Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of part machining, and particularly relates to a clamping positioning structure and a shell clamping device. BACKGROUND

[0002] Aluminum alloy has high strength and hardness, and can effectively protect the safety of internal equipment and components. Therefore, aluminum alloy material is often used to process shell parts, which need to be drilled by a numerical control machine tool.

[0003] When the shell part is processed, the side wall of the shell part is first clamped by a clamping device, and then the shell part is drilled by a numerical control machine tool. The clamping part of the clamping device abuts against the side wall of the shell part, and the clamping part is easy to scratch the side wall of the shell part during the pressing process. When the numerical control machine tool drills the shell part, drilling debris is generated, which will hinder the rotation of the drill bit of the numerical control machine tool and also affect the quality of drilling if not cleaned in time.

[0004] As disclosed in the prior art document CN202322348602.3, a thin-walled annular shell machining tool includes a base, two groups of opposite and upwardly protruding guards are arranged on the left and right ends of the base, a sliding rail is formed in the middle of each group of guards, a sliding block is slidably connected in the sliding rail, and a clamp for clamping the side or end surface of the thin-walled annular shell is detachably connected on the side where the sliding blocks on the left and right ends of the base are close to each other. The two sliding blocks on the left and right ends of the base are close to each other, and the clamp at the end of the sliding block clamps the thin-walled annular shell. This scheme clamps the thin-walled annular shell from the side and end surface, and the clamp at the end of the sliding block is easy to scratch the side wall of the shell when pressed.

[0032] Furthermore, the telescopic clamping assembly 300 includes a telescopic cylinder 310, a telescopic rod 320, and an abutment plate 330. The telescopic cylinder 310 is connected to the side of the support plate 120 away from the boss assembly 200.

The boss assembly 200 is located between the support plate 120 and the abutment plate 330. The abutment plate 330 is used to press against the housing parts on the boss assembly 200. The other end of the telescopic rod 320 abuts against the abutment plate 330. The telescopic cylinder 310 is used to drive the telescopic rod 320 to extend and retract.

[0033] In the embodiment, the shell part to be processed is quickly sleeved on the boss assembly 200, the abutting plate 330 is hung on the telescopic rod 320, the telescopic cylinder 310 is started to drive the telescopic rod 320 to contract, so that the telescopic rod 320 drives the abutting plate 330 to abut against the shell part; the shell part on the boss assembly 200 is drilled by the numerical control machine tool, the suction pump works to generate suction force in the first and second chip removal channels 201 and 1202, the drill chips fall into the first chip removal channel 201, and the drill chips are discharged outside the support plate 120 along the first and second chip removal channels 201 and 1202; after the drilling is completed, the telescopic cylinder 310 is started to drive the telescopic rod 320 to elongate, so that the telescopic rod 320 drives the abutting plate 330 to release the shell part, and the abutting plate 330 is removed after the shell part processed is removed.

[0034] The clamping and positioning structure 10 described above, the telescopic rod 320 drives the abutting plate 330 to abut against and release the shell part, so that the abutting plate 330 and the support plate 120 clamp the shell part by abutting against the two ends of the shell part, avoiding the contact between the abutting plate 330 and the side wall of the shell part, preventing the side wall of the shell part from being scratched; the drill chips sucked are discharged in time through the first and second chip removal channels 201 and 1202, reducing the influence of the drill chips on the drilling of the shell part, thereby improving the drilling quality of the numerical control machine tool on the shell part.

[0035] As shown in Figure 1 and Figure 4 , in one of the embodiments, the number of the boss assemblies 200 and the first chip removal channels 201 is multiple, the multiple boss assemblies 200 are arranged at intervals on the support plate 120, and each first chip removal channel 201 is communicated with the second chip removal channel 1202. In the embodiment, the multiple boss assemblies 200 can install multiple shell parts, so that the multiple shell parts can be drilled at the same time, thereby increasing the processing speed of the shell parts.

[0036] As shown in Figure 1 and Figure 3 , in one of the embodiments, the number of the through holes 1201, the telescopic cylinders 310, the telescopic rods 320 and the clamping grooves 3301 is multiple, each through hole 1201 is arranged between every two adjacent two boss assemblies 200, and the multiple clamping grooves 3301 are arranged at intervals on the abutting plate 330. In the embodiment, when the multiple telescopic cylinders 310 are started, the multiple telescopic cylinders 310 and the telescopic rods 320 arranged at intervals abut against the abutting plate 330, so that the abutting plate 330 is uniformly stressed, thereby making the multiple shell parts abutted by the abutting plate 330 be uniformly stressed, preventing the shell parts abutted by the abutting plate 330 from being deformed due to excessive stress.

[0037] As shown in Figure 4 and Figure 5As shown, in one of the embodiments, the second chip removal channel 1202 comprises a plurality of connecting grooves 1203 and a converging groove 1204, each of the connecting grooves 1203 is communicated with a corresponding first chip removal channel 201, and the plurality of connecting grooves 1203 are communicated with the converging groove 1204 to form the second chip removal channel 1202, and the outlet of the converging groove 1204 is used to communicate with the suction end of the suction pump. In this embodiment, the converging groove 1204 communicated by the plurality of connecting grooves 1203 makes the drilling debris uniformly converge into the converging groove 1204, and then discharged through the outlet of the converging groove 1204, which reduces the number of grooves and the number of suction ends communicated with the suction pump, thereby reducing the processing cost.

[0038] As shown, Figure 4 As shown, in one of the embodiments, the boss assembly 200 comprises a boss mounting portion 210 and a fixed connecting portion 220, both ends of the fixed connecting portion 220 are connected to the boss mounting portion 210 and the support plate 120, the boss mounting portion 210 is provided with a drilling groove 2101 and a first chip removal groove 2102, and the fixed connecting portion 220 is provided with a second chip removal groove 2201, the drilling groove 2101, the first chip removal groove 2102 and the second chip removal groove 2201 are sequentially communicated in the horizontal direction to form the first chip removal channel 201, and the second chip removal groove 2201 is communicated with the second chip removal channel 1202.
