Description

Technical Field

[0001] This utility model relates to the field of tumbler machine technology, and in particular to a horizontal sanding device for a tumbler machine. Background Technology

[0002] Mobile phone mid-plates are typically produced by die casting, and the surface of die-cast mid-plates often has surface defects such as burrs / flashes. Currently, burr / flash removal machines used for mobile phone mid-plates can only clamp the mid-plate and remove burrs / flashes from either the front or back. Because many irregular structures exist around the perimeter of the mobile phone mid-plate, burr / flash removal machines are not suitable for this task, and manual removal is the only option. However, manual removal has drawbacks: the manual technique is unstable and inconsistent, which can easily lead to incomplete removal of burrs / flashes from the mid-plate, hindering quality control. Furthermore, manual removal is inefficient and requires significant physical exertion.

[0003] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a horizontal polishing device for a burr removal machine, which effectively solves the technical defect in the existing technology that the side of the mobile phone midplate cannot be burred / deburred by a burr removal machine, thereby improving the production yield and production efficiency of the mobile phone midplate.

[0005] This utility model provides a horizontal polishing device for a blasting machine, including a support fixture for clamping a mobile phone midplate, an abrasive provided on one side of the support fixture for polishing the side of the mobile phone midplate, a polishing execution mechanism for driving the abrasive to rotate, a Y-axis execution mechanism for driving the abrasive to move along the Y-axis, and an X-axis execution mechanism for driving the abrasive to move along the X-axis. The Y-axis execution mechanism is mounted on the X-axis execution mechanism, and the polishing execution mechanism is mounted on the Y-axis execution mechanism.

[0006] The beneficial effect of the horizontal polishing device for the burr machine provided by this utility model is that when performing the polishing operation of the side of the mobile phone middle plate, the mobile phone middle plate is first clamped on the support fixture, and then the X-axis actuator drives the grinding wheel to contact the position of the mobile phone middle plate that needs to be polished. Then, the polishing actuator is started to drive the grinding wheel to rotate for polishing, and the Y-axis actuator drives the grinding wheel to move along the Y-axis to polish different positions on the side of the mobile phone middle plate. Compared with existing technologies, by setting up a support fixture and using the X-axis and Y-axis actuators to move the grinding wheel horizontally to the side of the mobile phone midplate for grinding, the instability and inconsistency of manual grinding of the side of the mobile phone midplate in traditional technologies are effectively solved. This improves the effect of removing burrs / flashes from the mobile phone midplate, thereby increasing the production yield. At the same time, it can improve grinding efficiency and reduce the labor intensity of operators, making it especially suitable for mass production operations.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 6 The horizontal sanding apparatus 100 for a burr machine provided in several embodiments of this application will now be described.

[0025] The horizontal polishing device 100 of the polishing machine includes a support fixture 10, a polishing mold, a polishing actuator 20, a Y-axis actuator 30, and an X-axis actuator 40. The support fixture 10 is used to clamp the middle plate of the mobile phone. The polishing mold is located on one side of the support fixture 10 and is used to polish the side of the middle plate of the mobile phone. The polishing actuator 20 is used to drive the polishing mold to rotate to polish the middle plate of the mobile phone. The Y-axis actuator 30 is used to drive the polishing mold to move along the Y-axis to cooperate with the polishing mold to polish the middle plate of the mobile phone. The X-axis actuator 40 is used to drive the polishing mold to move along the X-axis to abut or release the abutment against the middle plate of the mobile phone. The polishing actuator 20 is installed on the Y-axis actuator 30.

