Description

Technical Field

[0001] This utility model relates to the field of torsion testing technology, and specifically to an automatic torsion testing machine. Background Technology

[0002] In cable production and testing, torsion testing is a common testing procedure. Cables are often subjected to torsion during transportation or use, so it is essential to confirm the torsion resistance of the cable. Traditional torsion testing usually involves fixing both ends of the cable and then twisting one end of the cable to test whether its performance meets the requirements.

[0003] The existing patent number CN116429601A discloses a torsion resistance cable performance testing device and testing method, including a test bench and a servo motor. The servo motor is fixedly mounted on the top of the test bench by a bracket, and the output shaft of the servo motor is fixedly connected to a threaded rod by a coupling. This invention relates to the field of cable testing technology. By setting a self-clamping mechanism, a torsion mechanism, a feeding mechanism, and a limiting mechanism on the top of the test bench, the device can automatically tighten and twist cables during batch testing through the coordinated action of the self-clamping mechanism, the torsion mechanism, and the limiting mechanism. This makes the overall testing process more tightly connected and efficient. Furthermore, the self-clamping mechanism, the torsion mechanism, and the limiting mechanism work synchronously and simultaneously with the feeding mechanism, enabling the device to achieve automatic loading and unloading, automatic tightening and loosening, and synchronous torsion testing.

[0004] The aforementioned patent has some defects in actual use. The self-clamping mechanism lacks a limiting and fixing function, which makes it easy to loosen and detach. At the same time, the compression ring cannot easily follow the rotation during rotation, which can easily affect the actual compression and fixing effect and cause unexpected loosening. Furthermore, the spacing of the clamping mechanism is relatively fixed and cannot be easily adjusted according to the tested length, resulting in poor applicability of the device and difficulty in meeting diverse cable torsion testing needs. Utility Model Content

[0005] The purpose of this invention is to provide an automatic torsion testing machine that solves the problems of existing torsion device clamping mechanisms lacking a fixed structure, making them prone to loosening and lacking an adjustment structure, thus failing to meet diverse testing needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic torsion testing machine, comprising a worktable, with connecting rings installed at both ends of the top of the worktable, a plurality of extrusion blocks installed on one side of the connecting rings, and an extrusion ring provided on the side of the extrusion blocks away from the connecting rings, and receiving grooves opened inside the connecting rings corresponding to the extrusion blocks, with sliding plates slidably connected inside the receiving grooves, a drive assembly installed at one end of the top of the worktable, and connecting rods provided on both sides of the top of the worktable.

[0007] Each of the extrusion blocks is fixedly connected to a sliding block at one end edge near the receiving groove, and the sliding block is provided with teeth on one side near the sliding plate that correspond to the side of the sliding plate.

[0008] A mounting plate is fixedly connected to the top of the workbench near the drive assembly, and a movable plate is slidably connected to the top of the workbench away from the mounting plate.

[0009] The drive assembly includes a rotating gear ring, a drive gear is meshed with the bottom of the rotating gear ring, the rotating gear ring is fixedly connected to the outer wall of the connecting ring, and a drive motor is installed on one side of the drive gear.

[0010] Preferably, an electric push rod is installed at the end of the connecting rod away from the drive assembly. The inner protruding end of the electric push rod is fixedly connected to the connecting rod. A fixing plate is installed on the outer wall of the electric push rod, and the electric push rod is fixedly connected to the top of the worktable through the fixing plate.

[0011] Preferably, the outer wall of each extrusion ring is rotatably connected to a sleeve ring, and the outer wall of the connecting ring is sleeved with a push ring, the push ring being in contact with one side of the sliding plate;

[0012] The connecting rod on one side of the top of the workbench is slidably connected to two sleeve rings, and the connecting rod on the side away from the sleeve rings is slidably connected to the outer wall of two push rings. The sleeve rings and push rings are threaded with compression bolts on the side near the connecting rod, and one end of the compression bolt is in contact with the outer wall of the connecting rod.

