Description

Technical Field

[0001] This utility model relates to the field of capacitor production technology, specifically to a testing fixture for capacitor production. Background Technology

[0002] In the production and testing of capacitors, in order to ensure the stability of the testing process and the accuracy of the test results, it is necessary to use special tooling to reliably fix the capacitor workpiece. Therefore, tooling is an indispensable key auxiliary equipment in the capacitor testing process.

[0003] The prior art patent document CN221352583U provides a clamping fixture for capacitor production, which drives the worm gear to rotate via a self-locking servo motor, and in conjunction with the worm wheel disk transmission, drives the transmission shaft and the rotating wheel to rotate. The rotating wheel pushes the U-shaped rod to move through the transmission rod, thereby completing the clamping operation of the capacitor.

[0004] While the aforementioned existing technology can achieve basic clamping functions, it employs a single-station design, meaning it can only clamp and fix one capacitor workpiece at a time to complete the inspection. After a single workpiece is inspected, it must be removed before a new workpiece to be inspected is re-clamped. During this process, the fixture is idle and waiting. This single-station operation mode reduces the effective utilization rate of the fixture. Therefore, we need an inspection fixture for capacitor production. Summary of the Invention

[0005] The purpose of this invention is to provide a testing fixture for capacitor production, in order to solve the problem of reduced effective utilization of the fixture caused by the single-station operation mode mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a testing fixture for capacitor production, including a frame, wherein a drive assembly is provided on the outer wall of the frame; The drive assembly includes a servo motor, and the output shaft of the servo motor is fixedly connected to a forward threaded rod via a coupling. A first movable frame is threadedly connected to the outer wall of the forward threaded rod, and a first synchronous pulley is fixedly connected to the outer wall of the forward threaded rod. A synchronous belt is provided on the inner wall of the first synchronous pulley. A reverse threaded rod is rotatably connected to the inner wall of the frame, and a second synchronous pulley is fixedly connected to the outer wall of the reverse threaded rod. A second movable frame is threadedly connected to the outer wall of the reverse threaded rod, and an electric push rod is fixedly installed at the bottom of the second movable frame. One end of the electric push rod passes through the second movable frame and is fixedly connected to the top plate. Fixing components are provided on the top of both the top plate and the top of the first movable frame. The fixing component includes a mounting plate, and the outer wall of the mounting plate is provided with fixing bolts. The top of the mounting plate is fixedly connected to a fixing seat, and the inner wall of the fixing seat is provided with a mounting groove. The inner wall of the mounting groove is fixedly connected to a spring, and one end of the spring is fixedly connected to a slider. The outer wall of the slider is fixedly connected to a hemisphere.

[0007] Preferably, the inner wall of the frame is fixedly connected to two limiting rods, and the two limiting rods pass through the first moving frame and the second moving frame respectively. The axes of the two limiting rods are parallel to the axes of the forward threaded rod and the reverse threaded rod respectively, and the outer walls of the limiting rods are in contact with the inner walls of the through holes of the first moving frame and the second moving frame.

[0008] Preferably, a guide rod is fixedly connected to the bottom of the top plate, and one end of the guide rod passes through the second movable frame and is fixed with a limit block. There are four guide rods, and the four guide rods are distributed at the four corners of the top plate. The outer wall of the guide rod is slidably connected to the inner wall of the through hole of the second movable frame, and the diameter of the limit block is larger than the diameter of the guide rod.

[0009] Preferably, the forward threaded rod and the reverse threaded rod are arranged vertically, the first synchronous pulley and the second synchronous pulley form a transmission structure through a synchronous belt, and the shape and size of the first synchronous pulley and the second synchronous pulley are matched.

[0010] Preferably, the fixing base is a hollow cylindrical structure, and there are multiple mounting slots, which are equidistantly arranged in a ring within the fixing base. The mounting slots are circular in shape.

[0011] Preferably, the inner wall shape and size of the mounting groove match the outer wall shape and size of the slider, and the inner wall of the mounting groove fits into the outer wall of the slider, wherein the slider is in the shape of a round block.

[0012] Preferably, the spherical protrusion of the hemisphere protrudes from the mounting groove, and the hemisphere is made of rubber material, with the centers of the multiple hemispheres located on the same circumference.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: Firstly, this utility model establishes a dual-station operation mode by incorporating a drive assembly. When the forward threaded rod is driven to rotate by a servo motor, it moves the first movable frame and the top fixed assembly to the right-side inspection area to meet inspection requirements. Simultaneously, the reverse threaded rod rotates synchronously, moving the second movable frame to the left-side loading and unloading area. The top plate and the top fixed assembly are then moved upward by an electric push rod to complete the replacement and clamping of the workpiece to be inspected. After the workpiece replacement is completed, the top plate is moved downward and reset by the electric push rod. The dual-station switching can be achieved by reversing the operation of the servo motor. Throughout the process, the inspection operation and the workpiece clamping operation can be carried out simultaneously, eliminating the idle waiting time during workpiece disassembly and assembly in traditional single-station tooling, effectively improving tooling utilization and shortening the cycle of a single inspection operation.

