Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and more specifically, to a fixing fixture for machining non-standard threads of spare parts. Background Technology

[0002] Fixtures for non-standard thread machining of spare parts are devices designed to hold specific workpieces (spare parts) and provide stable and precise positioning when machining non-standard threads. Spare parts refer to customized parts that actually need to be machined. They usually have special shapes or sizes and require special fixtures to adapt to them.

[0003] Among them, the patent with announcement number CN219703734U discloses a fixing fixture for internal thread processing, including a U-shaped plate, a first rotating arm and a second rotating arm. The two second rotating arms are rotatably connected between the two first rotating arms through a rotating shaft. A bearing block is rotatably connected between the two second rotating arms through a rotating shaft. An internal threaded column is rotatably connected between the ends of the two first rotating arms through a rotating shaft. A threaded rod is threadedly connected to the inner wall of the internal threaded column, and the end of the threaded rod is rotatably connected to the bearing block.

[0004] When in use, this structure has a limiting mechanism for adjusting the position of the clamped hardware, which allows the hardware to rotate and adjust its position after being clamped. This avoids the trouble of moving the threading equipment due to improper positioning and improves the efficiency of subsequent internal thread processing. However, this structure is not easy to lift the workpiece when clamping it, and the force point of the workpiece is limited to the clamping area. Displacement is easy to occur when drilling. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a fixing fixture for non-standard thread processing of spare parts, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a fixing fixture for non-standard thread processing of spare parts, including a base, a first pad is fixedly provided at one top end of the base, a second pad is provided on one side of the first pad, and a support component is provided on both the first pad and the second pad.

[0007] The support assembly includes a support plate disposed on the top of the second pad, two connecting plates are fixedly disposed on the support plate, and each connecting plate is provided with a clamping rod. Anti-slip teeth are provided on the opposite side of the two clamping rods, and the anti-slip teeth are close to the ends of the clamping rods.

[0008] A traction block is provided between the two clamping rods. A sliding groove is provided at the end of the clamping rod facing the traction block. The traction block and the clamping rod are slidably connected through the sliding groove. A knob is threaded to one end of the support plate. One end of the knob extends to the traction block and is rotatably connected to the traction block.

[0009] As can be seen, in the above technical solution, the clamping rod can rotate along the axis point where it connects with the limit pin due to the traction force when the traction block is displaced. This causes the two clamping rods to move closer together to clamp the parts, while the bottom of the parts can abut against the support plate, thus lifting the parts. This effectively prevents the workpiece from shifting during drilling. At the same time, the anti-slip teeth on the clamping rod increase the friction between the clamping rod and the parts, ensuring the stability of the parts when clamped. The spring allows the clamping rod to return to its original position when the traction block is not in contact with it, making it easier to remove the clamped parts and improving the convenience of parts processing.

[0010] Optionally, in one possible implementation, each of the two clamping rods is rotatably connected to a limiting pin, the bottom end of which extends to a connecting plate and is threadedly connected to the connecting plate. Each of the two clamping rods is provided with a spring at its top, the spring being hooked onto the clamping rod. One end of the base is bolted to a motor, the output end of which is provided with a lead screw. The lead screw passes through the second pad and extends to the first pad, the second pad being threadedly connected to the lead screw.

[0011] As can be seen, in the above technical solution, when the lead screw rotates, it drives the second pad to adjust its position on the first pad, thereby adjusting the distance between the support components on the first and second pads and facilitating the support components to support the parts.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up support components, the overall design is simple and the structure is reasonable compared with the existing technology. Through the corresponding cooperation of each structure, the clamping rod can rotate along the axis point where the clamping rod and the limit pin are connected due to the traction force when the traction block is displaced. This causes the two clamping rods to move closer to each other to clamp the parts, while the bottom of the parts can abut against the support plate, realizing the function of lifting the parts and effectively preventing the workpiece from shifting when drilling.

