[0002] With the rapid development of new energy vehicles, the blade battery used in these vehicles has also seen significant growth. The blade battery housing is made of a square tube and end caps. The tube processing includes polishing both ends.

[0003] The existing grinding methods all use a clamp to fix the square tube first, and then grind one end of it with a grinder. After one end is polished, the square tube is removed from the clamp, turned around, and re-clamped and fixed, and the other end is polished with a grinder.

[0004] The problems with the above grinding method are: 1. Only one end can be ground at a time, resulting in low grinding efficiency; 2. Since the square tube needs to be removed and re-clamped after one end is ground, there are assembly errors, and the length accuracy of the processed square tube is poor. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide an automatic square tube end face grinding mechanism that clamps the two ends of the required square tube through a clamp assembly, and then grinds the two ends of the square tube respectively through a grinding assembly to improve the grinding efficiency while ensuring the grinding accuracy.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An automatic grinding mechanism for the end face of a square tube is characterized in that it comprises: a frame; a clamp assembly, which is arranged on the frame and is used to clamp the square tube to be ground; a grinding assembly, wherein the number of the grinding assemblies is two and they are respectively arranged at both ends of the clamp assembly; each of the grinding assemblies comprises: a horizontal sliding seat, which is slidably arranged along a first direction relative to the frame to slide closer to or away from the clamp assembly; a horizontal driving device, which is used to drive the horizontal sliding seat to slide; a lifting sliding seat, which is slidably arranged along a vertical direction relative to the horizontal sliding seat to enable the lifting sliding seat to move up and down; a lifting driving device, which is used to drive the lifting sliding seat to slide; and a grinder, which is arranged on the lifting sliding seat.

[0009] The present invention is further configured such that: the rotation axis of the grinding wheel is perpendicular to the first direction, and the angle between the rotation axis of the grinding wheel and the vertical direction is α, wherein 0°<α<90°.

[0010] The utility model is further set as follows: 10°<α<20°.

[0011] The utility model is further configured such that: the horizontal drive device and the lifting drive device both adopt electric cylinders.

[0012] The present invention is further configured as follows: the number of the clamp assemblies is two groups, and the two groups of clamp assemblies are arranged at intervals along a first direction; each of the clamp assemblies includes: a clamping sliding seat, the clamping sliding seat is arranged to slide along the first direction relative to the frame to slide and adjust the spacing between the two groups of clamping assemblies; a support platform, the support platform is arranged on the top of the clamping sliding seat to support the square pipe to be polished upward; and a pneumatic chuck, the pneumatic chuck is arranged on the clamping sliding seat to clamp and fix the square pipe to be polished.

[0013] The utility model is further configured as follows: it also includes an adjustment drive device; the adjustment drive device includes a drive motor, an adjustment screw, a first adjustment nut and a second adjustment nut, the adjustment screw is rotatably set on the frame, the adjustment screw includes a first section and a second section with opposite thread directions, the first adjustment nut is threadedly engaged with the first section, and the second adjustment nut is threadedly engaged with the second section, the first adjustment nut and the second adjustment nut are respectively fixedly arranged on different clamping sliding seats, and the drive motor is used to drive the adjustment screw to rotate.

[0014] The present invention is further configured as follows: at least one set of clamp components further comprises a through-beam sensor, and the through-beam sensor is used to detect whether there is a square tube on the clamp component.

[0015] The utility model is further configured as follows: the frame includes a slide rail, the track direction of the slide rail is arranged along a first direction, and each of the horizontal sliding seat and the clamping sliding seat is slidably arranged on the slide rail.

[0017] By adopting the above technical solution, the square tube to be clamped is clamped and fixed by the clamp assembly. After the fixation is completed, the grinding assemblies at both ends work separately to grind the excess at both ends of the square tube. Since the grinding assemblies at both ends do not interfere with each other, they can work simultaneously to grind both ends of the square tube, which makes the grinding efficiency higher. Moreover, the square tube is fixed after being clamped by the clamp assembly, and the length accuracy of the square tube after processing is determined by the movement of the two groups of grinding assemblies to the minimum spacing. When the control program remains unchanged, it is only necessary to ensure that the grinding assemblies at both ends can grind to the square tube, and ensure that the lengths of the processed square tubes are the same to ensure the processing accuracy.

