Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a deburring device for excavator traction wheel brackets. Background Technology

[0002] As a type of heavy machinery widely used in various engineering construction fields, the traction wheel bracket of an excavator is a key component that ensures the stable operation and effective work of the excavator.

[0003] The manufacturing process of excavator traction wheel brackets typically involves various machining processes, such as casting, forging, cutting, and drilling. While these processes shape the traction wheel bracket, they inevitably produce burrs on its edges.

[0004] The presence of burrs can have several negative impacts on the excavator's tow wheel bracket. First, burrs affect the appearance quality of the tow wheel bracket, making its surface less smooth and flat, which does not meet the requirements of modern industrial products for a refined appearance.

[0005] Existing deburring methods have certain limitations in dealing with the burrs on excavator traction wheel brackets, making it difficult to meet the excavator manufacturing industry's demand for efficient, high-quality, and low-cost deburring of traction wheel brackets. Therefore, a deburring device for excavator traction wheel brackets is needed.

[0006] Chinese Patent Publication No. CN206465329U discloses an automatic deburring device, including a base, a cutting tool, a slide table, a first cylinder, a suction plate, and a controller. The base has a linear sliding groove. Two cutting tools are connected to the base via a fixing block. A slide rail is provided at the upper end of the base, and the slide table is located on the slide rail. The first cylinder is vertically positioned and connected to the slide table via a bracket. A drive motor is also provided on the slide table. The suction plate is connected to the piston rod of the first cylinder. An air pipe connector is provided at the upper edge of the suction plate. A suction cup is provided at the lower end of the suction plate, and the suction cup is connected to the air pipe connector through an internal air passage in the suction plate. An electrical control box is provided on the upper surface of the base, and an operation button is provided on the upper end of the electrical control box.

[0007] The aforementioned patent uses a controller to power the drive motor, which moves the slide table horizontally to the downstream end of the chute, thereby driving the plastic product through the deburring process of two blades. Although this can achieve the deburring effect, the deburred parts will still remain on the device, requiring subsequent cleaning and reducing the practicality of the device. Utility Model Content

[0008] The main purpose of this invention is to provide a deburring device for excavator traction wheel brackets, which can effectively solve the problem that the excavator traction wheel brackets cannot effectively clean the burrs produced by grinding.

[0026] 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.

[0027] like Figure 1 , Figure 2 and Figure 6As shown, a deburring device for an excavator traction wheel bracket includes a base 1, a housing 4 fixedly connected to the upper end of the base 1, a fixing device 3 installed on the front and rear walls of the housing 4, a fixing shell 7 fixedly connected to the middle of the upper end of the housing 4, a grinding device 6 installed on the middle of the fixing shell 7 and the rear wall of the housing 4, a chip blowing device 5 fixedly connected to the left side of the upper end of the housing 4, and a part body 2 placed in the middle of the upper end of the base 1.

[0028] Before implementing this device, the grinding device 6, the chip blowing device 5, and the fixing device 3 must be powered.

[0029] In the above process, the part body 2 is first placed on the upper part of the base 1, and then the fixing device 3 is started to operate so that the fixing device 3 clamps and fixes the part body 2. After fixing, the chip blowing device 5 and the grinding device 6 are started in sequence so that the grinding device 6 moves downward. When it moves to the position where the part body 2 needs to be ground, the grinding device 6 stops moving and then starts to rotate to grind the rough edges of the part body 2. Then the chip blowing device 5 blows the ground rough edges out of the part body 2 and collects and stores them.

[0030] In the above process, after the grinding is completed, the grinding device 6 is turned off and rotated. Then, the grinding device 6 is moved upward to separate the grinding device 6 from the part body 2. Then, the fixing devices 3 are removed one by one to take out the part body 2.

[0031] In the above, the chip blowing device 5 consists of a blower fan, a chip storage bin, and a chip collection box. The blower fan is fixedly connected to the front right end of the fixed shell 7, the chip storage bin is fixedly connected to the upper left end of the outer shell 4, and the chip collection box is slidably connected to the lower front side of the chip storage bin. When the blower fan is started, it rotates and blows the polished burrs into the chip storage bin, and then into the chip collection box, so that the burrs polished by the polishing device 6 will not fall into the part body 2. When the chip collection box is full, the chip collection box can be removed and the burrs inside can be emptied out.

