Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of excavator connecting rod processing, in particular to a double-station machining fixture for excavator connecting rods. Background Technique
[0002] In the process of excavator connecting rod processing, traditional processing methods often adopt single-station processing methods, that is, only one connecting rod is processed at a time. This processing method has low efficiency and is difficult to meet the needs of large-scale production. With the development of automation technology, mechanical devices for multi-station simultaneous processing have emerged. However, in the existing technical solutions, there are still some deficiencies in the double-station machining fixture for excavator connecting rods.
[0003] In the existing double-station machining fixture for excavator connecting rods, two fixture jigs are usually used to clamp and fix the workpiece. When the connecting rod workpiece needs to be turned over, the operator needs to release the fixation of the workpiece and then re-fix it, which is cumbersome and inefficient. Content of the Utility Model
[0004] The purpose of the utility model is to provide a double-station machining fixture for excavator connecting rods to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A double-station machining fixture for excavator connecting rods, including a bracket, a turntable and an installation box. A mounting seat is installed on the top of the bracket. The turntable is rotatably installed on the top of the mounting seat through a bearing. Mounting holes are provided on the front of the turntable. An installation box is fixedly installed on the back of the mounting seat. A servo motor is fixedly installed on the back of the installation box. Two sets of fixture components are installed on the front of the turntable through the mounting holes. The fixture component includes a mounting plate, a hydraulic push rod, a linkage arm and a clamping arm. A hydraulic push rod is fixedly installed on one side of the top of the mounting plate. A clamping arm is installed on one side of the top of the mounting plate through a rotating shaft. The output end of the hydraulic push rod is installed with a linkage arm, and one end of the linkage arm is connected to the clamping arm through a rotating shaft.
[0006] Both the bracket and the mounting base are made of high-strength materials, with stable structures, capable of bearing the weight of the turntable and the fixture assembly as well as the vibrations generated during the machining process. The turntable is driven by a servo motor, which adopts a high-precision control algorithm and can precisely control the rotation speed and angle of the turntable. Through programming settings, automatic positioning and rotation of the turntable and the fixture assembly can be achieved, reducing the errors and labor intensity of manual operations. When the hydraulic push rod operates, it pushes the clamping arm through the linkage arm, enabling the clamping arm to clamp the workpiece. Since the fixture assembly adopts a hydraulic drive method, it has the advantages of large clamping force, good stability, and simple operation. The design of the clamping arm fully considers the shape and size of the workpiece to ensure firm clamping without damaging the workpiece. Since this device adopts a dual-installed machine design, two workpieces can be processed simultaneously, thus greatly improving the processing efficiency. The workpiece can rotate during the clamping process, so that the staff can process and inspect different angles of the workpiece without flipping the workpiece, which is more convenient and labor-saving.
[0007] Preferably, a transmission gear is installed on the back of the turntable.
[0008] The transmission gear is installed on the turntable, and when the transmission gear rotates, it can drive the turntable to rotate.
[0009] Preferably, a drive gear is installed at the output end of the servo motor, and the drive gear meshes with the transmission gear.
[0010] Since the drive gear meshes with the transmission gear, when the servo motor drives the drive gear to operate, it can drive the transmission gear to operate. Through the operation of the transmission gear, the mounting hole can be rotated, and then the fixture assembly can be rotated.
[0011] Preferably, the input end of the hydraulic push rod is connected to an external hydraulic pump.
[0012] Since the input end of the hydraulic push rod is connected to an external hydraulic pump (not shown in the figure), it can provide driving force for the operation of the hydraulic push rod.
[0013] In summary, the present application includes the following beneficial technical effects:
[0014] This device adopts a dual-installed machine design, and two workpieces can be processed simultaneously, thus greatly improving the processing efficiency. The workpiece can rotate during the clamping process, so that the staff can process and inspect different angles of the workpiece without flipping the workpiece, which is more convenient and labor-saving.

[0030] Example 1
[0031] As Figure 1 , Figure 2 , Figure 3 shown, a machining fixture for a double-link of an excavator connecting rod proposed by the present utility model includes a bracket 1, a turntable 2, and an installation box 3. A mounting seat 101 is installed at the top of the bracket 1. The turntable 2 is rotatably installed at the top of the mounting seat 101 through a bearing. An installation hole 202 is provided on the front surface of the turntable 2. An installation box 3 is fixedly installed on the back of the mounting seat 101. A servo motor 301 is fixedly installed on the back of the installation box 3. Two sets of fixture assemblies 4 are installed on the front surface of the turntable 2 through the installation hole 202. The fixture assembly 4 includes a mounting plate 401, a hydraulic push rod 402, a linkage arm 403, and a clamping arm 404. A hydraulic push rod 402 is fixedly installed on one side of the top of the mounting plate 401. A clamping arm 404 is installed on one side of the top of the mounting plate 401 through a rotating shaft. The output end of the hydraulic push rod 402 is installed with a linkage arm 403, and one end of the linkage arm 403 is connected to the clamping arm 404 through a rotating shaft.
[0032] The working principle of the machining fixture for the double-link of the excavator connecting rod based on Embodiment 1 is as follows: The bracket 1 and the mounting seat 101 are both made of high-strength materials, with stable structures, capable of bearing the weights of the turntable 2 and the fixture assembly 4, as well as the vibrations generated during the machining process. The turntable 2 is driven by the servo motor 301. The servo motor 301 adopts a high-precision control algorithm, capable of precisely controlling the rotation speed and angle of the turntable 2. Through programming settings, automatic positioning and rotation of the turntable 2 and the fixture assembly 4 can be achieved, reducing the errors and labor intensity of manual operations. When the hydraulic push rod 402 operates, it pushes the clamping arm 404 through the linkage arm 403, enabling the clamping arm 404 to clamp the workpiece. Since the fixture assembly 4 adopts a hydraulic drive method, it has the advantages of large clamping force, good stability, and simple operation. The design of the clamping arm 404 fully considers the shape and size of the workpiece to ensure firm clamping without damaging the workpiece. Since this device adopts a double-link machine design, two workpieces can be machined simultaneously, thus greatly improving the machining efficiency. The workpiece can rotate during the clamping process, facilitating the staff to machine and inspect different angles of the workpiece without flipping the workpiece, which is more convenient and labor-saving.
[0033] Embodiment 2
[0034] As Figure 1 , Figure 2 , Figure 3 shown, a machining fixture for a double-link of an excavator connecting rod proposed by the present utility model. Compared with Embodiment 1, this embodiment further includes: A transmission gear 201 is installed on the back of the turntable 2. The output end of the servo motor 301 is installed with a driving gear 302. The driving gear 302 meshes with the transmission gear 201. The input end of the hydraulic push rod 402 is connected to an external hydraulic pump.
[0035] In this embodiment, as Figure 2 shown, the transmission gear 201 is installed on the turntable 2, and the rotation of the transmission gear 201 can drive the rotation of the turntable 2; as Figure 1 , Figure 2 shown, since the driving gear 302 meshes with the transmission gear 201, it can drive the transmission gear 201 to operate when the servo motor 301 drives the driving gear 302 to operate. The rotation of the transmission gear 201 can drive the rotation of the mounting hole 202, thereby causing the fixture assembly 4 to rotate; as Figure 3 shown, since the input end of the hydraulic push rod 402 is connected to an external hydraulic pump (not shown in the figure), it can provide driving force for the operation of the hydraulic push rod 402.
[0036] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
