so that the plane where the triangular plate 702 moves can be parallel to the moving direction of the movable plate 2; the sliding frame 703 is located on the outside of the second installation box 103 during installation, and the sliding frame 703 and the front side wall of the second installation box 103 are parallelly arranged, so that the sliding frame 703 and the triangular plate 702 can move in the same plane.

[0048] To facilitate the connection of the sliding frame 703, as Figure 1 As shown, two connecting rods 201 are vertically arranged on the left side wall of the movable plate 2. The two connecting rods 201 are respectively located at the front and rear ends of the movable plate 2, and the ends of the two connecting rods 201 away from the movable plate 2 are respectively arranged on two sliding frames 703.

[0049] In order to enable the sliding frame 703 to be movably arranged on the base 1, as shown in FIG. Figure 1As shown, two slide rails 104 are provided on the front and rear side walls of the second installation box 103, and the slide rails 104 extend along the length direction of the installation platform 101, and the two slide rails 104 on the same side are arranged at intervals in the vertical direction, and the left and right ends are aligned; a limit frame 105 is slidably inserted between the two slide rails 104 on the same side, and the limit frame 105 can only slide along the extension direction of the slide rail 104 under the guidance of the slide rail 104, and the limit frame 105 is set to a rectangular frame structure, and the length direction of the limit frame 105 extends along the vertical direction. The sliding frame 703 is slidably inserted in the limit frame 105 during installation, and under the restriction of the limit frame 105, the sliding frame 703 can only slide relative to the limit frame 105 in the vertical direction, and under the joint restriction of the slide rail 104 and the limit frame 105, the sliding frame 703 can move along a square track.

[0050] To prevent the sliding frame 703 from falling, Figure 1 As shown, a limit bar 1051 is provided on the left long frame bar of the limit frame 105, and two limit bars 1051 are provided on the right long frame bar of the limit frame 105, and the limit bars 1051 extend along the length direction of the limit frame 105, and the two limit bars 1051 on the right side are arranged at intervals, and the three limit bars 1051 have overlapping parts in the length direction of the limit frame 105, and the limit bars 1051 extend inwardly along the width direction of the limit frame 105 to cover the outer edge of the sliding frame 703, thereby blocking the sliding frame 703.

[0051] During use, the eccentric shaft 701 is driven to rotate around its own axis, and the eccentric shaft 701 synchronously drives the two triangular plates 702 to rotate around the axis of the eccentric shaft 701, the triangular plates 702 drive the sliding frame 703 to move along the square trajectory, and the sliding frame 703 synchronously drives the moving plate 2 to move along the square moving loop.

[0052] In a further embodiment, since the shape of the triangle plate 702 is set to be a Lurox triangle, when the triangle plate 702 pushes the sliding frame 703, the three corners of the triangle plate 702 are in contact with the inner frame surface of the sliding frame 703, and only the two corners of the triangle plate 702 away from the eccentric shaft 701 have a pushing effect on the sliding frame 703, and the corner of the triangle plate 702 close to the eccentric shaft 701 has an obstructive effect on the sliding frame 703, thereby reducing the transmission efficiency. To solve this problem, the corners corresponding to the triangle plate 702 and the eccentric shaft 701 are set to be chamfered arc angles.

[0053] Specifically in this embodiment, during use, when the two corners of the triangle plate 702 away from the eccentric shaft 701 push the sliding frame 703 to move, the corners corresponding to the triangle plate 702 and the eccentric shaft 701 are rounded, so that the corners are set tangent to the sliding frame 703 throughout the entire process, thereby avoiding resistance to the movement of the sliding frame 703 and further improving the transmission efficiency.

[0054] In other embodiments, in order to enable the sliding frame 703 to be movably disposed on the base 1 , the sliding frame 703 may also be configured to be magnetically connected to the second installation box 103 so as to be adsorbed on the side wall surface of the second installation box 103 by magnetic force.

[0055] In other embodiments, the moving mechanism 7 is configured to further include a driving component (not shown), and the driving component is configured to provide a driving force for the eccentric shaft 701 to rotate.