[0027] In order to enable those skilled in the art to better understand the present invention and thus more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention. The specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of implementation of the present invention. The conventional selections and replacements made by those skilled in the art under the guidance of the present invention should be deemed to be within the scope of protection claimed by the present invention.

[0028] like Figures 1-6 As shown, the utility model discloses an automatic grinding mechanism for the end face of a square tube, comprising:

[0029] Rack 1;

[0030] A clamp assembly 2, which is disposed on the frame 1 and is used to clamp the square tube 5 to be polished;

[0031] The polishing components 3 are provided in two groups and are respectively arranged at the left and right ends of the clamp component 2 .

[0032] Therefore, the square tube 5 to be clamped is clamped and fixed by the clamp assembly 2. After the fixation is completed, the grinding assemblies 3 at both ends work separately to grind the excess at both ends of the square tube 5. Since the grinding assemblies 3 at both ends do not interfere with each other, they can work simultaneously to grind both ends of the square tube 5, making the grinding efficiency higher. Moreover, the square tube 5 is fixed after being clamped by the clamp assembly 2, and the length accuracy of the square tube 5 after processing is determined by the movement of the two groups of grinding assemblies 3 to the minimum spacing. Under the condition that the control program remains unchanged, it is only necessary to ensure that the grinding assemblies 3 at both ends can grind to the square tube 5, and ensure that the lengths of the processed square tubes 5 are the same to ensure the processing accuracy. Specifically, each grinding assembly 3 includes:

[0033] A horizontal sliding seat 31 is provided to slide along the left and right directions relative to the frame 1 to slide closer to or away from the clamp assembly 2;

[0034] A horizontal driving device 32 is used to drive the horizontal sliding seat 31 to slide;

[0035] The lifting sliding seat 33 is arranged to slide vertically relative to the horizontal sliding seat 31 so that the lifting sliding seat 33 moves up and down;

[0036] A lifting drive device 34 is used to drive the lifting sliding seat 33 to slide;

[0037] The grinder 35 is disposed on the lifting and sliding seat 33 .

[0038] Therefore, after the square tube 5 is clamped, the grinder 35 is started, and the grinder 35 grinds the excess of the square tube 5 under the horizontal driving device 32 driving the horizontal sliding seat 31 to slide and the lifting driving device 34 driving the lifting sliding seat 33 to slide.

[0039] Specifically, the grinder 35 includes a mounting base 351, a grinding wheel 352, and an output motor 353. The mounting base 351 is arranged on the lifting and sliding base 33, and the grinding wheel 352 is rotatably arranged on the mounting base 351. The output motor 353 is fixed to the mounting base 351 and is linked to the grinding wheel 352 through a linkage structure such as a gear box, so that the output motor 353 works and drives the grinding wheel 352 to rotate at high speed. The outer periphery of the grinding wheel 352 is provided with a columnar grinding surface 3521, so that the grinding surface 3521 acts on the end of the square tube to perform grinding.

[0040] Preferably, the mounting seat 351 in this embodiment adopts the combination of a linear rail and a slider to achieve sliding movement along the left and right directions on the lifting sliding seat 33. In addition, an abutment seat 37 is fixed on the lifting slide seat by bolts, and a guide screw 36 is provided on the mounting seat 351, which passes through the abutment seat 37 and is fixedly connected to the mounting seat with threads, and the length direction of the guide screw 36 is along the left and right directions. In addition, a reset spring 38 is provided on the outer periphery of the guide screw 36, one end of which is abutted against the abutment seat 37 and the other end of which is abutted against the mounting seat 351, so that the reset spring 38 generates a reset force to push the mounting seat 351 toward the clamp assembly 2.

[0041] Therefore, when the grinding wheel 352 moves toward the square tube 5, the return spring 38 ensures that the grinding wheel 352 elastically presses against the square tube 5. When the feeding amount of the grinding wheel 352 toward the square tube 5 is too large, the sliding amount of the mounting base 351 relative to the lifting sliding base 33 is larger, and the elastic potential energy generated by the spring compression is larger, so that the force exerted by the grinding wheel 352 on the square tube 5 is greater and the grinding is performed faster, making the grinding more reliable.

