Description

Technical Field

[0001] This utility model relates to the field of gear ring drilling fixtures, and in particular to a fixing fixture for drilling gear rings. Background Technology

[0002] In high-end equipment fields such as heavy machinery, wind power equipment, and marine propulsion, large gear rings, as core transmission components, play a crucial role in power transmission and torque bearing. Their machining quality directly determines the operational stability and service life of the equipment. The drilling process, as the core link in the machining of large gear rings, requires the machining of dozens or even hundreds of high-precision mounting holes on the end face of the gear ring, the inner ring flange, or the outer ring boss.

[0003] Currently, during the drilling process of large gear rings, the fixtures used require loosening the fastening bolts or nuts with tools before they can be moved to the target position when adjusting their position according to the size of the gear ring. This adjustment method is cumbersome and time-consuming, which seriously affects the processing efficiency. In addition, existing fixtures used for drilling large gear rings mostly rely on nuts for fastening. However, during drilling operations, nuts are easily loosened due to continuous vibration, causing the clamping force of the fixture on the gear ring to gradually weaken and the firmness to decrease. Ultimately, this has an adverse effect on the processing accuracy and finished product quality of the gear ring. Utility Model Content

[0004] This utility model relates to a fixing fixture for drilling gear rings, which solves the problem that current fixtures for drilling large gear rings require tools to loosen bolts or nuts when adjusting the position according to the size of the gear ring. This adjustment method is cumbersome, time-consuming, and inefficient. Furthermore, since the fixtures rely heavily on nuts for fastening, the nuts are prone to loosening due to continuous vibration during drilling. This leads to a gradual weakening of the clamping force of the fixture on the gear ring and a decrease in its firmness, ultimately affecting the processing accuracy and the quality of the finished product.

[0005] In a first aspect, this utility model provides a fixing fixture for drilling gear rings, specifically comprising: a fixture base, wherein the upper end face of the fixture base is provided with T-shaped grooves arranged in a circular array, and an I-shaped sliding seat is slidably connected inside the T-shaped grooves; limit insertion holes are uniformly provided inside the T-shaped grooves; a rectangular mounting opening is provided on the upper end face of the I-shaped sliding seat, and a H-shaped tube is fixedly connected inside the rectangular mounting opening; a spring guide rod is fixedly connected to each of the two rectangular sliding cavities on the H-shaped tube, and a pinching plate is slidably connected to each of the two rectangular sliding cavities on the H-shaped tube through the spring guide rod; and a limit insertion rod is fixedly connected to the lower end of each of the two pinching plates facing each other; a spring is sleeved on the outside of the spring guide rod; a fixture is provided on the upper part of the I-shaped sliding seat; and the upper end face of the fixture base holds the gear ring workpiece by means of the fixture.

[0006] Furthermore, the limiting rod passes through one side of the H-shaped tube and one side of the lower part of the I-shaped sliding seat; when the I-shaped sliding seat is in a limited position inside the T-shaped sliding groove, the limiting rod is inserted into the limiting hole.

[0007] Furthermore, the bottom surface of the fixture base has rectangular openings arranged in a ring array, and the rectangular openings communicate with the T-shaped slide grooves, and the width of the rectangular openings is equal to the width of the lower side inside the T-shaped slide grooves.

[0008] Furthermore, the clamp includes a clamping plate and a clamping screw. A sliding rod that passes through the I-shaped sliding seat is fixedly connected to the bottom end face of the clamping plate, and the sliding rod is slidably connected to the I-shaped sliding seat. The clamping screw is fixedly connected to the top end face of the I-shaped sliding seat, and the clamping screw passes through the clamping plate. A fixing nut is threadedly connected to the upper outer end of the clamping screw.

[0009] Furthermore, it also includes an anti-loosening component, which is disposed on the top of the clamping plate. The anti-loosening component includes a rectangular slide cylinder and a locking gear. The rectangular slide cylinder is fixedly connected to the top surface of the clamping plate, and a rectangular slider is slidably connected inside the rectangular slide cylinder. A locking block is fixedly connected to the head end face of the rectangular slider. The locking gear is fixedly connected to the bottom end face of the fixing nut. A spring is provided inside the rectangular slide cylinder at the tail end of the rectangular slider. A strip-shaped opening is provided on the upper end face of the rectangular slide cylinder. A limit slider is fixedly connected to the upper end face of the rectangular slider, and the limit slider is slidably connected to the strip-shaped opening on the upper end face of the rectangular slide cylinder. A rotating block is rotatably connected to the upper end face of the limit slider through a rotating shaft. An L-shaped limit block is fixedly connected to the top of the rectangular slide cylinder.

