Description

Technical Field

[0001] The invention relates to the technical field of screw rod processing and milling, in particular to a screw rod processing and milling device. Background Art

[0002] The screw processing rotary milling equipment is a machine tool specially used for processing screws and other parts with spiral shapes. The equipment combines the characteristics of milling and rotation, and can efficiently and accurately process complex spiral shapes such as threads and grooves.

[0003] In the process of rotary milling of a long screw, both ends of the screw need to be fixed first, and then the middle section of the screw is processed by a milling cutter. However, due to the long distance of the screw, the middle section of the screw is difficult to maintain its balance only by the clamping at both ends, so the middle section will shake during the processing; and when the milling cutter processes the shaking screw, it is easy to cause mutual damage between the two, which is not conducive to the rotary milling of the screw; and the processing of the screw is completed at one time, and the rotation of the milling cutter will not be interrupted during this process. Long-term processing will cause the temperature of the milling cutter to be too high when processing the screw in the second half, thereby causing damage to the milling cutter.

[0004] In order to solve the above problems, there are many solutions in the prior art, such as the ultra-long screw processing milling machine with patent number CN104259594B, which cooperates with the feeding mechanism and the traction mechanism. The feeding mechanism provides rotational power, and the traction mechanism converts part of the rotational power into linear forward motion, thereby realizing the rotation and linear forward motion of the workpiece. In theory, it can realize the processing of ultra-long screws of any length. Although this method realizes the processing of long screws, when the screw is too long, the middle section lacks constraint. At this time, it is difficult to achieve stability in the processing of the milling cutter and the screw, which in turn affects the milling efficiency during screw processing.

[0005] Based on this, in order to solve the problem that when processing a long screw, the middle section of the screw cannot be clamped, so the milling cutter collides with the shaking screw in the second half, and the temperature of the milling cutter increases with the processing time, resulting in low milling efficiency, the present invention designs a screw processing milling equipment. Summary of the invention

[0006] The present invention provides a screw processing and milling equipment. In order to solve the problem that when processing a long screw, the middle section of the screw cannot be clamped, so that the milling cutter collides with the shaking screw in the second half, and the temperature of the milling cutter increases with the processing time, resulting in low milling efficiency, the solution of segmented conversion of the clamping point is adopted. The position of the clamping point is changed according to the position of the milling, thereby ensuring that the middle section of the long screw is also in a clamped state, thereby improving the efficiency of the screw milling.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The present invention provides a screw processing and milling equipment, comprising a workbench, a three-jaw chuck, a fixing ring, a main motor, an auxiliary driving member, a milling cutter, an electric push rod, a driving mechanism, an adjusting mechanism, a top block and a clamping plate, wherein the three-jaw chuck is installed on the left side of the top of the workbench, the fixing ring is installed on the right side of the workbench, the main motor and the auxiliary driving member are both installed on the workbench, the milling cutter is installed on the output end of the auxiliary driving member, the electric push rod is installed on the workbench, the output end of the electric push rod is connected to the auxiliary driving member, the driving mechanism is installed on the workbench, the three-jaw chuck clamps a screw, the driving mechanism is located above the workbench and at the center of the screw, and the adjusting mechanism Located at the driving mechanism, the clamping plate is installed at the screw, the top block is installed at the adjusting mechanism, the electric push rod drives the top block to move in the same direction as the milling cutter, the top block drives the adjusting mechanism through the driving mechanism, the adjusting mechanism drives the clamping plate to clamp the screw, and the clamping plate at the rear of the middle part is driven to loosen through the driving mechanism, while the clamping plate at the front of the middle part is clamped, thereby achieving the clamping of the long screw. During the clamping process, the clamping plate is at a certain inclination angle with the horizontal plane, which can block the debris splashed by the milling cutter, thereby preventing the residues from the milling cutter from affecting the subsequent milling, and also preventing the splashing of water used for cooling, thereby ensuring that the water cooling area is always located in the middle to the milling cutter milling area.