[0042] In this embodiment, the rotation axis of the grinding wheel 352 is perpendicular to the first direction, and the angle between the rotation axis of the grinding wheel 352 and the vertical direction is α, wherein 0°<α<90°, preferably, 10°<α<20°, and this embodiment specifically adopts 15°.

[0043] Therefore, by tilting the grinding wheel 352, the square tube 5 is clamped as shown in the figure, and the grinding surface 3521 actually used for grinding the vertical edge of the square tube 5 is larger, thereby preventing the grinding wheel 352 from being excessively worn due to grinding at a concentrated position and becoming unusable, thereby increasing the service life of the grinding wheel 352.

[0044] In this embodiment, the horizontal drive device 32 and the lifting drive device 34 both use electric cylinders.

[0045] The two horizontal drive devices 32 in this embodiment are arranged in a front-to-back direction.

[0046] The lifting drive device 34 is disposed at the bottom of the horizontal sliding seat 31 .

[0047] Preferably, there are two groups of clamp assemblies 2, and the two groups of clamp assemblies 2 are arranged at intervals in the left-right direction, so that the square tube 5 is clamped by the two groups of clamp assemblies 2 to improve the clamping stability.

[0048] Specifically, each clamp assembly 2 includes:

[0049] The clamping sliding seat 21 is slidably arranged in the left and right directions relative to the frame 1 to slide and adjust the distance between the two sets of clamping components;

[0050] The support platform 22 is provided on the top of the clamping sliding seat 21 to support the square tube 5 to be polished upward;

[0051] The pneumatic chuck 23 is disposed on the clamping sliding seat 21 to clamp and fix the square tube 5 to be polished.

[0052] Therefore, the processing of square tubes 5 of different sizes is adapted by adjusting the spacing between the clamp assemblies 2 by sliding the clamping sliding seat 21. After the adjustment is completed, the square tube 5 is placed on the support platform 22. The square tube 5 is ensured to be placed horizontally under the action of the support platforms 22 on the left and right sides. Then, the square tube 5 is clamped by the pneumatic chucks 23 on the left and right sides to ensure the stability of the clamping.

[0053] In addition, it also includes an adjustment drive device 4; the adjustment drive device 4 includes a drive motor 41, an adjustment screw 42, a first adjustment nut 43 and a second adjustment nut 44, the adjustment screw 42 is rotatably set on the frame 1 through a bearing seat, the adjustment screw 42 includes a first section 421 and a second section 422 with opposite thread directions, the first adjustment nut 43 is threadedly fitted with the first section 421, and the second adjustment nut 44 is threadedly fitted with the second section 422, the first adjustment nut 43 and the second adjustment nut 44 are respectively fixedly set on different clamping sliding seats 21, and the drive motor 41 is used to drive the adjustment screw 42 to rotate.

[0054] Therefore, the adjustment screw 42 is driven to rotate by the operation of the driving motor 41, so that under the cooperation of the first adjustment nut 43 and the first section 421, and the cooperation of the second adjustment nut 44 and the second section 422, the two clamping sliding seats 21 can be synchronously and reversely approached or moved away, and the adjustment is faster.

[0055] Among them, at least one group of clamp components 2 also includes a radiation sensor 24, which is arranged on the support platform 22, and the infrared ray 241 emitted by the radiation sensor 24 is located directly above the support platform 22, so as to determine whether subsequent processing actions can be performed by detecting whether a square tube 5 is placed above the support platform 22.

[0056] The rack 1 in this embodiment includes two slide rails 11, the track direction of the slide rails 11 extends in the left-right direction and is arranged along the front-back spacing. Each horizontal sliding seat 31 and the clamping sliding seat 21 are slidably set on the slide rails 11 by means of sliders.

[0057] Preferably, each grinding assembly 3 includes multiple grinders 35, specifically four in this embodiment, and the multiple grinders 35 in each grinding assembly 3 are arranged in the front-to-back direction. Correspondingly, each clamp assembly 2 includes multiple pneumatic chucks 23, specifically four in this embodiment, and the multiple pneumatic chucks 23 in each clamp assembly 2 are arranged in the front-to-back direction. This allows for simultaneous grinding of a greater number of square tubes 5, further improving production efficiency.

[0058] In this embodiment, the left-right direction is defined as the first direction, and the front-back direction is defined as the second direction.

[0059] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
