One end of the feeding track is connected to the vibrating plate, and the feeding sensor is arranged at the end position of the other end of the feeding track to achieve the effect of automatic shutdown when there is no material.

[0006] The tail processing mechanism at least comprises a material unloading sensor, a material unloading cylinder, a material moving cylinder, a transverse material clamping cylinder and a longitudinal processing cylinder.

[0007] The longitudinal processing cylinder is provided with a fixture for reaming inner holes and punching pin holes at the output end, the material transfer cylinder is perpendicular to the movement direction of the sliding track, and the movement between the material transfer cylinder and the material discharging cylinder is in a cross direction.

[0009] Beneficial effects of the utility model: the double-opening lock drilling processing device provided by the utility model adopts a multi-cylinder pushing structure to realize the automatic transfer and positioning of material workpieces, optimize the process layout, be more integrated, perform front and rear drilling and deburring processing on the material workpieces, and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, a double-opening lock drilling processing device includes a feeding mechanism 1 for inputting workpieces for processing, a clamping mechanism 2 for conveying workpieces to a designated position, a front hole processing motor mechanism 3 for drilling a hole at one end of the workpiece, a rear hole motor mechanism 4 at a position relative to the front hole processing mechanism 3, and a tail processing mechanism 5 for reaming burrs and punching pin holes in the workpiece. The feeding mechanism 1 feeds the material into the track, and transfers the workpiece to a fixed processing station through the feeding mechanism 2, that is, the drilling processing relative to the front and rear rows, and finally transfers to the reaming inner hole and punching pin hole stations, and unloads the material after the processing is completed. The Y-axis and Z-axis all use servo motor displacement drilling to ensure the accuracy of the product.

[0012] The feeding mechanism 2 includes a bottom guide rail 6, a sliding rail 7 and a push cylinder 8. The sliding rail 7 is movably mounted on the bottom guide rail 6, and the sliding rail 7 is linearly reciprocated by the push cylinder 8. The bottom guide rail 6 serves as a support and a certain guide. The bottom guide rail 6 and the sliding rail 7 slide relative to each other linearly. The two can be concave-convex matched to achieve a limited sliding effect, but are by no means limited to this. The push cylinder 8 can be directly connected to the sliding rail 7 to push and pull back.

[0013] The sliding rail 7 is provided with a number of perforations 9 corresponding to the number and position of the stations. The front hole processing mechanism 3 and the rear hole processing mechanism 4 are staggered and arranged on opposite sides of the sliding rail 7. The front hole processing mechanism 3 and the rear hole processing mechanism 4 at least include a feeding cylinder 10 and a feeding seat 9 that are assembled in linkage. The feeding seat 11 enters and exits the perforation through the feeding cylinder 22. The feeding seats 11 and 9 are each provided with a positioning clamp for mounting the workpiece. The perforation 9 is provided with three entry and exit holes, corresponding to the three stations of front hole processing, rear hole processing and reaming burr processing. When in use, as the sliding guide rail 7 moves, each perforation 9 is tightened. For example, the perforation 9 corresponding to the front hole processing is first at the feeding mechanism 1. When the material workpiece reaches the specified position, the sliding rail 7 brings it to the front hole processing station. Here, the front hole processing mechanism 3 and the rear hole processing mechanism 4 are staggered and arranged at the drilling positions of the corresponding lock shells on both sides, and the material workpiece is directly brought to the feed seat 11 by the sliding track 7, and the feed seat 11 then transfers the material workpiece to the bottom of the drilling drill bit. As for the drilling drill bit and its main components, they are mature technical means, and no excessive elaboration and limitation are made here.

[0014] The feeding mechanism 1 includes a vibration plate 12, a feeding track 13 and a feeding sensor 14. One end of the feeding track 13 is connected to the vibration plate 12, and the feeding sensor 14 is arranged at the end position of the other end of the feeding guide rail 13. The vibration plate 12 drives the material workpiece to move to the track 13 through vibration. This is a mature technical means. This method is conducive to slow and gradual feeding. When the feeding sensor 14 detects that the material workpiece is in place, it controls the corresponding cylinder to move. Sensors such as the feeding sensor 14 can be proximity switches, but are by no means limited to this.

[0015] The tail processing mechanism 5 at least includes a material unloading sensor 15, a material unloading cylinder 16, a material transfer cylinder 17, a transverse material clamping cylinder 18 and a longitudinal processing cylinder 19. The longitudinal processing cylinder 19 is provided with a reaming fixture at the output end, and the material transfer cylinder 17 and the sliding track 7 move in a cross-shaped direction, and the moving directions of the material transfer cylinder 17 and the material unloading cylinder 16 are opposite. It also includes a work platform for placing each mechanism, and the work platform is provided with a material unloading port 21 corresponding to the end of the output stroke of the material unloading cylinder 16. When the feeding mechanism 7 transports the material to the end, that is, close to the reaming processing position, the material transfer cylinder 17 first pushes the material out, and the transverse material clamping cylinder 18 clamps the workpiece. The longitudinal processing cylinder 19 starts to work. It should be noted that the transverse material clamping cylinder 18 can be used in conjunction with a fixture, or in other ways, and there is no excessive restriction here. Then, the material unloading cylinder 16 and the longitudinal processing cylinder 19 cooperate and adjust to ream the inner hole burrs and punch the pin holes. When all the cylinders have returned, the unloading cylinder 16 is pushed out to push the workpiece to the unloading port 21, thereby realizing the fully automatic processing of the drilling series.

Therefore, they cannot be understood as limitations on the present invention.
