Description

Technical Field

[0001] The present invention belongs to the technical field of punching equipment, and particularly relates to a numerical control punching machine for processing camera brackets. Background Art

[0002] A numerical control punching machine is an advanced form of a punching machine, and its operation and monitoring are completely completed through a numerical control unit. Compared with an ordinary punching machine, a numerical control punching machine has the characteristics of high machining accuracy, large machining width, multi-coordinate linkage machining ability, and high automation degree. It is suitable for the processing of various metal sheet parts, and can automatically complete the processing of a variety of complex hole patterns and shallow drawing forming, greatly improving the production efficiency and machining accuracy.

[0003] When processing a camera bracket, due to the special structure of the camera bracket, it has two parts: a main body and a sub-body. Both the main body and the sub-body are provided with through holes along the central axis, and the central axes of the main body and the sub-body form a 60-degree angle. Moreover, the main body and the sub-body are not in the same vertical plane, and both the top and bottom ends of the sub-body protrude from the side wall of the main body by a certain distance. When using an existing punching machine for deburring the inner wall of the hole, because of the special contour of the camera bracket, the existing clamping fixture can only directly contact the vertical side wall of the main body. After clamping, the sub-body of the camera bracket forms a 60-degree angle with the vertical direction. In this state of a large angle, the punching action will generate a large horizontal component force, resulting in unstable clamping or even detachment of the camera bracket. In view of this, a numerical control punching machine for processing camera brackets is provided. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a numerical control punching machine for processing camera brackets.

[0005] The technical solution adopted to solve the above technical problem is as follows:

[0006] A numerical control punching machine for processing camera brackets includes a bed base, and further includes: a bed frame fixed on the top of the bed base, the bed frame includes a connecting plate, and equidistantly arranged guide rails are installed on the top surface of the connecting plate;

[0007] A positioning frame slidably embedded on the bed frame, the positioning frame includes a bottom plate, a first support block and a second support block are installed on the top of the bottom plate, a middle plate is installed between the first support block and the second support block, and a clamping jaw is arranged on the side of the middle plate away from the bottom plate;

[0008] A processing component located above the bed base, the processing component includes an impact drill, and a three-degree-of-freedom linear module for driving the impact drill to move up and down and back and forth, and the three-degree-of-freedom linear module can drive the impact drill to swing reciprocally along the extending direction of the guide rail;

[0009] A camera bracket fixed on a positioning frame. The camera bracket includes a main body and a secondary body with a central axis included angle of sixty degrees. The main body is provided with a central hole along the central axis direction, and the secondary body is provided with a side hole along the central axis direction. The positioning frame can make the central axes of the main body and the secondary body form an angle of sixty degrees with the horizontal line.

[0010] Further, the first support block has a first contact surface, and the second support block has a second contact surface. The first contact surface and the second contact surface are perpendicular to each other. The main body has a first lower end surface and a second lower end surface that are perpendicular to each other. The first lower end surface is parallel to and in direct contact with the first contact surface, and the second lower end surface is parallel to and in direct contact with the second contact surface.

[0011] Through the above technical solution, the second support block is higher than the first support block. When the camera bracket is placed between the second support block and the first support block, the camera bracket will be tilted with one end high and the other end low. In this way, the angle differences between the central hole and the side hole and the vertical line can both be thirty degrees. Because of the smaller angle difference with the vertical line, it can ensure that when being impacted by the hole-opening impact of a percussion drill, the horizontal component force is smaller, and the damage to the percussion drill is smaller. At the same time, by designing the first contact surface and the second contact surface at the contact position, and further increasing the contact area, the stability of the support is increased.

[0012] Further, the middle plate is provided with a sliding opening corresponding to the clamping jaws. The clamping jaws can slide horizontally in the sliding opening. The middle plate is arranged parallel to the second lower end surface. The clamping jaws are provided with baffles above the sliding opening, and the baffles are in sliding contact with the top surface of the middle plate.

[0013] Through the above technical solution, the design of the sliding opening makes the clamping jaws be horizontally limited by the middle plate, ensuring the horizontal precision of the sliding of the clamping jaws. And a baffle that slides with the clamping jaws is arranged at the top of the sliding opening. While not affecting the displacement of the clamping jaws, it prevents debris above from entering the sliding opening, ensuring smooth sliding. And it can play a limiting role on the clamping jaws through direct contact with the top surface of the middle plate. When the clamping jaws open and squeeze the inner wall of the main body, the reaction force will cause the clamping jaws to tilt towards the center of the central hole. At this time, the baffle can transfer the acting force to the position of the middle plate, ensuring that the angle of the clamping jaws will not be twisted, ensuring firm clamping, and improving the structural stability of the clamping jaws during long-term use.

