[0002] At present, with the booming development of the automotive industry, the manufacturing process of automotive parts continues to improve, and the requirements for processing accuracy and production efficiency are becoming increasingly stringent. As the core equipment in the milling process of automotive parts, the performance of its supporting jig plays a decisive role in the entire processing flow.

[0003] Traditional jigs for milling machine processing of automotive parts mostly use bolt fastening or pressure plate pressing to fix workpieces. In actual operation, whenever a new automotive part is installed, the operator needs to spend a lot of time accurately aligning the workpiece and achieve fastening by screwing bolts multiple times; at the same time, after the jig completes the processing of parts, a large amount of metal chips and cutting fluid mixture are extremely likely to remain on the surface of its platform. Due to the structural design of the jig not fully considering the chip removal requirements, the accumulated chips are difficult to quickly clean up, which not only affects the positioning accuracy of subsequent workpieces, but also may cause jig wear due to chip extrusion, reduce the service life of the equipment, and increase maintenance costs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manners, structures, features, and effects of the present invention as follows.

[0018] The following will, in conjunction with the accompanying drawings, detail the technical solutions provided by each embodiment of the present invention.

[0019] Refer to Figures 1 to 6 As shown, an embodiment of the present invention provides a quick installation fixture for milling machine processing of automotive parts, including a workbench 1, a fixture assembly 2, and a tilting assembly 3; The tilting assembly 3 includes mounting seats 32 fixedly installed on the workbench 1 near both ends, and a rotating shaft 33 is rotatably installed between the two groups of mounting seats 32. A connecting frame 34 is fixedly installed on the rotating shaft 33. A fixture platform 31 is fixedly installed on the bottom surface of the connecting frame 34. The fixture platform 31 is adapted to rotate along the axis of the rotating shaft 33 through the connecting frame 34, so that the fixture platform 31 is in an inclined state. The workbench 1 has a bottom table 12, and a collection box 38 is slidably installed on the bottom table 12. At the same time, a driving part that rotates with the rotating shaft 33 and synchronously pushes out the collection box 38 is installed on the bottom table 12; The fixture assembly 2 includes a clamping unit installed on the fixture platform 31 for clamping the four sides of the automotive parts, and a limiting unit that is located at the four corners of the automotive parts on the fixture platform 31 and is used for pressing the automotive parts.

[0020] As Figures 1 - 3 shown, specifically, the clamping unit includes four groups of first cylinders 21 fixedly installed on the fixture platform 31 in pairs and symmetrically. A clamping plate 22 is fixedly installed at the output end of the first cylinder 21. An anti-slip pad is provided at the contact position between the clamping plate 22 and the automotive parts. The anti-slip pad can be made of silica gel; The first cylinders 21 are started simultaneously. The output end of the first cylinder 21 extends or contracts, driving the clamping plate 22 fixedly connected thereto to move towards or away from each other. When it is necessary to clamp the automotive parts, the first cylinder 21 pushes the clamping plate 22 to gradually approach the workpiece until the clamping plate 22 contacts and clamps the automotive parts. Since an anti-slip pad made of silica gel is provided at the contact position between the clamping plate 22 and the automotive parts, the friction force is increased, which can effectively prevent the automotive parts from being displaced due to external forces such as milling forces during the processing, ensure the processing accuracy, and achieve stable and reliable clamping of the automotive parts.