[0014] Secondly, when clamping a workpiece, this utility model loads the capacitor workpiece into the fixed base, squeezes multiple hemispheres, and causes the slider to compress the spring. Utilizing the elastic restoring force of the spring, the multiple hemispheres can clamp the capacitor workpiece, achieving rapid clamping. The entire clamping and loading / unloading process does not require complex operation steps, reducing the intensity and difficulty of manual operation and improving the efficiency of workpiece replacement.

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.

[0018] like Figure 1-4 As shown, a testing fixture for capacitor production includes a frame 1, and a drive assembly 2 is provided on the outer wall of the frame 1. The drive assembly 2 includes a servo motor 201, and the output shaft of the servo motor 201 is fixedly connected to a forward threaded rod 202 via a coupling. The outer wall of the forward threaded rod 202 is threadedly connected to a first moving frame 203, and the outer wall of the forward threaded rod 202 is fixedly connected to a first synchronous pulley 204. The inner wall of the first synchronous pulley 204 is provided with a synchronous belt 205. The inner wall of the frame 1 is rotatably connected to a reverse threaded rod 206, and the outer wall of the reverse threaded rod 206 is fixedly connected to a second synchronous pulley 207. The outer wall of the reverse threaded rod 206 is threadedly connected to a second moving frame 208, and an electric push rod 209 is fixedly installed at the bottom of the second moving frame 208. One end of the electric push rod 209 passes through the second moving frame 208 and is fixedly connected to the top plate 210. The top of the top plate 210 and the top of the first moving frame 203 are both provided with a fixing assembly 3. The fixing component 3 includes a mounting plate 301, and the outer wall of the mounting plate 301 is provided with fixing bolts 302. The top of the mounting plate 301 is fixedly connected to a fixing seat 303, and the inner wall of the fixing seat 303 is provided with a mounting groove 304. The inner wall of the mounting groove 304 is fixedly connected to a spring 305, and one end of the spring 305 is fixedly connected to a slider 306. The outer wall of the slider 306 is fixedly connected to a hemispherical ball 307.

[0019] Through the above technical solution, a controller is installed on the frame 1 to control the operation of the device; the servo motor 201 is fixedly installed on the frame 1; the servo motor 201 drives the forward threaded rod 202 to rotate, which drives the first moving frame 203 to move, and at the same time drives the reverse threaded rod 206 to rotate through the first synchronous pulley 204, the synchronous belt 205, and the second synchronous pulley 207, which causes the second moving frame 208 to move in the opposite direction, thereby realizing the alternating movement of the two moving frames and realizing the switching of the workstation; at the same time, the distance between the first moving frame 203 and the second moving frame 208 is reserved to facilitate the passage of the clamped capacitor workpiece.

[0020] Specifically, two limiting rods are fixedly connected to the inner wall of the frame 1, and the two limiting rods pass through the first moving frame 203 and the second moving frame 208 respectively. The axes of the two limiting rods are parallel to the axes of the forward threaded rod 202 and the reverse threaded rod 206 respectively, and the outer walls of the limiting rods are in contact with the inner walls of the through holes of the first moving frame 203 and the second moving frame 208.

[0021] Through the above technical solution, the limiting rod can restrict the movement direction of the first moving frame 203 and the second moving frame 208, prevent them from rotating under the drive of the threaded rod, ensure that the two moving frames can move stably in a straight line, and improve the stability of the tooling operation.

[0022] Specifically, a guide rod 211 is fixedly connected to the bottom of the top plate 210, and one end of the guide rod 211 passes through the second movable frame 208 and is fixed with a limit block. There are four guide rods 211, and the four guide rods 211 are distributed at the four corners of the top plate 210. The outer wall of the guide rod 211 is slidably connected to the inner wall of the through hole of the second movable frame 208, and the diameter of the limit block is larger than the diameter of the guide rod 211.

[0023] Through the above technical solution, the guide rod 211 can play a guiding role when the electric push rod 209 drives the top plate 210 to move up and down, ensuring that the movement of the top plate 210 is more stable and avoiding tilting; the four guide rods 211 are distributed at the four corners, which further improves the stability of the guide, while the limiting block can prevent the guide rod 211 from disengaging from the second moving frame 208. At the same time, when the limiting block contacts the bottom of the second moving frame 208, it makes the top plate 210 drive the fixed seat 303 to be on the same horizontal line as the fixed seat 303 on the first moving frame 203, which is convenient for use.

