Description

Technical Field

[0001] This utility model belongs to the field of track plate repair technology, and in particular relates to a clamping device that facilitates the repair of track plate workpieces. Background Technology

[0002] Track shoes are an important component of track tracks in construction machinery (such as excavators, bulldozers, and tracked cranes), and are typically cast from high manganese steel or other wear-resistant alloy materials. However, during long-term use, track shoes will experience wear, cracks, or deformation due to frequent friction and impact with hard objects such as the ground and rocks. Therefore, maintenance work such as welding repair, straightening, or surface grinding is required to extend their service life and reduce equipment operating costs.

[0003] Currently, track plates are typically clamped and fixed on a workbench for manual inspection and repair during repair. However, most existing clamping devices have simple structures, often using fixed fixtures, which cannot adapt to track plates of different lengths and specifications, resulting in poor versatility. Furthermore, track plate repair often requires welding and grinding on multiple sides or different parts, and traditional fixtures cannot flexibly rotate the workpiece. Operators need to frequently disassemble or adjust the clamping position of the track plates, leading to low repair efficiency and affecting repair quality. Therefore, there is an urgent need for a clamping device that can quickly adapt to different specifications of track plates and facilitate adjustment of the workpiece angle during the repair process.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0034] Please see Figures 1 to 5 This utility model provides a clamping device for easily repairing track plate workpieces, used to clamp and fix track plate 6, including frame 1 and fixed seat 2 and movable seat 3 installed in frame 1. A clamping component 4 is rotatably installed on fixed seat 2 and movable seat 3 respectively, and the two clamping components 4 are arranged opposite to each other.

[0035] The frame 1 includes a base 11, which is configured as a "U" shaped structure. The fixed seat 2 is installed inside the base 11 on one side, and the movable seat 3 is movably installed inside the base 11 on the other side opposite to the fixed seat 2.

[0036] Both clamping assemblies 4 include a rotating disk 41, with a rotating shaft 411 mounted on one side of the rotating disk 41. The two rotating shafts 411 are coaxially arranged. A clamping unit 42 is mounted on the other side of the rotating disk 41 opposite to the rotating shaft 411. The two clamping units 42 on the two clamping assemblies 4 respectively clamp the two ends of the track plate 6.

[0037] In practical application, this embodiment first adjusts the position of the movable seat 3 by rotating the adjusting rod 32 according to the length of the track plate 6, so that the distance between the two clamping components 4 is adapted to the length of the track plate 6; then the two ends of the track plate 6 are clamped by the two clamping units 42 respectively. In use, the track plate 6 can rotate around the pivot 411 as the central axis, and the angle of the track plate 6 can be freely adjusted, so as to facilitate the operator to perform repair work on different parts of the track plate 6.

[0038] This embodiment can adapt to track plates 6 of different lengths by adjusting the relative distance between the fixed seat 2 and the movable seat 3, thus improving the versatility of the equipment. At the same time, the two clamping units 42 can stably clamp the two ends of the track plate 6 respectively, and the whole can rotate synchronously around the rotating shaft 411, which makes it convenient for operators to perform continuous repair work on different parts of the track plate without disassembling the workpiece, significantly improving repair efficiency and operational convenience.

[0039] Please see Figure 3 and Figure 4In a preferred embodiment of this utility model, the movable seat 3 includes a movable seat body 31 and an adjusting rod 32. A support plate 13 is provided in the middle of the base 11, and a fixed plate 14 is provided at one end of the base 11. The two ends of the adjusting rod 32 are respectively rotatably installed on the sides of the support plate 13 and the fixed plate 14. The movable seat body 31 and the fixed seat 2 are both configured with the same "L" shaped structure. The two rotating shafts 411 are respectively rotatably installed on the vertical plates of the movable seat body 31 and the fixed seat 2. The bottom of the movable seat body 31 is slidably disposed in the base 11 and threadedly engaged with the adjusting rod 32.

[0040] Furthermore, a guide bar 15 is provided on the inner wall of the base 11. The guide bar 15 is arranged parallel to the axis of the adjusting rod 32. A guide groove 311 adapted to the size of the guide bar 15 is provided on the side of the movable seat body 31 at the position corresponding to the guide bar 15. The guide groove 311 slides with the guide bar 15.

[0041] In this embodiment, the adjusting rod 32, in conjunction with the movable seat body 31, allows for precise adjustment and self-locking of the position of the movable seat body 31 by rotating the adjusting rod 32 under the action of the threaded engagement. This facilitates the adjustment of the relative distance between the movable seat 3 and the fixed seat 2, adapting to track plates 6 of different specifications and lengths, thus improving the versatility of the equipment. At the same time, the sliding engagement between the guide bar 15 and the guide groove 311 ensures the straightness and stability of the movable seat body 31 during movement, preventing the track plates 6 from being clamped and misaligned.

