Description

Technical Field

[0001] The utility model relates to the technical field of four-station zero-point interchangeable fixtures, in particular to a four-station zero-point interchangeable fixture with a fixed stop block for a camera bracket. Background Art

[0002] In the past, product processing usually required a clamping process for each product processed, which was not only inefficient but also consumed a lot of manpower. With the rapid development of the manufacturing industry, single-station processing has been unable to keep up with market demand, so the development of a multi-station processing fixture is very necessary.

[0003] Chinese utility model publication number CN221210728U discloses a multi-station, high-efficiency machining fixture. This fixture base features first mounting holes on both sides for mounting a first fixture body, and a second mounting hole at the top for mounting a second fixture body. The first and second fixture bodies are arranged at right angles. This design allows for rapid interchangeability and polyhedron machining, improving machining efficiency. However, significant room for improvement remains in terms of structural stability and machining efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model proposes a four-position zero-point interchangeable fixture for fixing a stopper of a camera bracket, which has a simple structure, is convenient to clamp and has high processing efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: it includes a machine base, a driving device and a clamping device, the driving device is fixedly installed on the machine base, a rotating flange is provided on the driving device, the clamping device is installed in cooperation with the rotating flange through a quick clamping assembly, the clamping device includes a base, a pressure plate and a fastening bolt, four mounting grooves are provided on the base, the workpieces are placed in the mounting grooves respectively, the pressure plate presses the workpiece, and the fastening bolts pass through the pressure plate and the base for locking.

[0006] Based on the above, four mounting slots are provided on the base, which can clamp four processing workpieces at the same time in conjunction with the pressure plate and the fastening screws, thereby improving work efficiency. The quick clamping assembly can be quickly installed and matched with the rotating flange, simplifying the clamping steps and making clamping more convenient and efficient. At the same time, the rotating flange can drive the clamping device to rotate, realizing the zero-point interchange of four workstations, which not only improves the processing efficiency but also ensures the processing accuracy.

[0007] Furthermore, the driving device also includes a pneumatic motor and a speed regulating box. The rotating flange is arranged at the output end of the speed regulating box, and the pneumatic motor drives the rotating flange to rotate.

[0008] Based on the above, the pneumatic motor drives the rotating flange to rotate, so that the clamp device can achieve zero point interchange of four positions and improve work efficiency. However, the pneumatic motor cannot accurately control the rotation speed of the rotating flange and needs to be regulated by a speed regulating box.

[0009] Furthermore, the installation groove is provided on the end surface of the base, and processing grooves and tool-retracting grooves are further provided on four planes perpendicular to the end surface of the installation groove.

[0010] Based on the above, the processing groove is used for the tool to process the workpiece, and the tool withdrawal groove is used for the tool to withdraw and reset after the processing is completed.

[0011] Furthermore, the pressing plate is provided with protrusions at four positions. When the workpiece is clamped, the protrusions contact the bottom surface of the groove, and the protrusions press the workpiece onto the mounting groove.

[0012] Based on the above, the protrusion and the groove are matched and clamped, so that the clamping effect is more stable.

[0013] Furthermore, a plurality of threaded mounting holes are provided on the lower surface of the base, and the quick clamping assembly is fixedly mounted on the base through the threaded mounting holes.

[0014] Based on the above, the threaded mounting hole is used to install the quick clamping assembly, so that the base can be installed more firmly in cooperation with the quick clamping assembly, thereby ensuring the stability of workpiece processing.

[0015] Furthermore, the quick clamping assembly is provided with a plurality of locking holes, and the locking holes are engaged with the locking blocks on the rotating flange.

[0016] Based on the above, the locking hole and the locking block are used to perform locking cooperation, so that the disassembly and assembly of the clamp device is more convenient and quick.

[0017] In order to more clearly illustrate the above features of the present invention and the objectives to be achieved, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] like Figures 1 to 8 As shown, a four-station zero-point interchangeable fixture for a camera bracket fixed block includes a base 1, a drive device 2 and a clamp device 3. The drive device 2 is fixedly installed on the base 1. The drive device 2 includes a rotating flange 21, an air motor 22 and a speed regulating box 23. The speed regulating box 23 adjusts the output speed of the air motor 22 to an appropriate value, thereby controlling the rotation of the rotating flange 21. A locking block 211 is provided on the rotating flange 21, and the locking block 211 is engaged with the locking hole 311 provided on the quick clamping assembly 31. The clamping device 3 includes a clamping base 32, a pressure plate 33, and fastening bolts 34. The clamping base 32 is provided with four mounting slots 321 for placing the workpiece 4 for processing. The pressure plate 33 limits the workpiece, and the fastening bolts 34 pass through the pressure plate 33 and the clamping base 32 to lock the workpiece. The mounting slot 321 is provided on one side of the clamping base 32. Processing slots 322 and tool-retracting slots 323 are also provided on four planes perpendicular to one side of the mounting slot 321. The quick-clamping assembly 31 can be quickly installed and matched with the rotating flange 21, simplifying the clamping steps and making clamping more convenient and efficient. At the same time, the rotating flange 21 can drive the clamping device 3 to rotate, realizing the zero-point interchange of the four workstations, which not only improves processing efficiency but also ensures processing accuracy.

[0028] The lower end of the clamp base 32 is also provided with a threaded mounting hole 324, and the quick clamping assembly 31 is fixedly mounted to the clamp base 32 through the threaded mounting hole 324. The clamp base 32 is quickly connected to the rotating flange 21 through the quick clamping assembly 31. The processing workpiece 4 is a camera bracket fixing block. The upper surface of the processing workpiece 4 is provided with a groove 41, and the lower surface of the processing workpiece 4 is provided with two ridges 42 to be processed, and the ridges 42 are inserted into the processing groove 322. The four ends of the pressure plate 33 are provided with protrusions 331. When the processing workpiece 4 is clamped, the protrusions 331 contact the bottom surface of the groove 41, and then the pressure plate 33 is pressed by the fastening screw to clamp the processing workpiece 4.

[0029] The specific implementation of this embodiment is as follows: first, the quick-clamping assembly 31 is installed in the clamp base 32, then the workpiece 4 is installed in the four mounting grooves 321 of the clamp base 32, and then the four protrusions 331 of the pressure plate 33 are pressed respectively against the grooves 41 of the workpiece 4, and then tightened with the fastening bolts 34. After the workpiece 4 is clamped, the quick-clamping assembly 31 is quickly installed on the rotating flange 21 by engaging the locking holes 311 with the locking blocks 211.

[0030] After the clamping work is complete, the workpiece 4 is machined. During machining, the tool processes the workpiece 4 through the machining groove 322 and then retracts through the tool retraction groove 323. After retraction, the rotating flange 21 rotates the clamping device 3 to the next machining plane to process the next workpiece. This process is repeated until all workpieces 4 are machined. After all workpieces 4 are machined, the quick-clamping assembly 31 is removed from the rotating flange 21, and the next batch of workpieces 4 are replaced and the above process is repeated.

[0031] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or replacements of the present invention made by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
