Description

Technical Field

[0001] The utility model relates to the technical field of automobile shaft part processing and fixing, and specifically relates to a multi-station automobile shaft part processing and fixing device. Background Technique

[0002] Automobile shaft parts are crucial components in the automobile structure. They not only bear the weight of the vehicle body but also are responsible for transmitting power, connecting various systems, and ensuring the stability and smoothness of the vehicle. The automobile shaft part processing and fixing device is to ensure that the automobile shaft parts maintain a stable and precise position during the processing process to facilitate high-precision processing operations.

[0003] Moreover, the multi-station automobile shaft part processing and fixing device is designed to meet the need for multi-station collaborative operation of automobile shaft parts during the production process. Usually, multiple stations are set on one device, which can realize the multi-station collaborative processing of automobile shaft parts and improve production efficiency.

[0004] During the processing of multi-station shaft part processing equipment, the method of fixing and processing one by one is generally adopted. Since only one shaft part can be fixed and processed each time, the equipment needs to perform a series of operations such as stopping, loading and unloading parts, and restarting after completing the processing of one shaft part before it can process the next shaft part.

[0005] In the prior art, multi-station shaft part processing equipment often sets multiple fixing mechanisms to fix the corresponding number of workpieces to solve the problem of independent processing. However, each fixing mechanism requires an independent drive source, which increases the use cost of the equipment. Therefore, those skilled in the art have provided a multi-station automobile shaft part processing and fixing device to solve the problems raised in the above background technique. Content of the Utility Model

[0006] (1) Technical Problems to be Solved

[0007] Aiming at the deficiencies of the prior art, the utility model provides a multi-station automobile shaft part processing and fixing device to solve the problem that in the existing multi-station shaft part processing equipment, multiple fixing mechanisms are often set to fix the corresponding number of workpieces to solve the problem of independent processing, but each fixing mechanism requires an independent drive source, resulting in an increase in the use cost of the equipment.

[0008] (2) Technical Solutions

[0009] To achieve the above object, the present utility model provides the following technical solution: A multi-station fixing device for machining automotive shaft parts, including a fixed seat, a fixed block is installed on the fixed seat, an inner ring is installed on the fixed block, an outer ring is sleeved outside the inner ring, a fixed rod is installed on the outer wall of the outer ring, a connecting rod is connected to the fixed rod, a connecting piece is arranged on one side of the fixed block, a hydraulic cylinder is rotatably connected to the connecting piece, and the output end of the hydraulic cylinder is rotatably sleeved with the fixed rod on the outer wall of the outer ring. Adjacent outer rings are connected by a connecting rod and a fixed rod. When the outer ring at one end of the fixed seat rotates, the adjacent outer rings can be driven to rotate under the drive of the connecting rod.

[0010] First positioning holes are opened on the front and rear sides of the inner ring, second positioning holes are opened on one side of the first positioning holes, third positioning holes are opened on the front and rear sides of the outer ring, fourth positioning holes are opened on one side of the third positioning holes, first limiting shafts are arranged on the front and rear sides of the inner ring, a first rotating block is installed at one end of the first limiting shaft, a first limiting sleeve is sleeved at the other end of the first limiting shaft, a second limiting shaft is arranged on one side of the first limiting shaft, a second rotating block is installed at one end of the second limiting shaft, and a second limiting sleeve is sleeved at the other end of the second limiting shaft.

[0011] Preferably, two first limiting shafts are arranged in parallel, and two second limiting shafts are arranged in parallel.

[0012] Preferably, the first positioning hole is rotationally clamped with the first limiting sleeve, the second positioning hole is rotationally clamped with the second limiting sleeve, the third positioning hole is rotationally clamped with the first rotating block, the fourth positioning hole is rotationally clamped with the second rotating block, the first limiting shaft is slidably sleeved with the first limiting sleeve, and the second limiting shaft is slidably sleeved with the second limiting sleeve. When the hydraulic cylinder contracts, the outer ring is pulled to rotate around the inner ring through the fixed rod. And when the outer ring rotates, the first rotating block and the second rotating block rotationally clamped on the outer ring rotate. Since the other ends of the first limiting shaft and the second limiting shaft on the first rotating block and the second rotating block are slidably sleeved with the first limiting sleeve and the second limiting sleeve on the inner ring, the distance between the mutually parallel first limiting shafts and the mutually parallel second limiting shafts gradually decreases, so as to achieve clamping and fixing of the workpiece.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present utility model provides a multi-station fixing device for machining automotive shaft parts, which has the following beneficial effects:

[0015] By design, when the hydraulic cylinder contracts, the outer ring is pulled by the fixed rod to rotate around the inner ring. And when the outer ring rotates, the first rotating block and the second rotating block rotatably clamped on the outer ring rotate. Since the other ends of the first limiting shaft and the second limiting shaft on the first rotating block and the second rotating block are slidably sleeved with the first limiting sleeve and the second limiting sleeve on the inner ring, the distance between the mutually parallel first limiting shafts and the mutually parallel second limiting shafts gradually decreases, so as to achieve the clamping and fixing of the workpiece. And adjacent outer rings are connected by connecting rods and fixed rods. When the outer ring at one end of the fixed seat rotates, driven by the connecting rod, the adjacent outer rings can also be driven to rotate, resulting in the effect that the device can drive multiple fixing mechanisms with a single drive source configuration, reducing the use cost.