[0013] Preferably, the bottom of the movable plate is bent to one side, and the bent part of the movable plate is threaded with a fixing bolt. The fixing bolt passes through the movable plate and fits against the top of the workbench. The center of the movable plate is fixedly connected to the connecting ring, and the mounting plate is rotatably connected to the connecting ring through a bearing.

[0014] Preferably, a compression spring is fixedly installed on the side of the compression block near the center of the connecting ring, the sliding block is slidably connected to the receiving groove at the center of the connecting ring, the outer wall of the end of the compression block away from the connecting ring is inclined towards the center of the connecting ring, and the compression ring and the compression block are slidably connected in contact.

[0015] Preferably, the sliding plate is slidably connected to the inside of the receiving groove along the horizontal direction, and a plurality of telescopic springs are provided on the side of the sliding plate away from the sliding block, and the two ends of the telescopic springs are fixedly connected to the side wall of the receiving groove and the sliding plate respectively, and the top of the sliding plate extends out of the inside of the receiving groove and fits against the side of the push ring.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. As the compression block moves towards the center of the connecting ring, the sliding block follows it, compressing the compression spring. The teeth on the side of the sliding plate tilt downwards, effectively preventing the sliding block from moving in the opposite direction and thus preventing the compression block from loosening. Simultaneously, the compression ring also prevents the compression block from moving in the opposite direction, maintaining tight compression and fixation of the cable. Activating the electric push rod moves the connecting rod, causing it to move the compression ring in the opposite direction. This pushes the two push rings, which in turn move the sliding plate, releasing the engagement between the sliding plate and the teeth on the side of the sliding block. This releases the restriction on the sliding block, allowing it to move in the opposite direction under the push of the compression spring, thus releasing the cable and facilitating twisting operations.

[0018] 2. The compression ring presses and fixes the compression block, allowing for the compression and fixing of cables of different diameters. This is suitable for testing various cables. When using cables of different lengths, the fixing bolts can be easily rotated to release the moving plate from the worktable. Rotating the compression bolts releases the fixing of the connecting rod, sleeve ring, and push ring, allowing for easy adjustment of the moving plate's position. This causes the connecting ring to move, which in turn moves the compression block, adjusting its compression and fixing position. This allows for adjustment of the distance between the compression blocks on the outer walls of the two connecting rings, facilitating the clamping and fixing of cables of different lengths and simplifying testing.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The automatic torsion testing machine shown includes a worktable 1. Connecting rings 2 are installed at both ends of the top of the worktable 1. Multiple extrusion blocks 3 are installed on one side of each connecting ring 2. Extrusion rings 4 are located on the side of each extrusion block 3 away from the connecting ring 2. Receiving grooves 201 are formed inside the connecting rings 2 at positions corresponding to the extrusion blocks 3. Sliding plates 5 are slidably connected inside the receiving grooves 201. A drive assembly 6 is installed at one end of the top of the worktable 1. Connecting rods 7 are provided on both sides of the top of the worktable 1. The edges of the extrusion blocks 3 near the receiving grooves 201 are fixed. A sliding block 301 is connected, and the side of the sliding block 301 near the sliding plate 5 is provided with teeth corresponding to the side of the sliding plate 5; a mounting plate 101 is fixedly connected to the top of the worktable 1 near the drive assembly 6, and a moving plate 102 is slidably connected to the top of the worktable 1 away from the mounting plate 101; the drive assembly 6 includes a rotating gear ring 601, a drive gear 602 is meshed with the bottom of the rotating gear ring 601, the rotating gear ring 601 is fixedly connected to the outer wall of the connecting ring 2, and a drive motor 603 is installed on one side of the drive gear 602.

[0029] The teeth on the side of the sliding plate 5 are inclined to the bottom, which can effectively prevent the sliding block 301 from moving in the opposite direction, thereby preventing the pressing block 3 from loosening. At the same time, the pressing ring 4 can also prevent the pressing block 3 from moving in the opposite direction, thus maintaining the pressing block 3's tight pressing on the cable and keeping it fixed, which facilitates twisting operations. When it is necessary to release the fixation, the electric push rod 701 is activated to drive the connecting rod 7 to move, which in turn causes the connecting rod 7 to drive the pressing ring 4 to move in the opposite direction, and then pushes the two push rings 501 to move, which in turn causes the push rings 501 to drive the sliding plate 5 to move, releasing the engagement between the sliding plate 5 and the teeth on the side of the sliding block 301, thus releasing the restriction on the sliding block 301. Under the push of the pressing spring 302, the sliding block 301 moves in the opposite direction, thereby releasing the pressing block 3's fixation on the cable, thus facilitating the fixing and disconnection of the cable.