[0021] As Figures 2 - 3As shown, specifically, the limiting unit includes a fixed platform 23 fixedly mounted on the fixture platform 31 and located at the four corners of the automobile parts, a right-angle seat 24 is fixedly mounted on the fixed platform 23, and a second cylinder 25 is fixedly mounted on the right-angle seat 24, the telescopic end of the second cylinder 25 passes through the right-angle seat 24 and the fixed platform 23 in sequence, and a connecting rod 27 is movably mounted on the telescopic end of the second cylinder 25, one end of the connecting rod 27 has a pressing seat 29, and an articulated seat 26 is fixedly mounted on one side of the fixed platform 23 close to the pressing seat 29, and a connecting rod 28 is movably mounted between the articulated seat 26 and the connecting rod 27, and both ends of the connecting rod 28 are movably connected to the articulated seat 26 and the connecting rod 27; When the limiting unit is working, the second cylinder 25 on the fixed platform 23 at the four corners of the automobile parts on the clamp platform 31 is started. The telescopic end of the second cylinder 25 penetrates the right-angle seat 24 and the fixed platform 23, driving the movably installed connecting rod 27 to make linear motion. At the same time, due to the connecting rod 28 that is movably connected between the hinge seat 26 and the connecting rod 27 on the fixed platform 23, when the connecting rod 27 moves, the connecting rod 28 rotates around the hinge seat 26, so that the connecting rod 27 performs angle conversion movement with the hinge seat 26 as the fulcrum. When it is necessary to fix the automobile parts, the telescopic end of the second cylinder 25 is extended, and the connecting rod 28 is linked through the connecting rod 27 to allow the clamping seat 29 to approach and clamp the four corners of the parts to limit their up and down jumping and displacement; after the processing is completed, the telescopic end of the second cylinder 25 is shortened, driving the related parts to move in the opposite direction, and the clamping seat 29 is away from the parts to release the restriction.

[0022] like Figures 4 - 6 As shown, specifically, a sliding unit is installed on the base 12 near both ends, and the sliding unit is fixedly installed on the first seat body 35 and the second seat body 36 near both ends of the base 12, and is fixed on the base 12 as a basic supporting structure of the sliding unit. Two groups of sliding rods 37 are connected between the first seat body 35 and the second seat body 36, and a sliding seat 39 is slidably installed on the sliding rod 37, providing a movable track for the collection box 38, and one end of the collection box 38 is connected to the two groups of sliding seats 39; When the position of the collecting box 38 needs to be adjusted, the collecting box 38 can slide along the track formed by the first seat body 35 , the second seat body 36 and the sliding seat 39 , so that the collecting box 38 can extend out of the clamp platform 31 or retract into the clamp platform 31 .

[0023] like Figures 1 - 2 and Figures 4 - 6As shown in the figure, specifically, the driving part includes a first gear 310 fixedly installed at one end of the rotating shaft 33. A first housing 312 is fixedly installed on the side of a set of mounting seats 32 close to the first gear 310. The first housing 312 is adapted to cover the first gear 310. A first rack 313 slides through the first housing 312. The first rack 313 meshes with the first gear 310, and one end of the first rack 313 is connected to the top end of the inner wall of the first housing 312 by a spring. A bottom shell 315 is fixedly installed on the side of the bottom platform 12. A third seat body 316 is fixedly installed on the bottom shell 315. A connecting shaft 317 is installed on the third seat body 316 by bearings. Second gears 318 and third gears 319 are fixedly installed at both ends of the connecting shaft 317 respectively. The second gear 318 meshes with the first rack 313. At the same time, a second rack 320 is fixedly installed on the side of the collection box 38. The third gear 319 meshes with the second rack 320. When the driving part works, the rotating shaft 33 rotates to drive the first gear 310 to rotate. The first gear 310 drives the first rack 313 meshing with it to move linearly in the first housing 312, and the spring expands and contracts accordingly. The movement of the first rack 313 also causes the second gear 318 meshing with it to rotate, driving the connecting shaft 317 to rotate. The third gears 319 at both ends of the connecting shaft 317 rotate synchronously. The third gear 319 meshes with the second rack 320 on the side of the collection box 38, driving the collection box 38 to move along the track, realizing its extending or retracting action on the fixture platform 31. At the same time, a second housing 314 is fixedly installed on the bottom shell 315. The second housing 314 is used to cover and protect the gears. At the same time, one end of the first rack 313 passes through the second housing 314 and the bottom shell 315 in sequence.

