Description

Technical Field

[0001] The utility model relates to the technical field of shell burr cleaning, in particular to a charger shell surface deburring device. Background Art

[0002] During the production and processing of the charger, its shell is an important component with protection and installation functions. The shell of the charger is usually made of injection molding or extrusion, and is mostly rectangular in shape. During the production period, there are some burrs or protrusions on the surface of the charger, which affects the subsequent assembly and use. For this reason, we propose a shell surface deburring device for charger processing.

[0003] The Chinese patent "A charger shell deburring device for electronic equipment manufacturing" authorization announcement number "CN220260468 U" places the charger shell into the inside of the snap-fit ​​placement groove, and cooperates with the trapezoidal hollow elastic soft strip to compress and deform the external extrusion, and at the same time cooperates with the fixed deformed soft plate to limit the position of the laminated deformed soft plate, and at the same time cooperates with the hollow elastic soft strip to deform the external extrusion. Shells of different shapes can be laminated to increase the contact area, and then the bonding strength between the shell surface is increased by the bonding speaker soft head on the outer surface of the bonding soft block.

[0004] The above application can realize the grinding operation of the charger, but only one surface of the charger can be grinded each time. When grinding multiple surfaces of the charger, the position of the charger needs to be adjusted multiple times, which is relatively cumbersome.

[0005] Therefore, a charger housing surface deburring device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a charger shell surface deburring device in order to solve the above-mentioned problem, thereby improving the problem that only one surface of the charger can be polished each time.

Under the action of the connecting rod and the rack, the gear drives the cam to rotate, and under the action of the cam and the spring, the first mounting plate drives the sandpaper and the two second mounting plates drive the corresponding sandpaper to reciprocate when grinding the charger shell, thereby improving the grinding effect of the charger shell.

[0010] Preferably, a spring is fixedly connected between one side of the connecting plate and the inner wall of the movable plate.

[0011] Preferably, the surface of the first mounting plate is slidably connected to two U-shaped blocks, and the surface of the second mounting plate is fixedly connected to the inner wall of the corresponding U-shaped block.

[0016] 1. When grinding the burrs on the charger shell, place the charger shell on the placement plate, rotate the bidirectional screw rod, and move the two second mounting plates to contact the charger shell at the same time, which is conducive to ensuring that the charger shell is in the center position.

DETAILED DESCRIPTION

[0024] 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.

[0025] When implementing: Figure 1-5 As shown, a charger shell surface deburring device comprises: an operating table 1, an electric push rod 2 is fixedly connected to the middle of the top of the operating table 1, a placement plate 3 is fixedly connected to the telescopic end of the electric push rod 2, and a grinding mechanism 4 is arranged on the top of the operating table 1; wherein, the grinding mechanism 4 comprises two fixed plates 401 respectively fixedly connected to the two sides of the top of the operating table 1, a movable plate 402 is slidably connected between the opposite sides of the two fixed plates 401, a connecting plate 403 is slidably connected to the bottom end of the movable plate 402, a first mounting plate 404 is fixedly connected to the bottom end of the connecting plate 403, two second mounting plates 405 are slidably connected to the bottom end of the first mounting plate 404, a grinding sandpaper 406 is fixedly connected to the bottom end of the first mounting plate 404 and one side of the two second mounting plates 405, and a grinding assembly 407 is arranged on the top of the operating table 1.

[0026] When the charger shell needs to be polished, the charger shell is placed on the placement plate 3, and the electric push rod 2 is started to push the charger shell upward so that the top of the charger shell fits with the polishing sandpaper 406 at the bottom of the first mounting plate 404. The electric push rod 2 is a relatively mature device in the prior art.

[0027] like Figure 2 and Figure 3As shown, the grinding assembly 407 includes a bidirectional screw rod 4071 rotatably connected to the inner wall of the operating table 1, and the surface of the bidirectional screw rod 4071 is threadedly connected with two movable plates 4072. The top of the movable plate 4072 passes through the operating table 1 and is fixedly connected to a mounting frame 4073. The inner wall of the mounting frame 4073 is slidably connected with a slider 4074, and one side of the two sliders 4074 is fixedly connected to the other side of the corresponding second mounting plate 405.

[0028] The threads of the two movable plates 4072 connected to the bidirectional screw rod 4071 are opposite. When the bidirectional screw rod 4071 is rotated, the two movable plates 4072 are driven to approach each other, so that the two mounting frames 4073 push the two second mounting plates 405 to approach each other through the slider 4074, so that the grinding sandpaper 406 on one side of the two second mounting plates 405 fits with the side of the charger shell, completing the limiting of the charger shell.

