Description

Technical Field

[0001] This utility model belongs to the field of machining technology, specifically relating to a fixture for machining support rollers. Background Technology

[0002] Track rollers are used to support the weight of tracked vehicles such as excavators, tractors, and tanks. They roll on the track rails or track pads and also restrain the tracks to prevent lateral slippage. Track rollers are typically manufactured by machining forged steel blanks, precision machining both ends on a lathe, and drilling two oil holes on a drilling machine. Proper securing during the machining and assembly process is crucial.

[0003] Track rollers come in various sizes and models, including single-sided and double-sided track rollers. During the machining process, a uniform fixture cannot securely fix all models. Insecure fixing will lead to a decrease in machining accuracy and result in losses. Utility Model Content

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0018] Reference Figure 1-4 This is an embodiment of the present invention, which provides a fixture for machining support rollers, comprising: The displacement assembly 100 includes a base 101, a support block 102 fixedly connected to the top of the base 101, a lubrication sleeve 103 fixedly installed in the inner wall of the support block 102, a moving rod 104 fixedly connected to the inner wall of the support block 102, a servo motor 105 adapted to be installed on the top of the base 101, and a lead screw 106 fixedly connected to the output end of the servo motor 105. The clamp assembly 200 includes a movable platform 201 slidably connected to the side wall of the movable rod 104, a threaded post 202 fixedly connected to the top of the movable platform 201, a clamping block 203 sleeved on the side wall of the threaded post 202, and a limiting hole 204 opened on the side of the clamping block 203, the limiting hole 204 penetrating through the clamping block 203.

[0019] Specifically, the support block 102 is fixedly connected to the top surface of the base 101. A lubrication sleeve 103 is installed inside the support block 102, so that the resistance is smaller when the servo motor 105 drives the lead screw 106 to rotate inside the support block 102. The moving rod 104 is fixedly connected to the opening of the support block 102 on the other side. Both the lead screw 106 and the moving rod 104 pass through the inside of the moving platform 201 to support it. A threaded post 202 is fixedly connected to the top of the moving platform 201. The clamping block 203 can be installed on the surface of the moving platform 201 by aligning the limiting hole 204 on the clamping block 203 with the threaded post 202. The threaded post 202 passes through the limiting hole 204 to play a limiting role.

[0020] The displacement assembly 100 also includes a threaded sleeve 107 formed on the side of the moving platform 201, and a lead screw 106 is threaded to the inner wall of the threaded sleeve 107.

[0021] Furthermore, the mobile platform 201 has a pipe inside, and a threaded sleeve 107 is embedded in the pipe. The lead screw 106 is threadedly connected to the threaded sleeve 107. As the lead screw 106 rotates, the threaded sleeve 107 is subjected to force, causing the mobile platform 201 to move.

[0022] The clamp assembly 200 also includes a retaining nut 205 threaded onto the side wall of the threaded post 202, and the retaining nut 205 is located on the top of the clamp block 203.

[0023] Preferably, one end of the threaded post 202 is fixedly connected to the moving platform 201, and the other end passes through the limiting hole 204 on the clamping block 203 and is threadedly connected to the fixing nut 205. As the fixing nut 205 is tightened, the clamping block 203 is pressed against the moving platform 201 to fix it.

[0024] The lead screw 106 is rotatably connected to the inner wall of the lubrication sleeve 103, and a manual knob 108 is fixedly connected to one end of the lead screw 106. The top of the base 101 is provided with mounting holes 1011, and the mounting holes 1011 are symmetrically installed on the side wall of the base 101.

[0025] It should be noted that when the lead screw 106 rotates, the lubrication sleeve 103 provides a certain lubrication effect, reducing the resistance encountered by the lead screw 106 when rotating within the support block 102. One end of the lead screw 106 is connected to the servo motor 105, and the other end is connected to the manual knob 108. The position of the fixture assembly 200 can be finely adjusted by the manual knob 108. The surface of the base 101 is provided with mounting holes 1011 for adapting and mounting this mechanism onto a corresponding machining lathe.

[0026] During use, the servo motor 105 performs work, and the lead screw 106, which is fixedly connected to the output end, rotates within the support block 102 under the lubrication of the lubrication sleeve 103. The rotation of the lead screw 106 contacts the threaded sleeve 107 and generates force. With the assistance of the moving rod 104, the moving platform 201 is subjected to force and begins to move. After adjusting to a suitable angle, a suitable clamping block 203 is installed and fitted onto the threaded post 202 through the limiting hole 204. Then, the fixing nut 205 is tightened to fix it. A corresponding clamping block 203 is also placed on the inner side of the limiting plate 207, and the limiting post 208 is inserted into the limiting hole 204 to fix it. At this time, the support roller to be processed is placed in, and the liquid in the hydraulic pump 206 pushes the limiting plate 207 to move in the output direction, so that the clamping blocks 203 on both sides touch the support roller and clamp it, waiting for processing.

[0027] In summary, by rotating the lead screw 106 through the servo motor 105, the clamping assembly 200 can be adjusted to move left and right, or fine-tuned by rotating the manual knob 108, making loading, unloading, and processing more convenient. By connecting the threaded post 202 to the threaded nut 205, the clamping block 203 can be quickly replaced and the limit post 208 can be pulled out to replace the clamping block 203. The clamping shape can be changed to match the support rollers of different shapes, making the clamping process more tightly fitted, reducing vibration caused by gaps between the clamping and the product during processing, and improving processing accuracy.
