Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture for processing tubular parts. Background Technology

[0002] In the field of machining, tubular parts are a common type of component, widely used in many industries. Their machining quality directly affects the performance and safety of the entire product. During the machining of tubular parts, fixtures play a crucial role, as they can accurately position and firmly clamp the parts, ensuring the accuracy and stability of the machining process.

[0003] Most clamps on the market have a fixed length. This design is not very adaptable when dealing with tubular parts of different lengths. When clamping long tubular parts, the fixed-length clamp cannot provide a sufficient and uniform clamping force distribution, which can easily lead to uneven force on the parts, resulting in unstable clamping and seriously affecting the machining accuracy of the parts. Therefore, it is necessary to design a clamp for machining tubular parts to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a jig for machining tubular parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jig for processing tubular parts, including a support member, on the inner side of which two sets of length-adjustable jigs are arranged in a mirror-symmetrical manner. The jig includes a main clamping block and two sets of auxiliary clamping blocks. Each side of the main clamping block is connected to a set of auxiliary clamping blocks in a limiting sliding manner, and the main clamping block and the auxiliary clamping blocks can be locked in position by a locking component, thereby achieving reliable locking of the jig in both extended and shortened states.

[0006] Preferably, both the main clamping block and the auxiliary clamping block are designed with a V-shaped structure. The auxiliary clamping block has a slider integrally formed on the side facing the main clamping block. The slider can be slidably inserted into the side cavity of the main clamping block and its position is locked by the locking component.

[0007] Preferably, the locking assembly includes a slide groove, a spring, a locking tongue, and a locking hole. At both ends of the secondary clamping block, two sets of the slide grooves are respectively opened for different states of clamp extension and retraction. A set of the springs is installed in the inner cavity of each set of the slide grooves. The free end of the springs is connected to a set of the locking tongues. The locking tongues can be inserted into the locking holes opened on the main clamping block corresponding to the extended and retracted states of the clamp.

[0008] Preferably, the opposite sides of the two sets of main clamping blocks are connected to the support member by means of a telescopic assembly. The telescopic assembly consists of an electric push rod and a connecting block. Two sets of electric push rods are installed in a mirror-symmetrical manner at both ends of the support member. The output end of each set of electric push rods is connected to a set of connecting blocks, and the connecting blocks are stably connected to the outside of the main clamping blocks.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The adjustable length design of this utility model can adapt to tubular parts of different lengths, solving the problem of poor adaptability of most fixed-length clamps on the market. The clamp length can be reasonably adjusted according to the length of the tubular parts, so that the clamping force is evenly distributed, avoiding uneven force on the parts, improving clamping stability, and ensuring the machining accuracy of the parts.

[0010] The V-shaped main and auxiliary clamping blocks of this utility model provide better encapsulation and stability when clamping tubular parts, making the parts less prone to shaking during processing and improving processing accuracy. The length adjustment is achieved through the sliding cooperation between the slider and the side cavity, which is simple and convenient to operate. The locking component uses the elastic force of the spring to push the locking tongue into the locking hole for locking. It can automatically lock when adjusted to the appropriate position, and the locking is firm, avoiding the problem of processing quality being affected by the loose clamp. This allows the clamp to be flexibly adjusted according to tubular parts of different lengths, adapting to various processing conditions and improving the versatility and practicality of the clamp.

[0011] This utility model features an electric linear actuator that enables automated adjustment, reduces manual operation and errors, and improves efficiency. The electric linear actuator has high motion precision and can accurately control the movement distance of the main clamping block, thereby improving machining accuracy. The connecting block provides a stable connection, and the mirror-mounted electric linear actuator ensures smooth movement of the main clamping block. The clamping distance can be flexibly adjusted to adapt to the machining of various sizes of tubular parts. Attached Figure Description

[0014] 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.

[0015] Example 1 Please refer to Figure 1-4 As shown, this utility model provides a jig for processing tubular parts, including a support member 1. Two sets of length-adjustable jigs are arranged symmetrically on the inner side of the support member 1. The jig includes a main clamping block 2 and two sets of auxiliary clamping blocks 3. Each side of the main clamping block 2 is connected to a set of auxiliary clamping blocks 3 by a limiting sliding method. The main clamping block 2 and the auxiliary clamping blocks 3 can be locked in position by a locking component, thereby realizing reliable locking of the jig in the extended and shortened states.

[0016] The support 1 has two sets of length-adjustable clamps on its inner side. The main clamp 2 is connected to a set of auxiliary clamps 3 on each side by a limiting sliding method. The clamp length can be extended or shortened by the relative sliding of the main clamp 2 and the auxiliary clamp 3. When the clamp is adjusted to a suitable length, the position of the main clamp 2 and the auxiliary clamp 3 is locked by the locking component to ensure that the clamp is reliably fixed in the extended or shortened state.

[0017] The adjustable length design can adapt to tubular parts of different lengths, solving the problem of poor adaptability of most fixed-length fixtures on the market. The fixture length can be reasonably adjusted according to the length of the tubular parts, so that the clamping force is evenly distributed, avoiding uneven force on the parts, improving clamping stability, and ensuring the machining accuracy of the parts.

