[0001] The utility model belongs to the technical field of gun drilling processing, in particular to an alloy gun drilling processing device. Background Art

[0002] Gun drill is a kind of alloy gun drilling device precision deep hole processing drill, which can be used to drill very deep holes in various workpiece materials. Gun drill has a unique cutter head shape different from traditional twist drills and a chip groove running through the entire length of the tool.

[0003] In the existing gun drilling and cutting devices, the object to be cut needs to be fixed on the workbench for cutting, and these tasks often require manual operation by the staff. Since the material and shape of the object to be cut are not fixed, manual positioning cannot be accurate and fast, and the stability of the object to be cut cannot be guaranteed, which greatly reduces work efficiency. Summary of the invention

[0004] The purpose of the utility model is to provide an alloy gun drilling processing device, which is provided with gears and racks, specifically, the gears drive the racks to move, so that the movable arm moves. Because there is a fixed-point rotation of the rotating shaft, the rotating arm drives the clamping plate to move, and at the same time, the two concave clamping plates stabilize the cut object, and the cut object is positioned more accurately, which greatly reduces the time for the staff to manually adjust the cut object, greatly improves the work efficiency of the staff, and solves the problem that the gun drilling processing cutting device requires manual positioning by the staff, and the manual positioning cannot accurately and quickly perform positioning, and cannot guarantee the stability of the cut object, thus greatly reducing the work efficiency.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an alloy gun drilling processing device, including a mechanical main frame, the bottom of the mechanical main frame is fixedly connected to a base, the top of the base is fixedly connected to a workbench, the top of the workbench is provided with a fixed frame, a rack is provided inside the fixed frame, the top and bottom of the rack are slidably connected to a limiting bracket, the sides of the two limiting brackets that are away from each other are fixedly connected to the inner wall of the fixed frame, and the front and back sides of the rack are meshed with semicircular gears.

[0007] Furthermore, the parts connected to the two semicircular gears are the same. The semicircular gears are fixedly connected with a movable arm one. A movable arm two is arranged on the side of the movable arm one away from the semicircular gear, a movable arm three is arranged on the left side of the movable arm one, and a concave clamping plate is fixedly connected to the side of the movable arm three close to the movable arm one. The three movable arms are rotated at a fixed point through four rotating axes, so that the concave clamping plate can quickly and firmly clamp the object to be cut, so that the object to be cut can be stabilized on the workbench, and the cutting device can cut accurately.

[0008] Furthermore, the right side of the movable arm 1 and the right side of the movable arm 2 are fixedly connected with a rotating shaft 2, and the top and bottom of the two rotating shafts 2 are rotatably connected to the fixed frame.

[0011] Furthermore, two motors are connected to the top of the inner wall of the workbench, and the top output ends of the two motors are fixedly connected to the bottom of the motor shaft. The tops of the two motor shafts are fixedly connected with gears. When the motor is turned on, power is continuously transmitted to the rack through the motor shaft and gear, driving the movable arm and the concave splint to move, which is the main power source of this equipment.

[0012] Furthermore, the right side of the rack passes through the fixed frame and extends to the outside, the top of the motor shaft passes through the workbench and extends inside the fixed frame, the motor shaft is rotatably connected to the workbench, and the volume and shape of the object being cut are uncontrollable, so the closing distance of the two concave clamps will also change accordingly. At this time, the length of the rack's motion trajectory is needed to control it. The rack extending to the outside of the fixed frame can provide power more efficiently.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a gear and a rack, specifically, the gear drives the rack to move, so that the movable arm moves. Because the rotating shaft rotates at a fixed point, the rotating arm drives the clamping plate to move. At the same time, the two concave clamping plates stabilize the cut object and position the cut object more accurately, which greatly reduces the time for the staff to manually adjust the cut object and greatly improves the work efficiency of the staff.

[0015] 2. The utility model sets a movable arm 1, which is driven by a semicircular gear and a rotating shaft 1 to drive a movable arm 2 to move. The movable arm 2 is driven by the rotating shaft 2 to drive a movable arm 3 to move. The movable arm 3 drives a concave clamping plate to move, so that the concave clamping plate can quickly clamp the object to be cut and quickly position the object to be cut.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The front and back sides of the rack 211 are meshed and connected with a semicircular gear 212. A gear 312 and the rack 211 are provided, and specifically, the gear 312 drives the rack 211 to move, so that the movable arm 1 213 moves. Because of the fixed-point rotation of the rotating shaft 1 215, the movable arm 3 217 drives the splint 216 to move. At the same time, the two concave splints 216 stabilize the object to be cut, and more accurately position the object to be cut, which greatly reduces the time for the staff to manually adjust the object to be cut, and greatly improves the work efficiency of the staff.