[0024] Specifically, the forward threaded rod 202 and the reverse threaded rod 206 are arranged vertically, and the first synchronous pulley 204 and the second synchronous pulley 207 form a transmission structure through the synchronous belt 205, and the shape and size of the first synchronous pulley 204 and the second synchronous pulley 207 are matched with each other.

[0025] With the above technical solution, the forward threaded rod 202 and the reverse threaded rod 206 are arranged vertically to ensure that the two moving frames do not interfere with each other when moving. Through the cooperation of the first synchronous pulley 204, the synchronous belt 205 and the second synchronous pulley 207, it can be ensured that the forward threaded rod 202 and the reverse threaded rod 206 rotate synchronously. Since the threads of the two are opposite, the second moving frame 208 can move to the right when the first moving frame 203 moves to the left, thus ensuring the coordination of the alternating movement of the two workstations.

[0026] Specifically, the fixing base 303 is a hollow cylindrical structure, and there are multiple mounting slots 304. The multiple mounting slots 304 are equidistantly and annularly arranged in the fixing base 303, and the shape of the mounting slots 304 is a circular groove.

[0027] Through the above technical solution, the hollow cylindrical mounting base 303 is adapted to the shape of the capacitor, making it easy to place the capacitor; multiple equally spaced annular mounting slots 304 can install multiple springs 305 and sliders 306 assemblies, which can fix the capacitor from multiple directions, making the fixing effect more uniform and stable, and can fix workpieces with small changes in capacitor diameter; when the capacitor diameter changes significantly, the mounting plate 301 can be disassembled and replaced with a matching fixing component 3, reducing the cost of replacement.

[0028] Specifically, the inner wall shape and size of the mounting groove 304 match the outer wall shape and size of the slider 306, and the inner wall of the mounting groove 304 fits into the outer wall of the slider 306, which is a circular block.

[0029] Through the above technical solution, the shape and size of the mounting groove 304 and the slider 306 are matched and fit together, which can guide and limit the movement of the slider 306, ensuring that the slider 306 can only move along the axial direction of the mounting groove 304, and preventing the slider 306 from deviating or getting stuck during the movement.

[0030] Specifically, the spherical protrusion of the hemisphere 307 protrudes from the mounting groove 304, and the hemisphere 307 is made of rubber material, with the centers of multiple hemispheres 307 located on the same circumference.

[0031] Through the above technical solution, the spherical protrusion of the hemisphere 307 is exposed in the mounting groove 304, which facilitates contact with the outer wall of the capacitor. The rubber material has a certain elasticity and friction, which can clamp the capacitor by the force of the spring 305 and avoid damage to the outer wall of the capacitor. The centers of the multiple hemispheres 307 are located on the same circumference, which can make the capacitor receive a uniform clamping force and ensure that it is stably fixed in the center position of the fixing seat 303.

[0032] In use, first connect an external power supply to the device. The external power supply provides power to the device. By starting the servo motor 201, the forward threaded rod 202 is driven to rotate. The first moving frame 203 moves to the right along a straight line under the guidance of the limit rod to the detection station. At the same time, the rotation of the forward threaded rod 202 drives the first synchronous pulley 204 to rotate. The first synchronous pulley 204 drives the second synchronous pulley 207 to rotate via the synchronous belt 205. The second synchronous pulley 207 drives the reverse threaded rod 206 to rotate synchronously, so that the second moving frame 203... 8. Move left to the loading / unloading station. After the two moving frames move to the station, the servo motor 201 stops working. At the loading / unloading station, the electric push rod 209 works to push the top plate 210 upward. The top plate 210 drives the four guide rods 211 to move more stably. The top plate 210 drives the mounting plate 301 and the fixed seat 303 to move upward to the designated position. The operator puts the capacitor workpiece to be tested into the fixed seat 303. The capacitor workpiece squeezes the rubber hemisphere 307 on the inner wall of the fixed seat 303, which drives the slider 306 to compress the spring. Spring 305, with its reverse elastic force, causes the rubber hemisphere 307 to clamp the capacitor workpiece from multiple directions, fixing it at the center of the fixed base 303 to prevent displacement during subsequent movement or testing. Once fixed, the electric push rod 209 operates, driving the top plate 210 to move down and reset. After the right-side testing station completes its testing, the servo motor 201 operates, causing the first moving frame 203 to move to the left, moving the tested capacitor workpiece to the loading / unloading station. The second moving frame 208 moves the capacitor workpiece to be tested to the right, and the electric push rod 209 operates, pushing the top plate 210 upward, causing the fixed base 303 containing the capacitor workpiece to be tested to move to the testing station. At this time, the operator can perform unloading and loading operations on the capacitor workpiece on the first moving frame 203. Throughout the process, the testing operation and the workpiece clamping operation can be carried out simultaneously, effectively improving the tooling utilization rate and shortening the cycle of a single testing operation. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
