Example Embodiment

[0013] Such as figure 1 As shown, the clamp for machining the outer circle of the commutator includes a cylinder 1, a tie rod 2, a positioning mandrel 3, and a positioning block 4. The tie rod 2 is connected to the cylinder 1 by a thread, and the tie rod 2 is located In the positioning mandrel 3, the tail of the pull rod 2 is arranged in an I-shaped groove 5 structure, and the positioning block 4 is placed in the groove 5. When processing the commutator, sleeve the inner hole of the commutator on the head of the positioning mandrel 3, and then place the positioning block 4 into the I-shaped groove 5 of the tie rod 2 according to the correct method, the tie rod 2 The pulling force of the cylinder 1 pulls the positioning block 4 tightly, thereby positioning the commutator. The positioning mandrel 3 in this embodiment is composed of a sleeve 6 and a core rod 7, and the sleeve 6 and the core rod 7 are connected in a threaded manner. With this structure, assembly and disassembly ar...

Abstract

The invention discloses a fixture for machining an outer circle of a commutator. The fixture for machining the outer circle of the commutator is characterized by comprising an air cylinder (1), a pull rod (2), a positioning mandrel and a positioning block (4), wherein the pull rod (2) is connected with the air cylinder, the pull rod is arranged in the positioning mandrel, the tail portion of the pull rod (2) is arranged to be of an I-shaped groove structure, and the positioning block (4) is placed in a groove. According to the fixture for machining the outer circle of the commutator, the head portion of the positioning mandrel (3) is arranged in an inner hole of the commutator in a sleeved mode, the positioning block (4) is placed in the I-shaped groove of the pull rod (2), the pull rod (2) tensions the positioning block (4) under the action of tension of the air cylinder (1), and thus positioning of the commutator is carried out. By the adoption of the mode, turning can be directly carried out on the outer circle and the end face of the commutator, and the purpose of one-time forming is achieved. Meanwhile, repeated positioning errors of repeated machining of commutator products are reduced, and machining efficiency of the products can be effectively improved.

Description

technical field [0001] The patent of the present invention relates to an improved invention of a jig for processing the outer circle of a commutator. Background technique [0002] In the existing technology, there are the following three common positioning methods for machining the outer circle of the commutator. The first one is to turn the outer circle of the commutator on the instrument lathe through a thimble first, and then turn the end face or inner circle of the commutator whose outer circle has been turned through another instrument lathe after turning. This technical method has cumbersome procedures and many repeated product positioning times, which increases the positioning error of the product during processing, and the product processing efficiency is low. In the second case, the tail of the mandrel is positioned with a threaded connection nut. Although this method has high production efficiency, the number of times the employee operates the nut with a wrench is...