[0014] Further, the central hole is in the shape of a circle at the top and a rectangle at the bottom. There are four clamping jaws. The side of the clamping jaws facing the inner wall of the central hole is in a flat shape, and the clamping jaws are provided with liners at the flat part.

[0015] Through the above technical solution, due to the shape of the central hole, the clamping jaws will contact the flat surface. Therefore, by designing the contact surface of the clamping jaws as a flat surface, the effective contact area can be increased. At the same time, liners are installed at the positions where the clamping jaws contact the camera bracket. The liners can adopt a wear-resistant hard structure to improve the service life, or a flexible structure that can be elastically deformed to avoid wearing the inner wall of the main body.

[0016] Further, an actuating member is installed at one end of the middle plate facing the bottom plate. The actuating member is assembled and connected with the clamping jaws, and the actuating member can drive two clamping jaws located on the same middle plate to approach each other.

[0017] Through the above technical solution, the actuating member can adopt two inverted hydraulic cylinders to respectively drive the sliding actions of the two clamping jaws on the middle plate, and make them act synchronously through the hydraulic control device. The clamping force generated by this drive is greater. It is also possible to use a lead screw equipped with two such lead screw nuts. The thread directions of the two lead screw nuts are opposite, and the two clamping jaws are respectively fixedly connected to one lead screw nut. When the lead screw rotates, the two clamping jaws can be driven to move in opposite directions, and the speed of this drive is faster.

[0018] Further, a receiving groove is formed between adjacent guide rails. A sliding groove is opened in the upper part of the vertical side wall of the guide rail. A slag outlet is provided below the middle hole of the bottom plate and the middle plate. A sliding pin is installed at the bottom end of the bottom plate, and the sliding pin is slidably installed in the sliding groove.

[0019] Through the above technical solution, the receiving groove has an upward opening and gaps are also left at both front and rear ends. In this way, the generated debris can directly enter the receiving groove. Moreover, the bottom plate is slidably installed on the top surface of the guide rail, and the sliding pin is slidably installed in the sliding groove, so that the entire positioning frame is installed above the guide rail in a suspended manner, preventing the debris accumulated below the receiving groove from affecting the installation and disassembly of the positioning frame. At the same time, when cleaning the debris between the guide rails, it is not necessary to disassemble the positioning frame on the guide rail, making it more convenient to use.

[0020] Further, side plates are provided at the ends of the second supporting block. There are two side plates. The tops of the two side plates extend upward beyond the top surface height of the second supporting block, and the vertical side walls on the opposite sides of the two side plates are in sliding contact with the vertical outer wall of the main body.

[0021] Through the above technical solution, the side plates play a limiting role. When placing the camera bracket above the positioning frame, in order to ensure that the clamping jaws can be inserted into the middle hole, it is necessary to position the camera bracket in the left-right direction. At this time, the gap between the two side plates is equal to the width of the main body, which can play a role of sliding limit when placing the camera bracket. At the same time, when processing the side holes of the sub-body, the impact will generate a downward pressure. Since the central axis of the sub-body is located outside the entity of the positioning frame, it will cause a downward twisting trend of the camera bracket, resulting in unstable support of the camera bracket. At this time, the side plates will serve as a horizontal support structure to prevent the camera bracket from twisting.

[0022] Further, a bolt hole is opened at the end of the bottom plate. The bolt hole is perpendicular to the guide rail. A bolt is screwed and installed in the bolt hole, and the bottom surface of the bolt is in direct contact with the top surface of the guide rail.

[0023] Through the above technical solution, after the positioning frame is installed, the positioning frame can be directly fixed on the guide rail by tightening the bolts. With the clamping connection between the sliding pin and the sliding groove, it is ensured that the positioning frame will not shift horizontally.

[0024] Furthermore, a protective cover is provided on the periphery of the bed base around the bed frame. A protective door is provided on the vertical side wall of the protective cover, and the protective door is provided with an observation window.

[0025] Through the above technical solution, to ensure the safety of processing, a protective cover can be installed. To ensure controllable operation, the protective door and the observation window facilitate internal debugging, rapid discovery of dangers, and timely replacement of parts.

