Description

Technical Field

[0001] The utility model belongs to the technical field of mold processing, and particularly relates to a multi-station fixture for precision machining of mold parts. Background Art

[0002] Generally, when precision machining mold parts, tools are needed to fix and limit the parts to prevent displacement of the parts during machining by the equipment, which causes machining errors and affects the machining quality of the parts.

[0003] The existing mold parts are fixed and limited by installation on a single station. When the parts on the station are precision machined, new parts need to wait until the parts on the station are processed and disassembled before they can be fixed again and then processed. Therefore, when a large number of parts are precision machined, the single station cannot perform part machining and part fixing operations simultaneously, so the part machining efficiency is low.

[0004] Therefore, it is necessary to provide a new multi-station fixture for precision machining of mold parts to solve the above technical problems. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a multi-station fixture for precision machining of mold parts that can machine the side and inclined angles and effectively position and clamp the parts of circular or square instruments.

[0006] To solve the above technical problems, the multi-station fixture for precision machining of mold parts provided by the utility model includes: a support base, an alternating transmission mechanism is arranged on the support base, and two groups of clamping mechanisms are arranged on the support base;

[0007] The alternating transmission mechanism includes four groups of fixing frames, the four groups of fixing frames are symmetrically distributed and fixedly installed on the support base, a first screw rod is rotatably connected between every two groups of fixing frames, a gear is fixedly sleeved on the first screw rod, the two gears are meshed with each other, a servo motor is fixedly installed on the support base, the output shaft of the servo motor is fixedly connected with one end of the corresponding first screw rod, and a translation plate is threadedly sleeved on the first screw rod;

[0008] The clamping mechanism includes a fixed station, the fixed station is fixedly installed on the translation plate, a U-shaped support plate is fixedly installed on the fixed station, a fixed block is fixedly installed in the groove of the U-shaped support plate, a second screw rod penetrates through the fixed block, a hand wheel is fixedly installed at one end of the second screw rod, and two translation modules are threadedly sleeved on the second screw rod, and a clamping block is fixedly installed at the top of the translation module.

[0009] As a further solution of the utility model, a sliding block is fixedly installed on the side of the clamping block, a guide rod passes through the sliding block, and both ends of the guide rod are fixedly installed on a fixed station.

[0010] As a further solution of the utility model, a protective shell is fixedly installed on the support seat, and the two groups of gears are located in the protective shell.

[0011] As a further solution of the utility model, two groups of guide grooves are provided on the top of the support seat, and the bottom end of the translation plate is slidably disposed in the guide grooves.

[0012] As a further solution of the present invention, the thread structures at the left and right ends of the second screw are arranged oppositely, and the two groups of translation modules are symmetrically distributed at the center position of the second screw.

[0013] As a further solution of the utility model, the sides of the two groups of clamping blocks are both provided with V-shaped grooves, and the two groups of V-shaped grooves are symmetrically distributed.

[0014] Compared with the related art, the multi-station fixture for precision machining of mold parts provided by the utility model has the following beneficial effects:

[0015] The clamping block can not only clamp and fix rectangular plane parts, but also shaft parts. Secondly, when the translation plate is driven to move by two sets of gears with opposite rotation directions, the two sets of translation plates respectively drive the fixed stations to move alternately to the position of the part processing equipment. When the equipment processes the parts fixed on one set of fixed stations, the other set of fixed stations moves to the end away from the equipment to fix and limit the parts. In this way, the processing efficiency can be improved by using the double stations to move alternately to simultaneously carry out the conveying part processing and fixed installation.

[0024] The clamping mechanism includes a fixing station 3, the fixing station 3 is fixedly installed on the translation plate 204, a U-shaped support plate 301 is fixedly installed on the fixing station 3, a fixing block 302 is fixedly installed in the groove of the U-shaped support plate 301, a second screw 303 penetrates through the fixing block 302, a handwheel 304 is fixedly installed at one end of the second screw 303, two groups of translation modules 305 are threadedly sleeved on the second screw 303, and a clamping block 306 is fixedly installed at the top of the translation module 305.

[0026] By providing the guide rod 401 , the slider 4 can limit the clamping block 306 when sliding on the guide rod 401 , thereby keeping the clamping block 306 moving smoothly.

[0027] like Figure 1 As shown, a protective shell 5 is fixedly mounted on the support seat 1, and the two sets of gears 202 are both located in the protective shell 5;

[0028] By providing the protective shell 5, the protective shell 5 can cover the two sets of gears 202 to play a safety role.

[0029] like Figure 1 As shown, two sets of guide grooves are provided on the top of the support seat 1, and the bottom end of the translation plate 204 is slidably disposed in the guide grooves.

[0030] By providing the guide groove, the bottom end of the translation plate 204 can be limited and supported.

[0032] After driving the second screw rod 303 to rotate helically, the second screw rod 303 can synchronously drive the two groups of translation modules 305 to move in opposite directions, so that the translation modules 305 can drive the translation modules 305 to clamp and fix parts.

[0037] The second step: when the fixed limit installation of the part on one of the fixed stations 3 is completed, the servo motor 203 is energized to drive one group of gears 202 to rotate, and then the other group of gears 202 meshing with it is driven to rotate in the opposite direction, thereby making the two groups of first screws 201 rotate forward and reversely, and then when one of the first screws 201 drives the fixed station 3 on the translation plate 204 to move parallel to the position of the part processing equipment, the other group of first screws 201 will drive the other translation plate 204 to move away from the part processing equipment, and then the part to be processed is fixedly installed on the fixed station 3, and the operation is repeated to realize the alternating movement of the two stations, so that when the part on one station is precisely processed, the other station can fix the part to be processed, and the two are operated synchronously to improve the part processing efficiency.
