Description

Technical Field

[0001] This utility model relates to the field of steel plate processing, and in particular to an auxiliary tooling for CNC steel plate chamfering. Background Technology

[0002] Rail-mounted cranes are rotating cranes that travel on tracks laid along the ground and need to be disassembled and reassembled when moving to different work sites. Types include tower cranes and gantry cranes. Rail-mounted cranes mainly consist of several parts, including a hoisting mechanism, a trolley mechanism, a main trolley mechanism, a power room, and a driver's cab.

[0003] Currently, in the manufacturing process of rail-mounted cranes, whether processing a single part or assembling various parts, the use of flange plates for connection is unavoidable. Due to the nature of their application, flange plates are often quite large, so CNC machining is typically used to process steel plates into the required flange shapes. After CNC machining such as milling, the free edges of the flange plates need to be deburred and chamfered. Currently, chamfering is mainly done by hand polishing with a grinding machine. However, this method cannot control the uniformity of the angle during the chamfering process, and the force of manual polishing is difficult to control, easily leading to stubborn quality defects such as cuts and pits on the free edges. At the same time, the large amount of jet sparks generated during manual grinding poses a significant safety risk, and the large amount of inhalable particles and noise from the grinding fumes can cause harm to the operators. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a CNC steel plate chamfering auxiliary tooling that can effectively control chamfering accuracy and reduce defects.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a telescopic transport beam, the innovation of which lies in: including

[0006] An auxiliary support is provided, which consists of a horizontal support and a diagonal support. The horizontal support is placed on a CNC steel plate. A limit component is also provided between the bottom of the horizontal support and the CNC steel plate. One side of the diagonal support is hinged to the horizontal support, and the other side is connected to the horizontal support through the cooperation of an adjusting component. The diagonal support swings up and down along the hinge point between the diagonal support and the horizontal support.

[0007] An angle grinder is also installed on the inclined support, and the angle grinder swings synchronously with the inclined support. The angle grinder is inverted on the inclined support, and a conical rotary file is installed at the grinding head of the angle grinder.

[0008] Furthermore, the adjusting component includes a pair of parallel adjusting plates, each adjusting plate being an arc-shaped plate. The bottom end of the adjusting plate is fixed to the horizontal support. Adjusting bolts corresponding to the adjusting plates are connected to both sides of the diagonal support. Arc-shaped adjusting holes are provided on the adjusting plates to allow the adjusting bolts to pass through and move. One side of the adjusting bolt is fixed to the diagonal support, and the other side passes through the adjusting hole and is tightened by adjusting nuts.

[0009] Furthermore, the connection between the angle grinder and the inclined support is as follows: a sleeve is also provided on the inclined support, the sleeve has a through hole for the grinding head of the angle grinder to pass through, and after the grinding head of the angle grinder is inserted into the sleeve, the angle grinder is tightened and fixed by the cooperation of a pair of tightening bolts.

[0010] Furthermore, the limiting component includes a limiting tube fixed to the bottom end of the horizontal support. Several limiting balls are also installed on the side of the limiting tube near the CNC steel plate, and the limiting balls are in contact with the side wall of the CNC steel plate.

[0011] Furthermore, a movable ball bearing is installed at the bottom end of the horizontal support.

[0012] The advantages of this utility model are as follows: The auxiliary tooling in this utility model, through the design of an auxiliary support to cooperate with the angle grinder, can effectively fix the angle of the angle grinder during the processing of the free edge of the flange plate after milling, effectively solving the problem that hand-held grinding cannot effectively control the angle and force, thereby reducing the various defects caused by manual grinding.

[0013] The adjustment mechanism is designed with an adjustment plate, adjustment bolts, and adjustment nuts to better adjust the angle of the diagonal brace, thereby adjusting the angle of the angle grinder.

[0014] The design of the limiting component uses a combination of limiting tubes and limiting balls to limit the relative position of the auxiliary support and the CNC steel plate, ensuring that the auxiliary support can move smoothly along the edge of the CNC steel plate to facilitate subsequent processing of the CNC steel plate.

[0015] The moving ball bearings at the bottom of the horizontal support are designed to reduce friction between the horizontal support and the CNC steel plate, thereby reducing surface contact resistance and allowing the horizontal support to move more smoothly on the surface of the CNC steel plate.