[0014] Meanwhile, the anti-slip teeth on the clamping rod increase the friction between the clamping rod and the parts, ensuring the stability of the parts when clamped. The spring allows the clamping rod to return to its original position through its own elasticity when the traction block is not in contact with the clamping rod, so that the clamped parts can be removed, improving the convenience of parts processing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figures 1-4 The fixture shown is a non-standard thread processing fixture for spare parts. It uses support components on the first pad 2 and the second pad 3 to clamp the spare parts by having two clamping rods 6 close to each other. The bottom of the spare parts can abut against the support plate 4 to lift the spare parts, which can effectively prevent the workpiece from shifting when drilling. At the same time, the anti-slip teeth 9 on the clamping rods 6 can increase the friction between the clamping rods 6 and the spare parts, ensuring the stability of the spare parts when clamped. The spring 8 can make it easy for the clamping rods 6 to return to their original position when the traction block 10 is not in contact with the clamping rods 6, so that the clamped spare parts can be removed, improving the convenience of spare parts processing. The specific structure of the components is as follows.

[0023] The support assembly includes a support plate 4 set on the top of the second pad 3. Two connecting plates 5 are fixedly set on the support plate 4, and each connecting plate 5 is provided with a clamping rod 6. Anti-slip teeth 9 are provided on the opposite side of the two clamping rods 6, and the anti-slip teeth 9 are close to the end of the clamping rod 6.

[0024] A traction block 10 is provided between the two clamping rods 6. A sliding groove is provided at the end of the clamping rod 6 facing the traction block 10. The traction block 10 and the clamping rod 6 are slidably connected through the sliding groove. A knob 11 is threadedly connected to one end of the support plate 4. One end of the knob 11 extends to the traction block 10 and is rotatably connected to the traction block 10.

[0025] Both clamping rods 6 are rotatably connected to limit pins 7. The bottom end of the limit pin 7 extends to the connecting plate 5 and is threadedly connected to the connecting plate 5. Both clamping rods 6 are provided with springs 8 at their tops. The springs 8 are hooked on the clamping rods 6. One end of the base 1 is equipped with a motor 12 by bolts. The output end of the motor 12 is provided with a lead screw 13. The lead screw 13 passes through the second pad 3 and extends to the first pad 2. The second pad 3 is threadedly connected to the lead screw 13.

[0026] The specific working principle is as follows: When processing the parts, according to the size of the parts, the motor 12 drives the lead screw 13. When the lead screw 13 rotates, it drives the second pad 3 to adjust its position on the first pad 2, thereby realizing the function of adjusting the distance between the support components on the first pad 2 and the second pad 3, which facilitates the function of the support components supporting the parts.

[0027] Simultaneously, by rotating the knob 11, the position of the traction block 10 is adjusted, so that the traction block 10 can abut against one end of the clamping rod 6. Due to the traction force when the traction block 10 is displaced, the clamping rod 6 can rotate along the axis point where the clamping rod 6 is connected to the limit pin 7, so that the two clamping rods 6 move closer to each other to clamp the parts, and the bottom of the parts can abut against the support plate 4, realizing the function of lifting the parts, which can effectively prevent the workpiece from shifting when drilling.

[0028] Meanwhile, the anti-slip teeth 9 on the clamping rod 6 increase the friction between the clamping rod 6 and the parts, ensuring the stability of the parts when clamped. The spring 8 allows the clamping rod 6 to be elastically reset when the traction block 10 is not in contact with the clamping rod 6, so that the clamped parts can be removed, improving the convenience of parts processing.

[0029] Unlike existing technologies, this application discloses a fixing fixture for non-standard thread processing of spare parts. The spare parts are clamped by two clamping rods 6 that are brought close together, while the bottom of the spare parts can abut against the support plate 4, thus lifting the spare parts and effectively preventing displacement of the workpiece during drilling. At the same time, the anti-slip teeth 9 provided on the clamping rods 6 increase the friction between the clamping rods 6 and the spare parts, ensuring the stability of the spare parts when clamped. The spring 8 is provided so that when the traction block 10 is not in contact with the clamping rods 6, the clamping rods 6 can be elastically reset by the spring 8, so that the clamped spare parts can be removed, improving the convenience of spare parts processing.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
