Description

Technical Field

[0001] This application relates to hardware workpiece processing equipment, specifically a workpiece surface treatment equipment, especially for polishing, sanding, deburring and other treatments on the surface of hardware workpieces. Background Technology

[0002] In the processing of metal parts, surface treatments such as sanding, polishing, and deburring are key processes to ensure the quality of the inner and outer surfaces of the workpieces. Existing equipment typically mounts the surface treatment wheel on top of the frame and is directly driven by a motor on the side of the wheel. This layout causes the rotating parts to be concentrated at a high position on the frame, resulting in a high center of gravity for the equipment. During operation, the rotation of the motor and the surface treatment wheel causes significant vibration, which not only generates considerable noise and interferes with the operating environment, but also easily leads to uneven surface treatment and reduced precision of the workpieces, thus affecting the quality of the finished product. Therefore, it is essential to develop a workpiece surface treatment equipment with a lower center of gravity and less vibration to improve equipment stability and workpiece processing quality. Summary of the Invention

[0003] The purpose of this application is to overcome the shortcomings of existing workpiece surface treatment equipment with a high center of gravity, and to provide a workpiece surface treatment equipment that lowers the center of gravity of the frame by separating the surface treatment wheel and the motor.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] A workpiece surface treatment device includes a frame and at least one grinding device disposed on the frame. The frame includes a base and a support frame disposed on the upper side of the base. The support frame includes a first side plate and a second side plate disposed at a predetermined angle on the upper side of the base, and a support plate connected between the first side plate and the second side plate. The grinding device includes a motor disposed on the base and a transmission shaft assembly disposed on the support plate. The motor is coupled to the transmission shaft assembly via a belt drive mechanism. The transmission shaft assembly is loaded with a surface treatment wheel.

[0006] Compared with the prior art, the workpiece surface treatment equipment of this application sets the motor in the base and sets the transmission shaft assembly and surface treatment wheel on the support frame, so that the motor and surface treatment wheel form a staggered layout, thereby lowering the center of gravity of the whole machine and reducing the vibration generated by the motor and surface treatment wheel during operation. At the same time, the triangular support structure formed by the first side plate, the second side plate and the support plate enhances the rigidity and stability of the frame, thereby effectively improving the quality of workpiece surface treatment and reducing noise during operation.

[0007] Furthermore, the bottom of the support plate is provided with at least one reinforcing plate that connects the first side plate and the second side plate, thereby enhancing the rigidity of the support frame.

[0008] Furthermore, the frame also includes a cover connected to the ends of the first side plate and the second side plate. The cover covers the support plate, and the cover can prevent dust from entering, improve the life of each transmission component, and reduce the number of maintenance times.

[0009] Furthermore, the belt drive mechanism includes a belt, and the first side plate and / or the second side plate are provided with tension pulleys that abut against the outside of the belt. The tension pulleys can adjust the tension of the belt to prevent the belt from slipping.

[0010] Furthermore, the grinding device is configured in two parts, which are installed on opposite sides of the frame. The support plate has a hole in the middle for the belt to pass through. The two grinding devices are arranged opposite each other to balance the center of gravity of the whole machine.

[0011] Furthermore, the frame is equipped with a coating mechanism for each surface treatment wheel. The coating mechanism is equipped with a material storage module and a drive module that drives the material storage module to move relative to the surface treatment wheel. The material storage module is constructed with a material storage tank for storing consumables. The material storage tank is open on the side near the surface treatment wheel. The material storage tank is equipped with a clamping component for fixing consumables. The coating mechanism can increase the functionality of the workpiece surface treatment equipment.

[0012] Furthermore, the clamping assembly includes a clamping cylinder disposed outside the material storage tank, the output end of the clamping cylinder extending into the material storage tank, and is equipped with a clamping member for pressing or releasing consumables.

[0013] Furthermore, the drive shaft assembly extends out of the frame, the surface treatment wheel is mounted on the portion of the drive shaft assembly that extends out of the frame, and the assembly also includes a shield that at least partially surrounds the surface treatment wheel, the shield being provided to prevent dust from splashing.

[0014] Furthermore, the shield is equipped with a dust suction port, which can be connected to an external dust collection device to prevent dust from polluting the environment.

[0015] Furthermore, the side of the shield has a clearance portion that connects to its interior, allowing the workpiece to enter from the side to achieve the treatment of the inner surface of the workpiece.

[0016] Furthermore, it also includes a workpiece fixing device disposed on the outside of the frame for each grinding device. The workpiece fixing device includes a loading mechanism for fixing the workpiece and driving the workpiece to rotate, and a workpiece feeding mechanism for driving the loading mechanism to feed. The loading mechanism is equipped with a mounting base, a workpiece rotating module disposed on the mounting base, and a constant pressure cylinder whose output end is connected to the mounting base. The output end of the constant pressure cylinder can be floated and adjusted to keep the pressure between the workpiece loaded on the workpiece rotating module and the surface treatment wheel constant. The above-mentioned configuration dynamically compensates for the error caused by the wear of the surface treatment wheel, ensures constant grinding pressure, avoids over-grinding or under-grinding, and guarantees the processing quality of the workpiece.

