Description

Technical Field

[0001] This utility model relates to the field of model fixture technology, specifically a multi-angle tapping fixture for irregularly shaped model parts. Background Technology

[0002] In most industries, the connection between model workpieces is usually fixed by bolts. Therefore, after the model is made, it needs to be tapped to make screw holes so that bolts can be used for later connection.

[0003] Conventional model workpieces can be fixed by simply pressing them down, and then tapping can be performed on them. However, it is difficult to fix irregularly shaped parts and keep them from shaking during the tapping process. Therefore, a fixture is needed to fix irregularly shaped model parts for tapping. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a multi-angle tapping clamp for irregularly shaped models, which can clamp and fix models with irregular structures to facilitate tapping. The angle can also be adjusted during the fixing process to facilitate tapping of irregularly shaped parts at different angles.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a multi-angle tapping clamp for irregularly shaped model parts, including a support assembly. The support assembly includes two horizontal rings and a bracket. A connecting rod is fixedly connected to each of the two horizontal rings. The connecting rod is fixedly connected between the bracket and the horizontal ring. An adjustment assembly is provided on the two horizontal rings. The adjustment assembly includes a slip ring, a connecting tube, a gasket, a bracket, a fixing tube, and a telescopic rod. The slip ring is slidably connected between the two horizontal rings. The two connecting tubes are fixedly connected to the slip ring. The two gaskets are fixedly connected to the two connecting tubes. The two brackets are fixedly connected to the two gaskets by bolts. Multiple fixing tubes are respectively fixedly connected to the two brackets. Multiple telescopic rods are respectively slidably connected to multiple fixing tubes. An inflation assembly is provided inside the two connecting tubes. A fixing assembly is provided on the slip ring.

[0006] Preferably, the adjustment assembly further includes a first spring and an air passage. The first springs are respectively fixedly connected between the inner walls of the multiple telescopic rods and the multiple fixed tubes. The two air passages are respectively opened inside the two supports and are respectively connected to the interior of the multiple fixed tubes.

[0007] Preferably, the inflation assembly includes partitions, one-way valves, and air holes. Two partitions are fixedly connected inside each of the two connecting pipes, four one-way valves are respectively disposed on the four partitions, and two air holes are respectively disposed on the two connecting pipes.

[0008] Preferably, the inflation assembly further includes buttons, pistons, and second springs. The two buttons are slidably connected to the two connecting tubes, the two pistons are fixedly connected to the two buttons, the two pistons are slidably connected to the partitions inside the two connecting tubes, and the two second springs are fixedly connected to the inner walls of the two connecting tubes and between the two pistons.

[0009] Preferably, the fixing assembly includes rotating rods, housings, and cones. Two rotating rods are fixedly connected to a slip ring, two housings are slidably connected to the two rotating rods respectively, and multiple cones are fixedly connected to the two housings respectively.

[0010] Preferably, the fixing assembly further includes magnetic blocks and iron rings, with two magnetic blocks respectively fixedly connected to two rotating rods, the two magnetic blocks respectively located inside the two housings, and four iron rings respectively fixedly connected to the inner walls of the two housings.

[0011] Compared with the prior art, the significant advantages of this utility model are:

[0012] Firstly, in this invention, two supports are bolted to two washers. The bolts are not tightened initially, leaving a gap between the supports and washers. The irregularly shaped model is then placed between the two supports. Multiple fixing tubes and telescopic rods clamp the model. Depending on the shape of the model, different telescopic rods retract into the fixing tubes by different lengths. As the telescopic rods retract, air from the fixing tubes enters the air passage and then exits through the gap between the supports and washers. Once the irregularly shaped model is stable between the two sets of fixing tubes and telescopic rods, the bolts are tightened. At this point, there is no gap between the washers and supports, and air cannot circulate in the fixing tubes. All telescopic rods are now fixed. To clamp the irregularly shaped model with the telescopic rods, the button can be pressed repeatedly. During this process, the air between the partitions is compressed by the piston, passes through one of the one-way valves, enters the air passage, and then enters each fixing tube, increasing the air pressure within the fixing tubes. This causes all the telescopic rods to press against the irregularly shaped model, firmly fixing it in place.