[0019] like Figure 1 , Figure 2 The CNC steel plate chamfering auxiliary tooling shown includes:

[0020] An auxiliary support is provided, consisting of a horizontal support 2 and a diagonal support 3. Both the horizontal support 2 and the diagonal support 3 are rectangular frame structures welded together from several horizontal and vertical bars. The horizontal support 2 is placed on the CNC steel plate 1, and a movable ball bearing 21 is installed at the bottom of the horizontal support 2. The movable ball bearing 21 at the bottom of the horizontal support 2 is used to reduce the friction between the horizontal support 2 and the CNC steel plate 1, reduce surface contact resistance, and allow the horizontal support 2 to move more smoothly on the surface of the CNC steel plate 1.

[0021] A limiting component is also provided between the bottom end of the horizontal support 2 and the CNC steel plate. The limiting component includes a limiting tube 4, which is a square tube structure. The limiting tube 4 is fixed to the bottom end of the horizontal support 2. Several limiting balls 5 are also installed on the side of the limiting tube 4 near the CNC steel plate 1, and the limiting balls 5 are in contact with the side wall of the CNC steel plate 1. The design of the limiting component, using the cooperation of the limiting tube 4 and the limiting balls 5, plays a limiting role in the relative position of the auxiliary support and the CNC steel plate 1, ensuring that the auxiliary support can move smoothly along the edge of the CNC steel plate 1, so as to facilitate the subsequent processing of the CNC steel plate 1.

[0022] One side of the diagonal brace 3 is hinged to the horizontal support 2, and the other side of the diagonal brace 3 is connected to the horizontal support 2 through the cooperation of the adjusting part. The diagonal brace 3 can swing up and down along the hinge point between the diagonal brace 3 and the horizontal support 2.

[0023] The adjusting component includes a pair of parallel adjusting plates 6, located on either side of the diagonal brace 3. Each adjusting plate 6 is an arc-shaped plate, with its bottom end welded and fixed to the horizontal support 2. Adjusting bolts 61, corresponding to the adjusting plates 6, are connected to both sides of the diagonal brace 3. Arc-shaped adjusting holes 63 are formed on the adjusting plates 6, allowing the adjusting bolts 61 to pass through and move. The adjusting holes 63 extend along the arc of the adjusting plate 6. One side of the adjusting bolt 61 is fixed to the diagonal brace 3, and the other side passes through the adjusting hole 63 and is tightened by an adjusting nut 62. The design of the adjusting component, using the adjusting plates 6, adjusting bolts 61, and adjusting nuts 62, allows for better adjustment of the angle of the diagonal brace 3, thus enabling adjustment of the angle grinder 7.

[0024] An angle grinder 7 is also installed on the diagonal support bracket 3, and the angle grinder 7 swings synchronously with the diagonal support bracket 3. The angle grinder 7 is inverted on the diagonal support bracket, and a conical rotary file 71 is also installed at the grinding head of the angle grinder 7. The conical rotary file 71 is used to grind the edge of the CNC steel plate 1.

[0025] The connection between the angle grinder 7 and the inclined support bracket 3 is as follows: a sleeve 31 is also provided on the inclined support bracket 3. The sleeve 31 has a through hole for the grinding head of the angle grinder 7 to pass through. After the grinding head of the angle grinder 7 is inserted into the sleeve 31, the angle grinder 7 is tightened and fixed by the cooperation of a pair of tightening bolts 32. Both the inclined support bracket 3 and the sleeve 31 have threaded through holes for the tightening bolts 32 to pass through. The connection between the angle grinder 7 and the inclined support bracket 3 is achieved by the cooperation of the sleeve 31 and the tightening bolts 32, which facilitates the installation of the angle grinder 7 and subsequent disassembly and maintenance.

[0026] Working principle: When grinding the free edge of the CNC steel plate 1, first place the horizontal support 2 on the upper surface of the CNC steel plate 1, and place the moving ball 21 against the CNC steel plate 1. Then, place the limiting ball 5 at the side end of the limiting tube 4 against the side wall of the CNC steel plate 1 to limit the position of the auxiliary support. Then, manually push the auxiliary support along the edge of the CNC steel plate 1 and use the conical rotating file 71 of the angle grinder 7 to grind the CNC steel plate 1. During the movement, ensure that the limiting ball 5 always fits against the side wall of the CNC steel plate 1.