[0026] Specifically, when performing side grinding operations on the mobile phone mid-plate, the mobile phone mid-plate is first clamped onto the support fixture 10. Then, the X-axis actuator 40 drives the grinding wheel to contact the position on the mobile phone mid-plate that needs grinding. Next, the grinding actuator 20 is activated to drive the grinding wheel to rotate for grinding, and the Y-axis actuator 30 drives the grinding wheel to move along the Y-axis to grind different positions on the side of the mobile phone mid-plate. Compared with the prior art, by setting up the support fixture 10 and linking the X-axis actuator 40 and the Y-axis actuator 30 to move the grinding wheel horizontally to the side of the mobile phone mid-plate for grinding operations, the instability and inconsistency of manually grinding the side of the mobile phone mid-plate in the traditional technology are effectively solved. This improves the effect of removing burrs / flashes from the mobile phone mid-plate, thereby increasing the production yield. At the same time, it can improve grinding efficiency and reduce the labor intensity of operators, which is especially suitable for mass production operations.

[0027] First Embodiment Please refer to the following: Figures 1 to 3 The first embodiment provides a specific structure for the horizontal sanding device 100 of a tumbler machine. The horizontal sanding device 100 of the tumbler machine includes a support fixture 10, a sanding tool, a sanding actuator 20, a Y-axis actuator 30, and an X-axis actuator 40.

[0028] In the first embodiment, the Y-axis actuator 30 is a rodless cylinder, which includes a first base 31, a first crossbar 32 disposed on the first base 31 and extending along the Y-axis, a first cylinder body 33 movably mounted on the first crossbar 32, and a first mounting seat 34 mounted on the first cylinder body 33; the grinding actuator 20 is fixedly mounted on the first mounting seat 34. The X-axis actuator 40 includes a first guide rail 41 extending left and right, a first slider 42 movably mounted on the first guide rail 41, an X-axis moving seat 43 fixedly mounted on the first slider 42, and an X-axis cylinder 44 for driving the X-axis moving seat 43 to move along the X-axis; the Y-axis actuator 30 is mounted on the upper surface of the X-axis moving seat 43.

[0029] It is understandable that the mold can be used to polish the middle plate of the mobile phone through the Y-axis actuator 30 and the X-axis actuator 40; that is, when the Y-axis actuator 30 drives the mold to move back and forth along the Y-axis, the X-axis actuator 40 can drive the mold to move left and right along the X-axis.

[0030] Specifically, the first guide rail 41 has two rails with a front-to-back spacing, and each first guide rail 41 can be movably mounted with a first slider 42. The front and rear ends of the X-axis moving seat 43 are installed with the two first sliders 42 one by one. The first mounting seat 34 is provided with a first clamping seat 35, which is used to clamp and fix the grinding actuator 20. The grinding actuator 20 is a worm gear brushless DC motor, which includes a motor body 21 and an output shaft 22. The output shaft 22 is set perpendicular to the motor body 21.

[0031] More specifically, the output shaft 22 extends vertically upward; the grinding tool is a steel wire wheel 23, which is fixedly installed on the output shaft 22 and placed horizontally. By setting the horizontally placed steel wire wheel 23, in conjunction with the support fixture 10 structure, the mobile phone middle plate can be installed on the support fixture 10. The X-axis actuator 40 and Y-axis actuator 30 are used to drive the steel wire wheel 23 to perform grinding operations on the side of the mobile phone middle plate, realizing fully automatic grinding operations without operator intervention, reducing the labor intensity of operators, and improving production efficiency.

[0032] In the first embodiment, there are two grinding wheels, which are spaced apart from each other, and a support fixture 10 is disposed between the two grinding wheels. Each grinding wheel is provided with a grinding actuator 20, a Y-axis actuator 30 and an X-axis actuator 40 as needed, so as to perform grinding operations in conjunction with the grinding wheel.

[0033] Second Embodiment Please refer to the following: Figures 4 to 6 The second embodiment provides a specific structure for the horizontal sanding device 100 of a tumbler. The structure of the horizontal sanding device 100 of the tumbler provided in the second embodiment is roughly the same as that of the horizontal sanding device 100 of the tumbler provided in the first embodiment, except that it also includes a vertical fine-tuning mechanism 50.

