Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a multi-station fixture for precision machining of mold parts. Background Technology

[0002] The prior art patent CN213225864U discloses a multi-station fixture for precision machining of mold parts, including a first main fixture platform, a second main fixture platform disposed on one side of the first main fixture platform, a third main fixture platform disposed on the side of the second main fixture platform away from the first main fixture platform, and a partition area disposed on the side of the first main fixture platform close to the second main fixture platform. This multi-station fixture for precision machining of mold parts, by setting up a first main fixture platform, a second main fixture platform, a third main fixture platform and a base, and by setting up a clamping plate, positioning bolts, positioning pins and a mounting plate, allows the user to insert the mounting plate, which is to be welded to the mold to be clamped, into the fixing holes and positioning pins, so that the user can use the multi-station fixture for precision machining of mold parts to clamp the mold to be clamped.

[0003] The fixture has poor stability when holding parts with irregular surfaces, and the physical debris generated during the processing of the parts will fly everywhere and be difficult to collect and handle. Therefore, a multi-station fixture for precision machining of mold parts is needed to meet the usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station fixture for precision machining of mold parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station fixture for precision machining of mold parts, comprising a fixture table, a plurality of clamping seats on the fixture table, a first clamping block rotatably mounted within the plurality of clamping seats, a second clamping block rotatably mounted within the first clamping block, a placement seat fixedly mounted on the upper surface of the fixture table, baffles fixedly mounted on both sides of the fixture table, a connecting rod fixedly mounted between the plurality of clamping seats, a clamping seat position adjustment mechanism provided on the fixture table and the clamping seats, and a debris suction mechanism provided on the fixture table.

[0006] Preferably, the clamp position adjustment mechanism includes a guide groove formed on the clamp table, a gear frame is slidably installed in the guide groove, the gear frame is fixedly installed at the bottom of the clamp, and a gear is provided in the clamp table, with the gear frame and the gear meshing.

[0007] Preferably, a drive motor is fixedly installed inside the fixture table, a drive shaft is fixedly installed at the output end of the drive motor, and the gear is fixedly sleeved on the drive shaft.

[0008] Preferably, the debris suction mechanism includes suction hoods fixedly installed at both ends of the clamping table, a guide tube fixedly installed on the suction hood, the other end of the guide tube being disposed inside the clamping table, and a filter screen and a fan fixedly installed inside the clamping table.

[0009] Preferably, a partition is fixedly installed inside the fixture table, and an air guide hole is provided on one side of the outer wall of the fixture table.

[0010] Preferably, a support block is fixedly installed at the bottom of the clamp, and a roller is rotatably installed inside the support block.

[0011] The beneficial effects of the utility model are:

[0012] In this invention, the structure includes clamping seats, a first clamping block, a second clamping block, and a clamping seat position adjustment mechanism. The rotation of the drive motor drives a set of gears to move on the guide groove and move closer to each other, thereby driving multiple sets of clamping seats to move and move closer to each other to clamp and fix the parts on the placement seat. When the surface of the parts is irregular, the first clamping block will rotate inside the clamping seat, and the second clamping block will rotate inside the first clamping block, thereby increasing the contact area with the surface of the parts and improving the stability of fixing the parts.

[0013] In this invention, by setting up structures such as baffles and debris suction mechanisms, the debris generated during the processing of parts is blocked by the baffles to prevent debris from flying everywhere. When the exhaust fan is started, the material debris generated after processing is sucked into the suction hood and then enters the duct through the suction hood. It then enters the fixture table through the duct and is separated from the exhaust fan by a filter screen. The operator can open the sealing plate on the fixture table to centrally process the collected material debris. Attached Figure Description

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example:

[0020] like Figure 1-3 As shown, this embodiment provides a multi-station fixture for precision machining of mold parts, including a fixture table 1, a plurality of clamping seats 2 on the fixture table 1, a first clamping block 3 rotatably installed in the plurality of clamping seats 2, a second clamping block 4 rotatably installed in the first clamping block 3, a placement seat 5 fixedly installed on the upper surface of the fixture table 1, baffles 6 fixedly installed on both sides of the fixture table 1, a connecting rod 7 fixedly installed between the plurality of clamping seats 2, a clamping seat position adjustment mechanism 8 provided on the fixture table 1 and the clamping seats 2, and a chip suction mechanism 9 provided on the fixture table 1;

[0021] First, the part to be clamped is placed on the placement seat 5. The clamping seat position adjustment mechanism 8 drives multiple sets of clamping seats 2 to move and approach each other on the fixture table 1. The movement and approach of the clamping seats 2 will drive the first clamping block 3 and the second clamping block 4 to move and approach each other, clamping and fixing the part on the placement seat 5. When the surface of the part is irregular, the first clamping block 3 will rotate inside the clamping seat 2, and the second clamping block 4 will rotate inside the first clamping block 3, thereby increasing the contact area with the surface of the part and improving the stability of fixing the part. The debris generated during the processing of the part will be blocked by the baffle 6 to prevent the debris from flying everywhere. The processed debris will be sucked into the fixture table 1 by the debris suction mechanism 9 for collection, which facilitates the centralized processing of material debris.

