Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to an automobile suspension spring end surface grinding device. Background Art

[0002] When the automobile suspension spring is in use, its two ends need to be fixed to the automobile suspension. In order to facilitate the opening and fixing, it is usually necessary to use a spring end face grinding machine to grind its end face. When grinding, one end of the spring needs to be squeezed so that the other end is close to the grinding disk for grinding.

[0003] When the existing spring grinding machine is in use, a grinding disc is generally set on one side of the grinding frame, and the spring is put into the grinding disc for grinding by rotating the grinding frame. This makes the grinding area smaller during actual processing. In order to achieve a good grinding effect, more time is required, resulting in low grinding efficiency and inability to grind springs of different lengths. At the same time, the debris generated by grinding is not easy to collect. Usually, a rubber curtain is set to block the grinding area. The grinding area needs to be cleaned after grinding, which is more troublesome. For this purpose, a vehicle suspension spring end face grinding device is provided to solve the above problems.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] The embodiment of the present application provides an automobile suspension spring end surface grinding device, which solves the problems of low grinding efficiency, inability to grind springs of different lengths, and difficulty in collecting grinding debris in existing spring grinding machines during processing.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The embodiment of the utility model discloses a spring end surface grinding device for an automobile suspension spring.

[0027] According to the attached Figure 1-6 As shown, it includes a spring grinding machine 1 and an adjustable spring feeding mechanism 2 installed on the top of the spring grinding machine 1. A grinding mechanism 5 is provided at the bottom of the adjustable spring feeding mechanism 2. The adjustable spring feeding mechanism 2 includes a rotating frame 21, a movable cylinder 22, a top stop frame 24 and a fixed cylinder 25.

[0028] The rotating frame 21 is rotatably connected to the top of the spring grinding machine 1, the fixed cylinder 25 is fixedly connected to the inside of the rotating frame 21, the movable cylinder 22 is slidably arranged on the top outer wall of the fixed cylinder 25, and the top retaining frame 24 is installed on the top of the movable cylinder 22;

[0029] The bottom of the rotating frame 21 is fixedly connected to a passive gear ring 28, and the top of the spring grinding machine 1 is fixedly installed with a rotation drive motor 23. The internal rotation of the spring grinding machine 1 is connected to a transmission gear 29. A transmission chain is installed between the rotation drive motor 23 and the transmission gear 29. The passive gear ring 28 is meshed with the transmission gear 29. The rotation drive motor 23 drives the transmission gear 29 to rotate through the transmission chain, and the transmission gear 29 drives the passive gear ring 28 to rotate, thereby rotating the entire rotating frame 21.

[0030] The top of the movable cylinder 22 is fixedly connected to the synchronous carrier 26, and the external rotation of the synchronous carrier 26 is connected to the limit bracket 211. The top of the spring grinding machine 1 is rotatably connected to the support ring 210, and the top of the support ring 210 is fixedly welded with a support column 27. The limit bracket 211 and the top block 24 are fixedly installed on the outer surface of the support column 27 by bolts. The height is adjusted by moving the limit bracket 211 and the top block 24 up and down on the outer surface of the support column 27, and then fixed with bolts to adapt to springs of different heights.

[0031] A lower hopper 4 is fixedly installed on one side of the bottom of the spring grinding machine 1, and a slag receiving tube 3 is threadedly connected to the other side of the bottom of the spring grinding machine 1. The top of the lower hopper 4 faces a group of fixed tubes 25. The polished spring is unloaded through the lower hopper 4, and the slag receiving tube 3 is used to receive the grinding waste.

[0032] During use, the height is adjusted by moving the limit bracket 211 and the top block 24 up and down on the outer surface of the support column 27, and then fixed with bolts to accommodate springs of different heights. The springs are placed in a set of fixed cylinders 25 at the opening of the top block 24, and then the rotary drive motor 23 is activated, which drives the entire rotating frame 21 to rotate. The rotating frame 21 drives the fixed cylinders 25, the movable cylinder 22, and the synchronous carrier 26 to rotate, so that the fixed cylinders 25 filled with springs move below the top block 24, compressing the springs so that the bottom of the springs contact the grinding plate 53.

[0033] The grinding mechanism 5 includes a plurality of grinding discs 53 arranged at the bottom of the fixed cylinder 25 . A grinding drive motor 51 is fixedly installed in the middle of the spring grinding machine 1 . The grinding discs 53 are in transmission connection with the grinding drive motor 51 .

[0034] The output end of the grinding drive motor 51 is fixedly connected to the driving gear ring 52, and the bottom of the grinding plate 53 is fixedly installed with a passive gear 55. The driving gear ring 52 is engaged with the passive gear 55. The grinding drive motor 51 drives the driving gear ring 52 to rotate, and the driving gear ring 52 drives multiple passive gears 55 to rotate, thereby causing multiple grinding plates 53 to rotate at high speed.

[0035] An annular groove 6 is provided inside the spring grinding machine 1, and a support frame 54 is fixedly connected to the inner top of the annular groove 6. A driven gear 55 is rotatably connected to the inside of the support frame 54. The surfaces of the driven gear 55 and the grinding sheet 53 are hollow. During the grinding process, the debris generated will fall downward into the annular groove 6 through the hollow grooves on the surfaces of the driven gear 55 and the grinding sheet 53 under the action of gravity, making it easier for the debris to fall.

[0036] A flexible scraper 56 is fixedly installed at the bottom of the driving gear ring 52, and the flexible scraper 56 is slidably connected to the inner bottom of the annular groove 6. The top of the slag collecting tube 3 is connected to the inside of the annular groove 6. When the driving gear ring 52 rotates, the flexible scraper 56 at its bottom is synchronously driven to rotate. When the flexible scraper moves inside the annular groove 6, it pushes the impurities at the inner bottom in a direction. When it is pushed to the position of the slag collecting tube 3, the slag falls downward, completing the debris collection.

[0037] The grinding drive motor 51 drives the driving gear ring 52 to rotate, and the driving gear ring 52 drives multiple passive gears 55 to rotate, so that multiple grinding discs 53 rotate at high speed, grinding the bottom end of the spring inside each group of fixed cylinders 25, and the debris generated by grinding falls down to the inside of the annular groove 6, and is scraped by the flexible scraper 56, so that the debris falls into the inside of the slag collecting cylinder 3 to complete the grinding and automatic collection of debris.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
