[0002] In basic engineering construction, the end plate of a pipe pile is a key component connecting the pipe piles. Currently, drilling holes on the side of large end plates still mainly relies on manual single-machine operation. Employees first mark the large end plates with pitch circles according to customer requirements, then stand the end plates upright, clamp them, and drill holes one by one using a vertical drill or hand drill. After that, each hole is tapped individually. Once the inspection is passed, the clamps are released, and the end plates are stacked flat. However, with the increase in production scale and output, the shortcomings of this traditional method have become increasingly apparent.

[0003] Manual operation in the processing of large end plates poses significant safety hazards, is labor-intensive, and has low production efficiency. Employees need to punch and tap holes on each end plate individually, consuming considerable time and energy, which cannot meet the high efficiency requirements of modern production. Traditional manual operation not only increases production costs but also makes it difficult to guarantee product consistency, resulting in a high defect rate. Therefore, there is an urgent need for a new type of large end plate side drilling device to solve the problems of existing technology, improve production efficiency, reduce operational risks, and thus promote the healthy development of the industry.

[0032] This utility model provides a device for drilling holes on the side of a large end plate. Please refer to [link / reference]. Figures 1-4 The system includes a workbench 1; the workbench 1 includes a support frame 101 and a control console 102 disposed on one side of the support frame 101; a processing mechanism 2, disposed on one side of the control console 102, which includes two hole processing devices 201 and a drive component 202 disposed on one side of the hole processing devices 201, the included angle between the two hole processing devices being adjustable; and a clamping mechanism 3, disposed above the support frame 101 and on one side of the drive component 202, which includes a chassis 301, an indexing turntable 302 disposed above the chassis 301, a steering gear 303 disposed below the chassis 301, a locking component 304 disposed on one side of the steering gear 303, a drive motor 305 disposed below the steering gear 303, a pressure block 306 for fixing the end plate, and a clamping bolt 307 for locking the pressure block.

[0033] The chassis 301 includes a receiving cavity 301a; the indexing turntable (302) includes a clamping groove 302a disposed on its surface, a plurality of positioning holes 302b disposed in the clamping groove 302a, and a limiting block 302c disposed between the positioning holes 302 for fixing the end plate; the clamping groove 302a is composed of a circular groove and three evenly distributed straight grooves, and the included angle between adjacent straight grooves is 120 degrees;

[0034] The steering gear 303 includes a gear hub 303a disposed above it, the gear hub 303a passing through the indexing turntable 302, and the gear hub 303a and the indexing turntable 302 are fixed by a convex key 303a-1, the indexing turntable 302 rotates with the steering gear 303; the gear hub 303a has a threaded groove 303a-2, the threaded groove 303a-2 cooperating with the clamping bolt 307; the locking member 304 includes a locking insert 304a and a telescopic cylinder 304b disposed on one side of the locking insert 304a; the locking insert 304a cooperates with the tooth groove of the steering gear 303; the pressure block 306 has a semi-circular slot in the middle, the semi-circular slot can surround the clamping bolt 307; the control console 102 is electrically connected to the driving member 202, the driving motor 305 and the telescopic cylinder 304b.

[0035] It should be noted that the workbench 1 is the basic structure of this device, mainly composed of a load-bearing frame 101 and a control console 102. The load-bearing frame 101 is responsible for supporting the weight of the entire device, while the control console 102 provides a control interface for the operator. The drive unit 202 is a reciprocating stepper motor that can reciprocate to drive the drilling bit, providing power to drive the hole processing equipment 201. The hole processing equipment 201 is a device for drilling holes on the side of the end plate, performing the actual drilling operation, specifically a drilling machine and a tapping machine. The relative angle between the drilling machine and the tapping machine is adjustable to accommodate different models of end plates. For example, some end plates have 6 holes, while others have 8 holes, and the included angle between two adjacent holes is different. Therefore, by adjusting the positions of the drilling machine and the tapping machine, the two hole positions are ensured to be aligned, so that one can drill while the other can tap simultaneously.

[0036] Preferably, the function of the receiving cavity 301a is to collect coolant and prevent the cutting fluid sprayed during drilling from overflowing and damaging the working environment.

[0037] Preferably, the indexing turntable 302 is located within the chassis 301. The surface of the indexing turntable 302 is provided with a clamping groove 302a. The width of the clamping groove 302a is the same as the width of the limiting block 302c. The limiting block 302c can slide on the groove to accommodate circular end plates of different diameters. The limiting block 302c is locked by inserting a positioning pin or bolt into the positioning hole 302b to lock the position of the limiting block 302c, thereby clamping the limiting block 302c. The length of the limiting block 302c is twice the spacing between the positioning holes 302b. Five linearly evenly distributed positioning holes 302b are provided in a single straight groove. The indexing turntable 302 can accurately position the end plate and provide stable support for drilling.

[0038] Preferably, the steering gear 303 is fixedly connected to a gear hub 303a, which passes through the indexing turntable 302 and extends a distance from above. A keyway is provided in the part of the indexing turntable 302 that contacts the gear hub 303a. The gear hub 303a is fixed to the indexing turntable 302 by a protruding key 303a-1, so that the indexing turntable 302 rotates with the steering gear 303. The clamping bolt 307 is threaded in the threaded groove 303a-2 to lock the pressure block 306, further enhancing the stability of the end plate.

[0039] Preferably, the end plate is fixed as follows: the limiting block 302c is fixed in the clamp slide groove 302a according to the end plate specifications, the end plate is placed on the limiting block 302c, the pressure block 306 is used to span the end plate and is fitted onto the clamping bolt 307, and the clamping bolt 307 is tightened with a fastening tool so that the clamping bolt 307 is deeply inserted into the threaded groove 303a-2, and the end plate is fixed.

[0040] Preferably, the hole-making equipment 201, drive motor 305, and telescopic cylinder 304b are controlled and coordinated by the PLC control system through the console 102. This device can automatically complete each drilling process, specifically: the steering gear 303 rotates to a fixed angle X - the telescopic cylinder 304b extends the locking block 304a to lock the gear - the drive unit 202 starts to push the hole-making equipment 201 to drill the side of the end plate - the drive unit 202 retracts - the telescopic cylinder 304b retracts to release the gear lock - the steering gear 303 rotates to a fixed angle X..., continuously cycling 360 / X times, and the drilling ends.

[0041] In summary, the large end plate side drilling device of this utility model uses a drive motor to drive a steering gear, which in turn rotates the indexing turntable to adjust the drilling position. The processing mechanism drills the end plate side sequentially in steps. During drilling, a locking component locks the gear to prevent the drilling position from shifting. It has a high degree of automation, precise drilling position, and significantly improved production efficiency. In addition, the indexing turntable in the clamping mechanism has multiple positioning holes. Combined with the design of limit blocks and pressure blocks, it can flexibly fix end plates of different specifications, adapt to the drilling needs of various workpieces, and can quickly and accurately position the workpiece, further ensuring the accuracy of each drilling.
