Description

Technical Field

[0001] This utility model relates to the field of chamfering equipment, specifically a chamfering device. Background Technology

[0002] Grinding equipment is used to grind sheet metal parts to achieve functions such as chamfering and deburring. The grinding device drives the grinding head or grinding wheel through a motor belt assembly. The traditional tensioning mechanism tensions the transmission belt by using a tensioning pulley. This method requires a tensioning pulley and a sheet metal part to install it, which is not only difficult to install, but also prone to loosening during use.

[0003] For example, Chinese patent CN208409433U discloses a deburring and chamfering grinding device for U-shaped buckles, including a drive mechanism, a forward grinding mechanism, a reverse grinding mechanism, and a tension adjustment mechanism. The forward and reverse grinding mechanisms are symmetrically and staggeredly mounted on an upper support platform. The forward grinding mechanism is driven by the drive mechanism, and the forward grinding mechanism drives the reverse grinding mechanism through gear meshing. The two grinding mechanisms rotate in opposite directions, which can symmetrically grind the edge corners of the U-shaped buckle, ensuring that the two bottom feet of the U-shaped buckle are ground into uniform arc corners. The aforementioned patent uses a tension adjustment mechanism to contact the outside of the transmission belt. The tension adjustment mechanism includes a screw, nut, fixing frame, and tension wheel. The tension wheel contacts and presses the transmission belt. The tension adjustment mechanism has a complex structure, and the tension wheel is prone to loosening during operation, making adjustment inconvenient.

[0004] Therefore, it is necessary to provide a chamfering device. Utility Model Content

[0005] The chamfering device provided by this utility model effectively solves the problem that the chamfering device is not convenient for adjusting the belt drive component.

[0006] The technical solution adopted in this utility model is: The chamfering device includes a machine base, a platform on the machine base, and two grinding mechanisms symmetrically arranged on the machine base along the platform. Each grinding mechanism includes a first base on the machine base, a first slide table slidably arranged on the base in the X direction, a first drive assembly on the base for driving the first slide table, a grinding head, a transmission sleeve, a motor, a clamping box for mounting the transmission sleeve on the first slide table, a mounting bracket for mounting the motor, a belt drive assembly connecting one end of the transmission sleeve to the motor shaft, a spring clip for fixing the grinding head at the other end of the transmission sleeve, and a support and adjustment assembly on the outer wall of the clamping box. The mounting bracket includes a first frame on the first slide table, a pin, and a second frame rotatably connected to the upper end of the first frame via the pin for mounting the motor. The second frame has a notch on the side away from the first frame that connects to the support and adjustment assembly.

The No. 3 screw can extend into the notch, and the two nuts abut against the upper and lower end faces of the No. 2 frame respectively.

[0008] Furthermore, the transmission sleeve includes a sleeve fixed by the clamping shaft box, several ball bearings whose outer ring abuts against the inner wall of the sleeve, end caps disposed at both ends of the sleeve, and a transmission shaft that passes through the end caps and is connected to the inner ring of the ball bearings.

[0009] Furthermore, the belt drive assembly includes a driven pulley coaxially fixed at one end of the drive shaft, a driving pulley coaxially fixed on the motor shaft, and a drive belt that is connected to the driving pulley and the driven pulley.

[0010] Furthermore, the loading platform includes a base plate mounted on the machine platform, a loading platform slidably mounted on the base plate along the Y-axis, and a hydraulic cylinder fixedly mounted on the base plate for driving the loading platform to slide along the Y-axis.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the chamfering device provided in the embodiments of this application includes a machine base 1, a platform 2 disposed on the machine base 1, and two grinding mechanisms 3 symmetrically disposed on the machine base 1 along the platform 2. Each grinding mechanism 3 includes a first base 301 disposed on the machine base 1, a first slide 302 slidably disposed on the base in the X direction, a first drive assembly 303 disposed on the base for driving the first slide 302 to slide, a grinding head 304, a transmission sleeve 305, a motor 306, a shaft clamping box 307 disposed on the first slide 302 for mounting the transmission sleeve 305, and a mounting box for mounting the motor 306. The frame 308 includes a seat 308, a belt drive assembly 309 connecting one end of the transmission sleeve 305 to the shaft of the motor 306, a spring clip 310 for fixing the grinding head 304 at the other end of the transmission sleeve 305, and a support adjustment assembly 311 on the outer wall of the clamping shaft box 307. The seat 308 includes a first frame 801 set on the first slide 302, a pin 802, and a second frame 803 rotatably connected to the upper end of the first frame 801 via the pin 802 for mounting the motor 306. The second frame 803 has a notch 800 on the side away from the first frame 801 that connects to the support adjustment assembly 311.

[0021] During actual product polishing, the product is fixed on the platform 2 using a dedicated fixture. The motor 306 drives the belt drive assembly 309, which in turn rotates the transmission sleeve 305. This causes the transmission sleeve 305 to rotate the spring clip 310 and the grinding head 304. The first drive assembly 303 then drives the first slide 302 towards the end of the product, bringing the grinding head 304 into contact with the product end for polishing. When it is necessary to adjust the height of the motor 306 to adjust the tension of the belt drive assembly 309, the support adjustment assembly 311 is released, and the second frame 803 is rotated to change the height of the motor 306. This corresponds to adjusting the support height of the support adjustment assembly 311 on the second frame 803. Then, the support adjustment assembly 311 is re-fixed to the notch 800.