[0029] The parts connected by the two semicircular gears 212 are the same. The semicircular gear 212 is fixedly connected with a movable arm 1 213. A movable arm 214 is provided on the side of the movable arm 1 213 away from the semicircular gear 212. A movable arm 3 217 is provided on the left side of the movable arm 1 213. A concave clamping plate 216 is fixedly connected to the side of the movable arm 3 217 close to the movable arm 1 213. The movable arm 1 213 is provided. The movable arm 1 213 is driven by the semicircular gear 212 and drives the movable arm 2 214 to move through the rotating shaft 1 215. The movable arm 2 214 drives the movable arm 3 217 to move under the action of the rotating shaft 2 218. The movable arm 3 217 drives the concave clamping plate 216 to move with each other, so that the concave clamping plate 216 can quickly clamp the cut object and quickly position the cut object.

[0030] The right side of the movable arm 1 213 and the right side of the movable arm 214 are both fixedly connected with a rotating shaft 218 , and the tops and bottoms of the two rotating shafts 218 are both rotatably connected to the fixed frame 2 .

[0031] The left side of the movable arm 1 213 and the left side of the movable arm 214 are both fixedly connected with the rotating shaft 1 215 . The movable arm 3 217 has two rotating holes formed inside, and the inner walls of the rotating holes are rotatably connected to the outer surface of the rotating shaft 1 215 .

[0032] A fixed bracket 115 is fixedly connected to the right side of the top of the workbench 112. There are four fixed brackets 115. The tops of the four fixed brackets 115 are in contact with the bottom of the dust shield 114. The tops of the fixed brackets 115 are threadedly connected to the fixing screws 116. The dust shield 114 is fixedly connected to the bottom fixed bracket 115 through the fixing screws 116.

[0033] Two motors 3 are connected to the top of the inner wall of the workbench 112 . The output ends of the tops of the two motors 3 are fixedly connected to the bottoms of the motor shafts 311 . The tops of the two motor shafts 311 are fixedly connected with gears 312 .

[0034] The right side of the rack 211 penetrates the fixed frame 2 and extends to the outside. The top of the motor shaft 311 penetrates the workbench 112 and extends inside the fixed frame 2. The motor shaft 311 is rotatably connected to the workbench 112.

[0035] A specific application of this embodiment is: put the object to be cut into the middle of the concave clamping plate 216 on the top of the workbench 112, and start the motor 3 to start working. At this time, the two motors 3 start working, driving the motor shaft 311 to rotate, and the rotation of the motor shaft 311 drives the top gear 312 to start rotating. Because of the limitation of the limiting bracket 219, the rack 211 moves horizontally to the left or right when it is acted upon by the force of the gear 312. The horizontal movement of the rack 211 drives the semicircular gear 212 to rotate, and the rotation of the semicircular gear 212 drives the movable arm 1 213 to move. Since the left side of the movable arm 1 213 is connected to the rotating shaft 1 215, the movement of the movable arm 1 213 will drive the movable arm 3 217 to move, and at the same time, the movable arm 3 217 will drive the movable arm 2 214 through another rotating shaft 1 215. Movement, because the right sides of movable arm 1 213 and movable arm 2 214 are rotatably connected on the fixed frame 2 through rotating shaft 218, the clamping plates 216 will move relative to each other under the action of the force of movable arm 3 217. When the two 216 are close to each other, they can clamp the object to be cut, and can quickly position the material to improve work efficiency. At this time, the cutting device above the workbench starts to work, which greatly improves the stability and accuracy of the object to be cut. At the same time, a detachable dust shield 114 is installed on the top of the fixed frame 2, and a fixing screw 116 is installed on the top of the dust shield 114. The function of the dust shield 114 is to greatly reduce the waste generated when the cutting device 111 is working and fall into the semicircular gear 212 and the gear 312 below.