[0010] Furthermore, when the anti-loosening component is in the anti-loosening state, the locking block engages with the locking gear.

[0011] This utility model provides a fixing clamp for drilling gear rings, which has the following advantages:

[0012] 1. By cooperating with the I-shaped sliding seat, the H-shaped tube, the pinch plate, the limiting rod, the T-shaped slide, and the limiting hole, the position of the fixture can be adjusted according to the size of the gear ring workpiece. During the adjustment process, it is only necessary to manually move the two adjacent pinch plates in opposite directions at the same time to pull the limiting rod out of the limiting hole. Then, the I-shaped sliding seat can be slid and adjusted to adjust the position of the fixture. The entire adjustment process does not require the use of tools. This adjustment method is convenient and time-saving, and significantly improves the processing efficiency of the gear ring workpiece.

[0013] 2. By setting the anti-loosening component, after the gear ring workpiece is fixed, the locking block engages with the locking gear to effectively lock and limit the fixing nut. This prevents the fixing nut from loosening even in a continuous vibration environment, avoiding the weakening of the clamping force of the fixture on the gear ring workpiece due to the decrease in clamping force. This not only significantly enhances the firmness of clamping the gear ring workpiece, but also ensures the machining accuracy and finished product quality of the gear ring workpiece.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes a fixing fixture for drilling gear rings, comprising: a fixture base 1, which is mounted on a drilling machine tool; T-shaped grooves 101 are arranged in a ring array on the upper surface of the fixture base 1, and an I-shaped sliding seat 2 is slidably connected inside the T-shaped grooves 101; limit insertion holes 103 are uniformly arranged inside the T-shaped grooves 101; a rectangular mounting opening 201 is provided on the upper surface of the I-shaped sliding seat 2, and a H-shaped tube 202 is fixedly connected inside the rectangular mounting opening 201; spring guide rods 205 are fixedly connected to the two rectangular sliding cavities on the H-shaped tube 202, and the spring guide rods pass through the two rectangular sliding cavities on the H-shaped tube 202. The 205 slides with a pinch plate 203, and the lower ends of the two pinch plates 203 are fixedly connected with limit rods 204. A spring is sleeved on the outside of the spring guide rod 205, and a handle is provided on the pinch plate 203. A clamp 3 is provided on the upper part of the I-shaped sliding seat 2. The upper end of the clamp base 1 holds the gear ring workpiece 4 through the clamp 3. Through the cooperation of the I-shaped sliding seat 2, the H-shaped tube 202, the pinch plate 203, the limit rod 204, the T-shaped slide groove 101 and the limit hole 103, the position of the clamp 3 can be adjusted according to the size of the gear ring workpiece 4. During the adjustment process, no tools are needed, which is convenient and time-saving, and significantly improves the processing efficiency of the gear ring workpiece 4.

[0031] The limiting rod 204 passes through one side of the H-shaped tube 202 and the lower side of the I-shaped sliding seat 2; when the I-shaped sliding seat 2 is in a limited state inside the T-shaped slide groove 101, the limiting rod 204 is inserted into the limiting hole 103, so that the I-shaped sliding seat 2 can be quickly and effectively limited on the fixture base 1.

[0032] The bottom surface of the fixture base 1 has rectangular openings 102 arranged in a ring array, and the rectangular openings 102 communicate with the T-shaped slide 101. The width of the rectangular openings 102 is equal to the width of the lower side of the T-shaped slide 101. The rectangular openings 102 facilitate the cleaning of iron filings.

[0033] The fixture 3 includes a clamping plate 301 and a clamping screw 303. A sliding rod 302 that passes through the I-shaped sliding seat 2 is fixedly connected to the bottom end face of the clamping plate 301, and the sliding rod 302 is slidably connected to the I-shaped sliding seat 2. The clamping screw 303 is fixedly connected to the top end face of the I-shaped sliding seat 2, and the clamping screw 303 passes through the clamping plate 301. A fixing nut 304 is threadedly connected to the upper outer end of the clamping screw 303 for clamping and fixing the gear ring workpiece 4.

