Description

Technical Field

[0001] The invention belongs to the technical field of pin holes for steel helmets, and in particular relates to an automatic drilling machine for police steel helmets and a use method thereof. Background Art

[0002] A police helmet, also known as a riot helmet, is a piece of personal protective equipment worn by police officers when performing specific tasks. It is usually made of high-strength materials such as steel, Kevlar or polycarbonate, which can effectively resist impact and blunt force attacks and protect the head from injury. In addition, police helmets are also equipped with masks or goggles to protect the face and eyes from splashes, smoke or chemicals. In some special cases, police helmets may also be equipped with communication equipment or night vision devices to enhance the combat capability and safety of the police.

[0003] In the prior art, when police helmets are produced, pin holes need to be made on both sides of the police helmets, and masks or buckles are installed at the positions of the pin holes. In the prior art, when the police helmets are pinned, the helmets are mostly fixed by clamps, and pin holes are made on one side and then on the other side. After the pin holes are completed, the clamp is opened to remove the helmet. This working method is inefficient. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a high-efficiency drilling machine for simultaneously drilling holes on both sides of a police helmet.

[0005] The technical solution adopted to solve the above technical problems is: an automatic drilling machine for police helmets, including a drilling platform with a through groove in the middle of the surface, a chain conveyor is arranged on the inner side of the through groove, and a helmet support structure for limiting the position of the helmet is fixedly installed on the surface of the chain conveyor.

[0006] Through the above technical solution, the drilling platform supports the entire equipment. The chain conveyor is a traditional transmission structure, which is hard and convenient for installing and fixing the helmet support structure. The helmet support structure can hold helmets with limited holes to be pinned.

[0007] The upper surface of the drilling platform is provided with two synchronous control grooves for synchronous drilling on both sides of the through groove, and the surface of the synchronous control groove is provided with a feed pin hole structure for synchronous drilling of the helmet.

[0008] Through the above technical solution, the synchronous control groove can limit the sliding of the feed pin hole structure, so that the feed pin hole structure and the helmet support structure move synchronously, and the pin hole can be drilled without stopping the chain conveyor.

[0009] A helmet squeezing locator for pressing and limiting the helmet is fixedly connected to the middle part of one side of the drilling platform surface.

[0010] Through the above technical solution, the steel helmet with the pin hole is positioned horizontally by the steel helmet support structure, and then the steel helmet with the pin hole is positioned vertically by the steel helmet extrusion locator, so as to avoid the displacement of the steel helmet during the pin hole drilling, which may cause damage to the steel helmet drilling hole, and may also cause damage to the tool of the pin hole machine.

[0011] Furthermore, two symmetrically arranged supporting lifting grooves are provided on both sides of the two synchronous control grooves, and the inner walls of the two synchronous control grooves are slidably connected with supporting columns. The supporting columns are connected to two symmetrically arranged limiting rollers through an axis, and the limiting rollers are rollingly connected to the inner walls of the supporting lifting grooves at corresponding positions. An elastic reset groove is provided on the side of the synchronous control groove away from the helmet extrusion locator, and a reset spring is fixedly connected between the inner wall of the elastic reset groove and the supporting column.

[0012] Through the above technical scheme, the support lifting groove is arranged in an arc shape near the side of the helmet extrusion locator, which is convenient for lifting the feed pin hole structure to separate it from the linkage rod, and the feed pin hole structure is automatically reset. The support column moves horizontally or upward under the action of the limiting roller and the support lifting groove, thereby achieving the purpose of controlling the horizontal movement or upward movement of the feed pin hole structure. When the feed pin hole structure moves in the horizontal direction and can move upward at the same time, the feed pin hole structure can be separated from the linkage rod, and the feed pin hole structure is reset under the action of the reset spring.

[0013] Furthermore, the helmet support structure includes a support mounting platform fixedly connected to the surface of the chain conveyor belt, a support rod platform is fixedly connected to the upper surface of the support mounting platform, an arc-shaped support outer cover is slidably connected to the outer side of the support rod platform, and two symmetrically arranged pin hole avoidance grooves are formed on the outer wall of the support outer cover near both sides of the synchronous control groove.