[0022] In the above design, the height of the motor 306 can be easily adjusted by the cooperation of the support adjustment component 311 and the second frame 803, thereby enabling rapid adjustment of the tension of the belt drive component 309.

[0023] Specifically: such as Figure 2 As shown, the support adjustment assembly 311 includes a fixed base 111 fixedly mounted on the clamping shaft box 307 and provided with two holes for the No. 3 shaft 112, a No. 3 shaft 112 whose two ends are respectively rotatably connected to the two holes for the No. 3 shaft 112, a No. 3 screw 113 fixedly mounted on the No. 3 shaft 112 and located between the two holes for the No. 3 shaft 112, and two nuts 114 threadedly connected to the No. 3 screw 113. The No. 3 screw 113 can extend into the notch 800, and the two nuts 114 abut against the upper end face and the lower end face of the No. 2 frame 803, respectively.

[0024] In actual use, when the support adjustment assembly 311 fixes the second frame 803, the third screw 113 extends into the notch 800, and the two nuts 114 abut against the upper and lower end faces of the second frame 803, respectively. When adjustment of the second frame 803 is required, first loosen the two nuts 114 to allow the second frame 803 to rotate. After the second frame 803 rotates to the predetermined position, tighten the two nuts 114 again.

[0025] In the above design, the structural design and specific implementation of the support adjustment component 311 can effectively fix and loosen the second frame 803, making it easy to quickly adjust the second frame 803 and quickly fix it after adjustment.

[0026] Specifically: such as Figure 1 , Figure 2 and Figure 4As shown, the transmission sleeve 305 includes a sleeve 51 fixed by the clamping shaft box 307, a plurality of ball bearings 52 whose outer ring abuts against the inner wall of the sleeve 51, end caps 53 disposed at both ends of the sleeve 51, and a transmission shaft 54 ​​whose two ends pass through the end caps 53 and are connected to the inner ring of the ball bearings 52. The spring clip 310 is connected to the transmission shaft 54.

[0027] In actual operation, the motor 306 drives the belt drive assembly 309 to rotate the drive shaft 54, which in turn drives the spring clip 310 and the grinding head 304 to rotate synchronously. The ball bearing 52 can reduce the friction during the rotation of the drive shaft 54.

[0028] In the above design, the structural design and specific implementation of the transmission sleeve 305 can effectively realize the rotation of the transmission shaft 54.

[0029] Specifically: such as Figure 1 and Figure 2 As shown, the belt drive assembly 309 includes a driven pulley 92 coaxially fixed at one end of the drive shaft 54, a driving pulley 91 coaxially fixed on the rotating shaft of the motor 306, and a drive belt 93 that is drively connected to the driving pulley 91 and the driven pulley 92.

[0030] In actual use, the motor 306 drives the drive pulley 91 to rotate, which in turn drives the driven pulley 92 to rotate with the help of the transmission belt 93.

[0031] In the above design, the structural design and specific implementation of the belt drive assembly 309 can effectively achieve transmission.

[0032] Specifically: such as Figure 1 As shown, the placement platform 2 includes a base plate 201 mounted on the machine base 1, a feeding platform 202 slidably mounted on the base plate 201 along the Y-axis direction, and an oil cylinder 203 fixedly mounted on the base plate 201 for driving the feeding platform 202 to slide along the Y-axis direction.

[0033] In actual use, after the fixture carrying the product is fixed to the feeding table 202 by bolts, the hydraulic cylinder 203 drives the feeding table 202 to move to the processing position. After the product has been polished, the hydraulic cylinder 203 drives the retaining table to move out of the processing position.

[0034] In the above design, the structural design and specific implementation of the platform 2 can effectively move the product to the processing position.

[0035] Specifically: such as Figure 2 and Figure 3As shown, the first frame 801 includes a first plate 8011 fixedly mounted on the first slide table 302 and a first cylinder 8012 mounted on the first plate 8011 along the X direction. The second frame 803 includes a second plate 8031 ​​and a second cylinder 8032 mounted on the second plate 8031 ​​along the X direction. The pin 802 is rotatably connected to the first cylinder 8012 and the second cylinder 8032. The notch 800 is provided on the second plate 8031.

[0036] When it is necessary to rotate the No. 2 frame 803, rotating the No. 2 plate 8031 ​​will drive the No. 2 cylinder 8032 to rotate synchronously. During the rotation process, the No. 2 cylinder 8032 rotates around the pin shaft 802.

[0037] In the above design, the structural design and specific implementation of frame 801 and frame 803 can effectively achieve the rotatable connection with pin 802.

[0038] Specifically: the first plate 8011 is welded to the first cylinder 8012, and the second plate 8031 ​​is welded to the second cylinder 8032.

[0039] In the above design, the welding connection method can ensure a stable connection between plate 8011 and cylinder 8012, and between plate 8031 ​​and cylinder 8032, without the need for additional fasteners.

[0040] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