[0034] Example 2, based on Example 1, such as Figure 3 and Figure 6 As shown, it also includes an anti-loosening component 5, which is disposed on the top of the clamping plate 301. The anti-loosening component 5 includes a rectangular slide cylinder 501 and a locking gear 502. The rectangular slide cylinder 501 is fixedly connected to the top surface of the clamping plate 301, and a rectangular slider 503 is slidably connected inside the rectangular slide cylinder 501. A locking block 504 is fixedly connected to the head end face of the rectangular slider 503. The locking gear 502 is fixedly connected to the bottom end face of the fixing nut 304. A spring is provided inside the rectangular slide cylinder 501 at the tail end of the rectangular slider 503, and a strip-shaped opening is provided on the upper end face of the rectangular slide cylinder 501. A limit slider 505 is fixedly connected to the upper end face of the rectangular slider 503, and the limit slider 505 is connected to the rectangular slide cylinder 501. The upper end face has a strip-shaped opening for sliding connection, and the upper end face of the limiting slider 505 is rotatably connected to the rotating block 506 via a rotating shaft. The top of the rectangular slide cylinder 501 is fixedly connected to the L-shaped limiting block 507. When the anti-loosening component 5 is in the anti-loosening state, the locking block 504 meshes with the locking gear 502. With the setting of the anti-loosening component 5, after the gear ring workpiece 4 is fixed, the locking block 504 meshes with the locking gear 502 to effectively lock and limit the fixing nut 304. Thus, even in a continuous vibration environment, the fixing nut 304 can be prevented from loosening. This not only improves the firmness of clamping the gear ring workpiece 4, but also ensures the processing accuracy and finished product quality of the gear ring workpiece 4.

[0035] The working principle of this embodiment is as follows: In use, first place the gear ring workpiece 4 on the middle of the upper end face of the fixture base 1, and then adjust the position of the fixture 3 according to the size of the gear ring workpiece 4. During adjustment, manually squeeze the handles on the two adjacent pinch plates 203 in opposite directions at the same time, so that the corresponding two pinch plates 203 and the two limiting rods 204 move towards each other at the same time, so that the limiting rods 204 are pulled out from the limiting insertion hole 103, so that the I-shaped sliding seat 2 loses its fixing function in the T-shaped slide groove 101. Then slide the I-shaped sliding seat 2 to adjust the position of the fixture 3. After the position of the fixture 3 is adjusted, release the pinch plates 203. At this time, the two adjacent pinch plates 203 move in opposite directions at the same time under the action of the spring force of the spring guide rod 205, so that the corresponding two limiting rods 204 are inserted into the limiting insertion hole 103, so that the fixture 3 in the adjusted position can be quickly positioned.

[0036] After adjusting the position of clamp 3, manually rotate the rotating block 506 upwards to a vertical position. Then, the rotating block 506 moves the rectangular slider 503 and locking block 504 towards the tail end of the rectangular slide cylinder 501. Next, rotate the rotating block 506 to a horizontal position, so that the rotating block 506 is locked onto the L-shaped limit block 507, thus limiting the rectangular slider 503 and locking block 504. Then, rotate the fixing nut 304 clockwise with a wrench, so that the locking gear 502 is pressed tightly against the top surface of the clamping plate 301. Then, the clamping plate 301 is pressed tightly against the inner side of the upper end face of the gear ring workpiece 4, so that the gear ring workpiece 4 is effectively clamped. Then, the rotating block 506 and the L-shaped limit block 507 are separated. When the rectangular slider 503 and locking block 504 are released, they lose their limiting function. At this time, under the action of the spring force at its tail end, the rectangular slider 503 moves the locking block 504 towards the locking gear 502, so that the locking block 504 meshes with the locking gear 502. This allows the fixing nut 304 to be effectively locked and limited, so that even if it is affected by continuous vibration, the fixing nut 304 will not loosen, thus avoiding the gradual weakening of the clamping force of the fixture 3 on the gear ring workpiece 4. This effectively improves the firmness and ensures the machining accuracy and finished product quality of the gear ring workpiece 4. After the gear ring workpiece 4 is clamped and fixed, it can be drilled by the drilling device on the drilling machine.
