Description

Technical Field

[0001] This utility model relates to the field of chain production technology, and in particular to a stretching and calibration device for chain production. Background Technology

[0002] In fields such as mechanical transmission and conveying, the quality of chains directly affects the stability and reliability of equipment operation. During the chain production process, the stretching and calibration process applies tension to the chain to correct the chain pitch and eliminate internal stress, ensuring that the chain meets the precision standards. With the improvement of industrial automation, the market's requirements for the precision, strength and consistency of chains are constantly increasing.

[0003] Traditional stretching calibration devices are mostly designed with fixed stretching parameters and are only suitable for the production of chains of a single specification. When it is necessary to switch to producing chains with different pitches and materials, the lack of stretching adjustment function makes it impossible to adjust the tension and stretching stroke, making it difficult to control the stretching amount of lightweight chains, which leads to a significant reduction in the stretching calibration quality of the device.

[0004] Therefore, it is necessary to provide a tensioning and calibration device for chain production to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a stretching and calibration device for chain production, which solves the problem that traditional devices can only stretch and calibrate chains of a single size.

[0009] Preferably, a locking block is fixedly connected to the inner cover, the locking block has a locking groove that can cooperate with the telescopic block, and a lifting restriction block for easy lifting is installed on the inner cover.

[0010] Preferably, the support module includes a device support rod installed at the bottom of the device base plate, and the bottom of the device support rod is equipped with an anti-slip component for preventing slippage.

[0011] Preferably, a vertical fixing plate for supporting the transverse tension column is fixedly connected to the base plate of the device, and the first connecting rod and the second connecting rod are connected to the limiting round head for rotation via a vertical shaft.

[0014] This invention provides a stretching and calibration device for chain production. When using this device, the drive unit can be started by controlling the controller.

Figure 3 for Figure 1 The diagram shows the outer casing structure. Figure 4 for Figure 1 The diagram shows a left-side sectional view of a transversely stretched column. Figure 5 for Figure 4 The diagram shows a front view of a transverse tension column section. Figure 6for Figure 4 The enlarged schematic diagram of part A shown below; Figure 7 for Figure 2 The enlarged schematic diagram of part B is shown. A chain production stretching and calibration device includes: a device body 1, the device body 1 including a device base plate 7, a protection module 4, a support module 6, and a stretching module 2.

A vertical shaft 207 for connection is provided at the bottom of the limiting round head 204. A first connecting rod 210 and a second connecting rod 211 are provided on the vertical shaft 207. A device fixing block 205 is provided on the transverse stretching column 203. An adjusting limiting block 209 is installed on the stretching module 2.

[0025] The driving component 201 can be a motor, pneumatic motor, hydraulic motor, or other driving device that can drive the transverse slide bar 206 to rotate. Of the aforementioned limiting round head 204, only the middle one is fixedly installed on the transverse tension column 203, while the middle one and the limiting round heads 204 on both sides are movable. One of the limiting round heads 204 on the threaded rod 208 has a threaded groove that can cooperate with the threaded rod 208. The first connecting rod 210 and the second connecting rod 211 are rotatably connected by the vertical shaft 207.

The outer cover 405 has an inner cover groove 408, and an inner cover 406 is provided on the inner cover groove 408. The inner cover 406 is provided with an inner cover limiting block 407 to prevent it from falling off. The inner cover 406 and the outer cover 405 work together to prevent injury to the operator due to chain breakage, thereby protecting the operator.

[0027] The protection module 4 includes a slot 401 formed on the device base plate 7. A locking block 410 is fixedly connected inside the slot 401. A telescopic limiting plate 413 is slidably connected to the slot 401. A telescopic rod 412 is fixedly connected to the telescopic limiting plate 413. A telescopic block 409 is fixedly connected to the upper end of the telescopic rod 412. An elastic element 411 for assisting the telescopic block 409 in resetting is provided on the telescopic rod 412.

[0028] The elastic element 411 can be an elastic component with elastic effect, such as a spring or elastic sponge. When the operator releases the telescopic rod 412, the elastic element 411 can use its own elastic force to push the telescopic block 409 to reset.

The limiting round head 204 can assist the chain in stretching when the chain is stretched and calibrated.

[0034] The device base plate 7 is equipped with a controller 5 for controlling the operation of the device. The controller 5 can control the operation of the drive component 210 in real time.

[0035] The working principle of the tensioning and calibration device for chain production provided by this utility model is as follows:

[0036] When using this device, the drive unit 201 can be started by controlling the controller 5. At this time, the drive unit 201 can drive the transverse slide bar 206 to rotate. At the same time, the transverse slide bar 206 will drive the threaded rod 208 to rotate. At this time, the threaded rod 208 will drive the end limiting round head 204 to move along the threaded rod 208. At the same time, the end limiting round head 204 will drive the vertical shaft 207 to move laterally. At this time, the vertical shaft 207 will drive the first connecting rod 210 and the second connecting rod 211 to rotate around the vertical shaft 207. As the end limiting round head 204 moves, it will drive other limiting round heads 204 to slide along the transverse slide groove 202.

[0037] Compared with related technologies, the tensioning and calibration device for chain production provided by this utility model has the following beneficial effects:

[0038] When using this device, the drive unit 201 can be started by controlling the controller 5. At this time, the drive unit 201 can drive the threaded rod 208 to rotate. The threaded rod 208 will drive the limiting round head 204 at the end to move along the threaded rod 208. At the same time, the vertical shaft 207 will drive the first connecting rod 210 and the second connecting rod 211 to rotate around the vertical shaft 207, thereby driving the limiting round head 204 to slide inside the transverse slide groove 202. This device adds an adjustment function for the tensioning device. Through the tension adjustment function, the tension of the chain can be adjusted according to different chain specifications and production requirements. The chain can be moderately stretched to make the force between the chain links more uniform, thereby enhancing the strength uniformity of the entire chain, reducing the risk of local fatigue fracture during chain use, and thus improving the chain straightening quality.
