[0002] At present, most mechanical parts are processed before production for the convenience of assembly. The edges of the parts are milled, chamfered or drilled so that the parts can be assembled quickly and accurately in the subsequent assembly process.

[0003] However, most existing drilling and milling equipment can only perform single milling or drilling processing on parts. Both cannot be completed simultaneously in the same equipment. In addition, during processing, parts need to be manually grasped for drilling and milling, which is very unsafe. In addition, manual processing methods can easily lead to production efficiency not keeping up, and the precision of the processed parts is not accurate enough.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Invention

The limiting component is movably placed in the loading platform and is located directly below the clamping hand. A reset spring for lifting the limiting component is provided below the limiting component. When the clamping hand picks up the material, it is used to press down the limiting component to expose the arc-shaped part for picking up; when the clamping hand clamps the arc-shaped part upward, the reset spring pushes the limiting component upward to restore it to its original state.

[0015] As a preferred embodiment, the machine is provided with a processing clamping block that can slide up and down, and the processing clamping block is used to clamp arc-shaped parts for processing.

[0031] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0032] like Figure 1-7 As shown, an automatic finishing, drilling and flattening equipment for arc-shaped parts includes a machine platform 100, on which a clamping mechanism 110, a straightening mechanism 120 and a drilling and milling mechanism 130 are provided; the clamping mechanism 110 is set directly above the machine platform 100, and the clamping mechanism 110 has a clamping hand 111 for clamping the arc-shaped parts, and an arc-shaped clamping groove 112 adapted to the arc-shaped parts is provided on the clamping hand 111, so that the clamping hand 111 can accurately clamp the arc-shaped parts to avoid falling during movement.

[0033] Specifically, the straightening mechanism 120 is arranged at the side end of the machine table 100, and the straightening mechanism 120 has a rotatable straightening rod 121. By providing a boss protruding outward on the straightening rod 121, the straightening rod 121 can pass through the arc part and rotate, and then the arc part is driven to rotate together by the straightening rod 121, thereby realizing the angle adjustment of the arc part, which is convenient for the subsequent drilling and milling mechanism 130 to perform drilling and milling processing on both ends of the straightened arc part at the same time.

[0034] In this embodiment, the clamping mechanism 110 further includes a fixed base 113 for fixing on the side wall of the machine 100, a first transverse seat 114, a first lifting seat 115 and a clamping cylinder 116 for controlling the tightness of the clamping hand 111; further, by providing a first transverse slide rail 1141 laterally installed on the fixed base 113 between the first transverse seat 114 and the fixed base 113, the first transverse seat 114 is installed on the first transverse slide rail 1141, and the first transverse seat 114 is made to slide left and right along the extension direction of the first transverse slide rail 1141, and further by providing a vertical setting on the first transverse seat 114 The first vertical slide rail 1151 is then installed on the first vertical slide rail 1151, and the first lift seat 115 is enabled to slide up and down along the first vertical slide rail 1151, and a first front-rear slide rail 1152 is provided on the lower end surface of the first lift seat 115 along the front-rear direction. The clamping hand 111 is installed on the first front-rear slide rail 1152, and the clamping hand 111 is enabled to slide along the extension direction of the first front-rear slide rail 1152. The clamping cylinder 116 is also provided above the clamping hand 111 to control the clamping closing state of the clamping hand 111 so that it can clamp and move the arc-shaped parts.

[0035] In actual use, a first control cylinder 117 is provided at the side end of the fixed base 113 for controlling the first transverse seat 114 to slide along the first transverse slide rail 1141, and a second control cylinder 118 is provided on the first transverse seat 114 for controlling the first lifting seat 115 to slide up and down along the first vertical slide rail 1151. A third control cylinder 119 is also provided at the lower end of the first lifting seat 115 for controlling the clamping hand 111 to move forward and backward along the first front and rear slide rails 1152. By using the three control cylinders in coordination, the clamping position of the clamping hand 111 can be continuously adjusted to achieve more precise clamping of arc-shaped parts.

[0036] In this embodiment, a loading mechanism 140 for loading arc-shaped parts for processing is also included, and the loading mechanism 140 includes a feeding rack 141 and a loading platform 142. A feeding channel 1411 is provided in the feeding rack 141 for placing arc-shaped parts therein and arranged along the axial direction of the feeding rack 141, and a discharge port 143 is provided at the side end of the feeding rack 141 for discharging arc-shaped parts. The loading platform 142 is arranged at the discharge port of the feeding rack 141. On one side of the outlet 143, a pushing module 144 is provided on the other side of the feeding rack 141 for pushing the arc-shaped parts in the outlet 143 to the loading platform 142. The pushing module 144 on the other side pushes the arc-shaped parts through the pushing cylinder, so that the pushing module 144 passes through the outlet 143 of the feeding rack 141 and pushes the internal arc-shaped parts to the loading platform 142, and then the clamping hand 111 is used to pick up the arc-shaped parts at the outlet 143.

