Description

Technical Field

[0001] This invention relates to the field of spring bushing positioning technology, specifically a positioning clamp that can be adapted to various spring bushings. Background Technology

[0002] With the rapid development of the machinery and equipment manufacturing industry, spring bushings, as key basic components in transmission, shock absorption and connection structures, have seen a continuous increase in application scenarios and demand. In the processing and production of spring bushings, positioning fixtures are the core tooling to ensure the precision of their shape processing and hole diameter machining. The adaptability and positioning accuracy of the fixtures directly determine the processing qualification rate of the finished spring bushings. Therefore, special positioning fixtures that can adapt to various spring bushings are needed to complete the clamping and positioning operations of spring bushings of different specifications.

[0003] However, existing positioning fixtures mostly have a single clamping method, making it difficult to adapt to spring bushings of various shapes and sizes. They have poor versatility and insufficient constraint on the workpiece during clamping, which can easily cause the spring bushing to shift position during processing, affecting the overall fixation stability. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning fixture that can be adapted to various spring bushings. By setting a fixing part, it solves the problems of existing positioning fixtures, which mostly have a single clamping method, are difficult to adapt to spring bushings of various shapes and sizes, have poor versatility, and have insufficient limiting constraints on the workpiece during clamping, which can easily cause the spring bushing to shift position during processing and affect the overall fixing stability.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a positioning clamp adaptable to various spring bushings, comprising a base, and further comprising: two fixing parts, both of which are mounted on the base; a power unit mounted on the base; each fixing part including a drive assembly mounted on the base; a transmission assembly mounted on the drive assembly; and a fixing assembly mounted on the top of the base; the drive assembly including a rectangular plate mounted on the top of the base, with a hollow shaft passing through the rectangular plate, the hollow shaft being rotatably connected to the rectangular plate. A cross bracket is fixedly connected to the outer wall of the rectangular plate. A cylindrical rod passes through the cross bracket and is slidably connected to the cross bracket. A threaded groove is formed on the outer wall of the cylindrical rod, and a transmission block is provided in the threaded groove. The transmission block is fixedly connected to the inner wall of the hollow shaft. An elastic element is provided on the cylindrical rod. The two fixed parts are mirror images of each other. The cylindrical rod is located inside the hollow shaft. The elastic element includes a spring sleeved on the outer wall of the cylindrical rod. The side of the spring closer to the fixed plate is fixedly connected to the fixed plate, and the side of the spring away from the fixed plate is fixedly connected to the cross bracket.

[0006] Furthermore, the power unit includes a limiting component mounted on the base; a power component disposed on the base; and the power component located below the base.

[0007] Furthermore, the transmission assembly includes a circular plate fixedly connected to the outer wall of the hollow shaft. The circular plate has several arc-shaped grooves, and the cross bracket has several sliding grooves. Rectangular rods are slidably connected to each of the sliding grooves, and transmission components are disposed within each of the arc-shaped grooves. There are four arc-shaped grooves and four sliding grooves arranged in a circumferential array. The transmission components include transmission rods respectively disposed within the arc-shaped grooves, and the transmission rods are fixedly connected to the rectangular rods respectively. There are four transmission rods.

[0008] Furthermore, the fixing assembly includes a fixing plate fixedly connected to the side of the cylindrical rod away from the hollow shaft. An anti-slip through-pad is fixedly connected to the side of the fixing plate away from the hollow shaft. Rectangular grooves are formed on each of the rectangular rods. Rectangular limiting plates are slidably connected within each of the rectangular grooves. L-shaped rods are fixedly connected to each of the rectangular limiting plates. The sides of the L-shaped rods away from the rectangular limiting plates extend beyond the rectangular rods. The rectangular limiting plates are slidably connected to the rectangular rods. A number of sliding rods are fixedly connected to the outer wall of the fixing plate. The sides of the sliding rods away from each other extend beyond the rectangular rods. In addition to several L-shaped rods, several L-shaped rods are slidably connected to several sliding rods, and several L-shaped rods are provided with fixing components; four sliding rods are provided and arranged in a circumferential array, and the fixing components include spring damping rods respectively provided in several rectangular grooves, the side of several spring damping rods near several rectangular limiting plates is fixedly connected to several rectangular limiting plates, the side of several spring damping rods away from several rectangular limiting plates is fixedly connected to several rectangular rods, and the side of several L-shaped rods that are close to each other is fixedly connected with an arc-shaped fixing plate; the material of the side of the four arc-shaped fixing plates that are close to each other is silicone.