[0042] Please see Figure 2 , Figure 4 and Figure 5 In another preferred embodiment of this utility model, the clamping unit 42 includes:

[0043] Two fixed frames 421 together with two positioning plates 422 form a frame structure, and a center plate 423 is installed in the middle of the frame structure.

[0044] A bidirectional lead screw 424 is rotatably mounted at both ends on the sides of two positioning plates 422, and the middle part of the bidirectional lead screw 424 rotatably passes through the center plate 423.

[0045] Two movable blocks 425 are threadedly installed on the double-acting lead screw 424 and are symmetrically located on both sides of the center plate 423. Each of the two movable blocks 425 is equipped with a clamping plate 426. A pad 427 is installed on the opposite side of the two clamping plates 426. The pad 427 is in contact with the two sides of the end of the track plate 6.

[0046] Furthermore, limit blocks 4251 are provided on both sides of the movable block 425, and the fixed frame 421 is provided with a limit groove 4211 that matches the size of the limit block 4251 at the position corresponding to the limit block 4251. The limit block 4251 can slide within the limit groove 4211.

[0047] In this embodiment, the two movable blocks 425 are driven to move synchronously in opposite directions or in opposite directions by the bidirectional lead screw 424, thereby enabling the clamping plate 426 and the pad block 427 to quickly center and clamp the end of the track plate 6 without the need for additional adjustment of the center position. The limiting block 4251 and the limiting groove 4211 are matched to ensure the linearity and stability of the movement of the movable block 425, further improving the clamping reliability.

[0048] In one embodiment, the pad 427 can be made of flexible or wear-resistant material, such as rubber pad, polyurethane pad or copper pad, which can increase friction and protect the track plate surface from damage. This ensures a firm clamping while avoiding indentations or scratches on the track plate 6 surface, and is suitable for repairing track plates 6 with worn or finished surfaces.

[0049] Please see Figure 2 and Figure 3 In another preferred embodiment of this utility model, a driving component 5 is further included for driving the two clamping components 4 to rotate synchronously. The driving component 5 includes:

[0050] Motor 51, the other end of the base 11 opposite to the fixing plate 14 is provided with a mounting plate 12, and the motor 51 is mounted on the side of the mounting plate 12;

[0051] The drive shaft 52 is fixedly connected to the power output end of the motor 51 and rotates through the mounting plate 12, the fixed seat 2 and the support plate 13 in sequence.

[0052] Driven shaft 53 is rotatably mounted on movable seat body 31, and one end of it is provided with transmission rod 531, which is movably inserted into drive shaft 52;

[0053] The transmission unit 54 is used to transmit power from the drive shaft 52 and the driven shaft 53 to the rotating shaft 411.

[0054] In this embodiment, the motor 51 drives the drive shaft 52 to rotate, and the drive shaft 52 drives the driven shaft 53 to rotate synchronously through the transmission rod 531. Since the transmission rod 531 and the drive shaft 52 are slidably connected by a plug-in fit, the transmission rod 531 can extend and retract relative to the drive shaft 52 when the movable seat body 31 moves, so as to always transmit power to the driven shaft 53, thereby driving the two rotating shafts 411 to rotate synchronously, realizing the synchronous rotation of the two clamping units 42, and ensuring that the track plate 6 will not be twisted or asynchronous during rotation.

[0055] Please see Figure 2 In another preferred embodiment of this utility model, the transmission unit 54 includes:

[0056] Two driven sprockets 542 are fixedly mounted on two rotating shafts 411 respectively;

[0057] Two drive sprockets 541 are fixedly mounted on drive shaft 52 and driven shaft 53 respectively, and are positioned opposite to the driven sprockets 542 mounted on two rotating shafts 411. The drive sprockets 541 and the opposite driven sprockets 542 are connected by a chain 543.

[0058] In this embodiment, a sprocket-chain transmission is formed by the driving sprocket 541, the driven sprocket 542 and the chain 543. The structure is simple, the transmission ratio is accurate and the impact resistance is strong. At the same time, the driving sprocket 541 and the driven sprocket 542 are arranged in opposite positions to ensure the stability and synchronization of power transmission.

[0059] In one embodiment, the transmission unit 54 can also be configured as a synchronous belt drive or a gear drive. For example, the driving sprocket and driven sprocket can be replaced with synchronous pulleys and connected by a synchronous belt; or a set of meshing gear pairs can be used to transmit the power of the driving shaft and driven shaft to the two rotating shafts respectively. As long as the synchronous rotation function of the two clamping units 42 can be achieved, it is a conventional design choice for those skilled in the art, and this utility model does not further limit it.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0061] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
