Description

Technical Field

[0001] This utility model relates to the field of hardware processing, and more specifically, to a milling machine fixture for hardware processing. Background Technology

[0002] When machining hardware parts, milling machines are used to process the overall shape, and a fixing fixture is used to pre-fix the workpiece before machining with a cutting tool. Patent publication number CN210173030U discloses a fixing fixture for a hardware milling machine, including a base, a fixing clamping device, an auxiliary adjusting clamping device, and a positioning device. The base has connecting parts on both sides, a positioning device on one side above the base, and a fixing clamping device on the other side above the base. Auxiliary adjusting clamping devices are symmetrically arranged on the base between the fixing clamping device and the positioning device. This utility model can clamp and fix shaft-type hardware parts through the upper and lower fixing seats of the fixing clamping device. The fine-tuning bolts and internal threaded sleeve fixing blocks of the auxiliary adjusting clamping device can finely adjust and fix the side walls of the shaft-type hardware parts, improving the clamping stability of the shaft-type hardware parts. The multiple sets of positioning slots of the positioning device can meet the fixing and clamping of shaft-type hardware parts of different diameters, while having high positioning stability and high practicality.

[0003] While existing technologies can effectively process metal parts, the fixture can only process shaft-type metal parts. When encountering composite workpieces, such as workpieces combining shafts and plates, if the clamping surface is flat, ordinary curved fixtures cannot effectively clamp them. Changing fixtures would also consume a lot of time. Therefore, existing fixtures have certain limitations and cannot adapt to the clamping needs of different types of workpieces, reducing the practicality of the device. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a milling machine fixture for hardware parts processing. It can quickly change the clamping surface of the fixture, and when facing different types of workpieces, it can achieve a fast and effective stable clamping effect without the need for the operator to disassemble and reassemble the entire fixture. This improves the overall practicality of the fixture. Furthermore, the fixture angle can be rotated and adjusted, further enhancing its overall applicability. As a result, the equipment can meet the processing needs of more hardware parts, greatly improving the practicality of the device.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A milling machine fixture for machining hardware parts includes a clamping platform. A rotating rod is rotatably mounted inside the clamping platform. A double-threaded screw is integrally formed inside the rotating rod. A sliding block is threaded onto the surface of the double-threaded screw. A motor is fixedly mounted on the top outer wall of the sliding block. A gear one is fixedly sleeved on the output shaft of the motor. A gear two meshes with the surface of the gear one. A connecting shaft is fixedly mounted on the outer side of the gear two. A disc is fixedly mounted on the outer end of the connecting shaft. A storage box is fixedly mounted on the outer side of the disc. A turntable is rotatably mounted inside the disc. A limit ring is fixedly mounted on the top surface inside the storage box. Sliding grooves are formed on the inner walls of both the left and right sides of the storage box.

[0009] Furthermore, a T-shaped rod is fixedly installed at the top outer side of the collection box, and a convex plate is fixedly installed at both ends of the T-shaped rod. A connecting ring is rotatably installed in the middle of the T-shaped rod, and a torsion spring is fixedly connected between the connecting ring and the convex plate.

[0010] Furthermore, a flat clamping block is fixedly installed at the bottom end of the connecting ring, and a support ball is fixedly installed on the inner side of the bottom end of the flat clamping block.

[0011] Furthermore, a threaded rod is fixedly installed on one side of the turntable, and limit plates are fixedly installed on both the left and right ends of the threaded rod. A transmission ring is threaded onto the surface of the threaded rod, and the limit plate is rotatably installed inside the limit ring. A U-shaped frame is fixedly installed at the bottom end of the transmission ring, and both the left and right ends of the U-shaped frame are slidably installed inside the sliding groove.

[0012] Furthermore, the same arc-shaped clamping block is fixedly installed on the inner side of both U-shaped frames, and push plates are fixedly installed on the left and right sides of the top of the arc-shaped clamping block.

[0014] Furthermore, the outer center of the arc-shaped clamping block and the inner center of the supporting ball are on the same horizontal line.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution utilizes the rotating storage box to drive the arc-shaped clamping block to push out, replacing the flat clamping block, thereby achieving the purpose of quickly changing the fixture. The operation is simple and does not require the staff to disassemble and replace the entire fixture, saving disassembly and assembly time, reducing the work difficulty of the staff, and further improving the processing efficiency of the equipment.

[0018] (2) This solution utilizes the center of the support ball in conjunction with the arc-shaped clamping block to ensure that even if the flat clamping block has the function of rotation, its center can also have an effective clamping support effect when performing flat clamping, preventing the gap between it and the arc-shaped clamping block from affecting the clamping effect of the flat clamping block itself.

[0019] (3) This solution utilizes gear two to work with a motor to drive gear one to rotate and change the clamping surface, thereby changing the clamping direction of the arc-shaped clamping block and making it adaptable to a wider range of clamping needs, thus further improving the overall practicality of the device.