[0056] Specifically in this embodiment, the drive assembly is inserted into the second installation box 103 and is configured to include a first drive motor, a first bevel gear and a second bevel gear, wherein the first bevel gear is fixedly sleeved on the motor shaft of the first drive motor, and the second bevel gear is fixedly sleeved on the eccentric shaft 701.

[0057] During use, the first drive motor is started, and the first drive motor drives the eccentric shaft 701 to rotate around its own axis through the direct meshing of the first bevel gear and the second bevel gear.

[0058] In other embodiments, during the process of the clamp 3 clamping the flange 9, since the flange 9 is a disc-shaped structure, the clamp 3 will clamp the flange 9 in a centered manner; and during the centering process, the clamp 3 and the flange 9 will switch from a static state to a relative moving state, and then switch from a relative moving state to a static state. Since there is friction between the clamp 3 and the flange 9, the friction will interfere with the position of the flange 9, thereby causing inaccurate positioning, thereby affecting the punching accuracy. To solve this problem, it is set that after the clamp 3 switches from the horizontal branch located above to the vertical branch, the moving speed of the clamp 3 in the vertical direction is greater than the moving speed of the flange 9, so that the clamp 3 and the flange 9 gradually move away from each other, and the clamp 3 clamps the flange 9 at the same time during this process.

[0059] Specifically in this embodiment, when the clamp 3 is switched from the horizontal branch located at the top to the vertical branch, the speed of the moving plate 2 can be increased by increasing the speed of the first drive motor and the speed of the eccentric shaft 701, so that the moving speed of the clamp 3 in the vertical direction is greater than the moving speed of the flange 9, thereby allowing the clamp 3 and the flange 9 to gradually move away from each other. Due to the separation of the clamp 3 and the flange 9, there is no contact between the flange 9 and the clamp 3, and no friction is generated, thereby preventing the friction from interfering with the position of the flange 9.

[0060] In other embodiments, due to processing errors and installation errors, the top plate surface of the movable plate 2 is unlikely to be aligned with the top plate surface of the conveying plate 4, and may even be slightly higher than the top plate surface of the conveying plate 4, resulting in the flange 9 being unable to move smoothly from the conveying plate 4 to the movable plate 2, thereby affecting the subsequent clamping and punching process. To solve this problem, it is configured that when the movable plate 2 moves along the horizontal branch located above, the top plate surface of the movable plate 2 is lower than the top plate surface of the conveying plate 4.

[0061] Specifically in this embodiment, since the top plate surface of the movable plate 2 is lower than the top plate surface of the conveying plate 4, even if the processing error and the installation error are taken into account, the top plate surface of the movable plate 2 is still lower than the top plate surface of the conveying plate 4, so that the flange 9 can be smoothly moved from the conveying plate 4 to the movable plate 2.

[0062] In other embodiments, since the movable plate 2 is suspended, when the flange 9 is punched by the punching mechanism 6, on the one hand, the movable plate 2 will easily vibrate, thereby affecting the punching accuracy of the flange 9 at that time; on the other hand, the movable plate 2 will gradually accumulate downward bending under multiple punchings of the punching mechanism 6, and thus gradually bend, thereby affecting the subsequent punching accuracy of the flange 9. To solve this problem, the valve flange processing and drilling device is configured to also include a support part 8, and the support part 8 is configured to support the movable plate 2 in the vertical direction when the punching mechanism 6 punches the flange 9.

[0063] Specifically in this embodiment, Figure 1 As shown, the number of support parts 8 can be two, and they are symmetrically arranged on the top of the mounting platform 101. The support part 8 can be set to a ladder-shaped structure, and the whole extends in the horizontal direction and is supported at the bottom of the movable plate 2 so as to be able to support the movable plate 2 in the vertical direction.

[0064] It is understandable that the support portion 8 may also be configured to be any other shape capable of supporting the movable plate 2, such as a columnar, conical or irregular shape.

[0065] In other embodiments, the clamp 3 can be configured as an electric three-jaw chuck.

