Description

Technical Field

[0001] This utility model belongs to the field of boiler parts manufacturing technology, specifically relating to a clamping device for boiler parts manufacturing. Background Technology

[0002] In the boiler manufacturing industry, the machining accuracy of boiler parts directly affects the overall performance of the boiler, and the stability and applicability of clamping devices, as key tooling for part machining, are of paramount importance.

[0003] In existing technologies, conventional boiler accessory clamping devices mostly employ a single clamping plate structure or a simple symmetrical clamping method, using bolts or hydraulic drive to fix the accessories. However, these devices exhibit significant drawbacks in practical applications: firstly, a single clamping structure struggles to generate a balanced clamping force when dealing with accessories of different diameters, easily leading to accessory shifting or wobbling during processing, affecting processing accuracy and even causing safety accidents; secondly, the adjustment mechanism of traditional devices often only allows for linear adjustment of the clamping plate spacing, failing to adapt to the curved surface fitting requirements of accessories of different diameters. Especially for cylindrical boiler accessories, the planar clamping method of conventional clamping plates easily results in insufficient contact area and poor clamping stability. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for the production of boiler accessories, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping device for boiler parts production, comprising a base and a clamping mechanism, wherein the clamping mechanism comprises a hydraulic cylinder fixedly installed on both sides of the base and a main clamping plate fixedly connected to the piston end of the hydraulic cylinder, wherein two symmetrically distributed auxiliary clamping plates are hinged to the side of the two main clamping plates that are close to each other, and a driving component for driving the auxiliary clamping plates to rotate is provided inside the main clamping plate.

[0006] In a preferred embodiment, the top of the base is provided with a sliding groove, and the bottom of the main clamping plate is fixedly connected to a slider, which is slidably connected in the sliding groove.

[0007] In a preferred embodiment, the driving component includes a bidirectional screw rotatably mounted in the main clamping plate, with two symmetrically distributed connecting blocks threaded onto the bidirectional screw, and a connecting rod hinged between the connecting blocks and the auxiliary clamping plate.

[0008] In a preferred embodiment, the bidirectional screw is arranged horizontally along the length of the main clamping plate.

[0009] In one preferred embodiment, a motor is fixedly mounted on one end of the main clamping plate.

[0010] In a preferred embodiment, the main clamping plate has a strip-shaped sliding hole on the side near the auxiliary clamping plate, and the connecting block is slidably connected in the strip-shaped sliding hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This clamping device for boiler parts production, through the setting of the clamping mechanism, first places the end face of the boiler part on the base when clamping the boiler part. Then, two hydraulic cylinders are activated to drive two main clamping plates to move closer to each other, so that the main clamping plates abut against the outer walls of both sides of the boiler part for initial clamping. Then, the drive unit is activated to drive two auxiliary clamping plates on the same main clamping plate to rotate in opposite directions, so that the four auxiliary clamping plates abut against the outer walls of the boiler part, and cooperate with the main clamping plates to provide auxiliary clamping of the boiler part, so that the boiler part is subjected to force at multiple points, improving the clamping effect and stability.

[0013] This clamping device for boiler parts production, through the setting of the driving component, can start the motor to drive the bidirectional screw to rotate when using the auxiliary clamping plate. The bidirectional screw drives the two connecting blocks to slide in opposite directions along the strip-shaped sliding hole. The connecting blocks drive the two auxiliary clamping plates to rotate synchronously through the connecting rod, thereby adjusting the included angle of the two auxiliary clamping plates, which is convenient for clamping boiler parts of different diameters.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figure 1-3 This utility model provides a clamping device for boiler parts production, including a base 1 and a clamping mechanism 2. The clamping mechanism 2 includes hydraulic cylinders 21 fixedly installed on both sides of the base 1 and main clamping plates 22 fixedly connected to the piston ends of the hydraulic cylinders 21. With the clamping mechanism 2, when clamping boiler parts, the end face of the boiler parts is first placed on the base 1, and then the two hydraulic cylinders 21 are activated to drive the two main clamping plates 22 to move closer to each other, so that the main clamping plates 22 abut against the outer walls of both sides of the boiler parts, and the boiler parts are initially clamped.

[0021] The base 1 has a groove 11 on its top, and a slider 25 is fixedly connected to the bottom of the main clamping plate 22. The slider 25 is slidably connected in the groove 11. Through the cooperation of the groove 11 and the slider 25, the main clamping plate 22 can be slidably guided, which can improve the stability of the main clamping plate 22.

[0022] Furthermore, two symmetrically distributed auxiliary clamping plates 23 are hinged to one side of each of the two main clamping plates 22 that are close to each other. A driving component 24 for driving the auxiliary clamping plates 23 to rotate is provided inside the main clamping plate 22. With the auxiliary clamping plates 23 and the driving component 24, after the main clamping plate 22 abuts against the boiler accessory, the driving component 24 can be activated to drive the two auxiliary clamping plates 23 on the same main clamping plate 22 to rotate in opposite directions, so that the four auxiliary clamping plates 23 abut against the surrounding outer wall of the boiler accessory respectively, and cooperate with the main clamping plate 22 to assist in clamping the boiler accessory, so that the boiler accessory is subjected to force at multiple points, thereby improving the clamping effect and stability.

[0023] Specifically, the driving component 24 includes a bidirectional screw 241 rotatably installed in the main clamping plate 22. The bidirectional screw 241 is horizontally arranged along the length of the main clamping plate 22. Two symmetrically distributed connecting blocks 242 are threaded onto the bidirectional screw 241. A connecting rod 243 is hinged between the connecting blocks 242 and the auxiliary clamping plate 23. A motor 244 is fixedly installed at one end of the main clamping plate 22. A strip-shaped sliding hole 26 is opened on the side of the main clamping plate 22 near the auxiliary clamping plate 23. The connecting blocks 242 are slidably connected in the strip-shaped sliding hole 26. With the setting of the driving component 24, when using the auxiliary clamping plate 23, the motor 244 can be started to drive the bidirectional screw 241 to rotate, so that the bidirectional screw 241 drives the two connecting blocks 242 to slide in opposite directions along the strip-shaped sliding hole 26. The connecting blocks 242 drive the two auxiliary clamping plates 23 to rotate synchronously through the connecting rod 243, thereby adjusting the included angle of the two auxiliary clamping plates 23, which is convenient for clamping boiler accessories of different diameters.

[0024] The working principle and usage process of this utility model are as follows: First, when clamping the boiler parts, the end face of the boiler parts is placed on the base 1. Then, the two hydraulic cylinders 21 are started to drive the two main clamping plates 22 to move closer to each other, so that the main clamping plates 22 abut against the outer walls of both sides of the boiler parts, and the boiler parts are initially clamped. Then, the motor 244 can be started to drive the bidirectional screw 241 to rotate, so that the bidirectional screw 241 drives the two connecting blocks 242 to slide in opposite directions along the strip-shaped sliding hole 26, so that the connecting blocks 242 drive the two auxiliary clamping plates 23 to rotate synchronously through the connecting rod 243. The included angle of the two auxiliary clamping plates 23 can be adjusted so that the four auxiliary clamping plates 23 abut against the outer walls of the boiler parts respectively, and cooperate with the main clamping plates 22 to assist in clamping the boiler parts, so that the boiler parts are subjected to force at multiple points, improving the clamping effect and stability.
