Description

Technical Field

[0001] The utility model relates to a trolley case production device, in particular to a trolley case body trimming device. Background Art

[0002] Aluminum alloy trolley cases have higher strength and durability than ordinary trolley cases, so they are more popular in the market. The case of an aluminum alloy trolley case is made of aluminum alloy, and its production process is to form the aluminum sheet through a stamping one-piece forming process, which has high production efficiency. The case after stamping is a semi-finished product, and it needs to go through subsequent processing steps such as punching and polishing. Among them, the polishing process of the case is currently mostly done manually, which not only increases labor costs and limits production efficiency, but also causes uneven polishing quality. Summary of the invention

[0003] The utility model provides a trolley case body trimming device, which solves the problem in the prior art that the aluminum alloy trolley case body grinding is not automated, resulting in low production efficiency and uneven grinding quality.

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions: a trolley case trimming device, characterized in that it comprises: a support platform, which is horizontally fixed and has a plurality of adsorption holes on its upper surface, and the adsorption holes are all connected to a negative pressure device;

[0005] Four sets of side wall clamping mechanisms, including a clamping action module and a clamping plate rotatably connected thereto, wherein the clamping plate can abut against the side wall of the suitcase body under the drive of the clamping action module;

[0006] The servo grinding mechanism includes a three-axis servo mechanism, a translation seat, a servo motor fixed on the translation seat, a rotating seat transmission-connected to the servo motor, a grinding motor and a grinding head arranged on the rotating seat, wherein the rotating axis of the rotating seat is vertically arranged, and the rotating axis of the grinding motor is horizontally arranged.

[0007] The use of the utility model is as follows: the box can be loaded and unloaded by manual or automated equipment, the box to be polished is placed in the middle of the support table, the adsorption hole generates negative pressure, which can produce an adsorption effect on the box, the edge of the box is the area to be polished, and the four sets of side wall clamping mechanisms clamp the four side walls of the box. Because the boxes of different products have different draft angles, the clamping plate of the utility model is horizontally driven and connected to the clamping action module, so that it can adaptively fit and abut against the side wall of the box, and rubber strips can be provided on the clamping surface of the clamping plate to increase The friction coefficient can enhance the fixing effect. After the box is completely fixed, the servo grinding mechanism can start to operate. The three-axis servo mechanism drives the translation seat to descend to the grinding height. The servo motor adjusts the direction of the rotating seat so that the axis of the grinding head is perpendicular to the grinding part. Then the three-axis servo mechanism drives the translation seat to translate along the preset path. At the same time, the servo motor adjusts the rotating seat so that the axis of the grinding head maintains a real-time vertical state with the grinding part on the box. After grinding is completed, the servo grinding mechanism resets, the four sets of side wall clamping mechanisms release the box, the adsorption holes close the negative pressure state, and the box is unloaded.

[0008] Furthermore, a dust hood is fixed on the rotating seat, and the dust hood is wrapped around the outside of the grinding head, with only the bottom of the grinding head exposed. The dust hood is provided with an air intake port, and the air intake port can be connected to the exhaust device through a hose. When the grinding head is in the grinding state, a large amount of cutting debris will be generated. If these cutting debris are not collected, the cutting debris will easily accumulate on the support table and the clamping plate, which will affect the positioning accuracy of the support table and the clamping plate over time, and further affect the grinding quality. To this end, the utility model prevents the cutting debris from splashing by setting a dust hood, and the negative pressure effect generated by the air intake port will suck away the cutting debris in the dust hood.

[0009] Furthermore, a counterweight is provided at the bottom of the clamping plate, and under the action of the counterweight, the clamping surface of the clamping plate can rotate autonomously to a state tending to be vertical. Because the draft angle of the side wall of the box is generally small, the side wall generally tends to be vertical, so when the clamping plate abuts against the side wall of the box, the angle between the two is small, so the clamping plate can easily fit with the side wall of the box by flipping itself. If the clamping plate is not counterweighted, the clamping surface of the clamping plate may flip to a larger tilted state, which may cause the clamping plate to be unable to rotate smoothly when it abuts against the side wall of the box, thereby causing damage to the box.

[0010] Furthermore, a colloid washer protruding upward is provided on the upper surface of the support platform and at the periphery of the adsorption hole. The colloid washer has better fit when in contact with the box body, and the adsorption effect of the adsorption hole is better.

[0011] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The box body can be fixed under the action of four sets of side wall clamping mechanisms and the support platform, and the servo grinding mechanism can autonomously grind the edge of the box body along a preset path, and under the adjustment of the servo motor, the axial direction of the grinding head is always perpendicular to the grinding part, so that burrs are not easy to be generated after grinding, and the grinding effect is better; 2. A dust hood is set to prevent cutting chips from splashing, and the negative pressure effect generated by the air intake port will suck away the cutting chips in the dust hood, so that the working area can be kept clean.