[0009] Preferably, the clamp is divided into a left clamp and a right clamp, the left clamp is located in the middle of the screw near the three-jaw chuck, and the right clamp is located in the middle of the screw on the side of the fixed ring. The left clamp changes from a guiding role to a clamping role, and then moves the fixed point from the three-jaw chuck on the left to the clamping position of the middle left clamp. At this time, the suspended length of the screw is shortened and the stability of the screw is enhanced; while the right clamp initially has a clamping role, which moves the clamping point of the right end of the entire screw to the left, thereby shortening the suspended section of the screw in the initial state from the three-jaw chuck to the fixed ring to the three-jaw chuck to the right clamp. At this time, the right clamp has a clamping and fixing role.

[0010] Preferably, the driving mechanism includes a plate a, a plate b, a placement table, an adsorption chamber, a magnetic block, a magnet a, a magnet b, and a reset spring. The plate a and the plate b are both installed on the top block, and the screw is located above the plate a. The placement table is installed in the middle of the workbench, and the plate a and the plate b are distributed on both sides of the placement table. The adsorption chamber is opened in the placement table, and the magnetic block is located in the adsorption chamber. The magnet a is slidably installed on the right side of the plate a, and the magnet b is slidably installed on the left side of the plate b. The reset spring is installed at the ends of the magnet a and the magnet b, where the magnetic force of the magnetic block can be set to be affected by the magnet a and the magnet b, that is, when the two are adsorbed at the same time, the magnetic force of the magnetic block is the weakest, and the attraction is the weakest, so that one of them can leave easily, and if only one is adsorbed, the magnetic force is relatively strong.

[0011] Preferably, the adjustment mechanism includes an adjustment cavity, a slider, and a tension spring. The adjustment cavity is opened on the plate a and the plate b. The slider is located in the adjustment cavity and slides. The bottom ends of the two sliders are respectively in contact with the magnet a and the magnet b. The tension spring is installed between the plate a and the left clamp, and is synchronously installed between the plate b and the right clamp. The specific clamping can adopt the lever principle or the clamping principle of the torsion spring. No specific details are given here. It is only necessary that the left clamp and the right clamp ends can clamp the screw when they are lowered. The figure shows the lever principle.

[0012] Preferably, water outlets are installed on the opposite surfaces of the left clamp and the right clamp, and the water outlets are initially facing the milling cutter. Through the water outlets in different directions, the position of the water flow reaching the milling cutter and the screw can be changed, thereby cooling the processed screw in the initial state. After the milling cutter passes over the placement table, the milling cutter and the screw to be milled are pre-treated and cooled through the water outlet.

[0013] Preferably, push blocks are installed at the ends of the plate a and the plate b, and the top block is in contact with the push block; the push block is divided into a fixed part and a movable part, and the fixed part and the movable part are connected by a torsion spring. The push block and the top block can control the milling cutter to pass over the plate a without causing interference.

[0014] Preferably, the angle between the left clamp and the plate a is 0-60°, and rubber pads are installed on the bottom surfaces of the left clamp and the right clamp. The rubber pads are used to protect the processed threads of the screw and also reduce the hard contact between the screw and the left clamp and the right clamp when the screw rotates.

[0015] Preferably, when the milling cutter is on the left side of the placement table, the non-free end of the milling cutter does not exceed the edge of the left clamp, and when the milling cutter is on the right side of the placement table, the non-free end of the milling cutter does not exceed the edge of the right clamp, thereby ensuring that the milling cutter can be completely located between the left clamp and the plate a, thereby preventing iron filings from scattering.

[0016] Preferably, the contact surfaces of the magnet a, magnet b and slider are all wedge-shaped surfaces, and the angle of the wedge-shaped surface is 45 to 90°, so that the longitudinal movement distance of the slider is greater than the lateral movement distance, thereby increasing the deflection angle of the left clamp and the right clamp.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention proposes a screw processing rotary milling equipment. In the process of the lateral movement of the milling cutter, the clamping plate clamps the middle rear of the screw under the action of the adjusting mechanism. When the milling cutter moves to the middle rear of the screw, the driving mechanism drives the clamping plate at the middle rear to loosen, while the clamping plate at the middle front is clamped, thereby achieving the clamping of the long screw. During the clamping process, the clamping plate is at a certain inclination angle with the horizontal plane, which can block the splashing of debris from the milling cutter, thereby preventing the residue from the rotary milling of the milling cutter from affecting the subsequent rotary milling. At the same time, it can also block the splashing of water used for cooling, ensuring that the water cooling area is always located in the rotary milling area from the middle to the milling cutter, thereby improving the rotary milling effect during screw processing.

