[0015] This invention, by incorporating a clamping mechanism, can fix the main body of the wheel excavator's underframe in the X, Y, and Z directions. This avoids the problem of reduced effectiveness that often arises with traditional devices that rely on bolts for fixation. A drive motor, supported by a connecting plate, rotates a threaded rod around the inner wall of a U-shaped groove. This rotation causes the U-shaped block, servo motor, X-axis clamping frame, and the screw, T-block, and moving block structures within the X-axis clamping frame to slide along the moving groove. The X-axis clamping frames on both sides of the wheel excavator's underframe then clamp and fix the main body of the wheel excavator along the X-axis. The servo motor drives... The lead screw rotates, which in turn drives the T-block and the moving block to slide back and forth along the inside of the T-slot. The sliding of the moving block in turn drives the Y-axis clamping frame to slide back and forth, thus fixing the main body of the wheel excavator under frame in the Y-axis direction. The sliding frame slides along the inside of the guide groove, and the main body of the wheel excavator under frame is fixed in the Z-axis direction by the electric push rod under the support of the Z-axis fixing frame. This device achieves three-dimensional fixation of the main body of the wheel excavator under frame, effectively improving the clamping efficiency of the device and avoiding the traditional device that only uses fixing bolts to fix the main body of the wheel excavator under frame, which is not only time-consuming and labor-intensive, but also reduces the working efficiency of the device.

The clamping mechanism 2 includes a connecting plate 201, and a controller body 204 is fixedly connected to the upper surface of the wheeled excavator underframe body 1. Two U-shaped grooves 219 are formed on the upper surface of the connecting plate 201. Two U-shaped blocks 217 are slidably connected inside each U-shaped groove 219. A threaded rod 218 is rotatably connected to the inner wall of each U-shaped block 217. A drive motor 205 is disposed on the outer side of each threaded rod 218. The outer surface of each drive motor 205 is... A stabilizing plate 5 is fixedly connected. The upper surface of the connecting plate 201 is in contact with the bottom surface of the wheel digger lower frame body 1. The right side of each stabilizing plate 5 is fixedly connected to the left side of the connecting plate 201. The output end of each servo motor 202 is fixedly connected to the end of the lead screw 206 near the controller body 204. The output end of each drive motor 205 is fixedly connected to the left end of the threaded rod 218. By using the stabilizing plate 5, the drive motor 205 can be fixed, avoiding the problem of the drive motor 205 shaking during use, which would affect the stability of the drive motor 205.

[0025] Each set of U-shaped blocks 217 has an X-axis clamping frame 203 fixedly connected to its upper surface. Each X-axis clamping frame 203 has a T-slot 207 on its upper surface. Each T-slot 207 has a lead screw 206 rotatably connected to its inner wall. Each X-axis clamping frame 203 has a servo motor 202 on its outer side. Each servo motor 202 has an L-shaped plate 4 fixedly connected to its outer surface. The back of each L-shaped plate 4 is fixedly connected to the front of the X-axis clamping frame 203. The L-shaped plate 4 can be used to reinforce the servo motor 202 and prevent the servo motor 202 from shaking during use, which would affect the clamping effect of the device on the main body 1 of the wheel digger frame. Example

[0026] Please see Figure 1-6 Each lead screw 206 has a T-block 216 threadedly connected to its outer surface. Each T-block 216 has a moving block 215 fixedly connected to its upper surface. Two Y-axis clamping frames 209 are provided above the connecting plate 201. Each Y-axis clamping frame 209 has a guide groove 220 on its upper surface. Each guide groove 220 has a sliding frame 212 slidably connected inside. Each guide groove 220 has a guide rod 6 fixedly connected to its inner wall. The outer surface of each guide rod 6 is slidably connected to the inside of the sliding frame 212. The guide rod 6 facilitates the movement of the sliding frame 212, thereby improving the efficiency of the sliding frame 212's movement.

[0027] Each sliding frame 212 has a Z-axis fixing frame 213 fixedly connected to its upper surface. Each Y-axis clamping frame 209 has several identical threaded holes 210 on its upper surface. The inner wall of each sliding frame 212 is threaded with two bolts 211 to the inner wall of the threaded holes 210.