[0034] In the second embodiment, the vertical fine-tuning mechanism 50 includes a lower adjustment seat 51 fixedly mounted on the upper surface of the X-axis moving seat 43, an upper adjustment seat 52 movably mounted on the lower adjustment seat 51, and a lever 53 rotatably mounted on the lower adjustment seat 51 for moving the upper adjustment seat 52 up and down. The first base 31 is fixedly mounted on the upper adjustment seat 52 and is vertically spaced from the X-axis moving seat 43. When the lever 53 is rotated upward, it can drive the upper adjustment seat 52 to move upward relative to the lower adjustment seat 51. When the lever 53 is rotated downward, it can drive the upper adjustment seat 52 to move downward relative to the lower adjustment seat 51.

[0035] It should be noted that the upper and lower adjusting seats can only move up and down. The upper and lower adjusting seats are restricted from moving up and down by using a dovetail groove and a dovetail protrusion to cooperate with each other.

[0036] Specifically, the lower adjusting seat 51 is screwed to an adjusting screw 511; the lever 53 includes a central pivot portion 531 for pivoting onto the lower adjusting seat 51, a first actuating portion 532 integrally formed on the outside of the central pivot portion 531 for abutting against the upper adjusting seat 52, and a second actuating portion 533 integrally formed on the outside of the central pivot portion 531 for the adjusting screw 511 to abut against. The endpoints of the central pivot portion 531, the first actuating portion 532, and the second actuating portion 533 are arranged in a triangular structure. The upper adjusting seat 52 is screwed to a locking screw 521, and the lower adjusting seat 51 has a through hole 512 through which the locking screw 521 passes. When the locking screw 521 is rotated clockwise, it can lock the upper adjusting seat 52 and the lower adjusting seat 51; when the locking screw 521 is rotated counterclockwise, it can unlock the upper adjusting seat 52 and the lower adjusting seat 51. The first action part 532 has a spherical abutment part 5321 on the side that abuts against the upper adjustment seat 52. The spherical abutment part 5321 can increase the reliability and stability of the first action part 532 moving the upper adjustment seat 52 upward.

[0037] It should be noted that the central pivot is pivotally connected to the lower adjusting seat via a pivot shaft or screw.

[0038] When adjusting the vertical distance between the first base 31 and the X-axis moving seat 43, the adjusting screw 511 is rotated clockwise and pressed against the second actuating part 533. This causes the linkage lever 53 to rotate clockwise, causing the first actuating part 532 to swing clockwise upwards, driving the upper adjusting seat 52 to move upwards. Ultimately, this causes the first base 31 to move upwards relative to the X-axis moving seat 43. By rotating the adjusting screw 511 counterclockwise to retract a certain distance, the second actuating part 533 compensates for the retraction of the adjusting screw 511. This then causes the linkage lever 53 to rotate counterclockwise, causing the first actuating part 532 to swing counterclockwise downwards. Ultimately, this causes the first base 31 to move downwards relative to the X-axis moving seat 43. Each adjustment requires rotating the locking screw 521 counterclockwise to loosen the upper and lower adjusting seats 52 and then proceeding with the adjustment. After each adjustment, the locking screw 521 is rotated clockwise to lock the upper and lower adjusting seats 52 and maintain the desired position.

[0039] More specifically, the vertical fine-tuning mechanism 50 can be configured to adjust the different heights of the grinding tool according to the different thicknesses of the mobile phone mid-plate, thereby enabling the horizontal grinding device 100 to be adapted to the grinding operations of mobile phone mid-plates of different thicknesses, thus improving the versatility of the horizontal grinding device 100.

[0040] In the second embodiment, the output shaft 22 extends horizontally; the abrasive is a diamond grinding needle 24, which is fixedly installed on the output shaft 22 and faces the support fixture 10; the diamond grinding needle 24 can be used to grind small holes or grooves on the side of the mobile phone's middle plate.

[0041] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