[0019] 2. The present invention proposes a screw processing rotary milling equipment. When it moves to the placement table, the plate a is stationary. At this time, the magnet a in the plate a is attracted by the magnetic block in the adsorption chamber, and the magnet a moves to the right. At this time, the milling cutter continues to move to the right over the placement table, and the top block will drive the plate b to move to the right. At this time, the magnet b is moved away from the slider by the reset spring, and the slider is reset to reset the right clamp, so that the clamping effect of the right clamp disappears, and the right clamp becomes a guide, thereby realizing the conversion of the clamping point, thereby improving the clamping stability during the rotary milling process, and thereby improving the rotary milling efficiency.

[0020] 3. The present invention proposes a screw processing rotary milling equipment, in which a screw is placed between the left clamp and the plate a. When the left clamp clamps the screw, there is a certain angle between the left clamp and the plate a. At this time, some debris can be scattered outward along the surface of the left clamp, while the debris in the front will splash to the front and rear sides along the gap between the right clamp and the plate b, thereby avoiding affecting the rotary milling of the milling cutter and improving the efficiency of rotary milling.

DETAILED DESCRIPTION

[0032] In order to better understand the above solution, the above technical solution is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1 As shown, Figure 1 The viewing angle is a positive viewing angle to distinguish left and right. A screw processing rotary milling device provided by the present invention includes a workbench 1, a three-jaw chuck 2, a fixing ring 3, a main motor 4, an auxiliary driving member 5, a milling cutter 6, an electric push rod 7, a driving mechanism 8, an adjusting mechanism 9, a top block 10 and a clamping plate 11. The three-jaw chuck 2 is installed on the left side of the top of the workbench 1. The position of the three-jaw chuck 2 can be moved horizontally to the left and right, so as to adapt to screw workpieces 12 of different lengths, and it is also convenient for the placement of the screw workpiece 12. After the long screw is placed, it is fixed by the three-jaw chuck 2. The fixing ring 3 is installed on the right side of the workbench 1. The fixing ring 3 is used to fix the other end of the long screw, and the fixing method is not unique and is a prior art, which can be a clamping claw type or a pipe sleeve type.

[0034] The main motor 4 and the auxiliary driving member 5 are both installed on the workbench 1, the main motor 4 is used to drive the screw workpiece 12 to rotate, the milling cutter 6 is installed on the output end of the auxiliary driving member 5, the auxiliary driving member 5 is used to drive the milling cutter 6 to rotate, the electric push rod 7 is installed on the workbench 1, the electric push rod 7 can push the milling cutter 6 to move left and right along the direction of the screw workpiece 12, thereby realizing rotary milling, the output end of the electric push rod 7 is connected to the auxiliary driving member 5, the electric push rod 7 pushes the auxiliary driving member 5 to move laterally, the driving mechanism 8 is installed on the workbench 1, the three-jaw chuck 2 clamps the screw workpiece 12, the driving mechanism 8 is located above the workbench 1 and at the center of the screw workpiece 12, the adjusting mechanism 9 is located at the driving mechanism 8, the clamping plate 11 is installed at the screw workpiece 12, the top block 10 is installed at the adjusting mechanism 9, the electric push rod 7 drives the top block 10 to move in the same direction as the milling cutter 6, the top block 10 drives the adjusting mechanism 9 through the driving mechanism 8, and the adjusting mechanism 9 drives the clamping plate 11 to clamp the screw workpiece 12.