[0030] Rotating the fixing bolt 103 releases the fixation between the moving plate 102 and the worktable 1. Rotating the clamping bolt 702 releases the fixation between the connecting rod 7 and the sleeve ring 401 and the pushing ring 501, thereby facilitating the adjustment of the position of the moving plate 102. This causes the connecting ring 2 to move accordingly, which in turn causes the clamping block 3 to be displaced, thereby adjusting the clamping and fixing position of the clamping block 3. This allows for the adjustment of the distance between the clamping blocks 3 on the outer walls of the two connecting rings 2, making it convenient to clamp and fix cables of different lengths and facilitating testing.

[0031] like Figure 3 , Figure 4 As shown, an electric push rod 701 is installed at the end of the connecting rod 7 away from the drive assembly 6. The inner protruding end of the electric push rod 701 is fixedly connected to the connecting rod 7. A fixing plate 104 is installed on the outer wall of the electric push rod 701. The electric push rod 701 is fixedly connected to the top of the workbench 1 through the fixing plate 104. A sleeve ring 401 is rotatably connected to the outer wall of the extrusion ring 4. A push ring 501 is sleeved on the outer wall of the connecting ring 2. The push ring 501 is in contact with one side of the sliding plate 5. The connecting rod 7 on one side of the top of the workbench 1 is slidably connected to the two sleeve rings 401 through it. One side of the connecting rod 7 is slidably connected to the outer wall of the two push rings 501. The sleeve ring 401 and the push ring 501 are threaded with a compression bolt 702 on the side near the connecting rod 7. One end of the compression bolt 702 is in contact with the outer wall of the connecting rod 7. When the electric push rod 701 is activated, the connecting rod 7 is moved, which causes the connecting rod 7 to move the compression ring 4 in the opposite direction, and then pushes the two push rings 501 to move, which causes the push rings 501 to move the sliding plate 5, thereby releasing the jamming between the sliding plate 5 and the side teeth of the sliding block 301, thus releasing the restriction on the sliding block 301.

[0032] like Figure 1 , Figure 2As shown, the bottom of the movable plate 102 is bent to one side, and the bent part of the movable plate 102 is threaded with a fixing bolt 103. The fixing bolt 103 passes through the movable plate 102 and fits against the top of the workbench 1. The center of the movable plate 102 is fixedly connected to the connecting ring 2. The mounting plate 101 is rotatably connected to the connecting ring 2 through a bearing. The fixing bolt 103 can be rotated to release the fixation between the movable plate 102 and the workbench 1. Rotating the pressing bolt 702 releases the fixation between the connecting rod 7 and the sleeve ring 401 and the pushing ring 501, thereby making it easy to adjust the position of the movable plate 102. This causes the connecting ring 2 to move accordingly, which in turn causes the pressing block 3 to be moved accordingly, thereby adjusting the pressing and fixing position of the pressing block 3. This allows for the adjustment of the distance between the pressing blocks 3 on the outer walls of the two connecting rings 2, thus facilitating the clamping and fixing of cables of different lengths.

[0033] like Figure 4 , Figure 5 As shown, a compression spring 302 is fixedly installed on the side of the compression block 3 near the center of the connecting ring 2. The sliding block 301 is slidably connected to the receiving groove 201 at the center of the connecting ring 2. The outer wall of the end of the compression block 3 away from the connecting ring 2 is inclined towards the center of the connecting ring 2. The compression ring 4 is slidably connected to the compression block 3. When it is necessary to release the fixation, the electric push rod 701 can be easily activated to drive the connecting rod 7 to move, thereby causing the connecting rod 7 to drive the compression ring 4 to move in the opposite direction, and then push the two push rings 501 to move, thereby causing the push rings 501 to drive the sliding plate 5 to move, releasing the engagement between the sliding plate 5 and the side teeth of the sliding block 301, thereby releasing the restriction on the sliding block 301. Under the push of the compression spring 302, the sliding block 301 can move in the opposite direction, thereby releasing the compression block 3 from fixing the cable, thus making it easy to fix and disconnect the cable.

