Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that when using a grinding machine to finish the outer circle of the dome pin, the fixture is clamped on the outer circumference of both ends of the thimble, and the grinding wheel grinds the outer circle of the thimble, and when processing the axial middle of the thimble, the grinding wheel The extrusion force between the thimble and the thimble causes the middle part of the thimble to bend and deform, resulting in low finishing quality

Embodiment Construction

[0048] The following is attached Figure 1-3 The application is described in further detail.

[0049] A known grinding machine includes a bed, a grinding wheel and a motor. The workpiece is connected to the bed, and the motor is used to drive the grinding wheel to rotate, so as to grind the workpiece through the rotating grinding wheel.

[0050] refer to figure 1 , the embodiment of the present application discloses an auxiliary jig applied to thimble grinding, which is used to install on the bed and realize the clamping of the thimble.

[0051] refer to figure 1 , 2 , the auxiliary jig includes a bottom plate 1 , a sliding seat 2 , a clamping part 3 and an adjustment assembly 4 .

[0052] Two linear guide rails 11 are arranged side by side and horizontally on the bottom plate 1; two sliding seats 2 are provided, and each sliding seat 2 is slidably socketed on the two linear guide rails 11; There is a clamping part 3 connected in rotation, and the rotation axis of the cl...

Abstract

The invention relates to an auxiliary jig applied to thimble grinding. The auxiliary jig comprises a bottom plate, a clamp and a supporting wheel. The clamp is connected to the bottom plate and used for clamping the two ends of an ejector pin. The supporting wheel is rotationally connected with the bottom plate, and when the ejector pin is fixed to the clamp, the periphery of the supporting wheel abuts against the periphery of the ejector pin in a rolling mode. The bottom plate is installed on a grinding machine, the supporting wheel is located on the side, deviating from the grinding wheel, of the ejector pin, when the grinding wheel grinds the outer circle of the ejector pin, the supporting wheel abuts against the side, deviating from the grinding wheel, of the ejector pin in a rolling mode to bear the ejector pin, deformation of the ejector pin is reduced, and finish machining quality is improved.

Description

technical field [0001] The present application relates to the field of jigs, in particular to an auxiliary jig used in thimble grinding. Background technique [0002] When the mold is used for injection molding production, after the injection molded part is formed, due to the shape and other reasons, the injection molded part cannot automatically fall off, but stays in the cavity. For this reason, a set of ejection mechanism will be designed in the mold to eject the injection molded part out of the cavity, so as to facilitate the removal of the plastic part. [0003] Usually, the ejector mechanism includes a top plate and a plurality of ejector pins arranged on the ejector rod. When the top plate moves, the plurality of ejector pins on the top plate move synchronously, and make the ejector pins extend into the cavity to push the injection molded part out of the cavity. [0004] According to the shape, common thimbles include flat thimbles, round thimbles, etc. [0005] In ...