[0014] Through the above technical scheme, the support mounting platform supports the entire helmet support structure and is installed on the chain conveyor. The support outer cover can support and lift the helmet to be pinned. When drilling, the pin hole avoidance groove can prevent damage to the support outer cover or the tool when the pin hole machine tool penetrates the helmet.

[0015] Furthermore, a number of evenly distributed support springs are fixedly connected between the inner top wall of the support outer cover and the upper surface of the support rod platform, and a linkage rod is fixedly connected through the support mounting platform.

[0016] Through the above technical solution, the support spring will not produce rigid impact when the helmet moves to the position of the helmet extrusion locator, thereby avoiding damage to the helmet. The linkage rod can realize the synchronous movement of the feed pin hole structure and the helmet support structure.

[0017] Furthermore, the feed pin hole structure includes a transverse mounting plate fixedly connected to the top of the supporting column, an electric slide rail is fixedly connected to the middle position of the upper surface of the transverse mounting plate, a pin hole machine is fixedly installed at the slider position of the electric slide rail, a synchronous driving rod is fixedly connected to the middle of the side of the transverse mounting plate close to the helmet support structure, a mounting groove is provided on the side of the synchronous driving rod away from the helmet extrusion locator, a proximity switch is fixedly connected to the inner wall of the mounting groove, and the proximity switch and the pin hole machine are connected to the power supply through a wire to form a closed loop.

[0018] Through the above technical scheme, the transverse mounting plate can realize the support and installation of the entire feed pin hole structure, the electric slide rail can realize the feeding of the pin hole machine, and the pin holes are made on both sides of the helmet through the pin hole machine. The synchronous driving rod and the linkage rod are coordinated. The linkage rod is made of metal material. When it contacts the proximity switch, the electric slide rail can control the feeding and retracting of the pin hole machine.

[0019] Furthermore, the helmet extrusion positioner includes a guide column fixedly connected to the surface of the drilling platform, a fixed installation groove is opened below the guide column, and a plurality of evenly distributed guide wheels are rotatably connected to the inner wall of the fixed installation groove.

[0020] Through the above technical solution, installing the guide wheel in the fixed installation groove of the guide column can press the helmet in the pin hole to prevent the helmet from falling off the helmet support structure due to force.

[0021] Furthermore, the drilling platform is fixedly connected to a supporting platform at both sides of the through-groove, the inner wall of the through-groove is rotatably connected to two symmetrically arranged synchronous driving wheels at both sides of the supporting platform, and the chain conveyor is installed at the synchronous driving wheel position.

[0022] Through the above technical solution, the support platform can support the chain conveyor belt to avoid the collapse of the chain conveyor belt under the action of gravity, and the synchronous driving wheel can drive the chain conveyor belt to operate when it obtains power.

[0023] Furthermore, a power compartment is provided on the side wall of the drilling platform at a position on one side of any synchronous drive wheel, and a driving motor is fixedly connected to the bottom wall of the power compartment, and the driving end of the driving motor is fixedly connected to the rotating shaft of the corresponding synchronous drive wheel, and a power compartment dust cover is fixedly installed at the power compartment position.

[0024] Through the above technical solution, the power compartment can provide power for the synchronous drive wheels, and the dust cover in the power compartment can effectively isolate dust without affecting heat dissipation.

[0025] Furthermore, product collecting grooves penetrating the through grooves are provided at both sides of the drilling platform, and product collecting frames are provided at the positions of the product collecting grooves.

[0026] Through the above technical solution, the product collection frame arranged in the product collection groove collects the steel helmets with completed pin holes.

[0027] A method for using an automatic drilling machine for police helmets comprises the following specific steps:

[0028] S1. First, the drive motor is started, so that the chain conveyor drives the helmet support structure to operate, and the stamped helmet is placed on the helmet support structure;

[0029] S2. When the helmet support structure with the helmet placed thereon moves to the position of the helmet extrusion positioner, the helmet is pressed and fixed by the helmet extrusion positioner, and is moved to the feed pin hole structure through the chain conveyor;

[0030] S3. The steel helmet is pinned by the feed pin hole structure, and the feed pin hole structure moves with the steel helmet during the pinning process. After the drilling is completed and the tool is withdrawn, the feed pin hole structure moves back and resets, and cooperates with the steel helmet support structure moving from the rear to pin the rear helmet again;

[0031] S4. After the pin hole is completed, the helmet moves away from the helmet squeezing positioner. When the helmet support structure gradually moves downward, the helmet is separated from the helmet support structure and falls into the product collection frame.

