Description

Technical Field

[0001] This utility model belongs to the technical field of polishing devices, and more specifically, it relates to a non-scratching polishing device for housing openings. Background Technology

[0002] The metal casing non-grinding polishing device is an automated finishing equipment specifically designed for precision processing of the area around the opening of aluminum or steel casings. It aims to completely remove defects such as burrs and flash, while ensuring that the processed surface is free of any visible or detectable grinding marks, scratches, or discoloration.

[0003] Based on existing technology, it has been found that existing grinding devices, after prolonged use, will grind a groove in the middle of the brush that is the same width as the metal shell. When the groove reaches a certain depth, continued use will grind a very obvious mark on the surface of the shell, resulting in substandard product quality and affecting work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a non-scratching polishing device for the opening of a housing. This solves the problem that when existing polishing devices are used, the brush thickness is greater than the tube thickness. After a long period of use, a groove of the same width as the metal housing will be ground out in the middle of the brush. When the groove reaches a certain depth, continued use will leave a very obvious mark on the outer surface of the housing, resulting in substandard product quality and affecting work efficiency.

[0005] This utility model discloses a non-abrasion-scratch polishing device for housing openings, achieved through the following specific technical means: A non-abrasion polishing device for housing openings includes a drive mechanism, an adjustment mechanism, and a fixing mechanism; The drive mechanism is provided with an adjustment mechanism; the fixing mechanism is provided on the side of the drive mechanism; The drive mechanism includes: a main body, with slide rails on both sides of the top of the main body; a proximity switch on the side of the main body; a horizontal running motor on the main body; and a screw A between the main bodies; the screw A is connected to the output shaft of the horizontal running motor. The adjusting mechanism includes: a sliding member slidably mounted on a slide rail; a guide rail provided on the sliding member; an adjusting screw provided on the sliding member; a moving member provided on the adjusting screw; the moving member slidably mounted on the guide rail; a control motor provided on the top of the moving member; a brush provided on the side of the moving member; and the brush connected to the output shaft of the control motor. The fixing mechanism includes: a support member, which is disposed on the side of the main body; and an organizer is disposed on the support member.

[0006] Furthermore, the proximity switches are provided in two sets; one set of proximity switches is located on the side of the head of the slide rail; and the other set of proximity switches is located on the side of the tail of the slide rail.

[0007] Furthermore, the drive mechanism also includes: a speed regulator A; The speed controller A is mounted on the main body; the speed controller A is mounted on the side of the horizontally running motor.

[0008] Furthermore, the adjustment mechanism also includes: a speed regulator B and a cylinder A; The speed regulator B is located on the top of the moving part; the cylinder A is located on the sliding part; and a push block is provided on the cylinder A.

[0009] Furthermore, the position of the tidying component corresponds to that of the brush; the height of the tidying component is greater than the height of the brush.

[0010] Furthermore, the fixing mechanism also includes: a fixing cylinder; The fixed cylinders are fixedly mounted on both sides of the top of the support component; each fixed cylinder is equipped with a push block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This device includes a sorting component and an adjusting screw. The sorting component is mounted on the support component, while the adjusting screw is mounted on the sliding component. By placing the square housing on top of the support component, the cylinder A extends and retracts to move it, bringing the square housing and the sorting component to the same horizontal line. The square housing is clamped and fixed by extending and retracting the fixing cylinder. Simultaneously, the horizontal running motor drives the screw A to rotate, causing the sliding component to move on the slide rail. A proximity switch detects the position of the sliding component and transmits this information to the back-end control device, which then controls the horizontal running motor to rotate forward and backward, causing the sliding component to reciprocate. The brush contacts the opening of the square housing and is rotated by a controlled motor to polish it. When the brush moves to the position of the finishing piece, it contacts the finishing piece. Since the height of the finishing piece is greater than the height of the brush, the brush can assist in polishing the finishing piece, ensuring uniform wear on all parts of the brush, avoiding grooves on the brush, and preventing scratches when polishing the opening of the square housing, thus ensuring the product's pass rate. At the same time, by manually rotating the adjusting screw, the moving part and the brush are moved closer to the opening of the square housing, thereby achieving auxiliary compensation for the wear of the brush after wear, improving the service life of the brush, extending the replacement cycle, and saving production costs.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0018] Example: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a non-scratching polishing device for the opening of a housing, including a driving mechanism 1, an adjusting mechanism 2 and a fixing mechanism 3; The drive mechanism 1 is equipped with an adjustment mechanism 2; the fixing mechanism 3 is located on the side of the drive mechanism 1. The drive mechanism 1 includes: a main body 101, with slide rails 102 on both sides of the top of the main body 101; a proximity switch 103 on the side of the main body 101; a horizontal running motor 104 on the main body 101; and a screw A105 between the main bodies 101. The screw A105 is connected to the output shaft of the horizontal running motor 104. The main body 101 is used to mount the slide rails 102, which are used to slide the sliding component 201. The proximity switch 103 mainly consists of a high-frequency oscillator, a detection coil, and a signal processing circuit. When energized, the high-frequency oscillator generates an alternating electromagnetic field through the detection coil. When a metal object (magnetic or conductive) enters this magnetic field, eddy currents are induced inside the object, causing the oscillation energy to be consumed. The approach of the object causes the oscillation amplitude of the oscillator to weaken or stop oscillating. After the signal processing circuit detects this state change, it will drive the output stage to change its state, thereby generating a switching signal. This is a mature existing technology, and its model is set as LJ12A3-4-Z / BX. It can be adjusted appropriately according to the actual working environment and is not limited. The horizontal running motor 104 is a general-purpose motor used to control the rotation of the screw A105, thereby driving the slider 201 to move on the slide rail 102. The adjusting mechanism 2 includes: a sliding member 201, which is slidably mounted on a slide rail 102; a guide rail 202 is mounted on the sliding member 201; an adjusting screw 203 is mounted on the sliding member 201; a moving member 204 is mounted on the adjusting screw 203; the moving member 204 is slidably mounted on the guide rail 202; a control motor 205 is mounted on the top of the moving member 204; a brush 207 is mounted on the side of the moving member 204; the brush 207 is connected to the output shaft of the control motor 205; the sliding member 201 is used to drive the screw 105. The sliding part 201 and the brush 207 move back and forth on the slide rail 102. The guide rail 202 is used to slide the moving part 204. The adjusting screw 203 is used to manually rotate the moving part 204 to move on the guide rail 202, so that the brush 207 can get closer to the cleaning part 302 to compensate for the wear of the brush 207. The control motor 205 is used to control the rotation of the brush 207, so that the rotation of the brush 207 can assist in polishing the surface of the housing. The fixing mechanism 3 includes: a support member 301, which is disposed on the side of the main body 101; a sorting member 302 is disposed on the support member 301; the support member 301 is used to support the square shell, and the integral member 302 is used to contact the brush 207 when it moves, thereby contacting the sorting member 302 to ensure that the brush 207 is worn evenly.