[0017] Another aspect of this application provides a workpiece surface treatment apparatus, including a frame and at least one grinding device. The frame includes a base and a support frame disposed on the upper side of the base. The grinding device includes a motor disposed at the bottom of the base and a transmission shaft assembly disposed on the support frame and located obliquely above the motor. The motor is coupled to the transmission shaft assembly via a belt drive mechanism. The transmission shaft assembly is equipped with a surface treatment wheel. This type of workpiece surface treatment apparatus sets the surface treatment wheel and the motor separately in height, thereby lowering the center of gravity of the entire machine, improving the stability of the equipment and the quality of workpiece surface treatment, and reducing noise during operation.

[0026] The specific embodiments of this application are described below with reference to the accompanying drawings.

[0027] See Figure 1 This embodiment provides a workpiece surface treatment device, which can be used to perform treatments such as polishing, sanding, and deburring on the surface of workpieces. The device as a whole includes a frame 1, a grinding device 2, and a workpiece fixing device 5.

[0028] See Figure 1 , Figure 2 , Figure 4 and Figure 5 In one embodiment, the grinding device 2 includes a motor 21 disposed at the bottom of the frame 1 and a drive shaft assembly 22 located diagonally above the motor 21. The motor 21 is coupled to the drive shaft assembly 22 via a belt drive mechanism 3. The drive shaft assembly 22 is equipped with a surface treatment wheel 23. In this embodiment, the workpiece surface treatment equipment sets the surface treatment wheel 23 and the motor 21 at different heights, thereby lowering the center of gravity of the entire machine, improving the stability of the equipment and the quality of workpiece surface treatment, and reducing noise during operation.

[0029] See Figure 1 , Figure 2 , Figure 4 and Figure 5 In another embodiment, the frame 1 includes a base 11 and a support frame 12 disposed on the upper side of the base 11. The support frame 12 includes a first side plate 121 and a second side plate 122 disposed at a preset angle on the upper side of the base 11, and a support plate 123 connected between the first side plate 121 and the second side plate 122. The grinding device 2 includes a motor 21 disposed on the base 11 and a transmission shaft assembly 22 disposed on the support plate 123. The motor 21 is coupled to the transmission shaft assembly 22 through a belt transmission mechanism 3. The transmission shaft assembly 22 is loaded with a surface treatment wheel 23. The motor 21 can drive the surface treatment wheel 23 to rotate through the transmission shaft assembly 22.

[0030] In this embodiment, the workpiece surface treatment equipment houses the motor 21 within the base 11 and the transmission shaft assembly 22 and surface treatment wheel 23 on the support frame 12, creating a staggered arrangement between the motor 21 and the surface treatment wheel 23. This lowers the overall center of gravity of the machine. Figure 4 In the illustrated embodiment, the motor 21 is located near the bottom of the base 11, thus effectively reducing the vibration generated by the motor 21 and the surface treatment wheel 23 during operation. At the same time, the triangular support structure formed by the first side plate 121, the second side plate 122 and the support plate 123 enhances the rigidity and stability of the frame 1, thereby effectively improving the quality of workpiece surface treatment and reducing noise during operation.

[0031] The surface treatment wheel in this application is existing technology, such as existing polishing wheels and sanding wheels. The type of surface treatment wheel can be changed according to the actual process.

[0032] See Figure 4 and Figure 5 The bottom of the support plate 123 is provided with at least one reinforcing plate 124 connecting the first side plate 121 and the second side plate 122, such as Figure 5 In the illustrated embodiment, two reinforcing plates 124 are provided, and the reinforcing plates 124 can improve the rigidity of the support frame 12.

[0033] See Figure 3 The frame 1 also includes a cover 125 connected to the ends of the first side plate 121 and the second side plate 122. The cover 125 covers the support plate 123. The cover 125 can prevent dust from entering, improve the life of each rotating component, and reduce the number of maintenance times.

[0034] See Figure 4 and Figure 5 The belt drive mechanism 3 includes a belt 31, and a tension pulley 32 is provided on the first side plate 121 and / or the second side plate 122 to abut against the outside of the belt 31. The tension pulley 32 can adjust the tension of the belt 31 to prevent the belt 31 from slipping.

[0035] See Figure 2 and Figure 3 There are two grinding devices 2, which are installed on opposite sides of the frame 1. The support plate 123 has a hole 126 in the middle for the belt 31 to pass through. The two grinding devices 2 are arranged opposite each other to balance the center of gravity of the whole machine.

