Description

Technical Field

[0001] This utility model belongs to the field of automotive technology, specifically relating to a deburring mechanism for the body of a spring brake chamber. Background Technology

[0002] The spring brake chamber is part of the automotive braking system. It is generally installed on the drive axle of the car and its function is to provide braking torque to the car. The combined spring brake chamber is used to provide braking driving force for the wheel brakes. It consists of two parts: a diaphragm chamber for service braking and a spring chamber for auxiliary braking and parking braking. The spring chamber is characterized by its overtravel function and is equipped with a mechanical brake release device. During the production process, the surface of the spring brake chamber needs to be processed by a deburring mechanism.

[0003] Currently, deburring mechanisms lack automatic correction and positioning mechanisms. Typically, before deburring the inner body of the spring brake chamber, it needs to be manually limited and fixed. However, due to the close proximity of the processing position to the deburring mechanism, there are certain operational risks, and continuous processing is cumbersome, resulting in limited convenience in actual use. Therefore, this paper proposes a deburring mechanism for the inner body of the spring brake chamber to incorporate an automatic correction and positioning mechanism. Utilizing a sleeve and limiting method, the mechanism automatically corrects and positions the inner body before deburring, improving both operational convenience and safety, thereby enhancing the overall performance. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a deburring mechanism for the body of a spring brake air chamber, so as to automatically correct and position it before deburring by means of sleeve and limiting, thereby improving the use effect.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0006] A deburring mechanism for a spring brake air chamber includes a base, a processing table, and a sliding frame. The top of the base is bolted to the processing table. A guide column is bolted to one side of the top of the processing table, and a support column is bolted to the other side of the top of the processing table. The sliding frame is fitted around both the guide column and the support column. A guide positioning assembly is provided at the bottom of the sliding frame, and a dust collection assembly is provided at the bottom of the processing table.

[0007] The guide positioning component includes a conical sleeve, which includes a vertical section and a flared section. The surfaces of both the vertical section and the flared section are provided with ball grooves, and ball bearings are rolled within the ball grooves.

[0008] By adopting the above technical solution, an automatic correction and positioning mechanism can be added. Before deburring, the spring brake chamber is positioned by vertical sliding, thereby replacing the traditional manual clamping and fixing method. This not only improves the convenience of operation, but also greatly improves the safety of use.

[0009] Specifically, the dust collection assembly includes a dust collection tank, which is bolted to the bottom of the processing table. A fan is bolted to the bottom of the dust collection tank, and the air inlet of the fan is located inside the dust collection tank. A filter plate is fixedly installed inside the dust collection tank via a slot.

[0010] By adopting the above technical solution, an auxiliary dust collection mechanism can be added to collect the dust generated during the deburring process by means of suction and material guiding, thereby reducing pollution of the working environment and improving the actual use effect.

[0011] Specifically, the bottom of the sliding frame is bolted to a protective sleeve, and the bottom of the sliding frame is located inside the protective sleeve and a rotating shaft is mounted on it via a bearing. One end of the rotating shaft is bolted to a grinding wheel, and the top of the sliding frame is bolted to a drive motor, which is connected to the rotating shaft via a drive shaft.

[0012] By adopting the above technical solution, the sheath, rotating shaft, grinding wheel and drive motor can be used to deburr the body of the spring brake air chamber.

[0013] Specifically, the dust collection tank has discharge ports on both sides, and the processing table has guide holes on its surface, which are connected to the dust collection tank.

[0014] By adopting the above technical solution, the discharge port facilitates the discharge of dust collected in the dust collection tank, and the guide hole facilitates the introduction of dust generated during deburring into the dust collection tank.

[0015] Specifically, a guide rod is bolted to the top of the sheath, and the guide rod passes through the tapered sleeve through a pre-drilled hole. The outer periphery of the guide rod is connected to a compression spring at the top of the tapered sleeve.

[0016] By adopting the above technical solution, the guide rod and the compression spring can use elastic force to push the conical sleeve to slide downward, so that it can be pre-fitted and limited to the spring brake air chamber.

[0017] Specifically, a lead screw is mounted on the inner side of the guide post via a bearing, and a corresponding ball slider is sleeved around the lead screw. The ball slider is connected to a sliding frame via bolts, and a servo motor is connected to the top of the guide post via bolts. The servo motor is connected to the lead screw via a drive shaft.

[0018] By adopting the above technical solution, the servo motor drives the lead screw to rotate, and the ball block can drive the sliding frame to move vertically, adjusting the working height and position of the deburring mechanism.

