Description

Technical Field

[0001] This utility model relates to the field of precision machining equipment, and in particular to a dust removal device for precision machining. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. It can be divided into cutting and pressure processing according to the difference in processing methods. After machining, a lot of dust will be generated on the surface of the workpiece, which requires the use of dust removal devices to treat the dust on the workpiece surface. However, most of the existing dust removal devices in the technical solution treat the dust on the workpiece surface directly by using a fan. This dust removal method is too simple and cannot ensure that the dust on the workpiece surface can be completely removed, which will affect the quality of subsequent processing of the workpiece. Utility Model Content

[0003] This application provides a dust removal device for precision machining, which solves the technical problem that most existing dust removal devices directly treat the dust on the workpiece surface using a fan. This dust removal method is too simple and cannot ensure that the dust on the workpiece surface can be completely removed, which will affect the quality of subsequent workpiece processing.

[0004] The technical solution adopted in the embodiments of this application is as follows:

[0005] A dust removal device for precision machining includes a base, a support frame mounted on the base, a dust removal mechanism for cleaning dust from the surface of a workpiece, a positioning component for fixing the workpiece, a first drive device for driving the dust removal mechanism to rise and fall, and a sliding device for driving the dust removal mechanism to slide back and forth. Two sets of symmetrically arranged positioning components are mounted on the base. The sliding device is mounted on the support frame. The first drive device is mounted on the sliding end of the sliding device. The dust removal mechanism is mounted on the drive end of the first drive device.

[0006] A further technical solution is as follows: the dust removal mechanism includes a fan body, a mounting base installed on the driving end of the first driving device, a brush for cleaning dust from the workpiece surface, and a buffer assembly for buffering the brush; the fan body is installed on the mounting base, and the air outlet of the fan body faces the base; the brush is provided at both ends of the fan body; both sets of brushes are connected to the mounting base through several sets of buffer assemblies arranged in a linear array; the buffer assembly includes a spring and a telescopic rod for limiting the spring; the spring is arranged around the telescopic rod; the telescopic end of the telescopic rod is connected to the brush; the other end of the telescopic rod is connected to the mounting base.

[0007] A further technical solution is as follows: the positioning component includes a damping block, a clamping plate for clamping the workpiece, and a second driving device mounted on the base; the clamping plate is disposed on the driving end of the second driving device; and a plurality of damping blocks are arranged in a linear array on the clamping plate.

[0008] A further technical solution is as follows: the sliding device includes a slider that slides on the support frame, a threaded rod for driving the slider to move, a ball bearing disposed at one end of the support frame, and a third driving device installed at the other end of the support frame; the slider is threadedly connected to the threaded rod; the first driving device is installed on the slider; one end of the threaded rod is connected to the inner ring of the ball bearing; the other end of the threaded rod is connected to the output shaft of the third driving device.

[0009] A further technical solution is that both the first driving device and the second driving device are cylinders.

[0010] A further technical solution is that the third driving device is a motor.

[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0012] 1. Due to the use of a base, support frame, dust removal mechanism, positioning components, first drive device, and sliding device, when it is necessary to clean dust from the workpiece surface, the workpiece is first placed at the center of the top of the base. Then, the second drive device in both sets of positioning components extends simultaneously, driving both sets of clamping plates to move towards the workpiece. When the two sets of clamping plates simultaneously abut against both ends of the workpiece, the workpiece is fixed. Several sets of damping blocks arranged in a linear array are fixedly connected to the clamping plates, which increases the friction between the clamping plates and the workpiece, thereby improving the fixing effect of the two sets of clamping plates on the workpiece. After the workpiece is fixed, the first drive device extends to drive the dust removal mechanism to move downward, causing the two sets of brushes in the dust removal mechanism to fit tightly against the workpiece surface. Then, the fan body in the dust removal mechanism starts working, and at the same time, the sliding end of the sliding device drives the first drive device to slide back and forth. At this time, the two sets of brushes will fit tightly against the workpiece surface and slide back and forth due to the elastic force of the spring. The combined action of the brush and the blower effectively and thoroughly cleans dust adhering to the workpiece surface. Once the dust is removed, the blower stops operating, and the first drive unit retracts, moving the dust removal mechanism away from the workpiece surface. Then, the second drive unit in the two sets of positioning components retracts, moving the two clamping plates away from the workpiece. The cleaned workpiece can then be removed. The entire operation is simple, reliable, and convenient for workers.

[0013] 2. Due to the use of a slider, threaded rod, ball bearings and a third drive device, the threaded rod is driven to rotate through the output shaft of the third drive device. Since the slider slides on the support frame and is threadedly connected to the threaded rod, when the threaded rod rotates, it can drive the slider to slide back and forth along the support frame, thereby driving the dust removal mechanism to move back and forth.

[0020] This application provides a dust removal device for precision machining, which solves the technical problem that most existing dust removal devices directly treat the dust on the workpiece surface using a fan. This dust removal method is too simple and cannot ensure that the dust on the workpiece surface can be completely removed, which will affect the quality of subsequent workpiece processing.

[0021] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] A dust removal device for precision machining, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a base 1, a support frame 2 mounted on the base 1, a dust removal mechanism 3 for cleaning dust from the workpiece surface, a positioning component 4 for fixing the workpiece, a first drive device 5 for driving the dust removal mechanism 3 to rise and fall, and a sliding device 6 for driving the dust removal mechanism 3 to slide back and forth. Two sets of symmetrically arranged positioning components 4 are mounted on the base 1. The sliding device 6 is mounted on the support frame 2. The first drive device 5 is mounted on the sliding end of the sliding device 6. The dust removal mechanism 3 is mounted on the driving end of the first drive device 5.

