Description

Technical Field

[0001] This utility model relates to the field of rock drilling tool manufacturing, and in particular to a novel hot-mounted drill bit insert injector. Background Technology

[0002] The drill bit is the main drill bit that comes into contact with the rock. It not only impacts the rock but also grinds it at high speed, causing the rock to shatter and fall off, thus completing the drilling. Therefore, the drill bit is crucial.

[0003] How to insert the alloy teeth into the drill bit when the drill bit temperature is around 500℃ is an urgent problem to be solved. Furthermore, due to the special structure of the drill bit, some alloy teeth are positioned at a certain angle. In addition, if the teeth cannot be inserted before the drill bit temperature drops, it will affect the quality of the drill bit. These problems greatly increase the difficulty of inserting the teeth.

[0004] Therefore, it is necessary to provide a novel hot-insertion tip injector to solve the above-mentioned technical problems. Utility Model Content

[0024] First Embodiment

[0025] Please refer to the following: Figure 1 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a novel heat-fitted drill bit injector provided by this utility model. A novel heat-fitted drill bit injector includes: a tooth-loading cylinder 1;

[0026] A cone cylinder 2 is fixedly installed on one side of the outer surface of the gear cylinder 1. A connecting hole 4 is provided in the middle of one side of the cone cylinder 2, and a slot 3 is provided in the middle of one side of the gear cylinder 1. A threaded groove 5 is provided on one side inside the slot 3.

[0027] A screw cap 6 is threaded onto the surface of the slot 3. An upper rod 7 is slidably mounted inside the screw cap 6, and a middle slider 8 is fixedly connected to one end of the upper rod 7.

[0028] The lower rod 9 is fixedly connected to the middle of one side of the slider 8. A spring 10 is sleeved on one side of the outer surface of the lower rod 9, and a push tooth slider 13 is fixedly connected to one end of the lower rod 9.

[0029] A magnet ring 12 is fixedly connected to one side of the outer surface of the cone 2.

[0030] One end of the spring 10 is fixedly connected to the surface of the intermediate slider 8, and the other end of the spring 10 is fixedly connected to the surface of the inner wall of the slot 3.

[0031] The diameter of the lower rod 9 is smaller than the diameter of the connecting hole 4.

[0032] The other end of the upper rod 7 is fixedly connected to a pressure cap 11.

[0033] The restoring force of the spring 10 pushes the middle slider 8 to move to the right, so that the pusher slider 13 is inside the connecting hole 4.

[0034] The connecting hole 4 and the slot 3 are connected.

[0035] The working principle of the novel heat-inserting drill bit injector provided by this utility model is as follows:

[0036] During operation, first hold the tooth-loading cylinder 1 with one hand, and place an alloy tooth into the connecting hole 4 inside the cone cylinder 2 with the other hand, exposing about 1 / 4 of the bottom of the alloy tooth to facilitate alignment during tooth insertion. After installing the alloy tooth, align the exposed 1 / 4 of the alloy tooth with the tooth hole on the drill bit, and then press the pressure cap 11 firmly. The pressure cap 11 drives the upper rod 7, the middle slider 8, the lower rod 9, and the tooth-pushing slider 13 to move, pressing the alloy tooth into the tooth hole. Then, use a copper hammer to gently tap the alloy tooth to make it fit more snugly into the drill bit to complete the tooth insertion.

[0037] Compared with related technologies, the novel hot-mounted drill bit injector provided by this utility model has the following beneficial effects:

[0038] This utility model provides a novel hot-mounting drill bit inserter. By using the inserter, not only is the inserting speed increased, ensuring all inserts are completed before the temperature drops, but safety is also improved to prevent burns. Simultaneously, inserting precision is guaranteed, drill bit quality is improved, and the lifespan of the drill bit in actual use is increased, while costs are saved. A spring 10 automatically resets the inserter, and a magnet is used to hold the alloy teeth in place, preventing them from falling out during insertion. The structure is simple and practical.

[0039] Second Embodiment

[0040] Please refer to the following: Figure 2 and Figure 3 Based on the novel heat-fitted drill bit injector provided in the first embodiment of this application, the second embodiment of this application proposes another novel heat-fitted drill bit injector. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0041] Specifically, the second embodiment of this application provides a novel hot-fitting drill bit injector, which differs in that the top of the tooth-loading cylinder 1 has a groove 20 in the middle, a driving device 14 is provided on the top of the outer surface of the tooth-loading cylinder 1, a threaded block 15 is threaded on the outer surface of the driving device 14, an electrical control box 16 is fixedly installed on one side of the outer surface of the tooth-loading cylinder 1, an extension rod 17 is fixedly installed on one side of the bottom of the electrical control box 16, a control panel 18 is fixedly installed on the surface of the extension rod 17, and a control switch 19 is provided on the surface of the control panel 18.

[0042] The drive device 14 includes a mounting block 141, a threaded rod 142, and a servo motor 143. The two mounting blocks 141 are fixedly mounted on both sides of the top of the gear cylinder 1, the threaded rod 142 is rotatably mounted between the two mounting blocks 141, and the servo motor 143 is fixedly mounted on one side of the surface of one of the mounting blocks 141.

[0043] The slide 20 is connected to the interior of the slot 3, and the threaded block 15 and the intermediate slider 8 are fixedly connected.

[0044] The working principle of the novel heat-inserting drill bit injector provided by this utility model is as follows:

[0045] During operation, the extension rod 17 is held and the output shaft of the servo motor 143 is rotated by the control panel 18 and the control switch 19. The rotation of the output shaft of the servo motor 143 drives the threaded rod 142 to rotate. The threaded rod 142 engages with the threaded block 15, which drives the intermediate slider 8 to slide back and forth. The pusher slider 13 is remotely controlled to push the alloy teeth.

[0046] Compared with related technologies, the novel hot-mounted drill bit injector provided by this utility model has the following beneficial effects:

[0047] This invention provides a novel heat-inserting drill bit injector. The output shaft of a servo motor 143 is rotated via a handheld extension rod 17, control panel 18, and control switch 19. The rotation of the servo motor 143's output shaft drives a threaded rod 142 to rotate. The threaded rod 142 engages with a threaded block 15, causing the intermediate slider 8 to slide back and forth. This enables remote control of the pusher slider 13 to push the alloy teeth. The device has a simple structure and strong practicality. Operators can install alloy teeth from a distance from the tooth hole, avoiding the impact of high temperatures on operators and improving their installation comfort.