[0019] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0020] This invention relates to a deburring mechanism for the inner body of a spring brake chamber. Through the inclusion of a processing table, guide column, sliding frame, conical sleeve, vertical section, flared section, ball groove, and ball bearings, an automatic correction and positioning mechanism is added. Before deburring, the spring brake chamber is positioned using vertical sliding, replacing the traditional manual clamping and fixing method. This not only improves operational convenience but also significantly enhances safety. Furthermore, the deburring mechanism for the inner body of a spring brake chamber incorporates a dust collection trough, exhaust fan, filter plate, discharge port, and guide hole, providing an auxiliary dust collection mechanism. Using a baffle and suction method, the dust generated during deburring is effectively collected and treated, reducing environmental pollution and improving practical performance.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To facilitate the use of socketing and limiting methods, automatic pre-calibration and positioning are performed before deburring, thereby improving the performance. Figure 1-4 As shown, the spring brake chamber deburring mechanism of this utility model includes a base 1, a processing table 2, and a sliding frame 5. The top of the base 1 is bolted to the processing table 2. One side of the top of the processing table 2 is bolted to a guide column 3, and the other side of the top of the processing table 2 is bolted to a support column 4. The sliding frame 5 is sleeved around both the guide column 3 and the support column 4. A guide positioning component 6 is provided at the bottom of the sliding frame 5, and a dust collection component 7 is provided at the bottom of the processing table 2.

[0030] The guide positioning component 6 includes a conical sleeve 601, which includes a vertical section 602 and a flared section 603. The surfaces of the vertical section 602 and the flared section 603 are provided with ball grooves 604, and ball balls 605 are rolled in the ball grooves 604.

[0031] In use, the automatic correction and positioning mechanism can be added through the processing table 2, guide column 3, support column 4, sliding frame 5, conical sleeve 601, vertical section 602, flared section 603, ball groove 604 and ball 605. Before deburring, the spring brake air chamber is positioned by vertical sliding, thereby replacing the traditional manual clamping and fixing method. This not only improves the convenience of operation, but also greatly improves the safety of use.

[0032] To improve the quality of the work environment, for example, such as Figure 2 , Figure 5 As shown, the present invention also includes a dust collection assembly 7 comprising a dust collection trough 701, which is bolted to the bottom of the processing table 2. A fan 702 is bolted to the bottom of the dust collection trough 701, and the air inlet of the fan 702 is located inside the dust collection trough 701. A filter plate 703 is fixedly installed inside the dust collection trough 701 by means of a slot.

[0033] In use, the dust collection tank 701, the exhaust fan 702 and the filter plate 703 can be used to add an auxiliary dust collection mechanism. By using suction and material guiding, the dust generated during the deburring process can be recovered, reducing the pollution of the working environment and improving the actual use effect.

[0034] For example, such as Figure 3As shown, the present invention also includes a protective sleeve 501 bolted to the bottom of the sliding frame 5, a rotating shaft 502 mounted on the bottom of the sliding frame 5 inside the protective sleeve 501 via a bearing, a grinding wheel 503 bolted to one end of the rotating shaft 502, a drive motor 504 bolted to the top of the sliding frame 5, and the drive motor 504 connected to the rotating shaft 502 via a drive shaft.

[0035] During use, the inner body of the spring brake chamber can be deburred through the sheath 501, rotating shaft 502, grinding wheel 503 and drive motor 504.

[0036] For example, such as Figure 2 , 5 As shown, the present invention also includes a discharge port 704 on both sides of the dust collection tank 701, and a guide hole 201 on the surface of the processing table 2, which is connected to the dust collection tank 701.

[0037] During use, the dust collected in the dust collection tank 701 can be discharged through the discharge port 704, and the dust generated during deburring can be guided into the dust collection tank 701 through the guide hole 201.

[0038] For example, such as Figure 3 As shown, the present invention also includes a guide rod 505 bolted to the top of the sheath 501, and the guide rod 505 passes through the tapered sleeve 601 through a pre-drilled hole. The outer periphery of the guide rod 505 is located at the top of the tapered sleeve 601 and is connected to a compression spring 506.

[0039] In use, the guide rod 505 and the compression spring 506 can be used to push the conical sleeve 601 downward to pre-fit and limit the spring brake air chamber.

[0040] For example, such as Figure 6 As shown, the present invention also includes a lead screw 301 mounted on the inner side of the guide post 3 via a bearing, a corresponding ball slider 302 sleeved around the lead screw 301, and the ball slider 302 connected to the sliding frame 5 via bolts. The top of the guide post 3 is connected to the servo motor 303 via bolts, and the servo motor 303 is connected to the lead screw 301 via a drive shaft.

[0041] In use, the servo motor 303 drives the lead screw 301 to rotate, and the ball slider 302 can drive the sliding frame 5 to move vertically, adjusting the working height and position of the deburring mechanism.

[0042] In use, the operator first places the spring brake chamber on the processing table 2, manually turns on the servo motor 303 to drive the lead screw 301 to rotate, and uses the ball slider 302 to slide the sliding frame 5 vertically downward, so that the grinding wheel 503 gradually enters the spring brake chamber. Driven by the drive motor 504, the deburring action is performed. Before the deburring process, under the elastic force of the compression spring 506, the balls 605 on the inner side of the flared section 603 and the vertical section 602 of the conical sleeve 601 contact the outer surface of the spring brake chamber in sequence to assist in the fitting and limiting process, thereby replacing the traditional manual operation method, which not only improves the convenience of operation, but also makes it safer and more reliable.

[0043] While performing deburring, the exhaust fan 702 can be manually turned on. The negative pressure generated by the suction will draw the dust generated during deburring inside the sheath 501 into the dust collection tank 701 for recycling through the material guide hole 201, thereby reducing pollution in the working environment and improving the actual use effect. The overall structure is simple, the cost is low, and the use is more reasonable and reliable.