The electric push rod 214, also known as a linear actuator, is a new type of linear actuator mainly composed of a motor push rod and a control device. It can be considered as an extension of the rotary motor in terms of structure.

[0028] Each Y-axis clamping bracket 209 has a sliding groove 208 on its bottom surface. The interior of each sliding groove 208 is slidably connected to the outer surface of the sliding block 215. A fixing frame 3 is fixedly connected to the outer surface of the controller body 204. The bottom surface of the fixing frame 3 is fixedly connected to the upper surface of the connecting plate 201. The controller body 204 is electrically connected to the drive motor 205, the servo motor 202 and the electric push rod 214 through wires. The fixing frame 3 can fix the controller body 204 to prevent it from shaking during use, thus affecting the stability of the controller body 204. The controller body 204 is a master command device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is the "decision-making body" that issues commands, that is, it completes the coordination and command of the operation of the entire computer system. Example

[0029] The working principle of this utility model is as follows: During use, the operator connects the controller body 204, drive motor 205, servo motor 202, and electric push rod 214 to the power supply. When using this device, the operator places the wheel-shaped undercarriage body 1 to be machined on the upper surface of the connecting plate 201. Then, the operator uses the controller body 204 to control the drive motor 205. Under the support of the connecting plate 201 and the U-shaped groove 219, the drive motor 205 drives the threaded rod 218 to rotate. Since the threaded rod 218 is threadedly connected to the U-shaped block 217, the rotation of the threaded rod 218 drives the U-shaped block 217, the X-axis clamping frame 203, and the lead screw 206, T-shaped block 216, and servo push rod 214 within the X-axis clamping frame 203. The machine 202 and other structures slide left and right along the inside of the U-shaped groove 219. During the left and right sliding of the T-shaped block 216, it drives the moving block 215 to slide along the inside of the moving groove 208, so that the two X-axis clamping frames 203 move closer to each other, achieving the purpose of clamping and fixing the main body of the wheel digger frame in the 1-axis direction. Then, the operator uses the controller body 204 to control the servo motor 202 to work. Under the support of the X-axis clamping frame 203, the servo motor 202 drives the lead screw 206 to rotate. Since the lead screw 206 is threadedly connected to the T-shaped block 216, the rotation of the lead screw 206 drives the T-shaped block 216 to slide back and forth along the inside of the T-shaped groove 207. Since the T-shaped block 216 and the moving block 215 are fixed, the back and forth sliding of the T-shaped block 216 causes the moving block 215 to slide back and forth. The Y-axis clamping bracket 209 and the bolts 211, sliding bracket 212, Z-axis fixing bracket 213, threaded hole 210, and guide groove 220 within the Y-axis clamping bracket 209, along with other Y-axis and Z-axis fixing structures, approach each other to the surface of the wheel excavator lower frame body 1. When the Y-axis clamping bracket 209 approaches the surface of the wheel excavator lower frame body 1, the operator uses the controller body 204 to control the servo motor 202 to stop working, thus achieving clamping and fixing of the wheel excavator lower frame body 1 in the Y-axis direction. Then, according to the clamping requirements of the wheel excavator lower frame body 1, the operator manually applies a horizontal thrust to the sliding bracket 212. The sliding bracket 212, subjected to this horizontal thrust, moves both sets of sliding brackets 212 to the fixed position of the wheel excavator lower frame body 1. Afterwards, the operator... The operator uses bolts 211 to thread the two sets of sliding frames 212 to the threaded holes 210. Then, the controller body 204 controls the extension and retraction of the electric push rod 214. The extension and retraction of the electric push rod 214 causes the protective pad 7 to contact the surface of the wheel digger underframe body 1, thereby fixing the wheel digger underframe body 1 in the Z-axis direction. This device can fix the wheel digger underframe body 1 in the X, Y and Z directions, thus ensuring that the wheel digger underframe body 1 is in a stable state during processing, thereby ensuring the accuracy of the processing of the wheel digger underframe body 1. This device can accurately fix the wheel digger underframe body 1, avoiding the problem of reduced device performance that can easily occur with traditional devices that only use fasteners to fix the wheel digger underframe body 1.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