[0026] The beneficial effects of the present invention are as follows:

[0027] (1) Through the design of the positioning frame in the present invention, the camera bracket with a specific structure is positioned and supported at a specific position. The first support block and the second support block support the inclined camera bracket, ensuring that the included angles between the middle hole and the side hole and the vertical direction are as small as possible, avoiding the generation of large horizontal component forces, ensuring the stable position of the camera bracket during the cleaning of the inner walls of the middle hole and the side hole, and reducing the adverse effects of shear force on the fixture and the camera bracket itself;

[0028] (2) Through the design of the bed frame in the present invention, the positioning frame and the camera bracket are installed overhead above the guide rail together, and are clamped through the sliding pin and the horizontal sliding groove. At this time, the sub-body is in the accommodation groove position between the guide rails, ensuring that there is no interference between the camera bracket and the guide rail, and the camera bracket can be fixed smoothly. Moreover, the overhead design makes the movement, disassembly of the positioning frame and the cleaning of debris more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] As Figure 1 - Figure 9 shown, this embodiment provides a numerical control punch press for processing a camera bracket, including a bed base 1, and the bed base 1 provides an installation platform;

[0041] It further includes a bed frame 2. Regarding the bed frame 2, referring to Figure 1 and Figure 4 , the bed frame 2 is fixed on the top of the bed base 1. The bed frame 2 includes a connecting plate 21. The connecting plate 21 is a horizontal plate, and equidistantly arranged guide rails 22 are installed on the top surface of the connecting plate 21, and a plurality of guide rails 22 are arranged in parallel front and back;

[0042] Regarding the positioning frame 4, referring to Figure 5 , Figure 6 and Figure 7The positioning frame 4 is slidably embedded in the bed frame 2, wherein the positioning frame 4 includes a bottom plate 41, the bottom plate 41 is two independent rectangular plates, a support block 1 43 and a support block 2 48 are installed on the top of the bottom plate 41, and the two independent bottom plates 41 are connected to each other through the support block 1 43 and the support block 2 48 to form an overhead shape similar to a gantry frame, and a middle plate 47 is installed between the support block 1 43 and the support block 2 48. The middle plates 47 are also two independent ones, and are respectively located above the two bottom plates 41. A clamping claw 46 is provided on the side of the middle plate 47 away from the bottom plate 41, and the clamping claw 46 is used to clamp the camera bracket 5 internally;

[0043] For processing component 3, refer to Figure 8 , a processing assembly 3 located above the bed 1, the processing assembly 3 includes an impact drill 32, the impact drill 32 provides a linear reciprocating drive for the drill bit, so that it has an impact ability along the axial direction, and can be used for punching processing, and a three-degree-of-freedom linear module 31 that drives the impact drill 32 to translate up and down and forward and backward. The three-degree-of-freedom linear module 31 can translate up and down and forward and backward, and the three-degree-of-freedom linear module 31 can drive the impact drill 32 to swing back and forth along the extension direction of the guide rail 22, and can swing slightly between sixty degrees and ninety degrees to adapt to the inclined hole direction;

[0044] Regarding the camera bracket 5, the camera bracket 5 is a product to be processed. The camera bracket 5 is fixed on the positioning frame 4. The camera bracket 5 includes a main body 51 and a sub-body 53 with a central axis angle of sixty degrees. The main body 51 is provided with a central hole 52 along the central axis, and the sub-body 53 is provided with a side hole 54 along the central axis. The inner walls of the central hole 52 and the side hole 54 need to be deburred. At this time, the positioning frame 4 can make the central axis of the main body 51 and the sub-body 53 have an angle of sixty degrees with the horizontal line, so as to minimize the angle between the central hole 52 and the side hole 54 and the vertical direction. The closer to the vertical state, the smaller the magnitude of the horizontal component force can be. By reducing the magnitude of the horizontal component force generated during processing, the stability of the horizontal direction after clamping can be guaranteed.