[0032] Furthermore, in order to achieve the purpose of clamping and fixing the part body 2 by the fixing device 3, refer to... Figure 3 and Figure 4 The fixing device 3 includes a stepper motor 33 and four fixing plates 35. The stepper motor 33 is fixedly connected to the right side of the upper rear part of the base 1. A worm gear 31 is fixedly connected to the output end of the stepper motor 33. Support plates 32 are fixedly connected to the left and right sides of the outer surface of the worm gear 31. The four fixing plates 35 are respectively fixedly connected to the left and right sides of the front and rear parts of the upper part of the base 1. The two fixing plates 35 located on the same side are rotatably connected to a clamping mechanism 36 at their close ends. Worm wheels 34 are fixedly connected to the upper rear part of the two clamping mechanisms 36.

[0033] The worm 31 is respectively engaged with two worm gears 34;

[0034] The clamping mechanism 36 includes two rotating rods 364, which are rotatably connected to the upper and lower parts of the two fixed plates 35 located on the same side and close to each other. A spur gear 365 is fixedly connected to the rear part of the outer surface of each of the two rotating rods 364. A connecting rod 2 363 is fixedly connected to the middle part of the outer surface of each of the two rotating rods 364. A connecting rod 1 362 is rotatably connected to the part of the two connecting rod 2 363 away from the rotating rods 364. A clamping plate 361 is rotatably connected to the part of the two connecting rod 1 362 away from the connecting rod 2 363.

[0035] Two clamping plates 361 are slidably connected to the upper left and right sides of the base 1, respectively. Two worm gears 34 are fixedly connected to the rear edge of the outer surface of the two rotating rods 364 located on the upper side, and the two spur gears 365 mesh with each other.

[0036] In the above process, the stepper motor 33 is started to rotate. When the stepper motor 33 rotates, it drives the worm gear 31 to rotate through the coupling. When the worm gear 31 rotates, it drives the worm wheel 34 to rotate through its meshing relationship. The worm wheel 34 then transmits power to the upper rotating rod 364, causing the rotating rod 364 to rotate. The upper rotating rod 364 then transmits power to the spur gear 365 connected to it, causing it to rotate. When the upper spur gear 365 rotates, it drives the lower spur gear 365 to rotate through its meshing relationship. The lower spur gear 365 rotates, which in turn drives the lower rotating rod 364 to rotate. When the rotating rod 364 rotates, it drives the upper connecting rod 363 to rotate counterclockwise and the lower connecting rod 363 to rotate clockwise. Through its rotational connection with the connecting rod 362, the connecting rod 362 gradually becomes horizontal, causing the clamping plate 361 to move away from the closer part. This clamping plate 361 clamps and fixes the part body 2, preventing the part body 2 from shifting during grinding and improving the grinding effect of the grinding device 6.

[0037] Furthermore, in order to achieve the purpose of grinding the part body 2 by the grinding device 6, refer to... Figure 5 The grinding device 6 includes a convex plate 61, which slides on the middle of the rear wall of the fixed shell 7 and the outer shell 4. Guide rods 63 are slidably connected to the left and right sides of the rear part of the convex plate 61. An electric telescopic cylinder 62 is fixedly connected to the middle side of the rear part of the lower end of the convex plate 61. A rotary motor 64 is fixedly connected to the front part of the lower end of the convex plate 61. A grinding wheel 65 is fixedly connected to the output end of the rotary motor 64.

[0038] Two guide rods 63 are fixedly connected to the top wall of the fixed shell 7 and the left and right parts of the upper end of the base 1, respectively.

[0039] In the above process, the electric telescopic cylinder 62 is activated to extend and retract, causing the convex plate 61 to move downward. When the rotating motor 64 moves to the part body 2 where grinding is required, the electric telescopic cylinder 62 stops moving and then the rotating motor 64 is activated to rotate, causing the rotating motor 64 to drive the grinding wheel 65 to rotate together through the coupling, so that the grinding wheel 65 grinds the burrs on the part body 2 and removes the burrs.

[0040] As described above, the guide rod 63 can ensure the stability of the convex plate 61 during movement, so that the convex plate 61 can be subjected to uniform force.

[0041] It should be noted that the specific installation method, circuit connection method and control method of the rotary motor 64, electric telescopic cylinder 62 and stepper motor 33 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