[0036] The belt drive mechanism 3 involved in this application can adopt the prior art, which includes a belt 31 and two drive wheels coupled to the belt 31. The two drive wheels are respectively connected to the output end of the motor 21 and the drive shaft assembly 22, and the transmission connection between the output end of the motor 21 and the drive shaft assembly 22 is realized through the belt 31.

[0037] See Figure 1 , Figure 2 , Figure 6 and Figure 7 In one embodiment, the frame 1 is equipped with a coating mechanism 4 corresponding to each surface treatment wheel 23. The coating mechanism 4 is equipped with a material storage module 41 and a drive module 42 for driving the material storage module 41 to move relative to the surface treatment wheel 23. The material storage module 41 is constructed with a material storage tank 411 for storing consumables 100. The material storage tank 411 is open on the side near the surface treatment wheel. A clamping component 43 for fixing consumables 100 is arranged on the material storage tank 411.

[0038] In a specific embodiment, the drive module 42 includes a first feed module 421 and a second feed module 422 disposed on the first feed module 421, the material storage module 41 is disposed on the second feed module 422, the second feed module 422 is configured to control the material storage module 41 to move longitudinally toward or away from the surface treatment wheel 23, and the first feed module 421 is configured to control the second feed module 422 and the material storage module 41 to move in a direction parallel to the transmission shaft assembly 22. As a specific application scenario, the above-mentioned consumable 100 is solid wax, which is placed in the material storage tank 411, fixed by the clamping assembly 43, and extends downward out of the material storage tank 411. The clamping assembly 43 includes a clamping cylinder 431 disposed outside the material storage tank 411, and the output end of the clamping cylinder 431 extends into the material storage tank 411 and is provided with a clamping member 432 for pressing against or releasing the consumable 100. During operation, the second feed module 422 drives the material storage module 41 to move toward the surface treatment wheel 23 to push the wax toward the surface treatment wheel 23, and then the first feed module 421 drives the second feed module 422 and the material storage module 41 to feed horizontally, so as to apply wax onto the surface treatment wheel 23 to realize the polishing function. The above-mentioned first feed module 421 and second feed module 422 may be existing cylinder feed mechanisms. The arrangement of the applying mechanism 4 can increase the functions of the workpiece surface treatment equipment.

[0039] See Figure 2 , in an embodiment, the transmission shaft assembly 22 extends out of the frame 1, the surface treatment wheel 23 is mounted on the portion of the transmission shaft assembly 22 extending out of the frame 1, and the device further includes a shielding cover 13 at least partially enclosing the surface treatment wheel 23. The arrangement of the shielding cover 13 can prevent dust from splashing.

[0040] See Figure 2 , the shielding cover 13 is configured with a dust suction port 131, and the arrangement of the dust suction port 131 can be connected to an external dust suction device to avoid dust pollution to the environment.

[0041] See Figure 2 , the side portion of the shielding cover 13 is configured with an avoiding portion 132 communicating with its interior, and the arrangement of the avoiding portion 132 allows the workpiece to enter from the side portion so as to realize the treatment of the inner surface of the workpiece.

[0042] See Figure 1 , in an embodiment, the device further includes a workpiece fixing device 5 disposed on the outer side of the frame 1 corresponding to each grinding device 2. The workpiece fixing device 5 includes a loading mechanism 51 for fixing the workpiece and driving the workpiece to rotate, and a workpiece feed mechanism 52 for driving the loading mechanism 51 to feed. The workpiece feed mechanism 52 may be a screw slide driving mechanism in the prior art.

[0043] See Figure 1 and Figure 8The loading mechanism 51 is equipped with a mounting base 511, a workpiece rotating module 512 mounted on the mounting base 511, and a constant pressure cylinder 513 whose output end is connected to the mounting base 511. The output end of the constant pressure cylinder 513 can be floated and adjusted to maintain a constant pressure between the workpiece mounted on the workpiece rotating module 512 and the surface treatment wheel 23. This configuration dynamically compensates for errors caused by wear of the surface treatment wheel 23, ensuring constant grinding pressure, avoiding over-grinding or under-grinding, and guaranteeing the processing quality of the workpiece. The aforementioned floating adjustment means that when the pressure between the surface treatment wheel 23 and the workpiece is too high, the output end of the constant pressure cylinder 513 will adaptively retract; when the pressure between the surface treatment wheel 23 and the workpiece is too low, the output end of the constant pressure cylinder 513 will adaptively extend, so that the pressure between the surface treatment wheel 23 and the workpiece is within a preset range. The workpiece rotation module 512 can be a vacuum adsorption rotation mechanism in the prior art. The workpiece rotation module 512 is equipped with an adsorption end 512a and a power component 512b that drives the adsorption end 512a to rotate. The adsorption end 512a has a vacuum adsorption channel inside. The workpiece is adsorbed on the adsorption end 512a. The power component 512b drives the adsorption end to rotate, thereby driving the workpiece to rotate.