[0029] The movable plate 402 can be pulled to move by the handle 408, thereby driving the first mounting plate 404 and the second mounting plate 405 to move, so that the sandpaper 406 at the bottom of the first mounting plate 404 and the sandpaper 406 on one side of the two second mounting plates 405 can simultaneously grind the three surfaces of the charger housing.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, a connecting rod 4075 is slidably connected to the inner wall of one of the fixed plates 401, a rack 4076 is fixedly connected to one side of one of the fixed plates 401, a gear 4077 is meshedly connected to the surface of the rack 4076, one end of the gear 4077 is rotatably connected to one end of the connecting rod 4075, a cam 4078 is fixedly connected to the other end of the gear 4077, a trigger plate 40710 is fixedly connected to one end of the first mounting plate 404, and the surface of the cam 4078 is in contact with one side of the trigger plate 40710. A spring 4079 is fixedly connected between one side of the connecting plate 403 and the inner wall of the movable plate 402.

[0031] When the movable plate 402 moves, the connecting rod 4075 will drive the gear 4077 and the cam 4078 to move synchronously. At this time, the cam 4078 and the trigger plate 40710 move at the same speed. When the gear 4077 moves, under the action of the rack 4076, the gear 4077 will rotate, thereby driving the cam 4078 to rotate. When the cam 4078 rotates from the highest point to the lowest point and contacts the trigger plate 40710, it will push the trigger plate 40710 to move, and the spring 4079 will squeeze. When the cam 4078 rotates from the highest point to the lowest end and contacts the trigger plate 40710, the spring 4079 and the trigger plate 40710 are reset. Therefore, under the action of the cam 4078 and the spring 4079, the trigger plate 40710 will drive the first mounting plate 404 and the two second mounting plates 405 to reciprocate.

[0032] like Figure 3 As shown, two U-shaped blocks 4041 are slidably connected to the surface of the first mounting plate 404, and the surface of the second mounting plate 405 is fixedly connected to the inner wall of the corresponding U-shaped block 4041. Moving grooves are provided on both sides of the first mounting plate 404, and the two ends of the U-shaped block 4041 are slidably connected to the corresponding moving grooves.

[0033] like Figure 5 As shown, a handle 408 is fixedly connected to the top of the movable plate 402. A contact block distributed in an arc shape is fixedly connected to the surface of the handle 408, and the contact block is a rubber member. The shape of the handle 408 is an inverted "U" shape, and the center point of the handle 408 is on the same vertical plane as the center point of the movable plate 402.

[0034] like Figure 2 As shown, one end of the bidirectional screw rod 4071 passes through the operating table 1 and is fixedly connected to a knob. The surface of the knob is provided with grooves distributed in a ring shape to increase the rotation friction.

[0035] When the utility model is in use, when it is necessary to polish the charger shell, the charger shell is placed on the placement plate 3, and the electric push rod 2 is started to push the charger shell upward, so that the top of the charger shell fits with the grinding sandpaper 406 at the bottom of the first mounting plate 404. At this time, the two-way screw rod 4071 is rotated to drive the two movable plates 4072 to approach each other, so that the two mounting frames 4073 push the two second mounting plates 405 to approach each other, so that the grinding sandpaper 406 on one side of the two second mounting plates 405 fits with the side of the charger shell, thereby completing the limiting of the charger shell. At this time, the movable plate 402 is pulled by the handle 408 to move, thereby driving the first mounting plate 404 and the second mounting plate 405 to move, so that the first mounting plate 404 and the second mounting plate 405 can be moved. The sandpaper 406 at the bottom of the plate 404 and the sandpaper 406 on one side of the two second mounting plates 405 simultaneously grind the three surfaces of the charger shell. At the same time, when the movable plate 402 moves, the cam 4078 is driven to rotate under the action of the connecting rod 4075, the gear 4077, and the rack 4076, and the trigger plate 40710 drives the first mounting plate 404 and the two second mounting plates 405 to reciprocate under the action of the spring 4079, so that the sandpaper 406 reciprocates when grinding the charger shell. After completing this operation, turn over the charger shell so that the other three surfaces of the charger shell are placed between the first mounting plate 404 and the two second mounting plates 405, and repeat the above operation.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
