Description

Technical Field

[0001] This utility model relates to the field of precision parts processing technology, and more specifically, to a fixing mechanism for precision parts processing. Background Technology

[0002] Precision parts are mechanical components manufactured with high precision and have extremely high requirements in terms of size, shape, and surface quality. They are widely used in the automotive industry, aerospace, electronics and information, medical devices and other fields. In order to ensure that precision parts can be accurately processed, they need to be fixed on the worktable before processing.

[0003] For example, an existing patent (publication (announcement) number: CN222831634U) discloses a clamp for placing precision parts. The clamp includes a first clamping block, a base, a fixed base, and a guide base. The bolt swings downward against the elastic force of the elastic base, thereby causing the bolt to lose its threaded connection with the clamp. Then, the bolt is pushed or pulled, which drives the clamp to move directly until the clamp contacts the precision parts. Then, the lower part of the bolt is held and the bolt is screwed upward, causing the bolt to move spirally along the clamp. The bolt acts on the clamp, and the precision parts are clamped and fixed by the clamp. Compared with conventional clamps, the clamping efficiency is improved.

[0004] However, as with the existing fixtures mentioned above, the first and second clamping blocks are both planar in structure, which is mainly suitable for precision parts with flat surfaces. For cylindrical precision parts, the contact area between the part surface and the clamping blocks is small, which affects the clamping stability of the precision parts. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fixing mechanism for precision parts processing, so as to solve the problem that the existing fixing fixtures are mainly suitable for precision parts with flat surfaces. For cylindrical precision parts, the contact area between the surface of the part and the clamping block is small, which affects the clamping stability of the fixture for the precision parts.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fixing mechanism for precision parts processing, including a fixing base, a clamping assembly on the fixing base, symmetrical first clamping blocks on the clamping assembly, fixing corner grooves on the opposite surfaces of the two first clamping blocks, a second clamping block slidably installed in the first clamping block, a plurality of fixing toothed plates evenly distributed on the second clamping block, and a switching assembly for switching the fixing corner grooves and fixing toothed plates on the first clamping block; The switching assembly includes a single-threaded screw, which is rotatably mounted on a first clamping block. A second knob is fixedly mounted on the top of the single-threaded screw. A switching frame is vertically slidably mounted on the first clamping block. The second knob is threadedly engaged with the switching frame. A slanted groove is provided at the bottom of the switching frame. First pins are fixedly mounted on both the front and rear sides of the second clamping block, and the first pins are slidably engaged in the slanted groove.

[0007] Preferably, the fixed angle groove and the fixed tooth plate are arranged alternately.

[0008] Preferably, the clamping assembly includes a double-threaded screw, which is rotatably mounted on a fixed base. Both ends of the double-threaded screw are fixedly mounted with first knobs. Symmetrical slides are threaded onto the double-threaded screw. A limit rod is fixedly mounted on the fixed base. The slides are slidably fitted onto the limit rods. The slides are fixedly connected to the first clamping blocks and correspond one-to-one.

[0009] Preferably, a chip guard is also fixedly installed on the fixed base, and the chip guard is slidably inserted into the slide base.

[0010] Preferably, there are several limiting rods, which are evenly distributed in a horizontal straight line.

[0011] Preferably, the fixed base is provided with a sieving component located below the clamping assembly, and the fixed base is also fixedly installed with a liquid collection tank located directly below the sieving component, and a discharge port is provided on one side of the liquid collection tank.

[0012] Preferably, the screening assembly includes an inner frame, an inclined filter screen is disposed inside the inner frame, a chip collection groove is fixedly installed on the front side of the inner frame, and the chip collection groove is located at the lowest end of the filter screen.

[0013] Preferably, the inner frame is vertically slidably installed in the fixed seat via a sliding foot. A motor is fixedly installed on the rear side of the fixed seat. The output end of the motor is connected to a disc. A second pin is fixedly connected to the eccentric end of the disc. A transverse groove is fixedly installed on the rear side of the inner frame. The second pin slides in cooperation with the transverse groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a double-threaded screw rotation to drive two sets of sliding blocks and a first clamping block to move closer or further apart, thereby clamping or releasing tightly fitted parts. In use, the shape of the part can be selected. By rotating the second knob, the single-threaded screw drive switching frame can slide up or down, and the inclined groove body correspondingly drives the first pin, causing the second clamping block and the fixed toothed plate to extend out of the first clamping block or retract. This allows for the selection of fixing tubular or square precision parts through the fixed corner groove or the fixed toothed plate, improving overall applicability.

