It is commonly used in engines or devices with high mechanical performance. Crank machining refers to the process of machining a crank blank through multiple steps to finally produce a crankshaft with a certain precision and quality.

[0003] After the crank is manufactured, its surface temperature is high. With current technology, workers need to use pliers to clamp and handle the crank for extended periods. During this process, the high temperature of the crank can cause burns or other injuries to workers, posing a significant safety hazard. Furthermore, using pliers to handle the crank makes it difficult to ensure that the position and angle are consistently accurate each time, which may affect the quality and precision of subsequent processing.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a crank positioning and clamping device, including a worktable 1; it also includes a clamping assembly and an adjusting component.

A connecting seat 2 is rotatably mounted on the worktable 1. A balancing component is provided to the right of the connecting seat 2. An adjusting component is provided on the left side of the worktable 1. The adjusting component is equipped with a second servo motor 205 for subsequent clamping and flipping. The driving component is also equipped with an electric cylinder 302 for subsequent up-and-down movement. A clamping assembly is provided at the upper end of the electric cylinder 302. The clamping assembly includes a placement block 4, a sliding block 402, and... The clamping cylinder 403 and the sliding block 402 are slidably set on the placement block 4 and fastened by threads. There are two sliding blocks 402 slidably set on the placement block 4. The upper end of the sliding block 402 is provided with two clamping cylinders 403 for clamping the inner rings at both ends of the crank. During use, the worker only needs to use pliers to slightly adjust the sliding position of the crank at the unloading box 105. The upper clamping cylinder 403 of the clamping positioning device clamps the crank through groove. Then, the adjusting component drives the clamped crank to rotate and rotate horizontally to carry out subsequent processing steps. This solves the problem that the surface temperature of the crank is high after it is made, and the worker may cause safety hazards by using pliers to clamp and transport it for a long time.

[0025] Please see Figures 1-3 In this embodiment, a bearing seat 103 is provided on the worktable 1, and a first servo motor 104 is provided at the lower end of the worktable 1. The output shaft of the first servo motor 104 passes through the bearing seat 103 and is connected to a connecting seat 2. The bearing seat 103 can improve the stability of the first servo motor 104. Four support legs 101 are fixedly connected to the lower end of the worktable 1. A control box 102 for control and scheduling is also provided on the worktable 1. The balancing component includes a counterweight frame 202 and a counterweight block 203. The counterweight frame 202 is fixedly connected to the right end of the connecting seat 2. The counterweight block 203 for balancing the left side of the connecting seat 2 is placed on the counterweight frame 202. The counterweight frame 202 is fixedly connected to the right end of the connecting seat 2 and the counterweight block is placed thereon. 203 enables the connecting seat 2 to maintain balance during rotation and other operations, reducing swaying and offset caused by uneven weight distribution, improving the stability and reliability of the device operation, and ensuring that the processing steps such as clamping, positioning, flipping, and horizontal rotation of the crank can be carried out accurately and smoothly. A placement groove 201 is provided above the connecting seat 2. A fixing plate 204 is fixed to the left side of the inner wall of the placement groove 201. A second servo motor 205 is provided at the right end of the fixing plate 204. A coupling 206 is provided on the outer wall after the output shaft of the second servo motor 205 passes through the fixing plate 204. An L-shaped connecting plate 3 is fixed to the left end of the coupling 206. The second servo motor 205 drives the clamping parts on the device to rotate.

[0026] Please see Figures 4-6 In this embodiment, two L-shaped connecting plates 3 are provided. The front and rear ends of the two L-shaped connecting plates 3 are connected by a connecting bracket 301. An electric cylinder 302 is provided at the lower end of the L-shaped connecting plate 3. The telescopic rod of the electric cylinder 302 passes through the L-shaped connecting plate 3 and is connected to a connecting plate 303. The upper ends of the placement block 4 and the two connecting plates 303 are connected to each other. A four-way groove 401 is provided on the placement block 4. The sliding block 402 is slidably disposed in the four-way groove 401. Limiting sliding grooves 404 are also provided at the front and rear ends of the placement block 4. An extension block 405 is fixedly connected to the lower end of the sliding block 402. Two threaded grooves 406 are provided at the front and rear ends of the extension block 405. The threaded grooves 406 are threaded inside. The sliding block 402 is connected by a threaded rod 407, on which a friction ring 408 is provided. By rotating the threaded rod 407, the threaded rod 407 rotates into the four-way groove 401, thereby squeezing the friction ring 408 and increasing the friction force of the friction ring 408 on the placement block 4. Thus, the position of the sliding block 402 is fixed by multiple friction rings 408. The friction ring 408 is located in the limiting sliding groove 404. The ends of the two extension blocks 405 on the sliding block 402 that are far apart from each other are in contact with the front and rear ends of the inner wall of the four-way groove 401. The front and rear ends of the placement block 4 are in contact with the ends of the connecting bracket 301 connected to the front and rear ends of the L-shaped connecting plate 3 that are close to each other.

[0027] In use, first adjust the position of the sliding blocks 402 on the two placement blocks 4. By rotating the threaded rod 407, the friction ring 408 loosens its clamping grip on the placement block 4. Then, adjust the distance between the two sliding blocks 402 by referring to the distance between the two through grooves of the crank that needs to be clamped and positioned. After adjustment, the four threaded rods 407 below the sliding blocks 402 can be quickly tightened using an electric screwdriver. Then, place the corresponding weight counterweight 203 on the counterweight frame 202 for fixation. Next, move the device to the processing and unloading area, aligning the unloading box 105 with the crank processing part unloading groove 106. Slide the crank with higher temperature onto the unloading box 105. Then, the worker uses pliers to make fine adjustments so that the two through grooves of the crank are positioned at the center of the two clamping cylinders 403 on the two sliding blocks 402. Then, by activating the electric cylinder 302, the two electric cylinders 302 move... The movable placement block 4 moves upward, causing the two clamping cylinders 403 on the sliding block 402 to expand and clamp the two through slots on the crank respectively. Then, by turning on the first servo motor 104, the output shaft of the first servo motor 104 drives the connecting seat 2 to rotate, thereby sliding and clamping the crank out of the feeding slot 106 on the feeding box 105. Then, it is clamped by the connecting seat 2 and placed in the subsequent processing area. During processing, the second servo motor 205 can be turned on to rotate the L-shaped connecting plate 3 as a whole, thereby performing rotation angle processing on the crank clamped by the clamping cylinder 403. After processing, the second servo motor 205 drives the L-shaped connecting plate 3 to rotate, bringing the crank closer to the conveying device. Then, the clamping cylinder 403 is released, the clamping is canceled, and then the reset operation is performed. The two clamping cylinders 403 on the sliding block 402 share a common air pump to ensure that the clamping work can be performed synchronously.