[0035] When the screw needs to be processed by rotary milling, the worker clamps the screw workpiece 12 through the three-jaw chuck 2 and the fixing ring 3, and then drives the main motor 4 to rotate the screw workpiece 12. During the rotation of the screw workpiece 12, the electric push rod 7 is driven to make the auxiliary driving part 5 and the milling cutter 6 move laterally, thereby rotary milling the surface of the screw workpiece 12. During the lateral movement of the milling cutter 6, the clamping plate 11 clamps the middle and rear part of the screw workpiece 12 under the action of the adjustment mechanism 9, and when the milling cutter 6 moves to the screw workpiece 12, the clamping plate 11 is clamped by the adjustment mechanism 9. When it is at the rear of the middle part, the driving mechanism 8 is used to drive the clamp 11 at the rear of the middle part to loosen, while the clamp 11 at the front of the middle part is clamped, thereby achieving the clamping of the long screw. During the clamping process, the clamp 11 is at a certain inclination angle with the horizontal plane, which can block the debris splashed by the milling cutter 6, thereby preventing the residues milled by the milling cutter 6 from affecting the subsequent milling, and at the same time, it can also block the splashing of water used for cooling, ensuring that the water cooling area is always located in the milling area from the middle to the milling cutter 6, thereby improving the milling effect during screw processing.

[0036] like Figure 2As shown, the clamping plate 11 is divided into a left clamp 111 and a right clamp 112. The left clamp 111 is located in the middle of the screw workpiece 12 close to the three-jaw chuck 2, and the right clamp 112 is located in the middle of the screw workpiece 12 on the side of the fixing ring 3. The left clamp 111 is used to guide the milling cutter 6 to gradually spin mill the screw workpiece 12. In the initial process, the left clamp 111 does not play a clamping role, but a guiding role. After being guided to the middle of the screw workpiece 12, under the influence of the driving mechanism 8, the left clamp 111 changes from a guiding role to a clamping role, and then moves the fixed point from the left three-jaw chuck 2 to the clamping position of the middle left clamp 111. At this time, the suspended length of the screw workpiece 12 is shortened, and the stability of the screw workpiece 12 is enhanced; while the right clamp 112 initially has a clamping role, which moves the right end clamping point of the entire screw workpiece 12 to the left, so that the screw workpiece 12 in the initial state The suspended section is shortened from the three-jaw chuck 2 to the fixing ring 3 to the three-jaw chuck 2 to the right clamp 112, at which time the right clamp 112 has a clamping and fixing function; when the milling cutter 6 is milled to the right side of the middle section of the screw workpiece 12, it will drive the right clamp 112 to move up under the action of the driving mechanism 8 and the adjusting mechanism 9. At this time, the right clamp 112 is loosened, and the right clamp 112 will follow the milling cutter 6 to move to the right, forming a guiding and protective effect; it should be noted that the clamping force of the left clamp 111 and the right clamp 112 here does not need to be very large, as long as it can prevent the screw workpiece 12 from shaking, and based on the fact that the left and right ends of the screw workpiece 12 are fixedly clamped, even if the middle section is just lifted, it can offset the thrust of the milling cutter 6 during the milling process, so even if it is just a plane press, it can improve the overall clamping effect, so the clamping effect of the left clamp 111 and the right clamp 112 is not described in detail here.

[0037] like Figure 3 As shown, the driving mechanism 8 includes a plate a81, a plate b82, a placement table 83, an adsorption chamber 84, a magnetic block 85, a magnet a86, a magnet b87, and a reset spring 88. The plate a81 and the plate b82 are both installed at the top block 10, and the screw workpiece 12 is located above the plate a81. The placement table 83 is installed in the middle position of the workbench 1. The plate a81 and the plate b82 are distributed on both sides of the placement table 83. The adsorption chamber 84 is opened in the placement table 83. The magnetic block 85 is located in the adsorption chamber 84. The magnet a86 is slidably installed on the right side of the plate a81, and the magnet b87 is slidably installed on the left side of the plate b82. The reset spring 88 is installed at the ends of the magnet a86 and the magnet b87.

