Description
Technical Field
[0001] The utility model relates to the field of diamond cutter head installation, in particular to an anti-falling device for diamond cutter heads. Background Art
[0002] Diamond is a superhard material that acts as a cutting edge. Diamond bits are made of metal powder or metal alloy powder and are usually used to cut materials with relatively high hardness, such as granite, graphite molds, ceramics, etc.
[0003] The diamond bit will be worn during cutting, and the extended length of the worn bit will become shorter, which will gradually lead to a decrease in cutting performance. When you want to extend the bit longer, you need to disassemble the entire bit fixing part, which is very troublesome. In addition, since the bit is fixed for a long time, the fixing plate will stick together, making it inconvenient to remove the bit. Therefore, an anti-falling device for the diamond bit is proposed to solve the above problem. Utility Model Content

The extended length of the worn cutter head will become shorter, which will gradually lead to a decrease in cutting performance. When the cutter head wants to be extended longer, the entire cutter head fixing part needs to be disassembled, which is very troublesome. In addition, since the cutter head is fixed for a long time, the fixing plates will stick together, making it inconvenient to remove the cutter head.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] In the embodiment, Figure 1-4 Provided is a device for preventing diamond cutting bits from falling off. The utility model comprises a support seat 1, a lower fixing plate 2 is fixedly connected to the top of the support seat 1, two limit plates 3 are arranged on the top of the lower fixing plate 2 and are symmetrically distributed on the left and right, four springs 4 are fixedly connected to the top of the lower fixing plate 2 and are symmetrically distributed in pairs on the left and right, the tops of the four springs 4 are all in contact with an upper fixing plate 5, a rear baffle plate 7 is arranged between the upper fixing plate 5 and the lower fixing plate 2, a pushing device 8 is fixedly connected to the rear side of the lower fixing plate 2, four first bolts 6 are connected to the inner thread of the upper fixing plate 5 and are symmetrically distributed in pairs on the left and right and extend into the lower fixing plate 2 respectively, and mounting grooves are provided in the inner parts of the upper fixing plate 5 and the lower fixing plate 2.
[0028] The upper fixing plate 5 is provided with two symmetrically distributed clearance grooves corresponding to the two limiting plates 3 , and the four first bolts 6 are respectively distributed on the front and rear sides of the two clearance grooves.
[0029] The upper fixing plate 5 is placed through the stop plate 3 and the clearance groove, and the upper fixing plate 5 and the lower fixing plate 2 are kept vertically overlapped, and the first bolts 6 are used to stabilize and reinforce the two fixing plates.
[0030] When the four springs 4 are in a normal state, the total internal spacing of the two mounting grooves is greater than the length of the cutter head.
[0031] When the cutter head is placed between the two mounting grooves, the upper fixing plate 5 is pressed down by the first bolt 6 , and the spring 4 begins to be compressed. When the first bolt 6 is completely loosened, the upper fixing plate 5 will be lifted up by the compressed spring 4 .
[0032] Among them, a first sliding groove is opened inside the lower fixed plate 2, a first limiting rod 9 is fixedly connected to the bottom of the rear baffle 7, and a sliding block 10 slidably connected to the first sliding groove is fixedly connected to the bottom of the first limiting rod 9.
[0033] The slide block 10 fits into the first slide groove, so that the rear baffle 7 will not collapse or deviate, and supports the rear baffle 7 connected to the first limiting rod 9 .
[0034] A second slide groove is provided inside the upper fixing plate 5 , and a second limiting rod 11 penetrating through and extending to the outside of the upper fixing plate 5 is fixedly connected to the top of the rear baffle 7 , and the second limiting rod 11 is set in a square shape.
[0035] When the rear baffle 7 is pushed, the second limiting rod 11 also slides in the second sliding groove along with the rear baffle 7 to limit the moving direction of the rear baffle 7 .
[0036] Among them, the pushing device 8 includes an L-shaped fixing plate 81 fixedly connected to the rear side of the lower fixing plate 2, the internal thread of the L-shaped fixing plate 81 is connected to the second bolt 82, the outer side of the second bolt 82 is fixedly connected to the knob 83, and the front side of the second bolt 82 is rotatably connected to the push plate 84.
[0037] The second bolt 82 can be rotated by the knob 83, and the second bolt 82 will make the push plate 84 move forward and close to the rear baffle 7. Continuing to rotate the knob 83 can make the rear baffle 7 drive the cutter head to move forward.
[0038] Working principle:
[0039] First, place the cutter head in the installation groove of the lower fixed plate 2, and close the upper and lower fixed plates through the clearance groove. The upper fixed plate 5 will be pressed on the spring 4. At this time, the upper fixed plate 5 has no contact with the cutter head. Then, the upper and lower fixed plates are fixed by the first bolt 6. Under the action of the first bolt 6, the upper fixed plate 5 will press down the cutter head to fix it. At this time, the spring 4 enters a compressed state. Then, turn the knob 83, and the second bolt 82 will move the rear baffle 7 and fit it tightly to the rear side of the cutter head to strengthen the fixation of the cutter head. When the position of the cutter head needs to be adjusted, unscrew the four first bolts 6, and the upper fixed plate 5 can be bounced upward by the spring 4. At this time, turn the knob 83 again to push the cutter head out, and finally fix the upper fixed plate 5 again with the first bolt 6.