[0045] In a further embodiment, referring to Figures 2 - 7, the supporting block 1-43 has a contact surface 1-431, and the supporting block 2-48 has a contact surface 2-481. The supporting block 2-48 is higher than the supporting block 1-43. When the camera bracket 5 is placed between the supporting block 2-48 and the supporting block 1-43, one end of the camera bracket 5 will be tilted higher and the other end lower. At the same time, the contact surface 1-431 and the contact surface 2-481 are perpendicular to each other. The main body 51 has a lower end surface 1-511 and a lower end surface 2-512 that are perpendicular to each other. The lower end surface 1-511 is parallel to and in direct contact with the contact surface 1-431, and the lower end surface 2-512 is parallel to and in direct contact with the contact surface 2-481. In this way, the angular differences between the central hole 52 and the side hole 54 and the vertical line can both be 30 degrees. Because of the smaller angular difference from the vertical line, it can ensure that when being impacted by the hole-opening impact of the impact drill 32, the horizontal component force is smaller and the damage to the impact drill 32 is smaller. At the same time, the contact surfaces 1-431 and 2-481 are designed at the contact positions, and further by increasing the contact area, the stability of the support is increased.

[0046] In a further embodiment, referring to Figure 7 , a sliding opening 471 is provided in the middle plate 47 corresponding to the clamping jaw 46. The clamping jaw 46 can slide horizontally in the sliding opening 471. The design of the sliding opening 471 enables the clamping jaw 46 to be slidably limited by the middle plate 47, ensuring the horizontal precision of the sliding of the clamping jaw 46. At the same time, referring to Figure 6 , the middle plate 47 is arranged parallel to the lower end surface 2-512, which can ensure that the clamping jaw 46 can simultaneously contact the inner wall of the inclined camera bracket 5 during translation. The clamping jaw 46 is provided with a baffle 461 above the sliding opening 471. While not affecting the displacement of the clamping jaw 46, it can prevent debris above from entering the sliding opening 471, ensuring smooth sliding, and can play a limiting role on the clamping jaw 46 through direct contact with the top surface of the middle plate 47. When the clamping jaw 46 opens and squeezes the inner wall of the main body 51, the reaction force will cause the clamping jaw 46 to tilt towards the center of the central hole 52. At this time, the baffle 461 can transfer the acting force to the position of the middle plate 47, ensuring that the angle of the clamping jaw 46 will not twist, ensuring firm clamping, and improving the structural stability of the clamping jaw 46 during long-term use.

[0047] In a further embodiment, referring to Figure 2 and Figure 3 , the central hole 52 has a shape with a round upper part and a square lower part. The shape of the central hole 52 enables the clamping jaw 46 to contact a plane. Therefore, the contact surface of the clamping jaw 46 is designed as a plane, which can increase the effective contact area. There are four clamping jaws 46, and the side of the clamping jaw 46 facing the inner wall of the central hole 52 has a planar shape. The clamping jaw 46 is provided with a lining 462 at the plane. At the same time, the lining 462 is installed at the position where the clamping jaw 46 contacts the camera bracket 5. The lining 462 can adopt a wear-resistant hard structure to improve the service life, or a flexible structure that can be elastically deformed to avoid wearing the inner wall of the main body 51.

[0048] In a further embodiment, referring to Figure 7, a moving part 45 is installed at one end of the middle plate 47 facing the bottom plate 41. Among them, the moving part 45 is assembled and connected to the clamping jaws 46, that is, the moving part 45 can drive the two clamping jaws 46 located on the same middle plate 47 to approach each other. Specifically, the moving part 45 can adopt two inverted hydraulic cylinders to respectively drive the sliding actions of the two clamping jaws 46 on the middle plate 47 and make them act synchronously through a hydraulic control device. The clamping force generated by this drive is greater. At the same time, the moving part 45 can also use a lead screw equipped with two such lead screw nuts. The thread directions of the two lead screw nuts are opposite. Each of the two clamping jaws 46 is fixedly connected to a lead screw nut. When the lead screw rotates, it can drive the two clamping jaws 46 to move in opposite directions. This drive has a faster speed. Other structures that can perform synchronous drive all fall within the selection range of the moving part 45 and can be selected according to specific usage scenarios, which will not be elaborated here.

