Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a rapid positioning fixture for a spark machine. Background Technique

[0002] A spark machine is a kind of machining equipment, mainly used for electric discharge machining, and is widely used in the manufacturing of various metal molds and mechanical equipment. It is a special machining method that uses the electro-erosion effect generated by pulsed discharge between two poles immersed in the working fluid to erode conductive materials, also known as electrical discharge machining or electro-erosion machining.

[0003] When machining parts of an injection mold by EDM, the existing machining method is to use a vise to clamp the parts, and then calibrate the table and find the center. The practicability is low, and the parts cannot be respectively installed on the rapid positioning fixture according to the different requirements of the shapes of the mold parts, which is time-consuming and laborious, and at the same time, the machining efficiency is low. For this reason, we propose a rapid positioning fixture for a spark machine. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects, and provide a rapid positioning fixture for a spark machine, which can install parts on the fixture body according to the different requirements of the shapes of the mold parts, so as to achieve the purpose of rapid positioning of various parts, without the need for frequent calibration of the table and finding the center, greatly improving the machining efficiency, and effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rapid positioning fixture for a spark machine, including a first fixture base plate, a second fixture base plate, a third fixture base plate and a fixture body;

The upper ends of the second fixture base plates are all threadedly connected with the third fixture base plates through connecting bolts. Convex plates are fixedly installed at the outer ends of the third fixture base plates. A fixture body is fixedly connected between the two second fixture base plates. Moving mechanisms are symmetrically arranged on the upper sides of the front and rear ends of the fixture body. A limiting mechanism is arranged between the upper parts of the moving mechanisms. A pressing mechanism is arranged between the inner sides of the moving mechanisms.

[0007] The limiting mechanism includes sliders, connecting blocks and limiting plates. Guide rails are evenly fixedly installed above the front and rear ends of the fixture body.

A limiting plate is arranged between the connecting blocks. The connecting blocks are threadedly connected with the limiting plate through mounting bolts. The lower end of the limiting plate is slidably connected with the chute on the fixture body through the slider.

[0008] When the parts need to be fixed, place the parts on the upper end of the jig body. The slider moves on the guide rail, and then drives the limit plate to move inward to fix and limit the left and right ends of the parts. The connecting block is threadedly connected to the limit plate, which is convenient for replacing the limit plate according to the height of the parts. Through the setting of the limiting mechanism, the parts can be installed on the jig body according to the different requirements of the shapes of the die parts, so as to achieve the purpose of quickly positioning a variety of parts, without the need for frequent dial indicator centering, which greatly improves the processing efficiency.

[0009] Further, rubber pads are fixedly connected to the inner sides of the limit plates, and anti-slip lines are evenly arranged on the rubber pads.

[0010] The setting of the rubber pads can prevent the limit plates from damaging the parts when fixing and limiting the parts, and the anti-slip lines can increase the friction force to prevent the parts from moving.

[0011] Further, the moving mechanism includes a mounting seat, a cylinder and a moving plate. Moving plates are fixedly connected to the lower ends of the sliders. The moving plates are fixedly connected to the output shafts of the cylinders. The cylinders are fixedly installed on the jig body through the mounting seats.

[0012] The cylinders drive the sliders to move back and forth on the guide rails, providing the power conditions for the limit plates to fix and limit the left and right ends of the parts.

[0013] Further, positioning grooves are evenly arranged on the upper end of the jig body. Positioning pins are inserted into the positioning grooves on the front and rear sides of the upper end of the jig body, and thickness positioning blocks are sleeved on the positioning pins.

[0014] Through the setting of the positioning pins and the thickness positioning blocks, according to the different requirements of the shapes of the die parts, the parts can be placed on the jig. By adjusting the positioning pins and the thickness positioning blocks on the positioning grooves, the purpose of quickly positioning a variety of length parts can be achieved, without the need for dial indicator centering, thus greatly improving the processing efficiency.

A sliding frame is fixedly connected to the inner side of the connecting plate. The sliding frame is slidably connected to the guide rail. Hydraulic cylinders are symmetrically installed on the lower sides of the upper ends of the sliding frame. The output shafts of the hydraulic cylinders are fixedly connected to the pressing plate. The hydraulic pump input ends of the hydraulic cylinders are electrically connected to the output ends of an external controller.

[0016] The hydraulic cylinders drive the pressing plate to move downward, and then the pressing plate presses and fixes the parts. Through the setting of the pressing mechanism, the parts can be pressed and fixed, without the need to use a vise to clamp the parts, which saves time and effort and can improve the processing efficiency.

[0017] Furthermore, convex plates are fixedly connected to the outer ends of the third fixture base plate. Thread grooves are provided in the middle of the upper ends of the convex plates, and grooves are provided at both outer ends of the convex plates.