[0009] Furthermore, the limiting component includes a limiting groove formed on the top of the base, and two sliders are slidably connected in the limiting groove. The tops of the two sliders are respectively fixedly connected to two rectangular plates; the two sliders are mirror images of each other.

[0010] Furthermore, the power assembly includes two support plates fixedly connected to the inner wall of the top of the base. A bidirectional threaded rod is rotatably connected between the two support plates. The right side of the bidirectional threaded rod passes through the support plate located on the right side and passes through two sliders. The bidirectional threaded rod is threadedly connected to the two sliders. A motor is fixedly connected to the right side of the support plate located on the right side. The output shaft of the motor is fixedly connected to the bidirectional threaded rod through a coupling. A protective component is provided on the bidirectional threaded rod. The two sliders are respectively located on the threads on both sides of the bidirectional threaded rod. The protective component includes several telescopic protective sleeves sleeved on the outer wall of the bidirectional threaded rod. The two telescopic protective sleeves located on the left and right sides, with their sides close to each other, are fixedly connected to the two sliders respectively. The two telescopic protective sleeves located on the left and right sides, with their sides far from each other, are fixedly connected to the two support plates respectively. Three telescopic protective sleeves are provided, and the two sides of the telescopic protective sleeve located in the middle are fixedly connected to the two sliders respectively.

[0011] The present invention has the following beneficial effects: (1) By setting a fixing part, when the rectangular plates approach each other, the cylindrical rod is pushed against the anti-slip through pad and the surface of the spring bushing by the linkage of the cross bracket and the spring. The rectangular plates move continuously and drive the hollow shaft to rotate through the threaded groove and the transmission block. The hollow shaft drives the circular plate to rotate. Then, through the transmission cooperation of the arc groove and the slide groove, the transmission rod and the rectangular rod are pushed to move synchronously. The rectangular rod drives the L-shaped rod to slide smoothly along the slide rod in sequence. Finally, multiple sets of arc-shaped fixing plates surround from the outside and cooperate with the anti-slip through pad to form a wrap-around clamping and fixing of the spring bushing. The multi-directional surround-around clamping method is suitable for spring bushings of various shapes and sizes, avoids the spring bushing from shifting during processing, and improves the stability of fixing. (2) By setting a fixing component, when the two rectangular plates move towards each other, the cylindrical rod is driven to approach the spring bushing through the linkage of the cross bracket and the spring, so that the anti-slip through pad on the fixing plate fits the bushing; the rectangular plates continue to move closer, causing the hollow shaft and the cross bracket to slide along the cylindrical rod. The cross bracket pulls the rectangular rod to move through the slide groove and cooperates with the slide rod. The rectangular rod slides along the rectangular limiting plate and the L-shaped rod and squeezes the spring damping rod. Relying on the elastic force generated by the deformation of the spring damping rod, the four arc-shaped fixing plates are kept in their original positions. During the clamping and adjustment of the rectangular plates, the mechanical linkage and the buffer limiting effect of the spring damping can keep the arc-shaped fixing plates in their original positions without shifting. (3) By setting up a power unit, the spring bushing is placed between two fixed plates during use. The motor drives the bidirectional threaded rod to rotate. With the cooperation of the bidirectional threaded rod and the limiting slide groove, the two sliders slide towards each other along the limiting slide groove. During the movement of the sliders, the telescopic protective sleeve deforms to protect the thread groove of the threaded rod. At the same time, the slider and the rectangular plate move closer together to achieve the clamping and positioning of the workpiece. This enables the rapid centering and clamping of spring bushings of various specifications. The clamping and adjustment are smooth and stable. The telescopic protective sleeve can effectively protect the thread structure of the bidirectional threaded rod, prevent foreign objects from entering and causing wear and jamming, extend the service life of the fixture, and improve the efficiency of workpiece processing.

[0019] By setting the fixing component 23, the arc-shaped fixing plate 238 can always remain in its original position without shifting during the clamping and adjustment of the rectangular plate 211, relying on the buffering and limiting effect of mechanical linkage and spring damping.