[0037] Specifically, a limiting component 1421 for limiting the forward movement of the arc-shaped part is provided at the front end of the loading platform 142. The limiting component 1421 is movably placed in the loading platform 142 and is located directly below the clamping hand 111. A return spring 1422 for lifting the limiting component 1421 is provided below the limiting component 1421. When the clamping hand 111 picks up the material, it is used to press down the limiting component 1421 to expose the arc-shaped part, and then pick it up and move it; when the clamping hand 111 clamps the arc-shaped part upward, the return spring 1422 will push the limiting component 1421 upward to restore it to its original state, so that the next arc-shaped part can enter.

[0038] In this embodiment, a processing clamping block 150 that can slide up and down is provided on the rear side wall of the machine table 100. The processing clamping block 150 is used to clamp arc-shaped parts for processing. A lifting motor 151 is provided at the top of the machine table 100 to control the lifting movement of the processing clamping block 150. A transverse through-groove 152 is also provided at the side end of the processing clamping block 150. The through-groove 152 is used to accommodate arc-shaped parts, so that after the processing clamping block 150 clamps the arc-shaped part, the straightening rod 121 of the straightening mechanism 120 passes through the through-groove 152, and the straightening rod 121 drives the arc-shaped part in the through-groove 152 to rotate, thereby realizing rapid adjustment of the processing angle, facilitating subsequent drilling and milling processing, and reducing cumbersome rotation processes.

[0039] In this embodiment, the drilling and milling mechanism 130 used includes a milling cutter assembly 131 for milling processing and a drill bit assembly 132 for drilling. The milling cutter assembly 131 is arranged above the drill bit assembly 132, so that when the processing clamping block 150 moves to the drilling and milling mechanism 130, the milling cutter assembly 131 and the drill bit assembly 132 are started at the same time to perform milling and drilling actions on the two ends of the arc part respectively, thereby completing the automatic processing of the arc part without manual grasping, improving production efficiency, and ensuring the processing precision requirements.

[0040] Specifically, the drilling and milling mechanism 130 has a translation module 133 for controlling the milling cutter assembly 131 and the drill bit assembly 132 to move back and forth simultaneously, so that the two move synchronously to achieve the effect of simultaneous milling and drilling.

[0041] In this embodiment, a spray assembly is also included. By arranging the spray assembly on one side of the drilling and milling mechanism 130, it is used to spray cooling coolant on the arc-shaped parts being processed. The cooling coolant can effectively cool, cool and lubricate the arc-shaped parts being processed, thereby improving the qualified quality of the product.

[0042] In this embodiment, a collection box is also provided on the machine 100. A partition with a leakage hole is provided in the collection box, which can be used to store the processed arc parts. The cooling liquid flowing down together then flows out from the leakage hole, leaving the processed arc parts, which are then uniformly packaged.

[0043] In actual use, the milling cutter assembly 131 has a milling cutter, and the drill bit assembly 132 has a drill bit. The milling cutter is detachably arranged in the milling cutter assembly 131, and the drill bit is also detachably installed in the drill bit assembly 132. By quickly disassembling and replacing drill bits of different sizes, different drilling processes can be performed on arc-shaped parts to meet the usage needs of different customers.

[0044] Specifically, a trimming mechanism 160 for trimming the end faces of arc-shaped parts is provided on one side of the drilling and milling mechanism 130. The trimming mechanism 160 has an end milling cutter, which can trim the end faces of the drilled and milled arc-shaped parts and further level the end faces of the arc-shaped parts to avoid burrs on the edges of the arc-shaped parts and to prevent the surfaces of other arc-shaped parts from being scratched during collection.

[0045] The working principle of this equipment is as follows: first, the arc-shaped parts to be processed are placed in the loading mechanism 140, and then are pushed to the loading platform 142 in sequence. Then, the clamping hand 111 clamps and removes the arc-shaped parts in the limiting component 1421 of the loading platform 142, and the clamping hand 111 is provided with an arc-shaped clamping groove 112 adapted to the arc-shaped parts to prevent the clamping hand 111 from loosening and falling off when transferring the arc-shaped parts. The arc-shaped parts are transferred and placed on the processing clamping block 150 by the clamping hand 111. At this time, the arc-shaped parts are placed on the processing clamping block 150. The straightening mechanism 120 at the side end extends the straightening rod 121 into the processing clamping block 150 to drive the arc part to rotate, so that the processing angle of the arc part is correctly placed, and then the arc part is moved to the milling cutter assembly 131 or the drill assembly 132 for processing through the processing clamping block 150 that can slide up and down, and the two ends of the arc part are machined in turn; when the processing is completed, the processing clamping block 150 is released, so that the processed arc part falls into the collection box below for unified collection and packaging.

[0046] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