[0024] It should be noted that when the processing of automotive parts is completed, when the rotating shaft 33 of the driving part rotates clockwise to work, it can synchronously drive the fixture platform 31 to tilt. The fixture platform 31 tilts towards the collection box 38. At the same time, the number of tooth blocks of the first rack 313 passing over the first gear 310 can make the first gear 310 rotate 45 degrees. Such as Figure 6As shown, specifically, a turntable 311 is fixedly installed at one end of the rotating shaft 33. The turntable 311 is adapted to apply torque to the rotating shaft 33. When it is necessary to drive the collection box 38 to move out or retract into the fixture platform 31, torque is applied to the turntable 311. The turntable 311 generates a rotational motion under the action of the torque. Since the turntable 311 is fixedly connected to one end of the rotating shaft 33, this torque will be transmitted to the rotating shaft 33, driving the rotating shaft 33 to rotate synchronously. The rotation of the rotating shaft 33 further drives the first gear 310 fixed thereon to rotate, triggering the transmission of the driving part gear and rack, causing components such as the first rack 313, the second gear 318, and the third gear 319 to act in sequence, and finally realizing the movement of the collection box 38 along the established track through the engagement with the second rack 320 on the side of the collection box 38.

[0025] As Figure 2 shown, specifically, a placement table 11 is fixedly installed on the fixture platform 31. An anti-slip pad is provided on the placement table 11. The placement table 11 is adapted to place automotive parts. By means of the anti-slip pad, the friction with the surface of the parts is increased, effectively preventing the parts from sliding during the placement process and ensuring that the parts can be accurately positioned at the preset position.

[0026] As Figure 2 shown, specifically, in this application, one end of the rotating shaft 33 can be connected to a driving member (a forward and reverse motor) as a power source. The forward and reverse motor can drive the rotating shaft 33 to rotate clockwise or counterclockwise through speed and steering control. When the processing of automotive parts is completed, the forward and reverse motor is started. The rotating shaft 33 rotates under the driving force of the motor, driving the fixture platform 31 to perform an automatic tilting action through the connecting frame 34, making it tilt towards the direction of the collection box 38. At the same time, the rotation of the rotating shaft 33 synchronously triggers the driving part gear-rack transmission mechanism, converting the rotational motion into a linear motion, and pushing the collection box 38 to automatically extend to a specified position below the fixture platform 31 along the preset track. During this process, the waste residues on the fixture platform 31 automatically slide down due to the tilting angle and fall into the collection box 38, thereby realizing the automatic collection of waste. The whole process does not require manual intervention, improving the efficiency and automation degree of waste cleaning after processing.

[0027] Working principle: When using the quick installation fixture for machining automotive parts on a milling machine, first place the automotive part on the placement table 11 of the fixture platform 31. The anti-slip pads on the placement table 11 prevent the part from sliding by means of friction, completing the preliminary positioning. Subsequently, start the four groups of first cylinders 21 of the clamping unit. The output ends of the first cylinders 21 drive the clamping plates 22 to move towards each other, clamping the four sides of the part. The anti-slip pads made of silica gel further enhance the clamping stability and resist the milling external force. At the same time, start the second cylinder 25 of the limiting unit. Its telescopic end drives the connecting rod 27 to move. Through the linkage of the connecting rod 28 and the hinge seat 26, the pressing seat 29 is pressed down to further fix the four corners of the part, preventing it from bouncing up and down and displacing, and double-guaranteeing the stability of the part during the machining process.

[0028] After the machining of the part is completed, apply torque to the turntable 311. The turntable 311 drives the rotating shaft 33 to rotate. On the one hand, the rotation of the rotating shaft 33 drives the first gear 310 to rotate. Through the transmission of the gear and the rack, the first rack 313, the second gear 318, and the third gear 319 act in sequence, and finally push the collection box 38 to extend along the track to the lower part of the fixture platform 31; On the other hand, the rotation of the rotating shaft 33 drives the fixture platform 31 to rotate clockwise around the axis through the connecting frame 34, making it tilt towards the collection box 38. The waste chips generated during the machining slide down into the collection box 38 along the trend, completing the automatic cleaning. After the cleaning is completed, rotate the turntable 311 in the reverse direction, the collection box 38 retracts, and the fixture platform 31 returns to the horizontal position, and then the next round of installation and machining of the parts can be quickly carried out to achieve cyclic operation.

Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention.