[0022] In this embodiment of the utility model, specifically, the clamp position adjustment mechanism 8 includes a guide groove 81 opened on the clamp table 1, a gear frame 82 is slidably installed in the guide groove 81, the gear frame 82 is fixedly installed at the bottom of the clamp 2, and a gear 83 is provided in the clamp table 1, with the gear frame 82 and the gear 83 meshing with each other.

[0023] In order to move multiple sets of clamping seats 2 to clamp and fix the parts, the rotation of gear 83 will drive the gear frame 82 to move. A set of gear frames 82 moves on the guide groove 81 and moves closer to each other, which will drive multiple sets of clamping seats 2 to move closer to each other. The movement of clamping seats 2 and their proximity will drive the first clamping block 3 and the second clamping block 4 to move closer to each other, clamping and fixing the parts on the placement seat 5. Multiple parts can be clamped and fixed at one time.

[0024] In this embodiment of the utility model, a drive motor 84 is fixedly installed inside the fixture table 1, and a drive shaft 85 is fixedly installed at the output end of the drive motor 84, with a gear 83 fixedly sleeved on the drive shaft 85.

[0025] In order to drive gear 83 to rotate, drive motor 84 is started. The rotation of drive motor 84 will drive drive shaft 85 to rotate, and the rotation of drive shaft 85 will drive gear 83 to rotate.

[0026] In this embodiment of the utility model, specifically, the debris suction mechanism 9 includes a suction cover 91 fixedly installed at both ends of the clamping table 1, a conduit 92 fixedly installed on the suction cover 91, the other end of the conduit 92 being disposed inside the clamping table 1, and a filter screen 93 and a fan 94 fixedly installed inside the clamping table 1.

[0027] In order to collect the material debris generated after processing, the exhaust fan 94 is started. The material debris generated after processing is sucked into the suction hood 91 and then enters the conduit 92 through the suction hood 91. It then enters the fixture table 1 through the conduit 92 and is separated from the exhaust fan 94 by the filter screen 93. The operator can open the sealing plate on the fixture table 1 to centrally process the collected material debris.

[0028] In this embodiment of the utility model, a partition 95 is fixedly installed inside the fixture table 1, and an air guide hole 96 is opened on one side of the outer wall of the fixture table 1.

[0029] By setting the air guide hole 96, a ventilation structure can be formed inside the fixture table 1, which will not affect the use of the exhaust fan 94. By setting the partition 95, multiple sets of exhaust fans 94 symmetrically arranged inside the fixture table 1 can be separated so that they do not interfere with each other during operation.

[0030] In this embodiment of the utility model, a support block 10 is fixedly installed at the bottom of the clamp 2, and a roller 11 is rotatably installed inside the support block 10.

[0031] In order to reduce friction when the clamp 2 moves, the roller 11 rolls on the clamp table 1, which will drive the clamp 2 to move, thereby reducing friction when the clamp 2 moves.

[0032] Working principle: In use, place the part to be clamped on the placement seat 5, start the drive motor 84, the drive motor 84 rotates, the drive shaft 85 rotates, the drive shaft 85 rotates, the gear 83 rotates, the gear 83 rotates, and the gear frame 82 moves. A set of gear frames 82 moves on the guide groove 81 and moves closer to each other, which drives multiple sets of clamping seats 2 to move closer to each other. The movement and proximity of the clamping seats 2 drives the first clamping block 3 and the second clamping block 4 to move closer to each other, clamping and fixing the part on the placement seat 5. Multiple parts can be clamped and fixed at one time. When the surface of the part is irregular, one The first clamping block 3 rotates within the clamping seat 2, and the second clamping block 4 rotates within the first clamping block 3, thereby increasing the contact area with the surface of the part and improving the stability of fixing the part. The debris generated during the processing of the part is blocked by the baffle 6 to prevent the debris from flying everywhere. The exhaust fan 94 is started, and the material debris generated after processing is sucked into the suction hood 91 and enters the guide tube 92 through the suction hood 91. It then enters the fixture table 1 through the guide tube 92 and is separated from the exhaust fan 94 by the filter screen 93. The operator can open the sealing plate on the fixture table 1 to centrally process the collected material debris.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