[0015] This invention separates processing waste and cutting fluid through a filter screen. The waste is collected in a waste collection tank, while the cutting fluid drips into a liquid collection tank. The fluid can be sucked out by an external water pump structure connected to the outlet. During the screening process, the motor drives the disc, which in turn drives the second pin and the horizontal groove body to make the filter screen shake vertically up and down, so that the processing waste can slide down the surface of the filter screen.

[0018] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0019] As attached Figure 1 To be continued Figure 6 An embodiment of this utility model provides a fixing mechanism for precision parts processing, including a fixing base 1, a clamping assembly 2 on the fixing base 1, a symmetrical first clamping block 3 on the clamping assembly 2, a fixing corner groove 4 on the opposite surface of the two first clamping blocks 3, a second clamping block 5 slidably installed in the first clamping block 3, a plurality of fixing toothed plates 6 evenly distributed on the second clamping block 5, and a switching assembly 7 for switching the fixing corner groove 4 and the fixing toothed plates 6 on the first clamping block 3; The switching assembly 7 includes a single-threaded screw 71, which is rotatably mounted on the first clamping block 3. A second knob 72 is fixedly mounted on the top of the single-threaded screw 71. A switching frame 73 is vertically slidably mounted on the first clamping block 3. The second knob 72 is threadedly engaged with the switching frame 73. A slanted groove 74 is provided at the bottom of the switching frame 73. First pins 75 are fixedly mounted on both the front and rear sides of the second clamping block 5. The first pins 75 are slidably engaged in the slanted groove 74. The fixed angle groove 4 and the fixed toothed plate 6 are staggered. The clamping assembly 2 includes a double-threaded screw 21, which is rotatably mounted on the fixed seat 1. A first knob 22 is fixedly mounted on both ends of the double-threaded screw 21. Symmetrical slide seats 23 are threadedly mounted on the double-threaded screw 21. A limit rod 24 is fixedly mounted on the fixed seat 1. The slide seats 23 are slidably fitted onto the limit rod 24. The slide seats 23 are fixedly connected to the first clamping block 3 and correspond one-to-one.

[0020] Specifically, by rotating the double-threaded screw 21, the two sets of slide blocks 23 and the first clamping block 3 can move closer or further apart, thereby clamping or releasing tightly fitted parts. In use, the shape of the part can be selected. By rotating the second knob 72, the single-threaded screw 71 can slide the transmission switching frame 73 up or down. The inclined groove body 74 drives the first pin 75 accordingly, so that the second clamping block 5 and the fixed toothed plate 6 extend out of the first clamping block 3 or retract. Thus, the tubular or square precision parts can be fixed by the fixed corner groove 4 or the fixed toothed plate 6, thereby improving the overall applicability.

[0021] Preferably, a chip guard 25 is also fixedly installed on the fixed base 1. The chip guard 25 is slidably inserted into the slide 23. The chip guard 25 protects the double-threaded screw 21 and prevents waste chips from entering between the double-threaded screw 21 and the slide 23 and damaging the threads.

[0022] Preferably, there are several limiting rods 24, which are evenly distributed in a horizontal straight line. The limiting rods 24 can play a role in supporting the precision parts, making it easier to process them.

[0023] Furthermore, a sieving assembly 8 is provided on the fixed base 1 below the clamping assembly 2. A liquid collection tank 9 is also fixedly installed on the fixed base 1 directly below the sieving assembly 8. A discharge port 10 is provided on one side of the liquid collection tank 9. The sieving assembly 8 includes an inner frame 81. An inclined filter screen 82 is provided inside the inner frame 81. A chip collection trough 83 is fixedly installed on the front side of the inner frame 81, and the chip collection trough 83 is located at the lowest end of the filter screen 82. The inner frame 81 is vertically slidably installed in the fixed base 1 by a sliding foot 84. A motor 85 is fixedly installed on the rear side of the fixed base 1. A disc 86 is connected to the output end of the motor 85. A second pin 87 is fixedly connected to the eccentric end of the disc 86. A transverse groove 88 is fixedly installed on the rear side of the inner frame 81. The second pin 87 and the transverse groove 88 are slidably engaged.

[0024] Specifically, the filter screen 82 can separate the waste chips and cutting fluid generated during processing. The waste chips are collected in the chip collection tank 83, while the cutting fluid drips into the liquid collection tank 9. It can be sucked out by the external water pump structure of the discharge port 10. During the screening process, the motor 85 drives the disc 86, which causes the second pin 87 and the horizontal groove body 88 to work together to drive the filter screen 82 to shake vertically up and down, so that the processing waste chips can slide down the surface of the filter screen 82.
