Technical Field

[0001] This application relates to the field of automotive parts processing technology, specifically a multi-station fixture for manufacturing the inner holes of automotive parts. Background Technology

[0002] In the machining of automotive parts, some parts require internal hole machining. This involves creating holes inside cylindrical workpieces to facilitate subsequent part installation. When creating these internal holes, fixtures are needed to stably hold the automotive parts. However, existing fixtures tend to cause the automotive parts to wobble when clamping them, resulting in inaccurate hole drilling and affecting the machining process.

[0003] Therefore, there is an urgent need for a multi-station fixture for manufacturing the inner holes of automotive parts to solve the problem of easy shaking when opening holes in automotive parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a multi-station fixture for manufacturing inner holes in automotive parts, which has the advantage of improving the stability of hole openings in automotive parts and solves the problem of easy shaking of hole openings in automotive parts.

[0005] To achieve the above objectives, this application provides the following technical solution: a multi-station fixture for manufacturing inner holes of automotive parts, comprising a fixed frame and a support plate, wherein the support plate is welded to the inner side of the fixed frame, a support mechanism is provided on the inner side of the fixed frame, and clamping mechanisms are provided on both sides of the fixed frame;

[0006] The clamping mechanism includes a support frame, a hydraulic cylinder, a connecting rod, clamping plates, and gaskets. The support frame is welded to both sides of the support plate. The hydraulic cylinder is installed on the outside of the support frame. One end of the connecting rod is fixedly connected to the output end of the hydraulic cylinder, and the other end of the connecting rod is fixedly connected to the outside of the clamping plates. Several sets of gaskets are bonded to the grooves on the inside of the clamping plates.

[0007] By adjusting the position of the clamping plates, when the two sets of clamping plates move inward, the clamping plates drive the pads to clamp onto the outer surface of the cylindrical automotive parts, thereby fixing the automotive parts and making them less prone to shaking when making holes, thus improving the stability of the automotive parts.

[0008] Preferably, the outer side of the clip is slidably connected to the groove on the inner side of the support plate.

[0009] Preferably, the clip is a plate with an arc-shaped structure.

[0010] Preferably, the connecting rod is connected to the clamp by screws.

[0011] Preferably, the support mechanism includes a drive motor, a threaded rod, a support rod, and a support plate. The drive motor is installed inside the fixed frame. One end of the threaded rod is fixedly connected to the output end of the drive motor. The other end of the threaded rod is threadedly connected to one end of the support rod. The other end of the support rod is fixedly connected to the bottom of the support plate by screws. A circular slot is provided at the center of the top of the support plate.

[0012] Preferably, a fixing frame is slidably connected to the outer surface of the support rod, and the two ends of the fixing frame are welded to the inner side of the fixing frame.

[0013] In summary, this application includes at least one of the following beneficial effects:

[0014] 1. This multi-station fixture for manufacturing inner holes of automotive parts allows the cylindrical automotive parts to be inserted into the slot at the top of the support plate when the parts are being drilled. By adjusting the position of the clamping plates, when the two sets of clamping plates move inward, the clamping plates drive the pads to clamp the outer surface of the cylindrical automotive parts, thereby fixing the automotive parts and making them less prone to shaking when drilling, thus improving the stability of the automotive parts.

[0015] 2. This multi-station fixture for manufacturing inner holes of automotive parts allows the support rod to be adjusted to move the support plate up and down during hole drilling. This changes the height of the support plate, which then supports the automotive parts. This allows the fixture to hold automotive parts of different lengths, making it more convenient to use.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-4 A multi-station fixture for manufacturing inner holes of automotive parts includes a fixed frame 1 and a support plate 2. The support plate 2 is welded to the inner side of the fixed frame 1. The bottom two sides of the fixed frame 1 can be fixed with screws so that the fixed frame 1 can be installed in a suitable position. The automotive parts can be inserted into the slots on the inner side of the support plate 2 for fixing. The fixed frame 1 can clamp and fix multiple automotive parts, so that the fixture can fix automotive parts in multiple stations. A support mechanism is provided on the inner side of the fixed frame 1, and clamping mechanisms are provided on both sides of the fixed frame 1.

[0023] Specifically, the clamping mechanism includes a support frame 111, a hydraulic cylinder 112, a connecting rod 113, a clamping plate 114, and a gasket 115. The support frame 111 is welded to both sides of the support plate 2. The hydraulic cylinder 112 is installed on the outside of the support frame 111. One end of the connecting rod 113 is fixedly connected to the output end of the hydraulic cylinder 112, and the other end of the connecting rod 113 is fixedly connected to the outside of the clamping plate 114. The clamping plate 114 is an arc-shaped plate. The connecting rod 113 is connected to the clamping plate 114 by screws. Several sets of gaskets 115 are bonded to the grooves on the inner side of the clamping plate 114. The outer side of the clamping plate 114 is slidably connected to the grooves on the inner side of the support plate 2.

[0024] With the above technical solution, when the automotive parts are being drilled, the cylindrical automotive parts are inserted into the slot at the top of the support plate 2. The operator starts the hydraulic cylinder 112, which drives the clamping plate 114 to move through the connecting rod 113, thereby adjusting the position of the clamping plate 114. When the two sets of clamping plates 114 move inward, the clamping plate 114 drives the pad 115 to clamp the outer surface of the cylindrical automotive parts, thereby fixing the automotive parts and making them less prone to shaking when drilling, thus improving the stability of the automotive parts.

[0025] Specifically, the support mechanism includes a drive motor 211, a threaded rod 212, a support rod 213, and a support plate 214. The drive motor 211 is installed inside the fixed frame 1. One end of the threaded rod 212 is fixedly connected to the output end of the drive motor 211, and the other end of the threaded rod 212 is threadedly connected to one end of the support rod 213. The other end of the support rod 213 is fixedly connected to the bottom of the support plate 214 by screws. A circular slot is opened in the middle of the top of the support plate 214. A fixing frame 215 is slidably connected to the outer surface of the support rod 213. The two ends of the fixing frame 215 are welded to the inside of the fixed frame 1.

[0026] With the above technical solution, when the automotive parts are being drilled, the drive motor 211 is started, which drives the threaded rod 212 to rotate. When the threaded rod 212 rotates, it drives the support rod 213 to move up and down. By adjusting the height of the support rod 213, the support rod 213 drives the support plate 214 to move up and down. The support plate 214 slides inside the fixed frame 215. By changing the height of the support plate 214, the support plate 214 supports the automotive parts, allowing the clamp to hold automotive parts of different lengths, making the clamp more convenient to use.

[0027] In use, by adjusting the position of the clamping plates 114, when the two sets of clamping plates 114 move inward, the clamping plates 114 drive the pads 115 to clamp the outer surface of the cylindrical automotive parts, thereby fixing the automotive parts and making them less prone to shaking when making holes, thus improving the stability of the automotive parts.

[0028] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
