[0048] Referring to Figures 7-11 The feeding mechanism 20 is described in detail.

[0049] The feeding mechanism 20 comprises a telescopic power piece 201, a bracket for fixing and supporting the telescopic power piece 201, a first feeding block 202 connected with the telescopic end 2011 of the telescopic power piece 201, and a second feeding block 203. In this embodiment, the telescopic power piece 201 is described as a telescopic cylinder.

[0050] Specifically, the telescopic power unit 201 comprises a telescopic end 2011 and a main body, the telescopic end 2011 is sleeved with a connecting block 2012 in a "convex" shape structure, and a first feeding block 202 and a second feeding block 203 are connected with the telescopic end 2011 through the connecting block 2012. The first feeding block 202 is provided with a limiting groove 2023 matched with the connecting block 2012, and the second feeding block 203 is provided with a stroke groove 2032 matched with the connecting block 2012, the connecting block 2012 is arranged at one end of the stroke groove 2032, and the other end is clamped with a spring sleeve 2033.

[0051] The spring sleeve 2033 is provided with a cavity and a push rod 20333 and a compression spring 20336 arranged in the cavity, the cavity comprises a first cavity 20331 and a second cavity 20332, both cavities are communicated with the side wall of the spring sleeve 2033, and both cavities are arranged in a same straight line and connected in a head-to-tail manner.

[0052] The diameter of the first cavity 20331 is smaller than that of the second cavity 20332, the push rod 20333 is composed of a head part 20335 and a rod part 20334, the head part 20335 is arranged in the second cavity 20332, and the rod part 20334 is arranged in the first cavity 20331 and a part of the rod part 20334 extends out of the spring sleeve 2033 from the first cavity 20331.

[0053] Preferably, the stroke groove 2032 is provided with an idle stroke area H, and a clamping groove 2031 for accommodating a workpiece is arranged on the top of the second feeding block 203, and two clamping grooves 2022 and 2021 for accommodating workpieces are arranged on the top of the first feeding block 202, and the clamping groove 2031 on the second feeding block is arranged in alignment with the clamping groove 2021 on the first feeding block 202 away from the telescopic power unit 201.

[0054] A sensor for detecting whether the first feeding block 202 and the second feeding block 203 are homed is arranged on the telescopic power unit 201, and the first feeding block 202 and the second feeding block 203 can move forward and backward through the connecting block 2012.

[0055] Specifically, the side wall of the through slot 305 of the main machining block 30 is further provided with a limiting block 306, and two second slot bodies 302 are arranged on the main machining block 30, and the limiting block 306 is arranged between the two second slot bodies 302. When the telescopic power member 201 starts to act from the initial position, the telescopic power member 201 pushes the first feeding block 202 to move forward. It should be noted that the forward movement at this time specifically refers to the extension direction of the telescopic end 2011 of the telescopic power member. When the clamping groove 2022 on the side of the first feeding block 202 close to the telescopic power member 201 coincides with the clamping block on the second feeding block 203, that is, the connecting block 2012 runs through the empty stroke area H, the connecting block 2012 abuts against the push rod 20333 of the spring sleeve 2033 and extrudes and compresses the compression spring 20336 to shrink. When the connecting block 2012 abuts against the side wall of the stroke slot 2032, the telescopic power member 401201 pushes the first feeding block 202 and the second feeding block 203 to move forward. After the end of the second feeding block 203 abuts against the limiting block 306, the first feeding block 202 and the second feeding block 203 are in place.

[0056] The number of the third slot bodies 303 on the main machining block 30 is also two, and the two third slot bodies 303 are respectively arranged on the same straight line as the second slot bodies 302, that is, the third slot bodies 303 and the second slot bodies 302 are respectively arranged on the left and right sides of the through slot 305. The first feeding block 202 is arranged on the side close to the third slot body 303, and the limiting block 306 is arranged on the side close to the second slot body 302.

[0057] After the first feeding block 202 and the second feeding block 203 are pushed to the position by the telescopic power member 401201, that is, after the second feeding block 203 abuts against the limiting block 306, the clamping grooves 2031, 2022 and 2021 are respectively aligned with the third slot bodies 303 and the second slot bodies 302.

