Problems solved by technology

[0002] At present, there is no special equipment for error detection when assembling the cam plate, and most of them use manual measurement and judgment, the measurement accuracy is not high and the error is large, and the measurement method has many steps and is very cumbersome, which greatly increases the labor intensity and cannot meet the existing industrial automation development.
In addition, in the case of wrong installation, it is necessary to disassemble the cam piece from the mandrel again. If it is found that the cam piece installed later has to be removed one by one, the wrong cam piece can be corrected. The operation is very troublesome, and the cam piece and the Most of the mandrels adopt interference fit, which is very inconvenient to disassemble and assemble. Repeated disassembly and assembly will easily cause wear of parts and affect mechanical properties.

Embodiment 1

[0023] Embodiment 1: see figure 1 , figure 2 , image 3 , a cam pre-installation error-proof tooling device, including an assembly tooling base plate 1, a first cam piece 2, a second cam piece 3, and a mandrel 4, and the first cam piece 2 and the second cam piece 3 are sequentially staggered on the On the mandrel 4, the assembly tool base 1 is provided with error-proof tooling parts, cam sheet detection parts, and mandrel centering parts,

[0024] The cam plate detection component includes a horizontally arranged cylinder a6, a cylinder connecting rod a7, a wrong-proof pin connecting plate 18, and connects the first wrong-proof pin 8 and the second wrong-proof pin 9. The cylinder a6 is fixedly connected to the bottom plate 1 of the assembly tool through the cylinder connection support, the pin head of the first anti-error pin 8 is in contact with the protruding part of the first cam plate 2, and the pin head of the first anti-error pin 8 The pin head is provided with a con...

Embodiment 2

[0028] Embodiment 2: the cam piece is triangular in shape, and the cross section of the groove formed by the through groove a19 and the through groove b20 of the positioning tool 5 is spline-shaped, as Figure 4 , Figure 5 As shown, other technical solutions and working principles are the same as those in Embodiment 1.

Embodiment 3

[0029] Embodiment 3: The number of cam pieces is N, and N is an integer number. The number of through slots and the number of error prevention pins on the positioning tool 5 are correspondingly set according to the specific number of cam pieces. Other technical solutions and working principles are related to the embodiment 1 is the same.

Abstract

The invention discloses a cam preassembling and mistake-proofing tooling device which comprises an assembly tooling bottom plate, first cam pieces, second cam pieces and a core shaft, wherein the first cam pieces and the second cam pieces are sequentially and alternatively arranged on the core shaft in sleeving manner, a mistake-proofing tooling component, a cam piece detection component and a core shaft strengthening component are arranged on the assembly tooling bottom plate; the cam piece detection component comprises a first mistake-proofing pin and a second mistake-proofing pin. Through grooves a matched with the first cam pieces and through grooves b matched with the second cam pieces are formed in the top of a positioning tool, and pin holes matched with the first mistake-proofing pin and the second mistake-proofing pin are formed in the side face of the positioning tool. Compared with the current tooling component, the cam preassembling and mistake-proofing tooling device has the advantages that the positioning tool is matched with the detection components, the positions, angles and spaces of cams assembled on the core shaft are detected, and the mistake-proofing purpose is achieved; the manpower and material investment of the detection process is reduced, the production cycle is greatly shortened, the product quality is improved, and the industrial automation production is facilitated.