[0013] Secondly, in this utility model, after the irregular part is fixed, it can be tapped. When tapping is required at different angles, the slip ring can be rotated horizontally, and the two rotating rods on it can slide between the two horizontal rings. When the angle needs to be adjusted vertically, the two rotating rods can be rotated to make the entire slip ring rotate vertically. When the slip ring needs to be fixed, it is only necessary to slide the housing on the two rotating rods to bring the housing close to the horizontal ring. The magnetic block and iron ring inside the housing attract each other, causing the housing to move until the cone block and the surface of the horizontal ring are in contact. A leather ring is fitted on the surface of the horizontal ring, and the static friction between the leather ring and the cone block can ensure that the slip ring is fixed.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved multi-angle tapping fixture for irregularly shaped model parts. The technical solution of this utility model is as follows:

[0024] like Figures 1-5As shown, a multi-angle tapping fixture for irregularly shaped model parts includes a support assembly 1. The support assembly 1 includes two horizontal rings 11 and a bracket 13. A connecting rod 12 is fixedly connected to each of the two horizontal rings 11, and the connecting rod 12 is fixedly connected between the bracket 13 and the horizontal rings 11. An adjustment assembly 2 is provided on the two horizontal rings 11. The adjustment assembly 2 includes a sliding ring 21, a connecting pipe 22, a washer 23, a bracket 24, a fixing pipe 25, and a telescopic rod 26. The sliding ring 21 is slidably connected between the two horizontal rings 11, and the two connecting pipes 22 are fixedly connected to the sliding ring 21. On the ring 21, two gaskets 23 are fixedly connected to two connecting pipes 22, two brackets 24 are fixedly connected to two gaskets 23 by bolts, multiple fixing pipes 25 are fixedly connected to two brackets 24 respectively, and multiple telescopic rods 26 are slidably connected to multiple fixing pipes 25 respectively. An inflation component 3 is provided inside the two connecting pipes 22, and a fixing component 4 is provided on the slip ring 21. Multiple fixing pipes 25 and telescopic rods 26 are densely distributed. An angle scale line is provided on the surface of the slip ring 21 to facilitate observation of the rotation angle when it rotates horizontally.

[0025] Furthermore, the adjustment assembly 2 also includes a first spring 27 and an air passage 28. Multiple first springs 27 are fixedly connected between multiple telescopic rods 26 and the inner walls of multiple fixed tubes 25. Two air passages 28 are respectively opened inside two supports 24 and are respectively connected to the interior of multiple fixed tubes 25. When the irregular part model is placed between two symmetrical sets of fixed tubes 25 and telescopic rods 26, the elastic force of the first spring 27 is used to make the telescopic rods 26 tightly press against the surface of the irregular part. According to the shape of the irregular part, the telescopic rods 26 at different positions will retract to different lengths.

[0026] Furthermore, the inflation assembly 3 includes a partition 31, a one-way valve 35, and an air hole 36. Two partitions 31 are fixedly connected inside each of the two connecting pipes 22. Four one-way valves 35 are respectively set on the four partitions 31. Two air holes 36 are respectively set on the two connecting pipes 22. The air holes 36 can supply air into the connecting pipes 22, so that the air enters the connecting pipes 22 through the one-way valves 35, and then enters the air passage 28, which increases the air pressure in all the fixed pipes 25, so that the telescopic rod 26 can tightly press against the surface of the model part without retracting, thereby fixing the part.

