Description

Workpiece clamping punching device

technical field

The utility model relates to a device, in particular to a workpiece clamping and punching device.

Background technique

The biggest problem with shift fork workpieces with thin plates (as shown in Figure 8) is the troublesome processing. It is necessary to drill the round hole on the shift fork first, and then weld the formed thin plate on the shift fork, because the welding needs to pass through the welding wire The formed sheet is welded to the shift fork. When workers weld, the positional accuracy between the sheet and the shift fork is difficult to guarantee, resulting in a high rate of defective products. Moreover, the sheet has internal stress after welding, and the edge of the sheet will be partially deformed, which will also affect the Dimensional accuracy.

Utility model content

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a workpiece clamping and punching device that welds a thin plate on the shift fork in advance, and then drills the shift fork and corrects the punching of the thin plate. Demand for high-precision production.

The utility model adopts the technical solution to solve the technical problems: the workpiece clamping and punching device includes a base on which a shift fork clamping mechanism and a thin plate correction punching mechanism are fixed; the shift fork clamping mechanism includes a rest On the support block on the top surface of the base, two positioning plates arranged in the shape of "eight" are fixed on the top surface of the support block, the large openings of the two positioning plates are set in the direction of "X", and a vertical block is fixed between the two positioning plates 1. The vertical block 1 is threaded with screw 1 arranged along the "X" direction, and the outer side of the support block is provided with a fixed block fixed on the base. The fixed block is threaded with a pair of screws distributed along the "Y" direction but along the "Y" direction. The lead screw is moved in the X direction, and a pair of guide rods distributed along the "Y" direction but moved in the "X" direction are plugged into the fixed block. A plate is arranged on the outside of the fixed block, and the outer ends of the two guide rods are connected. Fixed on the board, a pair of bearings distributed along the "Y" direction are arranged on the support block, the outer ring of each bearing is fixed on the support block, and the inner ring of each bearing is respectively fixed with the corresponding screw, and the screw passes through Driven by a motor fixed on the plate; three triangular brackets are fixed on the support block, and bushes are fixed on the brackets; the thin plate correction and punching mechanism includes an upper template, a support plate is fixed on the upper template, and the bottom of the support plate The front, rear and left side are fixed with one-piece punched slices, and the lower part of the punched slices is equipped with a support table fixed on the base and matched with the size and shape of the punched slices; the upper template is fixed with guide sleeves, and the base is fixed There is a guide post matched with the guide sleeve, and the guide post is equipped with a return spring; the height of the support platform matches the height of the support block. The role of the shift fork clamping mechanism here is to fix the shift fork on the workpiece to be processed, and then use it to process the hole to be drilled on the shift fork after being fixed; The amount of punching, so that the thin plate with the margin can be welded on the shift fork first, and then the margin can be punched, which can improve the processing efficiency and precision of the shift fork workpiece with thin plate, compared with the traditional processing method ( That is, the shift fork and the thin plate are processed separately, and then the processed thin plate is directly welded on the shift fork), which not only has high efficiency, but also has high precision and low cost; Slope fit, because the two positioning plates are in the shape of "eight", so when the two positioning plates are pressed from the direction of the large opening to the small opening, the shift fork will be pressed laterally on the two positioning plates; here, vertical block 1 and screw 1 The effect is that screw one can make the screw one move from the large mouth of the two positioning plates to the small opening direction, thereby pressing the shift fork workpiece on the two positioning plates; Therefore, the hole drilled on the shift fork workpiece has higher precision. Since the bracket and the bushing are relatively higher than the top surface of the mounting block, the longitudinal installation of the shift fork workpiece will not be affected.

Further improvement, a pair of vertical blocks 2 respectively located on both sides of the vertical block 1 are fixed on the top surface of the support block, and the top of each vertical block 2 is provided with a horizontal block perpendicular to the vertical block 2, and a square hole is opened on the vertical block 2. The outer side of the bottom surface of the horizontal block is fixed with a square column plugged into the square hole. The square column is provided with a longitudinal hole connecting upwards to the outside world. There are four longitudinal holes which are evenly distributed along the center of the longitudinal hole and run through the four square columns respectively. The horizontal holes on the side, each horizontal hole is plugged with a plug-in rod, and a return spring for each plug-in rod radially approaching each other toward the longitudinal hole direction is installed on the square column. The top of the longitudinal hole is threaded, and Screws are threaded, and the bottom of the screw is fixed with a round rod coaxially arranged with the screw. Conical surface 2, the four sides of the square hole are provided with positioning holes for matching with each insertion rod; when the circular cone surface 1 presses each circular cone surface 2, each insertion rod is pressed, moved, compressed and reset The springs are stuck together at the positioning holes; the horizontal block is screwed with two longitudinally arranged screws. Here, the function of the vertical block 2, the horizontal block, and the screw 2 is to limit the longitudinal position of the shift fork on the workpiece to be processed, so as to avoid the longitudinal vibration of the shift fork when the drill bit is used to drill the hole. Higher precision; here, the horizontal block and the vertical block are detachable, which is beneficial to the longitudinal installation of the shift fork (fork workpiece) at the two positioning plates, because the horizontal block is horizontally above the shift fork workpiece , so when installing the shift fork at the two positioning plates, it is most convenient to install the shift fork vertically downward. Therefore, in order to prevent the horizontal block from blocking the longitudinal installation of the shift fork, the horizontal block is removed from the vertical block 2 first, and then the shift fork is installed on the two positioning plates. After positioning the plate, insert the square column on the horizontal block into the square hole, and then turn the screw to drive the round rod to press each insertion rod, so that each insertion rod is respectively inserted into the respective positioning hole, so that Make the horizontal block firmly fixed on the two vertical blocks (as shown in Figure 5).

As a further improvement, nuts are threaded on the first screw and the second screw. The function of the nut here is that when the screw 1 and the screw 2 are pressed against the top surface of the shift fork workpiece, the nut can be used to further fix the screw 1 and the screw 2, so as to avoid the vibration of the screw 1 when the drill bit is used to drill the hole. And screw two loose situation.

The beneficial effects of the utility model are: the structure design of the utility model is ingenious and reasonable, and the shift fork is clamped by the thin plate clamping mechanism, thereby drilling the shift fork; and then the thin plate on the workpiece is moved The mobile rests on the support table for support, and finally uses the thin plate correction punching mechanism to correct and punch the edge margin of the thin plate, so as to obtain qualified products. This method has high processing efficiency and high precision, and is worthy of popularization and application.