[0024] The support frame 2 is fixedly installed on the top of the base 1. Two sets of symmetrically arranged positioning parts 4 are fixedly connected to the top of the base 1. The sliding device 6 is fixedly installed on the top of the support frame 2. The first drive device 5 is fixedly installed on the sliding end of the sliding device 6. The first drive device 5 is preferably a cylinder. The dust removal mechanism 3 is fixedly connected to the driving end of the first drive device 5.

[0025] The dust removal mechanism 3 includes a fan body 31, a mounting base 32 installed on the drive end of the first drive device 5, brushes 33 for cleaning dust from the workpiece surface, and buffer components 34 for cushioning the brushes 33. The fan body 31 is mounted on the mounting base 32, with the air outlet of the fan body 31 facing the base 1. Brushes 33 are provided at both ends of the fan body 31. Both sets of brushes 33 are connected to the mounting base 32 by several sets of buffer components 34 arranged in a linear array. The buffer components 34 include a spring 341 and a telescopic rod 342 for limiting the spring 341. The spring 341 is arranged around the telescopic rod 342. The telescopic end of the telescopic rod 342 is connected to the brush 33. The other end of the telescopic rod 342 is connected to the mounting base 32.

[0026] Mounting base 32 is fixedly mounted on the drive end of the first drive device 5. Fan body 31 is fixedly mounted on mounting base 32. Both sets of brushes 33 are fixedly connected to mounting base 32 via several sets of buffer components 34 arranged in a linear array. The telescopic end of telescopic rod 342 is fixedly connected to brush 33. The other end of telescopic rod 342 is fixedly connected to mounting base 32. One end of spring 341 is fixedly connected to brush 33. The other end of spring 341 is fixedly connected to mounting base 32. Telescopic rod 342 is used to prevent deformation of spring 341, thus providing a certain degree of protection for spring 341.

[0027] The positioning component 4 includes damping blocks 41, a clamping plate 42 for holding the workpiece, and a second driving device 43 mounted on the base 1. The clamping plate 42 is disposed on the driving end of the second driving device 43. Several sets of damping blocks 41 are arranged in a linear array on the clamping plate 42.

[0028] The second drive unit 43 is fixedly mounted on the top of the base 1. The second drive unit 43 is preferably a cylinder. The clamping plate 42 is fixedly connected to the drive end of the second drive unit 43. Several sets of damping blocks 41 arranged in a linear array are fixedly connected to the clamping plate 42.

[0029] Due to the configuration of the base 1, support frame 2, dust removal mechanism 3, positioning components 4, first drive device 5, and sliding device 6, when it is necessary to clean the dust on the surface of the workpiece, the workpiece is first placed at the top center of the base 1. Then, the driving ends of the second drive devices 43 in the two sets of positioning components 4 extend simultaneously, driving the two sets of clamping plates 42 to move towards the workpiece. When the two sets of clamping plates 42 simultaneously abut against both ends of the workpiece, the workpiece can be fixed. Several sets of damping blocks 41 arranged in a linear array are fixedly connected to the clamping plates 42, which increases the friction between the clamping plates 42 and the workpiece, thereby improving the fixing effect of the two sets of clamping plates 42 on the workpiece. Once the workpiece is in a fixed position, the first driving device 5 extends, driving the dust removal mechanism 3 downwards. This causes the two sets of brushes 33 in the dust removal mechanism 3 to fit tightly against the workpiece surface. Then, the fan body 31 in the dust removal mechanism 3 starts working, simultaneously driving the first driving device 5 back and forth via the sliding end of the sliding device 6. During this back-and-forth movement, the two sets of brushes 33, due to the elastic force of the spring 341, remain tightly against the workpiece surface. Through the cooperation of the brushes 33 and the fan body 31, the dust adhering to the workpiece surface can be effectively and thoroughly cleaned. After the dust adhering to the workpiece surface is cleaned, the fan body 31 stops operating, and the first driving device 5 retracts, moving the dust removal mechanism 3 away from the workpiece surface. Then, the second driving devices 43 in the two sets of positioning parts 4 retract, moving the two sets of clamping plates 42 away from the workpiece. The cleaned workpiece can then be removed. The entire operation is simple, reliable, and convenient for operators.

[0030] like Figure 5 As shown, the sliding device 6 includes a slider 61 that slides on the support frame 2, a threaded rod 62 for moving the slider 61, a ball bearing 63 disposed at one end of the support frame 2, and a third drive device 64 mounted at the other end of the support frame 2. The slider 61 is threadedly connected to the threaded rod 62. The first drive device 64 is mounted on the slider 61. One end of the threaded rod 62 is connected to the inner ring of the ball bearing 63. The other end of the threaded rod 62 is connected to the output shaft of the third drive device 64.

[0031] A ball bearing 63 is fixedly connected to one end of the support frame 2. The third drive device 64 is preferably a motor. The third drive device 64 is fixedly installed at the other end of the support frame 2. The first drive device 5 is fixedly installed at the bottom end of the slider 61. One end of the threaded rod 62 is fixedly connected to the inner ring of the ball bearing 63. The other end of the threaded rod 62 is fixedly connected to the output shaft of the third drive device 64.

[0032] Because of the arrangement of slider 61, threaded rod 62, ball bearing 63 and third drive device 64, the output shaft of the third drive device 64 drives the threaded rod 62 to rotate. Since slider 61 slides on support frame 2 and is threadedly connected to threaded rod 62, when threaded rod 62 rotates, it can drive slider 61 to slide back and forth along support frame 2, thereby driving dust removal mechanism 3 to move back and forth.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