[0049] In a further embodiment, referring to Figure 4 and Figure 5 , a receiving groove 23 is formed between adjacent guide rails 22. The receiving groove 23 opens upward and has gaps at both the front and rear ends. In this way, the generated debris can directly enter the receiving groove 23. A sliding groove 24 is provided in the upper part of the vertical side wall of the guide rail 22. The bottom plate 41 is slidably installed on the top surface of the guide rail 22, and the sliding pin 42 is slidably installed in the sliding groove 24. The entire positioning frame 4 is installed above the guide rail 22 in a suspended manner. The bottom plate 41 and the middle plate 47 are provided with a slag outlet 44 below the middle hole 52. The debris generated during the processing of the middle hole 52 can pass through the slag outlet 44 and accumulate in the receiving groove 23. A sliding pin 42 is installed at the bottom end of the bottom plate 41, and the sliding pin 42 is slidably installed in the sliding groove 24, so that the debris accumulated below the receiving groove 23 will not affect the installation and disassembly of the positioning frame 4. At the same time, when cleaning the debris between the guide rails 22, it is not necessary to disassemble the positioning frame 4 on the guide rail 22, which is more convenient to use.

[0050] In a further embodiment, referring to Figure 6 , side plates 49 are provided at the end of the second supporting block 48. There are two side plates 49. The tops of the two side plates 49 extend upward beyond the top surface height of the second supporting block 48. The side plates 49 play a limiting role. When placing the camera bracket 5 above the positioning frame 4, in order to ensure that the clamping jaws 46 can be inserted into the middle hole 52, it is necessary to position the camera bracket 5 in the left-right direction, that is, the gap between the two side plates 49 is equal to the width of the main body 51. The vertical side walls on the opposite sides of the two side plates 49 are in sliding contact with the vertical outer wall of the main body 51. At this time, when placing the camera bracket 5, it can play a role of sliding limit. At the same time, when processing the side hole 54 of the sub-body 53, the impact will generate a downward pressure, and the central axis of the sub-body 53 is located outside the entity of the positioning frame 4, which will cause a downward torsional tendency of the camera bracket 5 and result in unstable support of the camera bracket 5. At this time, the side plates 49 will serve as a horizontal support structure to prevent the camera bracket 5 from twisting.

[0051] In a further embodiment, after the positioning frame 4 is installed, refer to Figure 5 and Figure 6 A bolt hole is provided at the end of the bottom plate 41, and the bolt hole is arranged perpendicular to the guide rail 22. A bolt 411 is installed in the bolt hole through a threaded connection. The bottom surface of the bolt 411 is in direct contact with the top surface of the guide rail 22. The positioning frame 4 can be directly fixed on the guide rail 22 by tightening the bolt 411, and the sliding pin 42 is clamped with the sliding groove 24 to ensure that the positioning frame 4 will not move laterally.

[0052] In a further embodiment, referring to Figure 9 To ensure the safety of processing, a protective cover is provided on the periphery of the bed base 1 and the bed frame 2, and a protective door is provided on the vertical side wall of the protective cover. The protective door is provided with an observation window. To ensure controllable operation, the protective door and the observation window are convenient for internal debugging, rapid detection of dangers and timely replacement of parts.

[0053] The working principle of this embodiment is as follows:

[0054] In order to clean the casting burrs of the middle hole 52 and the side hole 54 of the camera bracket 5, an impact drill 32 is inserted into the middle hole 52 and the side hole 54 for cleaning;

[0055] In order to ensure the stable position of the camera bracket 5 during cleaning, a positioning bracket 4 is set for support. Because there is an angle of sixty degrees between the middle hole 52 and the side hole 54, if one of the middle hole 52 and the side hole 54 is vertical, the other hole will be at an angle of sixty degrees to the vertical direction. When the hole with an inclination angle of sixty degrees is impact-processed, a large horizontal component force is easily generated. In order to prevent the camera bracket 5 from being horizontally displaced due to excessive component force, the structure of the positioning bracket 4 is optimized, and a support block 1 43 and a support block 2 48 are set to support the inclined camera bracket 5. The middle hole 52 and the side hole 54 of the camera bracket 5 are both inclined, and the angles of the central axes of the middle hole 52 and the side hole 54 relative to the vertical direction are thirty degrees, so as to reduce the strength of the horizontal component force as much as possible and ensure the stable position of the camera bracket 5 during processing;

[0056] Because the sub-body 53 is cylindrical and both the top and bottom ends protrude from the surface of the main body 51, it is inconvenient to set up a separate supporting structure. During processing, it is only fixedly connected to the main body 51 and has no direct contact with the positioning frame 4. It is in a "suspended" state. Therefore, side plates 49 and clamps 46 are provided to perform auxiliary clamping and fixing of the main body 51 in a horizontal direction. When subjected to downward impact processing, the camera bracket 5 is prevented from twisting in the direction of the sub-body 53, thereby ensuring the stable position during processing.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