[0066] In other embodiments, the clamp 3 may also be configured as a pneumatic / hydraulic three-jaw chuck.

[0067] In other embodiments, the clamp 3 can also be configured as an electric / pneumatic / hydraulic four-jaw chuck.

[0068] In other embodiments, the punching mechanism 6 is configured to include a sliding seat 601, a second driving cylinder, a third driving motor 602 and a drill bit 603. Figure 1As shown, the sliding seat 601 is installed on the right side wall of the second installation box 103 and can slide in the vertical direction; the second driving cylinder is arranged at the top of the second installation box 103, and the output shaft of the second driving cylinder is arranged in the vertical direction and downward, and is fixedly connected to the top of the sliding seat 601, so as to drive the sliding seat 601 to slide in the vertical direction; the third driving motor 602 is installed on the top of the sliding seat 601, and the motor shaft of the third driving motor 602 is arranged in the vertical direction and downward; the drill bit 603 is fixed to the end of the motor shaft of the third driving motor 602.

[0069] It can be understood that the second driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0070] During use, when the movable plate 2 drives the flange 9 to move to the punching station through the clamp 3, the second drive cylinder is started, the output shaft of the second drive cylinder is extended, and the third drive motor 602 and the drill bit 603 are driven to move downward synchronously through the sliding seat 601; when the drill bit 603 contacts the flange 9, the third drive motor 602 is started, and the third drive motor 602 drives the drill bit 603 to rotate to punch the flange 9.

[0071] In other embodiments, since there are generally multiple holes to be drilled on the flange 9, in order to improve the drilling efficiency, the clamp 3 can be configured to be rotatable around a vertical line so as to be able to switch between different positions to be drilled on the flange 9 and the corresponding drilling mechanism 6.

[0072] Specifically in this embodiment, the valve flange processing drilling device is configured to also include a second drive motor, and the second drive motor is inserted in the movable plate 2, and the motor shaft of the second drive motor is fixedly inserted at the bottom of the clamp 3 to drive the clamp 3 to rotate around a vertical line, so as to be able to switch the different positions to be punched on the flange 9 and the corresponding punching mechanism 6.

[0073] In other embodiments, during the resetting process of the conveying plate 4, since it is achieved under the push of the compression spring, the conveying plate 4 will be reset faster, which may cause relative displacement between the conveying plate 4 and the flange 9, thereby affecting the subsequent positioning accuracy of the flange 9. To solve this problem, it is configured that at least one one-way damping cylinder is also inserted in the first installation box 102, the one-way damping cylinder is horizontally arranged, and the whole extends along the length direction of the installation platform 101, the output shaft of the one-way damping cylinder is connected to the conveying plate 4, and the damping direction is set to prevent the output shaft from extending out of the cylinder body, so that when the moving plate 2 pushes the conveying plate 4 to move from the first position to the second position, the one-way damping cylinder does not play a damping role, thereby avoiding adding unnecessary load; when the conveying plate 4 is reset, the conveying plate 4 can be slowly reset under the damping action of the one-way damping cylinder, so that the conveying plate 4 and the flange 9 can move synchronously.

[0074] In other embodiments, the flanges 9 are pushed against each other to drive the leftmost flange 9 to pass the one-way blocking assembly 5 and move to the positioning area, and the flanges 9 are approximately in point contact, resulting in that during the movement of the flanges 9, the flanges 9 may not move all along the conveying direction of the conveying plate 4, resulting in misalignment between the flanges 9, thereby causing the leftmost flange 9 to be unable to move to the positioning area, or even if it can move to the positioning area, there may be position deviations, affecting the subsequent clamping of the clamp 3. To solve this problem, two limit rods are provided at the top of the vertical section of the mounting hole of the first mounting box 102, and the limit rods extend along the width direction of the conveying plate 4. The two limit rods are arranged at intervals along the length direction of the conveying plate 4 to limit the flange 9 between the two limit rods, so that the flange 9 can only move along the conveying direction of the conveying plate 4.

[0075] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