[0038] The flat plate a81 is located on the left side of the milling cutter 6. Initially, the screw workpiece 12 can be in contact with the flat plate a81, that is, the flat plate a81 can provide an upward support force for the screw workpiece 12, but the friction between the flat plate a81 and the screw workpiece 12 should also be reduced. Therefore, this can be achieved through materials, surface smoothness or adding lubrication. The flat plate a81 can play a supporting role for the screw workpiece 12. Before the milling cutter 6 moves horizontally to the middle part, the flat plate a81 can play a supporting role and also guide the milling cutter 6 to spin mill the screw workpiece 12, avoiding the spin milling process of the milling cutter 6. The position in the middle is longitudinally offset; when it moves to the placement table 83, the flat plate a81 is stationary. At this time, the magnet a86 in the flat plate a81 is attracted by the magnetic block 85 in the adsorption chamber 84, and the magnet a86 moves to the right, pulling the reset spring 88 while driving the adjustment mechanism 9 to work. At this time, the milling cutter 6 continues to move to the right over the placement table 83, and the top block 10 will drive the flat plate b82 to move to the right. At this time, the flat plate b82 is away from the placement table 83, and the magnet b87 in the flat plate b82 moves to the right synchronously, and then under the action of the reset spring 88, the magnet b87 is gradually reset.

[0039] like Figure 4 As shown, the adjustment mechanism 9 includes an adjustment cavity 91, a slider 92, and a tension spring 93. The adjustment cavity 91 is opened on the plate a81 and the plate b82. The slider 92 is located in the adjustment cavity 91 and slides. The bottom ends of the two sliders 92 are in contact with the magnet a86 and the magnet b87 respectively. The tension spring 93 is installed between the plate a81 and the left clamp 111, and is synchronously installed between the plate b82 and the right clamp 112. The contact surfaces of the magnet a86, the magnet b87, and the slider 92 are all wedge-shaped surfaces, and the angle of the wedge surface is 45 to 90°.

[0040] In the process of magnet a86 and magnet b87 moving successively, they will push the corresponding slider 92 to move. In the initial state, magnet b87 is in the state of squeezing slider 92. At this time, slider 92 will support the right clamp 112, so that the right clamp 112 is in an inclined state. After the milling cutter 6 passes over the placement table 83, the top block 10 drives the plate b82 to move to the right. At this time, magnet b87 is moved away from slider 92 by the reset spring 88. The slider 92 is reset, so that the right clamp 112 is reset, and then the clamping effect of the right clamp 112 disappears. The right clamp 112 becomes a guide, thereby realizing the conversion of the clamping point, thereby improving the clamping stability during the rotary milling process, and thereby improving the rotary milling efficiency.

[0041] like Figure 5As shown, water outlets 13 are installed on the opposite surfaces of the left clamp 111 and the right clamp 112. The water outlet 13 at the left clamp 111 initially faces the milling cutter 6. In the initial state, the water outlet 13 at the left clamp 111 faces the milling cutter 6, thereby cooling the surface of the milling cutter 6 and removing debris during the milling process. As the milling time of the milling cutter 6 gradually increases, the temperature of the milling cutter 6 gradually increases. Therefore, when reaching the right clamp 112, the right clamp 112 faces the working direction of the milling cutter 6, thereby improving the cooling efficiency. At the same time, the left clamp 111 cools the surface of the workpiece while clamping the workpiece, thereby avoiding the problem of affecting the milling effect due to long-term processing of the workpiece or excessive temperature of the milling cutter 6.

[0042] like Figure 2 , 6 As shown, push blocks 14 are installed at the ends of the flat plate a81 and the flat plate b82, and the top block 10 is in contact with the push block 14; the push block 14 is divided into a fixed part 141 and a movable part 142, and the fixed part 141 and the movable part 142 are connected by a torsion spring 143. In the initial state, the fixed part 141 and the movable part 142 are acted upon by the torsion spring 143. At this time, when the top block 10 drives the movable part 142, the fixed part 141 will move synchronously, and at the same time, it will drive the flat plate a81 or the flat plate b82 to move; when the flat plate a81 reaches the placement table 83, the fixed part 141 is pressed against the placement table 83, so when the top block 10 continues to move to the right, the movable part 142 will be folded, and then it will pass over the movable part 142, and then move to the movable part 142 at the flat plate b82, driving the flat plate b82 to move, thereby improving the convenience of replacing the clamping point.