[0029] Example 1:

[0030] Please see Figure 1-4 A milling machine fixture for processing hardware parts includes a clamping platform 1. A rotating rod 2 is rotatably mounted inside the clamping platform 1. A double-threaded screw 3 is integrally formed inside the rotating rod 2. A sliding block 4 is threaded onto the surface of the double-threaded screw 3. A motor 5 is fixedly mounted on the outer wall of the top of the sliding block 4. A gear 6 is fixedly sleeved on the output shaft of the motor 5. A gear 7 meshes with the surface of the gear 6. A connecting shaft 8 is fixedly mounted on the outer side of the gear 7. A disc 9 is fixedly mounted on the outer end of the connecting shaft 8. A storage box 10 is fixedly mounted on the outer side of the disc 9. A turntable 11 is rotatably mounted inside the disc 9. A limit ring 101 is fixedly mounted on the top surface inside the storage box 10. Sliding grooves 102 are formed on the inner walls of both the left and right sides of the storage box 10.

[0031] It should be noted that the clamping platform 1 in this application is the same as the worktable in the prior art. In addition to the clamping device, its surface is also provided with related processing components and positioning mechanisms, which are all existing mature technologies and are predictable conventional means. Therefore, this application will not elaborate on these aspects.

[0032] Specifically, using gear 6 in conjunction with gear 7 can drive the entire disc 9 to rotate the storage box 10, thereby changing the angle of the corresponding internal clamping blocks, so that it can achieve an effective clamping effect when clamping different types of workpieces.

[0033] A T-shaped rod 103 is fixedly installed at the top outer side of the storage box 10. A convex plate 108 is fixedly installed at both ends of the T-shaped rod 103. A connecting ring 104 is rotatably installed in the middle of the T-shaped rod 103. A torsion spring 105 is fixedly connected between the connecting ring 104 and the convex plate 108. A flat clamping block 106 is fixedly installed at the bottom end of the connecting ring 104. A support ball 107 is fixedly installed on the inner side of the bottom end of the flat clamping block 106. A threaded rod 1101 is fixedly installed on one side of the turntable 11. Limiting plates 1102 are fixedly installed at both ends of the threaded rod 1101. A transmission ring 11 is threaded onto the surface of the threaded rod 1101. 03, the limiting disk 1102 is rotatably installed inside the limiting ring 101, the bottom end of the transmission ring 1103 is fixedly installed with a U-shaped frame 1104, the left and right ends of the U-shaped frame 1104 are slidably installed inside the sliding groove 102, the inner sides of the two U-shaped frames 1104 are fixedly installed with the same arc-shaped clamping block 1105, the left and right sides of the top of the arc-shaped clamping block 1105 are fixedly installed with push plates 1106, the outer end of the top surface of the push plate 1106 is set with a rounded corner structure, the inner end of the top surface of the push plate 1106 is integrally formed with a cylinder, the outer center of the arc-shaped clamping block 1105 and the inner center of the support ball 107 are on the same horizontal line;

[0034] Specifically, the limiting ring 101 limits the rotation of the threaded rod 1101, ensuring stable transmission. Secondly, the sliding groove 102 limits the movement of the arc-shaped clamping block 1105, ensuring it can only perform linear movement along a single axis and cannot rotate. The fact that the center of the support ball 107 and the arc-shaped clamping block 1105 are on the same horizontal line ensures that the gap between the center of the flat clamping block 106 and the arc-shaped clamping block 1105 still provides effective support when the flat clamping block 106 is clamping, preventing insufficient local support from causing problems. The deformation of the flat clamp 106 improves the service life of the overall device. Finally, the rounded corner structure of the outer end of the push plate 1106 makes it smoother when it contacts the inner wall of the flat clamp 106, without excessive scratching. Secondly, as the arc-shaped clamp 1105 moves outward, the horizontal height of the push plate 1106 gradually increases, thereby changing the overall position of the flat clamp 106 and making it open against the torsion spring 105. When resetting, the torsion spring 105 provides power, eliminating the need for manual resetting and adjustment by the operator, thus improving the convenience of changing the overall clamp.

[0035] The working principle of this utility model is as follows: the operator selects a suitable clamping block according to the clamping surface of the hardware parts to be clamped. If it is a shaft part, the turntable 11 can be rotated to drive the threaded rod 1101 to rotate, which, together with the transmission ring 1103, drives the arc-shaped clamping block 1105 to be pushed out from the inside of the storage box 10. During this process, the outer end of the push plate 1106 first fits against the inner wall of the flat clamping block 106, and then, as the moving distance increases, the cylinder at the inner end of the push plate 1106 completely covers the flat clamping block 10. 6. Spread out so that the connecting ring 104 at the top applies torque to the torsion spring 105. Then, the arc-shaped clamping block 1105 is pushed out to clamp the shaft-type parts. When flat clamping is required, simply reset the arc-shaped clamping block 1105. The flat clamping block 106 is in a vertical state. Then, the center is supported on the surface of the arc-shaped clamping block 1105 by the support ball 107. Finally, rotate the double-threaded screw 3 to drive the sliding block 4 to move, reduce the distance between the two clamping blocks, and gradually fit them against the surface of the workpiece to complete the clamping.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
