Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a metal surface polishing and grinding device. Background Technology

[0002] Existing grinding equipment can only grind one side of the metal part. When grinding the other side, the workpiece needs to be loosened, then the metal part needs to be flipped over and fixed before grinding, resulting in low processing efficiency.

[0003] Existing technology CN218984343U discloses a grinding device for metal surface polishing, including a base, a support column mounted on the top of the base, connecting plates mounted on the front and rear ends of the support column, a motor mounted on the back of the connecting plates, a rotating shaft mounted on the front end of the motor, a grinding disc mounted on the front end of the rotating shaft, a bracket mounted on the top of the base, a cylinder mounted on the top of the bracket, a push rod mounted on the front end of the cylinder, and a clamping frame mounted on the front end of the push rod. This grinding device for metal surface polishing, through the L-shaped connecting plates arranged front and rear, creates a gap between the connecting plates, facilitating the accommodation of metal parts. This allows the grinding disc mounted on the front end of the connecting plates to simultaneously grind both the front and rear ends of the metal part, solving the problem in existing technologies where, when grinding the other side, the clamping structure needs to be loosened, the metal part flipped over, and clamped again before grinding the other side.

[0004] However, in actual processing, the gap between the grinding discs of the above-mentioned equipment cannot be adjusted, which means that the equipment can only grind and process metal parts of the same size, making it less practical. Utility Model Content

[0005] The purpose of this invention is to provide a metal surface polishing and grinding device, which aims to solve the problem that existing metal surface polishing and grinding devices can only grind and process metal parts of the same size, resulting in poor practicality.

[0006] To achieve the above objectives, this utility model provides a metal surface polishing and grinding device, including a base, on which a fixed bracket is welded, and an adjustment mechanism;

[0007] The adjustment mechanism includes a positioning platform, a mounting bracket, a threaded seat, an adjusting screw, a clamp, a grinding device, and a descending device. The positioning platform is fixedly connected to the base and symmetrically arranged. The mounting bracket is detachably connected to the positioning platform and located on top of the positioning platform. The threaded seat is fixedly connected to the positioning platform and symmetrically arranged. The adjusting screw is threadedly connected to the threaded seat and passes through the threaded seat, with its front stepped end abutting against the mounting bracket. The clamp is located below the fixed bracket. The grinding device is located on the mounting bracket. The descending device is located on the side of the fixed bracket near the clamp.

[0008] The grinding device includes a grinding motor and a grinding disc. The grinding motor is fixedly connected to the mounting bracket and is located on the side of the mounting bracket closer to the clamp. The grinding disc is fixedly mounted on the output shaft of the grinding motor.

[0009] The descending device includes a connecting seat and a power assembly. The connecting seat is detachably connected to the clamp and is located above the clamp. The power assembly is disposed on the side of the fixed bracket near the connecting seat.

[0010] The power assembly includes a cylinder and a guide member. The cylinder is fixed to the top of the fixed bracket, and its output end is connected to the connecting seat. The guide member is disposed on the side of the fixed bracket near the connecting seat.

[0011] The metal surface polishing and grinding equipment also includes a protective mechanism, which includes a motor cover and a tail plate. The motor cover is detachably connected to the mounting bracket and is located outside the grinding motor; the tail plate is fixed to the tail of the motor cover.

[0012] This utility model discloses a metal surface polishing and grinding device. During metal surface processing, the metal part is first fixed by a clamp. Then, the clamp is connected and installed on the descending device by connecting screws and nuts. Finally, the descending device moves the clamp downward to send the metal part to the grinding device for simultaneous grinding of both end faces. When grinding metal parts of different sizes, the tightening nut on the adjusting screw is loosened. Then, the different mating positions of the two adjusting screws and the threaded seat are adjusted to adjust the spacing between the mounting brackets, thereby adjusting the spacing between the grinding discs. This facilitates the grinding and polishing of metal parts of different sizes, thus solving the problem that existing metal surface polishing and grinding equipment can only grind metal parts of the same size, resulting in poor practicality.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of a metal surface polishing and grinding equipment. Figure 2 This is a schematic diagram of the connecting seat 110. This utility model provides a metal surface polishing and grinding device: it includes a base 101, a fixed bracket 102, and an adjustment mechanism. The adjustment mechanism includes a positioning table 103, a mounting bracket 104, a threaded seat 105, an adjusting screw 106, a clamp 107, a grinding device, and a descending device. The grinding device includes a grinding motor 108 and a grinding disc 109. The descending device includes a connecting seat 110 and a power assembly. The power assembly includes a cylinder 111 and a guide member 112. This solution solves the problem that existing metal surface polishing and grinding equipment can only grind and process metal parts of the same size, resulting in poor practicality. It can be understood that the aforementioned solution can achieve surface polishing and grinding of metal parts of multiple sizes.

[0021] In this embodiment, a fixed bracket 102 is welded onto the base 101, and the fixed bracket 102 is L-shaped.