[0018] Specifically, both the main clamping block 2 and the auxiliary clamping block 3 are designed with a V-shaped structure. The auxiliary clamping block 3 has an integrally formed slider 4 on the side facing the main clamping block 2. The slider 4 can be slidably inserted into the side cavity of the main clamping block 2 and is locked in position by a locking component. The locking component includes a slide groove 5, a spring 6, a locking tongue 7, and a locking hole 8. At both ends of the auxiliary clamping block 3, two sets of slide grooves 5 are opened for different states of clamp extension and retraction. A set of springs 6 is installed in the inner cavity of each set of slide grooves 5. The free end of the spring 6 is connected to a set of locking tongues 7. The locking tongues 7 can be inserted into the locking holes 8 opened on the main clamping block 2 for the corresponding clamp extension and retraction states.

[0019] The main clamping block 2 and the auxiliary clamping block 3 are designed with a V-shaped structure. The slider 4 of the auxiliary clamping block 3 facing the main clamping block 2 can be slidably inserted into the side cavity of the main clamping block 2. When it is necessary to adjust the length of the clamp, an external force is applied to the auxiliary clamping block 3 to overcome the elastic force of the spring 6 in the slide groove 5, so that the locking tongue 7 exits from the locking hole 8 at the current position on the main clamping block 2. The auxiliary clamping block 3 is continued to be pushed, and the slider 4 slides in the side cavity of the main clamping block 2 to realize the extension or shortening operation of the clamp. When the auxiliary clamping block 3 slides to the appropriate position, corresponding to the extension or shortening state of the clamp, the corresponding locking hole 8 on the main clamping block 2 is aligned with the slide groove 5. At this time, the spring 6 in the slide groove 5 pushes the locking tongue 7 into the corresponding locking hole 8 under its own elastic force, thereby realizing the position locking of the main clamping block 2 and the auxiliary clamping block 3, so that the clamp remains stable in the adjusted length state.

[0020] The V-shaped main clamping block 2 and auxiliary clamping block 3 design provides better encapsulation and stability when clamping tubular parts, making the parts less prone to shaking during processing and improving processing accuracy. The length adjustment is achieved through the sliding cooperation of the slider 4 and the side cavity, which is simple and convenient to operate. The locking component uses the elastic force of the spring 6 to push the locking tongue 7 into the locking hole 8 for locking. It can automatically lock when adjusted to the appropriate position, and the locking is firm, avoiding the problem of processing quality being affected by the loosening of the clamp. This allows the clamp to be flexibly adjusted according to tubular parts of different lengths, adapting to various processing conditions and improving the versatility and practicality of the clamp.

[0021] Among them: the two sets of main clamping blocks 2 are connected to the support 1 by means of telescopic components. The telescopic components are composed of electric push rods 9 and connecting blocks 10. At both ends of the support 1, two sets of electric push rods 9 are installed in a mirror symmetrical manner. The output end of each set of electric push rods 9 is connected to a set of connecting blocks 10, and the connecting blocks 10 are firmly connected to the outside of the main clamping blocks 2.

[0022] The output end of the electric push rod 9 extends and retracts, and the main clamping block 2 moves on the support member 1 via the connecting block 10. The two sets of electric push rods 9, which are mirror-mounted at both ends of the support member 1, work synchronously, so that the two sets of main clamping blocks 2 move synchronously towards or away from each other, thereby adjusting the clamping distance.

[0023] The electric linear actuator 9 enables automated adjustment, reducing manual operation and errors, and improving efficiency. The electric linear actuator 9 has high motion precision and can accurately control the movement distance of the main clamping block 2, improving machining accuracy. The connecting block 10 provides a stable connection. The mirror-mounted electric linear actuator 9 makes the main clamping block 2 move smoothly and can flexibly adjust the clamping distance to adapt to the machining of various sizes of tubular parts.

[0024] Working principle: The main clamping block 2 and the auxiliary clamping block 3 are designed with a V-shaped structure. The slider 4 of the auxiliary clamping block 3 facing the main clamping block 2 can be slidably inserted into the side cavity of the main clamping block 2. When it is necessary to adjust the length of the clamp, an external force is applied to the auxiliary clamping block 3 to overcome the elastic force of the spring 6 in the slide groove 5, causing the locking tongue 7 to exit from the locking hole 8 at the current position on the main clamping block 2. The auxiliary clamping block 3 is then pushed, and the slider 4 slides in the side cavity of the main clamping block 2, realizing the extension or shortening operation of the clamp. When the auxiliary clamping block 3 slides to the appropriate position, the clamp is in the extended or shortened state. When the corresponding locking hole 8 on the main clamping block 2 is aligned with the slide groove 5, the spring 6 in the slide groove 5 pushes the locking tongue 7 into the corresponding locking hole 8 under its own elastic force, thereby locking the position of the main clamping block 2 and the auxiliary clamping block 3, so that the clamp remains stable in the adjusted length state. The output end of the electric push rod 9 extends and retracts, and drives the main clamping block 2 to move on the support member 1 through the connecting block 10. The two sets of electric push rods 9 installed in mirror at both ends of the support member 1 work synchronously, so that the two sets of main clamping blocks 2 move synchronously towards or away from each other, and adjust the clamping distance.