[0020] The power unit 3 includes a limiting component 31, which is mounted on the base 111; and a power component 32, which is also mounted on the base 111 and located below the base 111. The limiting component 31 includes a limiting groove 311 formed on the top of the base 111, in which two sliders 312 are slidably connected. The tops of the two sliders 312 are fixedly connected to two rectangular plates 211, respectively. The two sliders 312 are mirror images of each other. The power component 32 includes two support plates 321 fixedly connected to the inner wall of the top of the base 111. A bidirectional threaded rod 322 is rotatably connected between the two support plates 321. The right side of the bidirectional threaded rod 322 passes through the support plate 321 on the right side and through the two sliders 312. The bidirectional threaded rod 322 is threadedly connected to the two sliders 312. A motor 323 is fixedly connected to the right side of the support plate 321 on the right side, and the output shaft of the motor 323 is connected via a coupling. The device is fixedly connected to the bidirectional threaded rod 322, which is equipped with protective components. Two sliders 312 are located on the threads on both sides of the bidirectional threaded rod 322. The protective components include several telescopic protective sleeves 324 sleeved on the outer wall of the bidirectional threaded rod 322. The two telescopic protective sleeves 324 located on the left and right sides are fixedly connected to the two sliders 312 on the side closer to each other, and the two telescopic protective sleeves 324 located on the left and right sides are fixedly connected to the two support plates 321 on the side farther from each other. There are three telescopic protective sleeves 324, and the two sides of the telescopic protective sleeve 324 located in the middle are fixedly connected to the two sliders 312. By setting the power unit 3, the quick centering and clamping positioning of spring bushings of various specifications can be realized, and the clamping adjustment is smooth and stable. The telescopic protective sleeves 324 can effectively protect the thread structure of the bidirectional threaded rod 322, prevent foreign objects from entering and causing wear and jamming, extend the service life of the fixture, and improve the efficiency of workpiece processing.

[0021] It should be noted that the motor 323 in this application can be automatically controlled by using a program set in the control panel and inputting relevant parameters as needed. This control method can be achieved using existing technologies, such as PLC.

[0022] In use, the spring bushing to be processed is placed between two fixed plates 231, and the motor 323 is started. The motor 323 drives the bidirectional threaded rod 322 to rotate. Under the action of the bidirectional threaded rod 322 and the limiting slide groove 311 in parallel cooperation, the bidirectional threaded rod 322 drives the two sliders 312 to slide in the limiting slide groove 311 and move closer to each other. At this time, the three telescopic protective sleeves 324 deform with the movement of the two sliders 312, thereby protecting the threaded groove on the bidirectional threaded rod 322. The two sliders 312 respectively drive the two rectangular plates 211 to move closer to each other. When the two rectangular plates 211 approach each other, the rectangular plates 211 drive the cylindrical rod 214 to approach the spring bushing to be processed through the cross bracket 213 and the spring 217. The cylindrical rod 214 drives the anti-slip through pad 232 on the fixed plate 231 to contact the spring bushing to be processed. At this time, the two rectangular plates 211 continue to approach each other, and the rectangular plates 211 drive the hollow shaft 212 and the cross bracket 213 to slide on the cylindrical rod 214. At this time, the cross bracket 213 drives the rectangular rod 224 to move through the slide groove 223 and cooperates with the slide rod 236. The rectangular rod 224 slides on the rectangular limiting plate 234 and the L-shaped rod 235 and squeezes the spring damping rod 237, causing the four spring damping rods 237 to deform and generate elastic force, keeping the position of the four arc-shaped fixed plates 238 on the four L-shaped rods 235 unchanged. During the movement of the hollow shaft 212 driven by the rectangular plate 211, the hollow shaft 212 rotates on the rectangular plate 211 under the cooperation of the threaded groove 215 and the transmission block 216. The hollow shaft 212 drives the circular plate 221 to rotate. Under the cooperation of the four arc grooves 222 and the four sliding grooves 223, the circular plate 221 pushes the transmission rod 225 to move through the arc grooves 222. The transmission rod 225 drives the rectangular rod 224 to slide in the sliding groove 223 and makes the four rectangular rods 224 approach each other. The four rectangular rods 224 drive the four L-shaped rods 235 to move through the four rectangular limiting plates 234 respectively. Since the four sliding rods 236 are slidably connected to the four L-shaped rods 235 respectively, it ensures that the four L-shaped rods 235 approach each other smoothly. The L-shaped rods 235 drive the four arc-shaped fixing plates 238 to approach the outer wall of the spring bushing to be processed, thereby fixing them to the left and right sides of the two anti-slip through pads 232, thus wrapping and fixing the spring bushing to be processed. After fixing, the outer wall of the spring bushing to be processed is processed using processing equipment.
