Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and in particular to a positioning tooling for drilling gear shafts. Background Technology

[0002] In mechanical manufacturing, the machining accuracy and efficiency of gear shafts are crucial to product performance and production cycle. End face drilling is a key process, but existing positioning structures have obvious drawbacks.

[0003] Commonly used positioning structures, such as positioning rods, pressure rods, and nut combinations, have a decent positioning effect, but the nuts and pressure rods need to be disassembled and reassembled before and after processing to pick up and put down the gear shaft. Disassembly and reassembly are time-consuming, and the screwing of the nuts is prone to jamming due to thread fit issues, which greatly extends the assembly time and results in low production efficiency.

[0004] When switching end face processing, the existing structure lacks a convenient conversion mechanism, requiring disassembly, adjustment and reassembly, which is complicated and prone to introducing positioning errors. It is time-consuming and affects accuracy, making it difficult to meet the needs of modern production for high efficiency and flexibility, restricting efficiency improvement and increasing costs.

[0005] Therefore, it is essential to provide a positioning fixture for drilling gear shafts to address the shortcomings of existing technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning fixture for drilling gear shafts, which avoids the shortcomings of the prior art. This utility model overcomes the defects of the prior art in gear shaft drilling positioning fixtures, such as low efficiency, inconvenient switching of processing, and easy impact on positioning accuracy. It provides a positioning fixture for drilling gear shafts, which achieves rapid positioning of gear shafts, multi-position processing switching, and efficient picking and placing by optimizing the positioning structure design, thereby improving processing accuracy and production efficiency.

[0007] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0011] Preferably, the drilling workbench includes a workbench body, which is fixedly installed on the drilling machine body. A sliding groove is provided on the upper end face of the workbench body, and two sliding support plates are slidably engaged on the sliding groove.

[0020] The present invention will be further described in conjunction with the following embodiments.

[0021] Example 1. like Figure 1-3 As shown, a positioning fixture for drilling gear shafts includes a drilling machine body 1, a drilling worktable mounted on the drilling machine body 1, a conversion and adjustment positioning mechanism 2 mounted on the drilling worktable, and several gear shaft bodies 3 movably engaged on the conversion and adjustment positioning mechanism 2.

[0022] like Figure 1-3 As shown, the conversion adjustment positioning includes two sliding support plates 4, which are slidably engaged on the rotating worktable. A motor A 5 is mounted on each sliding support plate 4, and a rotating disk 6 is mounted on the output shaft of the motor A 5. A linear slide rail 7 is mounted radially on the outer end face of each rotating disk 6. A support plate A 8 is fixedly mounted on the outer side of the two linear slide rails 7, and a support plate B 9 is slidably mounted between the two linear slide rails 7.

[0023] like Figure 1-3 As shown, electric push rods 10 are installed between the corners of support plate A8 and support plate B9 respectively. Several rectangular through holes 11 are equally spaced on support plate A8 and support plate B9 respectively. An adjustment clamping assembly 12 is installed at each rectangular through hole 11. A gear shaft body 3 is clamped between two corresponding adjustment clamping assemblies 12 on support plate A8 and support plate B9. The end of the gear shaft body 3 is movably abutted against the processing end of the drilling machine body 1.

[0024] like Figure 1-3 As shown, the drilling workbench includes a workbench body 13, which is fixedly installed on the drilling machine body 1. A sliding groove 14 is provided on the upper end face of the workbench body 13. Two sliding support plates 4 are slidably engaged on the sliding groove 14. An electric telescopic rod 15 is installed between each sliding support plate 4 and one end of the sliding groove 14.

[0025] like Figure 1-3 As shown, the adjusting clamping assembly 12 includes a motor B 16, which is installed on the support plate A 8 and the support plate B 9 near the rectangular through hole 11. A bidirectional ball screw 17 is installed on the output shaft of the motor B 16, and the two ends of each bidirectional ball screw 17 are movably installed with the inner wall of the rectangular through hole 11 through bearings.

[0026] like Figure 1-3 As shown, each bidirectional ball screw 17 is equipped with two screw nuts 18, each screw nut 18 is equipped with an arc-shaped support plate 19, and each arc-shaped support plate 19 is symmetrically equipped with two triangular snap-fit ​​blocks 20 on its arc surface. Four triangular snap-fit ​​blocks 20 are symmetrically snapped onto the outer side of one end of the gear shaft body 3.

[0027] Start the electric push rod 10. The electric push rod 10 extends and retracts to drive the support plate B 9 to slide along the linear slide rail 7. Adjust the distance between the support plate A 8 and the support plate B 9 according to the length of the gear shaft body 3 to be processed. Then turn off the electric push rod 10.

[0028] Place the two ends of the three gear shaft bodies 3 into the rectangular through holes 11 of the support plates A 8 and B 9 respectively. Start the motor B 16. The motor B 16 drives the bidirectional ball screw 17 to rotate. The screw nut 18 drives the arc-shaped support plates 19 to move closer to each other until the triangular locking block 20 is locked on the outside of the end of the gear shaft body 3. At this time, the gear shaft body 3 is firmly clamped. Turn off the motor B 16.

[0029] If it is necessary to convert and drill holes on the two end faces of the gear shaft body 3, first start the motor A5. The motor A5 drives the rotating disk 6 to rotate. The rotating disk 6 drives the support plate A8, support plate B9 and gear shaft body 3 to rotate synchronously through the linear slide rail 7. When the target angle is reached, turn off the motor A5.

[0030] If it is necessary to move the gear shaft body 3 at the three workstations to the processing end of the drilling machine body 1 for processing in sequence, first start the electric telescopic rod 15. The electric telescopic rod 15 drives the sliding support plate 4 to slide along the sliding groove 14, so that the end of each gear shaft body 3 to be processed is matched with the processing end of the drilling machine body 1. This facilitates drilling the gear shaft body 3 at a single workstation while loading and unloading gear shaft bodies 3 at other workstations, thus improving work efficiency.

[0031] Start the drilling machine body 1 to drill the end face of the gear shaft body 3. After the drilling is completed, start the motor B 16 to rotate in the opposite direction. The bidirectional ball screw 17 drives the screw nut 18 and the arc support plate 19 to move away from each other. The triangular locking block 20 disengages from the slot of the gear shaft body 3, and the processed gear shaft body 3 can be quickly removed.

[0032] This utility model includes a drilling machine body 1, a drilling worktable mounted on the drilling machine body 1, a conversion adjustment and positioning mechanism 2 mounted on the drilling worktable, and several gear shaft bodies 3 movably clamped on the conversion adjustment and positioning mechanism 2. The conversion adjustment and positioning mechanism 2 enables multi-position processing switching of the gear shafts without repeated disassembly and assembly, avoiding positioning errors. The gear shafts can be quickly clamped and picked up by adjusting the clamping component 12, shortening auxiliary time. The overall structure is reasonably designed and easy to operate, effectively improving the accuracy and efficiency of gear shaft drilling. It is suitable for the processing and production of large batches of gear shafts of various specifications.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
