Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for processing long strip-shaped parts. Background Technology
[0002] Long-handled grinders are typically equipped with long handles or long grinding heads to facilitate the grinding of long workpieces. These devices can be driven by electric, pneumatic, or internal combustion engines, providing different grinding forces and speeds. They are mainly used for fine grinding and polishing of long workpieces, such as metal parts and wood products.
[0003] When using a long grinding machine to grind long parts, two clamps are needed to fix both ends of the part before grinding. However, the grinding arm of the grinding machine will squeeze the part when grinding, which will increase the fixing pressure of the clamps. Furthermore, since only one side of the two clamps has a self-locking motor to lock and fix the clamps, this may cause the clamps to drive the part to rotate, which is not convenient for precise processing of long parts. Utility Model Content
[0004] This utility model addresses the problem that when a grinding arm of a grinding machine grinds a part, it can cause pressure on the part, which increases the fixing pressure of the clamp. This may cause the clamp to rotate and make it difficult to grind long parts. Therefore, this utility model proposes a grinding device for processing long strip-shaped parts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a long strip-shaped part processing and grinding device, including a base, a housing welded to one side of the top of the base, a movable plate slidably mounted on the top of the base via a rail, clamps rotatably mounted on the sides of the housing and the movable plate adjacent to each other, an operating table provided between the housing and the movable plate, the operating table slidably mounted on the top of the rail via a rail, a lifting platform slidably mounted on the top of the operating table, a grinding arm rotatably mounted on the top of the lifting platform, and an auxiliary device provided on one side of the operating table, the auxiliary device supporting the bottom of the part by raising and lowering the auxiliary plate.
[0006] The effect achieved by the above components is that after the top of the auxiliary plate abuts against the bottom of the part, the auxiliary plate can support the part and reduce the fixing pressure of the two clamps on the part, which helps to prevent the part from rotating and thus facilitates more precise machining of the part.
[0007] Preferably, the auxiliary device includes a rectangular tube, which is fixedly installed on one side of the operating table and slidably installed on one side of the base. A lifting plate is slidably provided on the inner wall of the rectangular tube, and an auxiliary plate is slidably provided on the inner wall of the lifting plate. The auxiliary plate is located on the top of the operating table, and springs are fixedly connected to both sides of the bottom of the auxiliary plate. One end of the spring is fixedly installed on one side of the rectangular tube.
[0008] The effect achieved by the above components is as follows: when the spring is not subjected to other external forces, the spring will compress the lifting plate, causing the lifting plate to slide upward on the inner wall of the rectangular tube until the top of the auxiliary plate abuts against the bottom of the part. Then the auxiliary plate can play a role in supporting the part and reduce the fixing pressure of the two clamps on the part, which helps to prevent the part from rotating.
[0009] Preferably, a rubber sheet is adhered to the inner wall of the top of the auxiliary plate, and a plurality of grooves are evenly formed on the top of the rubber sheet.
[0010] The effect achieved by the above-mentioned components is that by setting a rubber plate with grooves to replace one side of the auxiliary plate and abut against the bottom of the part, the friction between the part and the auxiliary plate can be increased, thereby making the auxiliary plate more secure in fixing the part.
[0011] Preferably, both sides of the auxiliary plate are symmetrically fixedly connected with stop blocks.
[0012] The effect achieved by the above components is that by setting the stops, the two sides of the auxiliary plate can be blocked, which helps to prevent the auxiliary plate from being dislodged from the inner wall of the lifting plate due to accidental operation when adjusting the auxiliary plate.
[0013] Preferably, the spring has a round rod and a cylinder inside, the outer surface of the round rod is slidably disposed on the inner wall of the cylinder, and the ends of the round rod and the cylinder that are far apart are respectively fixedly installed on one side of the lifting plate and the rectangular tube.
[0014] The effect achieved by the above components is that by setting the round rod and the round cylinder, the spring can be guided and limited, which helps to prevent the spring from bending during deformation.
[0015] Preferably, the outer surface of the rectangular tube is provided with a fixing component, the fixing component including a bolt, the bolt being threaded into the top of one side of the rectangular tube.
[0016] The effect achieved by the above components is as follows: by setting bolts so that one end of the bolt passes through the inner wall of the rectangular tube until one end of the bolt abuts against one side of the lifting plate, the lifting plate and the rectangular tube can be auxiliaryly fixed, which helps to prevent the auxiliary plate that abuts against the bottom of the part from shifting.
[0017] Preferably, a threaded rod is symmetrically fixedly installed on one side of the rectangular tube, and a sleeve is slidably provided on the outer surface of the threaded rod, with one end of the sleeve fixed to the bottom of one side of the rectangular tube.
[0018] The effect achieved by the above components is that, by setting the threaded rod and the sleeve, when the lifting plate slides on the inner wall of the rectangular tube, it will drive the threaded rod to slide synchronously on the inner wall of the sleeve, thereby making the auxiliary plate more stable during the movement.
[0019] Preferably, the outer surface of the threaded rod is threaded with a nut, and the nut is located at the top of the sleeve.
[0020] The effect achieved by the above components is as follows: by setting the nut and rotating the nut so that one side of the nut abuts against one end of the sleeve, the nut can limit the direction of the threaded rod entering the sleeve, thereby further fixing the auxiliary plate and enabling the auxiliary plate to provide stable support for the parts.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting an auxiliary plate, under the action of springs on both sides, the springs can drive the top of the auxiliary plate to abut against the bottom of the part, so that the auxiliary plate can support the part and reduce the fixing pressure of the two clamps on the part, which helps to prevent the part from rotating, and thus facilitates more precise processing of the part.