[0017] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0019] Example 1: See Figure 1 and Figure 5 A trolley case trimming device comprises: a support platform 100, which is horizontally fixed and has a plurality of adsorption holes 110 on its upper surface, each of which is connected to a negative pressure device, and an upwardly protruding rubber gasket 120 is provided on the upper surface of the support platform and located at the periphery of the adsorption holes;

[0020] See Figure 3, four sets of side wall clamping mechanisms 200, including a clamping action module and a clamping plate 210 rotatably connected thereto, the clamping plate can abut against the side wall of the suitcase body under the drive of the clamping action module;

[0021] See Figure 1 and Figure 2 The servo grinding mechanism 300 includes a three-axis servo mechanism 310, a translation seat 320, a servo motor 330 fixed on the translation seat, a rotating seat 340 transmission-connected to the servo motor, a grinding motor 350 and a grinding head 360 arranged on the rotating seat, the rotating axis of the rotating seat is vertically arranged, and the rotating axis of the grinding motor is horizontally arranged.

[0022] See Figure 2 A dust hood 370 is also fixed on the rotating seat. The dust hood is wrapped around the outside of the grinding head, leaving only the bottom of the grinding head exposed. An air intake port 380 is provided on the dust hood, which can be connected to the exhaust device through a hose. When the grinding head is in the grinding state, a large amount of cutting debris will be generated. If these cutting debris are not collected, the cutting debris will easily accumulate on the support table and the clamping plate, which will affect the positioning accuracy of the support table and the clamping plate over time, and further affect the grinding quality. To this end, this embodiment prevents the cutting debris from splashing by setting a dust hood, and at the same time, the negative pressure effect generated by the air intake port will suck away the cutting debris in the dust hood.

[0023] A counterweight is provided at the bottom of the clamping plate, and under the action of the counterweight, the clamping surface of the clamping plate can rotate autonomously to a vertical state. Because the draft angle of the side wall of the box is generally small, the side wall is generally vertical, so when the clamping plate abuts against the side wall of the box, the angle between the two is small, so the clamping plate can easily fit with the side wall of the box by flipping itself. If the clamping plate is not counterweighted, the clamping surface of the clamping plate may flip to a larger tilted state, which may cause the clamping plate to not rotate smoothly when it abuts against the side wall of the box, thereby causing damage to the box.

[0024] See Figure 3 The clamping action module is a horizontally arranged first cylinder 220, and the clamping plate is rotatably connected to the cylinder rod of the first cylinder.

[0025] The use of this embodiment is as follows: the box can be loaded and unloaded manually or by automated equipment. The box to be polished is placed in the middle of the support table. The adsorption holes generate negative pressure, which can produce an adsorption effect on the box. The edge of the box is the area to be polished. Four sets of side wall clamping mechanisms clamp the four side walls of the box. Because the boxes of different products have different draft angles, the clamping plate of this embodiment is horizontally connected to the clamping action module so that it can adaptively fit and abut against the side wall of the box. Rubber strips can also be set on the clamping surface of the clamping plate to increase friction. The friction coefficient is increased to enhance the fixing effect. After the box is completely fixed, the servo grinding mechanism can start to operate. The three-axis servo mechanism drives the translation seat to descend to the grinding height. The servo motor adjusts the direction of the rotating seat so that the axial direction of the grinding head is perpendicular to the grinding part. Then the three-axis servo mechanism drives the translation seat to translate according to the preset path. At the same time, the servo motor adjusts the rotating seat so that the axial direction of the grinding head and the grinding part on the box are kept vertical in real time. After the grinding is completed, the servo grinding mechanism is reset, the four sets of side wall clamping mechanisms release the box, the adsorption holes are closed to the negative pressure state, and the box is unloaded. The rotation direction of the bottom of the grinding head is consistent with the movement direction of the translation seat, which is conducive to reducing the burrs caused by grinding.

[0026] Example 2: See Figure 4 , which is different from Example 1 in that the clamping action module includes an L-shaped arm 230 and a second cylinder 240 rotatably connected to the support platform, the cylinder body of the second cylinder is hinged to the bottom of the support platform, the cylinder rod of the second cylinder is hinged to the bottom end of the L-shaped arm, and the clamping plate is rotatably connected to the upper end of the L-shaped arm. Compared with Example 1, the clamping action module of this embodiment occupies less space in the horizontal width direction, which is conducive to reducing the horizontal width of the equipment.

[0027] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