[0022] The positioning platform 103 is fixedly connected to the base 101 and symmetrically arranged. The mounting bracket 104 is detachably connected to the positioning platform 103 and located on top of the positioning platform 103. The threaded seat 105 is fixedly connected to the positioning platform 103 and symmetrically arranged. The adjusting screw 106 is threadedly connected to the threaded seat 105 and passes through the threaded seat 105. The front stepped end can abut against the mounting bracket 104. The clamp 107 is arranged below the fixed bracket 102. The grinding device is arranged on the mounting bracket 104. The descending device is arranged on the side of the fixed bracket 102 near the clamp 107. The positioning table 103 is symmetrically installed by positioning pins and bolts. The positioning table 103 is provided with a through rectangular slide groove to facilitate the sliding of the rectangular part at the bottom of the mounting bracket 104. The threaded seat 105 is fixed by positioning pins and bolts arranged from bottom to top and is threadedly driven to engage with the adjusting screw 106. The front side of the adjusting screw 106 is a stepped round shaft end used to abut against the two end faces of the rectangular end at the bottom of the mounting bracket 104. The clamp 107 is driven to move vertically by the downward device to realize the grinding feeding and grinding and the retraction of the grinding part. The grinding device is used for grinding and polishing the surface of the metal part.

[0023] Secondly, the grinding motor 108 is fixedly connected to the mounting bracket 104 and is located on the side of the mounting bracket 104 near the clamp 107; the grinding disc 109 is fixedly mounted on the output shaft of the grinding motor 108. The grinding motor 108 is fixed by bolts, and the output shaft is connected to the end of the connecting round shaft of the grinding disc 109 through a coupling.

[0024] Then, the connecting seat 110 is detachably connected to the clamp 107 and is located above the clamp 107; the power assembly is disposed on the side of the fixed bracket 102 near the connecting seat 110. The connecting seat 110 is vertically configured with a rectangular cavity through which the top rectangular end of the clamp 107 passes. After insertion, the clamp 107 is fixed by connecting screws and nuts. The workpiece is fixed in advance, meaning that while one workpiece is being processed, the next workpiece can be fixed. During fixing, the locking screws on both sides of the clamp 107 are loosened, and then the clamp 107 is fitted onto the outside of the workpiece. The dimensions of the two end faces of the workpiece and the end face of the clamp 107 are measured with calipers to ensure that the clamp 107 is in the center of the workpiece, which is conducive to uniform grinding on both sides. At the same time, a right-angle block of the same size can be used for fixing and fitting. One side of the right-angle block is attached to the side of the workpiece to be ground, and the other side is attached to the top end face of the workpiece. At this time, the clamp 107 is pushed close to the right-angle block for fitting, and then the locking screws on both sides are tightened. The power component is used to drive the connecting seat 110 downward.

[0025] Finally, the cylinder 111 is fixed to the top of the fixed bracket 102, and its output end is connected to the connecting seat 110; the guide member 112 is disposed on the side of the fixed bracket 102 near the connecting seat 110. The cylinder 111 is fixed by bolts, and a T-shaped connecting block is screwed onto the output end of the cylinder 111. The T-shaped connecting block is connected to the connecting seat 110 by bolts. The guide member 112 includes a guide rod and a T-shaped sliding sleeve. The T-shaped sliding sleeve is fixedly connected to the fixed bracket 102. The bottom threaded end of the guide rod is connected to the threaded hole on the connecting seat 110, and the upper optical shaft end is slidably engaged with the T-shaped sliding sleeve.

[0026] When using this utility model to solve the problem that existing metal surface polishing and grinding equipment can only grind and process metal parts of the same size, resulting in poor practicality, the metal part is first fixed by the clamp 107 during metal surface processing. Then, the clamp 107 is connected and installed on the connecting seat 110 by connecting screws and nuts. Finally, the cylinder 111 drives the clamp 107 to move downwards, sending the metal part between the grinding discs 109 for simultaneous grinding of both end faces. When it is necessary to grind metal parts of different sizes, the tightening nut on the adjusting screw 106 is loosened. Then, the different mating positions of the two adjusting screws 106 and the threaded seat 105 are adjusted to achieve the spacing between the mounting brackets 104, thereby achieving the spacing adjustment between the grinding discs 109. This facilitates the grinding and polishing of metal parts of different sizes, thus solving the problem that existing metal surface polishing and grinding equipment can only grind and process metal parts of the same size, resulting in poor practicality.

Based on the first embodiment, this utility model provides a metal surface polishing and grinding equipment, which also includes a protective mechanism, including a motor cover 201 and a tail plate 202.

[0029] The motor cover 201 is detachably connected to the mounting bracket 104 and is located outside the grinding motor 108; the tail plate 202 is fixed to the tail of the motor cover 201. The motor cover 201 is fixed by bolts arranged from bottom to top, and its cross-section is a U-shaped structure with the opening facing downwards. The tail plate 202 is fixed by bolts, and the tail is provided with a ventilation port and a cable cavity.

[0030] In this embodiment, the grinding motor 108 can be protected by setting the motor cover 201, and the tail plate 202 is used for its heat dissipation and ventilation and cable arrangement.