[0043] like Figure 7-9 As shown, the angle between the left clamp 111 and the plate a81 is 0-60°, and rubber pads 15 are installed on the bottom surfaces of the left clamp 111 and the right clamp 112. A screw workpiece 12 is placed between the left clamp 111 and the plate a81, and the milling cutter 6 is processed on the right side of the left clamp 111. Therefore, the products of the milling of the milling cutter 6 may splash above the left clamp 111. When the left clamp 111 clamps the screw workpiece 12, in order to prevent the debris from returning to the milling position again, a certain angle is required between the left clamp 111 and the plate a81. At this time, some debris can be scattered outward along the surface of the left clamp 111, and the debris in the front will splash to the front and rear sides along the gap between the right clamp 112 and the plate b82, thereby avoiding affecting the milling of the milling cutter 6. The right clamp 112 is preferably formed into a wing shape when placed horizontally, which can guide the flow direction of iron chips and water. The rubber pad 15 is used to protect the processed threads of the screw workpiece 12 , and also reduces the hard contact between the screw workpiece 12 and the left clamp 111 and the right clamp 112 when the screw workpiece 12 rotates.

[0044] When the milling cutter 6 is on the left side of the placement table 83, the non-free end of the milling cutter 6 does not exceed the edge of the left clamp 111, and when the milling cutter 6 is on the right side of the placement table 83, the non-free end of the milling cutter 6 does not exceed the edge of the right clamp 112, thereby ensuring that the milling cutter 6 can be completely located between the left clamp 111 and the flat plate a81, and thus during the initial guiding process, debris will not splash everywhere, and after passing over the placement table 83, the water flow can be guided to cool the milling cutter 6 as a whole, thereby improving the efficiency of rotary milling.

[0045] When it is necessary to process a long screw by rotary milling, the worker clamps the workpiece above the workbench 1 through the three-jaw chuck 2 and the fixing ring 3. At this time, the main motor 4 drives the screw workpiece 12 to rotate, and the auxiliary drive member 5 drives the milling cutter 6 to rotate. After both are rotated, the electric push rod 7 is started to process the screw workpiece 12 horizontally. At this time, the plate a81 is located on the left side of the milling cutter 6, and the top block 10 moves synchronously horizontally under the action of the electric push rod 7. The top block 10 drives the push block 14 on the plate a81 to move, thereby guiding the moving direction of the milling cutter 6. When the milling cutter 6 moves to the placement table 83, the magnetic block 85 in the adsorption chamber 84 adsorbs the magnet a86, and the magnet a86 drives the slider 92 in the adjustment chamber 91 to move upward, thereby driving the left clamp 111 to tilt, and synchronously clamping the left end of the milling cutter 6; at this time, the fixed part 141 on the push block 14 is blocked by the placement table 83, and then The movable part 142 is folded by the torsion spring 143 and the fixed part 141, and the top block 10 passes over the movable part 142 and reaches the push block 14 at the plate b82, and then drives the plate b82 to move, and the magnet b87 in the plate b82 is separated from the adsorption of the magnetic block 85, and is reset under the action of the reset spring 88, and then drives the right clamp 112 to reset under the action of the lifting spring, and then the right clamp 112 changes from an inclined state to a horizontal state, thereby releasing the clamping of the right part of the screw workpiece 12, and at the same time plays a protective and guiding role; at the same time, the water outlet 13 is used to cool the milling cutter 6 and the screw workpiece 12; after the milling cutter 6 reaches the right end, the fixed part 141 on the plate b82 is also blocked by the placement table 83, and then the movable part 142 is folded under the action of the torsion spring 143, and at this time the milling cutter 6 reaches the rightmost position, and at this time the milling cutter 6, the plate a81 and the plate b82 can be adjusted to reset.

[0046] The basic principles and beneficial effects of the present invention are shown and described above. At the same time, the present invention is not limited to the above embodiments. Without departing from the effects and scope of the present invention, the present invention may have various changes and improvements. These changes and improvements all fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