[0019] Among them, such as Figure 1As shown, there are two sets of proximity switches 103; one set of proximity switches 103 is located on the front side of the slide rail 102; the other set of proximity switches 103 is located on the rear side of the slide rail 102.

[0020] Among them, such as Figure 1 As shown, the drive mechanism 1 also includes: a speed regulator A106; the speed regulator A106 is mounted on the main body 101; the speed regulator A106 is mounted on the side of the horizontal running motor 104; the speed regulator A106 here is used to generate a square wave signal with a fixed frequency but an adjustable duty cycle (the ratio of pulse width to period) to the motor; the larger the duty cycle, the higher the average voltage and the faster the motor speed; conversely, the slower the speed. This method is highly efficient and the speed regulation is smooth. Its model is set as ZK-3D20A-0.75G, which has the same principle and model as the speed regulator B206. Different types can be replaced according to the specific load size and usage conditions, without limitation.

[0021] Among them, such as Figure 4 As shown, the adjustment mechanism 2 also includes: a speed regulator B206 and a cylinder A208; the speed regulator B206 is located on the top of the moving part 204; the cylinder A208 is located on the sliding part 201; a push block is provided on the cylinder A208; the cylinder A208 here is used to push the push block to push the square housing by telescopic movement, so as to ensure that the opening of the square housing and the sorting part 302 are on the same straight line.

[0022] Among them, such as Figure 1 As shown, the position of the tidying component 302 corresponds to that of the brush 207; the height of the tidying component 302 is greater than the height of the brush 207.

[0023] Among them, such as Figure 1 As shown, the fixing mechanism 3 also includes: a fixing cylinder 303; the fixing cylinder 303 is fixedly installed on both sides of the top of the bearing 301; a push block is provided on the fixing cylinder 303 respectively; the fixing cylinder 303 here is used to fix the square shell by extension and retraction and by contacting the two sides of the square shell with the push block, so as to ensure the stability during grinding. The grinding force of this device is not enough to deform the square shell, the clamping force is sufficient, and all the above controls are controlled by the background program.

[0024] The specific usage and function of this embodiment are as follows: In this invention, the square housing is placed on the support member 301, and the push block is driven by the cylinder A208 to push the square housing, so that the square housing and the sorting member 302 are on the same straight line. The extension and retraction of the fixing cylinder 303 causes the push block to contact the two sides of the square housing, achieving a clamping effect. The horizontal running motor 104 drives the screw A105 to rotate, causing the sliding member 201 to move on the slide rail 102. The position of the sliding member 201 can be detected by the proximity switch 103 and transmitted to the background control device, which then controls the horizontal running motor 104 to rotate forward and backward, causing the sliding member 201 to move back and forth, so that the brush 207 contacts the opening of the square housing. The motor 205 is then controlled to rotate. The rotating part polishes the surface, and when the brush 207 moves to the position of the sizing component 302, it comes into contact with the sizing component 302. Since the height of the sizing component 302 is greater than the height of the brush 207, the brush 207 can assist in polishing the sizing component 302, ensuring that all parts of the brush 207 wear evenly, avoiding grooves on the brush 207, and preventing scratches when polishing the square housing opening, thus ensuring the product's pass rate. At the same time, by manually rotating the adjusting screw 203, the moving part 204 and the brush 207 are moved closer to the square housing opening, thereby achieving auxiliary compensation for the wear of the brush 207 after wear, improving the service life of the brush 207, extending the replacement cycle, and saving production costs.