[0032] The beneficial effects of the present invention are as follows: (1) The present invention sets a steel helmet support structure and a steel helmet squeezing positioner, and places the steel helmet directly on the steel helmet support structure, and transmits it through a chain transmission belt. When it is transmitted to the bottom of the steel helmet squeezing positioner, the steel helmet is pressed by the guide wheel, and the helmet can be fully pressed and fixed. There is no need to set up a more complicated clamping structure, which simplifies the clamping process and improves work efficiency. (2) The present invention sets a feed pin hole structure and a linkage rod. When the steel helmet is placed on the steel helmet support structure and moves with the steel helmet support structure, the linkage rod drives the feed pin hole structure to move synchronously. Therefore, pin holes can be made on both sides of the steel helmet synchronously without stopping the operation of the chain conveyor belt, which greatly improves the pinning efficiency of the steel helmet, and the linkage between the feed pin hole structure and the steel helmet support structure is higher.

[0047] A number of evenly distributed support springs 122 are fixedly connected between the inner top wall of the support outer cover 120 and the upper surface of the support rod platform 123. A linkage rod 124 is fixedly connected through the support mounting platform 125.

[0053] A method for using an automatic drilling machine for police helmets comprises the following specific steps:

[0054] S1. First, start the drive motor 5, so that the chain conveyor 11 drives the helmet support structure 12 to operate, and the stamped helmet is placed on the helmet support structure 12;

[0055] S2. When the helmet support structure 12 with the helmet placed thereon is moved to the position of the helmet extrusion positioner 8, the helmet is pressed and fixed by the extrusion positioner 8, and is moved to the feed pin hole structure 10 via the chain conveyor 11;

[0056] S3. The steel helmet is pinned by the feeding pin hole structure 10, and the feeding pin hole structure 10 moves with the steel helmet during the pinning process. After the drilling is completed and the tool is withdrawn, the feeding pin hole structure 10 moves back and resets, and cooperates with the steel helmet support structure 12 that moves from the rear to pin the rear helmet again;

[0057] S4. After the pin hole is completed, the helmet moves away from the helmet squeezing positioner 8. When the helmet support structure 12 gradually moves downward, the helmet is separated from the helmet support structure 12 and falls into the product collection frame 3.

[0058] The working principle of this embodiment is as follows: the steel helmet to be pinned is placed on the surface of the supporting outer cover 120, the position of the pin hole is aligned with the pin hole avoidance groove 121, the driving motor 5 is started, the synchronous driving wheel 13 and the chain conveyor 11 are operated, and the steel helmet support structure 12 is driven to move. When the steel helmet is moved to squeeze the position of the positioner 8, the steel helmet is buffered under the action of the support spring 122 to avoid damage to the steel helmet caused by rigid impact, and is positioned and squeezed through the guide wheel 82, and the linkage rod 124 touches the position of the synchronous driving rod 105, so that the proximity switch 103 is triggered, and the electric slide rail 102 is started, and the linkage rod 124 pushes the synchronous driving rod 105. 5, so that it moves synchronously, and the pinning machine 101 starts at the same time as the electric slide rail 102 starts, and the pinning machine 101 pins holes on both sides of the helmet. After the pinning is completed, the pinning machine 101 retracts, and after the retraction is completed, the limit roller 15 moves to the arc position of the support jacking groove 14, so that the feed pin hole structure 10 can move upward while moving in the horizontal direction, so that the linkage rod 124 is separated from the synchronous driving rod 105, and the linkage rod 124 no longer acts on the synchronous driving rod 105, so that the feed pin hole structure 10 is reset under the action of the reset tension spring 16, and then cooperates with the helmet support structure 12 moving from the rear;

[0059] After the drilling is completed, the helmet moves away from the guide wheel 82 along with the corresponding helmet support structure 12, and the helmet extrusion positioner 8 no longer acts on the helmet. When the corresponding helmet support structure 12 moves to the position of the synchronous drive wheel 13, the helmet support structure 12 tilts, and the helmet after the pin hole is completed falls off from the helmet support structure 12 and falls into the product collection frame 3.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