[0027] Furthermore, the inflation assembly 3 also includes a button 32, a piston 33, and a second spring 34. The two buttons 32 are slidably connected to the two connecting tubes 22, and the two pistons 33 are fixedly connected to the two buttons 32. The two pistons 33 are slidably connected to the partitions 31 inside the two connecting tubes 22, and the two second springs 34 are fixedly connected between the inner walls of the two connecting tubes 22 and the two pistons 33. By repeatedly pressing the button 32, the pistons 33 can be controlled to move up and down. When the pistons 33 move upward, outside air enters the connecting tube 22 through the air hole 36. When the pistons 33 move downward, the air is squeezed to the other side and then enters the air passage 28.

[0028] Furthermore, the fixing component 4 includes a rotating rod 41, a housing 42, and a cone block 43. Two rotating rods 41 are fixedly connected to the slip ring 21, and two housings 42 are slidably connected to the two rotating rods 41 respectively. Multiple cone blocks 43 are fixedly connected to the two housings 42 respectively. The movement of the housings 42 can drive the cone blocks 43 to move. A rubber layer or leather layer is sleeved on the surface of the horizontal ring 11. When the cone blocks 43 are tightly pressed against its surface, the entire slip ring 21 can be fixed by using a large static friction force. An angle scale line is provided on the rotating rod 41. When it drives the slip ring 21 to rotate longitudinally, the angle can also be observed.

[0029] Furthermore, the fixing component 4 also includes a magnetic block 44 and iron rings 45. The two magnetic blocks 44 are respectively fixedly connected to the two rotating rods 41. The two magnetic blocks 44 are respectively located inside the two housings 42. The four iron rings 45 are respectively fixedly connected to the inner walls of the two housings 42. Since the iron rings 45 are located at both ends inside the housing 42, when the housing 42 is pushed or pulled, the two ends of the housing 42 can be attracted and fixed to the magnetic blocks 44 respectively. The positions where the two iron rings 45 are attracted and fixed to the magnetic blocks 44 respectively correspond to the positions where the cone block 43 and the horizontal ring 11 abut and separate respectively.

[0030] The specific working method is as follows: Two supports 24 are bolted to two washers 23, but the bolts are not tightened initially, leaving a gap between the supports 24 and the washers 23. The irregularly shaped model is then placed between the two supports 24. Multiple fixing tubes 25 and telescopic rods 26 will clamp the irregularly shaped model. Depending on the shape of the model, different telescopic rods 26 will retract into the fixing tubes 25 by different lengths. As the telescopic rods 26 retract, air inside the fixing tubes 25 enters the air passage 28 and then exits through the gap between the supports 24 and the washers 23. When the irregularly shaped model is within the gap between the two sets of fixing tubes 24... After the expansion rod 26 and the telescopic rod 26 are stabilized, tighten the bolts. At this time, there will be no gap between the gasket 23 and the bracket 24, and the air in the fixing tube 25 cannot flow. At this time, all the expansion rods 26 are fixed. In order to clamp the irregular part with the expansion rods 26, the button 32 can be pressed repeatedly. During the pressing of the button 32, the air between the partitions 31 will be squeezed by the piston 33, pass through one of the one-way valves 35, and then enter the air passage 28, and then enter each fixing tube 25, which will increase the air pressure in the fixing tube 25. At this time, all the expansion rods 26 will press against the irregular part, and fix the irregular part firmly.

[0031] Once the irregularly shaped part is fixed, it can be tapped. When tapping at different angles is required, the slip ring 21 can be rotated horizontally, and the two rotating rods 41 on it can slide between the two horizontal rings 11. When the angle needs to be adjusted vertically, the two rotating rods 41 can be rotated to make the entire slip ring 21 rotate vertically. When the slip ring 21 needs to be fixed, the housing 42 on the two rotating rods 41 can be slid to bring the housing 42 close to the horizontal ring 11. The magnetic block 44 and the iron ring 45 inside the housing 42 are attracted to each other, causing the housing 42 to move until the cone block 43 and the surface of the horizontal ring 11 are in contact. A leather ring is fitted on the surface of the horizontal ring 11. The static friction between the leather ring and the cone block 43 can ensure that the slip ring 21 is fixed.

Matters not covered in this utility model are common knowledge to those skilled in the art.