[0034] like Figure 4 , Figure 5 As shown, the sliding plate 5 is slidably connected to the inside of the receiving groove 201 along the horizontal direction. Multiple telescopic springs 502 are provided on the side of the sliding plate 5 away from the sliding block 301, and the two ends of the telescopic springs 502 are fixedly connected to the side wall of the receiving groove 201 and the sliding plate 5, respectively. The top of the sliding plate 5 extends out of the inside of the receiving groove 201 and fits against one side of the push ring 501. Since the teeth on the side of the sliding plate 5 are inclined to the bottom, they can effectively prevent the sliding block 301 from moving in the opposite direction, thereby preventing the pressing block 3 from loosening. At the same time, under the pressure of the pressing ring 4, it can also prevent the pressing block 3 from moving in the opposite direction, thereby maintaining the pressing block 3's tight compression of the cable, keeping it fixed, and facilitating the twisting operation.

[0035] In use, the corresponding cable can be easily threaded through the inside of the two connecting rings 2. Then, the electric push rod 701 is activated, which drives the connecting rod 7 to move. This causes the two sleeve rings 401 to move, thereby causing the compression ring 4 to compress the compression block 3. This causes multiple compression blocks 3 to move towards the center of the connecting ring 2, so that multiple compression blocks 3 can compress and fix the cable at the center of the connecting ring 2. At the same time, the drive assembly 6 is activated, which drives the drive motor 603 to drive the drive gear 602 to rotate. This drives the rotating gear ring 601 to rotate, which causes the connecting ring 2 to rotate. The compression block 3 can drive the cable at one end to rotate, thereby achieving torsion and facilitating testing.

[0036] Simultaneously, as the pressing block 3 moves towards the center of the connecting ring 2, the sliding block 301 moves along with it, thus compressing the pressing spring 302. This causes the teeth on the side of the sliding block 301 to push the sliding plate 5 away. Simultaneously, the sliding plate 5, compressed by the extension spring 502, re-engages with the teeth on the side of the sliding block 301. Since the teeth on the side of the sliding plate 5 are inclined downwards, they effectively prevent the sliding block 301 from moving in the opposite direction, thus preventing the pressing block 3 from loosening. Furthermore, the pressing ring 4 also prevents the pressing block 3 from moving in the opposite direction. This allows the compression block 3 to maintain a tight compression of the cable, keeping it fixed and facilitating twisting operations. When it's necessary to release the cable, the electric push rod 701 can be easily activated to move the connecting rod 7, causing the connecting rod 7 to move the compression ring 4 in the opposite direction. This, in turn, pushes the two push rings 501, causing the push rings 501 to move the sliding plate 5. This releases the engagement between the sliding plate 5 and the teeth on the side of the sliding block 301, thus removing the restriction on the sliding block 301. Under the push of the compression spring 302, the sliding block 301 can move in the opposite direction, releasing the compression block 3 from fixing the cable. This allows for convenient fixing and disconnection of the cable.

[0037] When used with cables of different diameters, the compression ring 4 can easily compress and fix the compression block 3, thus enabling the compression of cables of different diameters. This is suitable for clamping and fixing various cables. When used with cables of different lengths, the fixing bolt 103 can be easily rotated to release the fixation between the moving plate 102 and the worktable 1. Rotating the compression bolt 702 releases the fixation between the connecting rod 7 and the sleeve ring 401 and the pushing ring 501, allowing for easy adjustment of the position of the moving plate 102. This causes the connecting ring 2 to move, which in turn moves the compression block 3, adjusting its clamping and fixing position. This allows for adjustment of the distance between the compression blocks 3 on the outer walls of the two connecting rings 2, facilitating the clamping and fixing of cables of different lengths and simplifying testing.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