[0058] Further, the lower side of the first feeding block 202 and the second feeding block 203 is further provided with a wedge-shaped sliding block, and the lower part of the two sides of the first slot body 301 is provided with a sliding groove matched with the wedge-shaped sliding block. The through slot is arranged in the middle part of the first slot body 301.

[0059] Reference Figures 12-13 The pushing mechanism 40 will be described in detail.

[0060] The pushing mechanism 40 mainly includes a telescopic power member 401, a fixed plate 402 inserted and arranged with the telescopic power member 401, two plug blocks 403 inserted and arranged on the fixed plate 402, and a pushing block 404 movably arranged on the plug block 403. Further, it further includes an elastic compensation member 405 arranged between the plug block 403 and the pushing block 404. In this embodiment, the elastic compensation member 405 is a compression spring 20336, and the telescopic power member 401 is a telescopic cylinder.

[0061] The fixed plate 402 is rectangular structure, a circular socket is arranged in the middle of the back surface, used for being plugged with the end of the telescopic power member 401, and two insertion slots for connecting the insertion block are arranged on the front side of the fixed plate 402, and the socket is arranged between the two insertion slots.

[0062] Specifically, the insertion block 403 is also "convex" structure, that is, the extension part 4031 extending upward and downward is arranged on the front end of the insertion block 403, wherein the end of the insertion block 403 is provided with a circular hole for accommodating the elastic compensation member 405, and the elastic compensation member 405 is partially arranged in the circular hole, and the other end is in abutment with the pushing block 404.

[0063] The pushing block 404 is connected with the insertion block 403, and the end of the pushing block 404 is provided with the "convex" structure slot 4041, and the slot 4041 is connected with the insertion block 403, so that the pushing block 404 can move forward and backward on the insertion block 403. It should be noted that the forward movement at this time specifically refers to the extension direction of the telescopic end 2011 of the telescopic power member, that is, the direction indicated by the arrow in the drawing. After the insertion block 403 is connected with the slot 4041, the extension part 4031 is arranged to prevent the pushing block 404 from being separated from the insertion block 403 when moving forward.

[0064] The length of the insertion block 403 is greater than the depth of the slot 4041, when the workpiece is transported to the clamping groove 2031, 2022, 2021 on the first feeding block 202, the second feeding block 203 by the feeding unit, and the clamping groove 2031, 2022, 2021 is aligned with the second slot body 302, the third slot body 303 respectively, the pushing block 404 is driven by the telescopic power member 401 to move forward and push the workpiece into the third slot body 303 from the clamping groove 2031, 2022, 2021. The arrangement of the elastic compensation member 405 effectively prevents the position of the workpiece from deviating and causing cumulative error, that is, because the pushing block 404 is relatively hard, the workpiece is pushed forward, the position of the workpiece exceeds the original expected position, and the next time the workpiece enters, the position is further exceeded due to excessive external force.

[0065] The feeding unit 50 is composed of two rectangular blocks 502 arranged in the third slot body 303, a transition block 501 connected with the two rectangular blocks 502, and a telescopic cylinder, that is, the workpiece is pushed into the third slot body 303 by the pushing block 404 and abuts against the rectangular block 502 for processing, and after the processing is completed, the telescopic cylinder drives the rectangular block 502 to push the workpiece into the through slot 305 and then falls into the feeding chute 103.

[0066] It should be noted that a plurality of processing units can be arranged on a tapping machine, that is, Figures 1-4The two groups of processing units are mirror-symmetrical to each other. Each group of processing units is composed of a feeding channel 2034, a processing unit, a feeding mechanism 20, a discharging unit 50, a main processing block 30 and a discharging groove. When the large plate 102 and the support table 105 are large enough, the number of groups of processing units can continue to increase.

[0067] The above-described embodiments are merely preferred embodiments of the present application, and are not intended to limit the concept and scope of the present application. Various modifications and improvements to the technical solutions of the present application made by those skilled in the art without departing from the design concept of the present application shall fall within the protection scope of the present application. The technical content claimed by the present application has been fully recorded in the claims.