[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a long strip-shaped part processing and grinding device, including a base 1. The device is characterized by: a housing 2 welded to one side of the top of the base 1; a movable plate 3 slidably mounted on the top of the base 1 via a rail; clamps 4 rotatably mounted on the sides of the housing 2 and the movable plate 3 that are close to each other; a self-locking motor and a reducer are installed inside the housing 2 to drive the clamps 3 on one side of the housing 2 to rotate and fix them; an operating platform 5 is provided between the housing 2 and the movable plate 3; the operating platform 5 is slidably mounted on the top of the rail via a rail; a lifting platform 6 is slidably mounted on the top of the operating platform 5; and a grinding arm 7 is rotatably mounted on the top of the lifting platform 6 (the grinding arm 7 can rotate on the top of the lifting platform 6, and the lifting platform 6 is generally a hydraulic lifting platform), used to drive the grinding arm 7 to move vertically; the lifting platform 6 also drives the grinding arm 7 to move horizontally on the operating platform 5, so that the grinding arm 7 can be aligned with the zero point. The workpiece is being polished. An auxiliary device 8 is provided on one side of the operating table 5. The auxiliary device 8 includes a rectangular tube 81, which is fixedly installed on one side of the operating table 5 and slidably installed on one side of the base 1. A lifting plate 82 is slidably installed on the inner wall of the rectangular tube 81, and an auxiliary plate 83 is slidably installed on the inner wall of the lifting plate 82. The auxiliary plate 83 is located on the top of the operating table 5. Springs 84 are fixedly connected to both sides of the bottom of the auxiliary plate 83. One end of the spring 84 is fixedly installed on one side of the rectangular tube 81. When there is no other external force, the spring 84 will compress the lifting plate 82, causing the lifting plate 82 to slide upward on the inner wall of the rectangular tube 81 until the top of the auxiliary plate 83 abuts against the bottom of the workpiece. The auxiliary plate 83 can then provide auxiliary support for the workpiece and reduce the fixing pressure of the two clamps 4 on the workpiece, which helps to prevent the workpiece from rotating.
[0029] Reference Figures 2-4 As shown, a rubber plate 85 is bonded to the inner wall of the top of the auxiliary plate 83. Several grooves are evenly provided on the top of the rubber plate 85. By setting the rubber plate 85 with grooves to replace one side of the auxiliary plate 83 and abut against the bottom of the part, the friction between the part and the auxiliary plate 83 can be increased, thereby making the auxiliary plate 83 more stable in fixing the part.
[0030] Reference Figures 2-4As shown, both sides of the auxiliary plate 83 are symmetrically fixedly connected with stop blocks 86. By setting the stop blocks 86, the two sides of the auxiliary plate 83 can be blocked, which helps to prevent the auxiliary plate 83 from being dislodged from the inner wall of the lifting plate 82 due to misoperation when adjusting the auxiliary plate 83. The spring 84 is provided with a round rod 88 and a cylinder 87 inside. The outer surface of the round rod 88 is slidably set on the inner wall of the cylinder 87. The ends of the round rod 88 and the cylinder 87 that are far apart are respectively fixedly installed on one side of the lifting plate 82 and the rectangular cylinder 81. By setting the round rod 88 and the cylinder 87, the spring 84 can be guided and limited, which helps to prevent the spring 84 from bending during deformation.
[0031] Reference Figure 2 and Figure 3 As shown, a fixing component 9 is provided on the outer surface of the rectangular tube 81. The fixing component 9 includes a bolt 91, which is threaded into the top of one side of the rectangular tube 81. By setting the bolt 91, one end of the bolt 91 passes through the inner wall of the rectangular tube 81 until one end of the bolt 91 abuts against one side of the lifting plate 82. This can provide auxiliary fixing between the lifting plate 82 and the rectangular tube 81, which helps to prevent the auxiliary plate 83 that abuts against the bottom of the part from shifting.
[0032] Reference Figure 2 and Figure 3 As shown, threaded rods 92 are symmetrically fixedly installed on one side of the rectangular tube 81. A sleeve 93 is slidably disposed on the outer surface of the threaded rod 92. One end of the sleeve 93 is fixed to the bottom of one side of the rectangular tube 81. By setting the threaded rod 92 and the sleeve 93, when the lifting plate 82 slides on the inner wall of the rectangular tube 81, it will drive the threaded rod 92 to slide synchronously on the inner wall of the sleeve 93, thereby making the auxiliary plate 83 more stable during movement. A nut 94 is threadedly connected to the outer surface of the threaded rod 92. The nut 94 is disposed on the top of the sleeve 93. By setting the nut 94 and rotating the nut 94, one side of the nut 94 abuts against one end of the sleeve 93. The nut 94 can limit the direction of the threaded rod 92 entering the sleeve 93, thereby further assisting in fixing the auxiliary plate 83, so that the auxiliary plate 83 can stably support the parts.
[0033] Working principle: After fixing both ends of the part with two clamps 4, rotate bolt 91 so that one end of bolt 91 moves away from rectangular tube 81. Spring 84 loses its external force restriction and resets, pressing the lifting plate 82. The lifting plate 82 slides upward on the inner wall of rectangular tube 81 until the rubber plate 85 at the top of auxiliary plate 83 abuts against the bottom of the part. Then rotate bolt 91 in the opposite direction so that one end of bolt 91 abuts against one side of lifting plate 82. Rotate nut 94 so that one side of nut 94 abuts against one end of sleeve 93. Bolt 91 can provide auxiliary fixation between lifting plate 82 and rectangular tube 81, while nut 94 can limit the direction of threaded rod 92 entering sleeve 93, thereby further assisting in fixing auxiliary plate 83. This helps prevent the auxiliary plate 83, which abuts against the bottom of the part, from shifting. Auxiliary plate 83 can provide auxiliary support for the part and reduce the fixing pressure of the two clamps 4 on the part, which helps prevent the part from rotating.
