Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically a multi-swashplate universal drilling and milling fixture. Background Technology

[0002] A fixture is a process device used during machining to quickly secure a workpiece and maintain the correct relative position of the machine tool, cutting tool, and workpiece. Fixtures are indispensable components in machining. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite, intelligent, and environmentally friendly directions, fixture technology is developing towards high precision, high efficiency, modularity, combination, versatility, and economy.

[0003] Currently, existing swashplate fixtures require repeated adjustments when installing the swashplate, especially during milling, as the swashplate's outline is not a regular plane. This makes the clamping and fixing process time-consuming, especially in milling operations where the top of the swashplate needs to be held horizontally. Furthermore, the machining angle of the swashplate is easily limited by its own outline, requiring the removal of the rotating face. When installing the rotating face, the milled surface can be used as the machined surface, making assembly simpler and more convenient. Therefore, these fixtures do not meet current requirements. To address this, we propose a multi-swashplate universal drilling and milling fixture. Utility Model Content

[0004] This utility model provides a universal swashplate fixture for drilling and milling, which has the advantages of being able to clamp the swashplate in both upright and inverted positions, quickly and conveniently aligning the swashplate machining surface during clamping, and enabling CNC automation, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a multi-swashplate universal drilling and milling fixture, including a forward clamping station and a reverse clamping station, both of which are set on a tooling plate. The forward clamping station includes two parallel support stands, each with an inner groove for placing the swashplate. The tooling plate has locking arms located on the outer side of the two support stands. The locking arms clamp the swashplate onto the support stands by moving toward the swashplate. The tooling plate also has a leveling arm for pressing the swashplate from the top. The reverse clamping station includes a horizontally set base, with clamping arms on both sides of the base that rotate vertically. The clamping arms lock the swashplate onto the base.

[0006] In this invention, the swashplate is clamped and fixed in two positions: a forward clamping position and an inverted clamping position. This facilitates milling and drilling operations on the machine tool. When the swashplate is placed in the forward clamping position, it is pressed by the alignment arm, causing its top to be horizontally aligned with the inner groove of the two support stands. The two locking arms clamp and fix the swashplate by moving closer together. After fixing, the alignment arm releases the swashplate and moves away from directly above it, facilitating machine tool processing. When the swashplate is placed in the inverted clamping position, the clamping arms on both sides of the base clamp the sides of the swashplate by vertical rotation. Because the top of the swashplate has good flatness, the swashplate will not wobble left or right after the symmetrical clamping arms press down, facilitating machine tool processing.

[0007] As an optional solution for a multi-swashplate universal drilling and milling fixture described in this utility model, the tooling plate is provided with a third driving device for driving the alignment arm to move up and down. The alignment arm is rotatably mounted on the driving end of the third driving device. At least two alignment pins are provided on the alignment arm along the center line between the two support seats. The bottom of the alignment pins abuts against the top of the swashplate.

[0008] As an optional solution for a multi-swashplate universal drilling and milling fixture described in this utility model, the support base is provided with weight pads symmetrically arranged along the center line of the inner groove. The weight pads are fixed to the inner groove by bolts, and the outer wall of the weight pads is in contact with the outer wall of the swashplate.

[0009] As an optional solution for the multi-sloping plate universal drilling and milling fixture described in this utility model, the bottom of each support stand is provided with a positioning groove, and a positioning strip connecting two support stands is provided in the positioning groove. The positioning strip connects and fixes the two support stands through the positioning groove.

[0010] As an optional solution for a multi-swashplate universal drilling and milling fixture described in this utility model, the tooling plate is provided with a first driving device for driving the left and right displacement of any one of the locking arms.

[0011] As an optional solution for a multi-swashplate universal drilling and milling fixture described in this utility model, the first driving device includes a first hydraulic cylinder. The telescopic end of the first hydraulic cylinder is provided with a power rod having an inclined sliding surface. A thrust slider is mounted on the power rod. The tooling plate is provided with a housing that locks the upper and lower positions of the thrust slider. As the power rod moves, the thrust slider slides left and right on the housing along its inclined sliding surface to push the locking arm.

[0012] As an optional solution for a multi-swashplate universal drilling and milling fixture described in this utility model, the tooling plate is provided with a second driving device for driving the clamping arm to rotate vertically.

[0013] As an optional solution for a multi-swashplate universal drilling and milling fixture described in this utility model, the second driving device includes a second hydraulic cylinder, the telescopic end of the second hydraulic cylinder is pinned to the end of the clamping arm, and a positioning link is pinned to the side of the clamping arm near the second hydraulic cylinder, the bottom of the positioning link being pinned to the outside of the housing of the second hydraulic cylinder.

[0014] As an optional solution for a multi-swashplate universal drilling and milling fixture described in this utility model, the base is provided with an angular positioning diamond pin to prevent the swashplate from rotating, and the outer wall of the diamond pin abuts against the outer wall of the swashplate.

[0015] As an optional solution for a multi-swashplate universal drilling and milling fixture described in this utility model, the tooling plate is provided with assembly side plates on both sides, and the tooling plate is mounted on a four-axis chuck through the assembly side plates.

[0016] This utility model has the following beneficial effects:

[0017] 1. In the positive clamping position of this type of multi-swashplate universal drilling and milling fixture, the aligning arm presses the flat top of the swashplate to make its top horizontal. After the swashplate is subjected to force, it slides in the inner groove of the two support seats and fits against the support seats. The two locking arms clamp the two sides of the swashplate by moving closer to each other, thereby fixing the swashplate. After fixing, the aligning arm releases the swashplate and moves away from directly above the swashplate to facilitate machine tool processing.

[0018] 2. In the positive clamping position of this multi-swashplate universal drilling and milling fixture, the swashplate is aligned by setting alignment pins, and at least two alignment pins push the swashplate to avoid the top of the swashplate being uneven before milling, which would cause machining errors and thus improve the milling accuracy.

[0019] 3. In the positive clamping position of this type of multi-swashplate universal drilling and milling fixture, by installing weight pads on the inner groove, wear can be reduced. Furthermore, by installing weight pads with different thicknesses and outer wall contours, the support stand can fit with different models of swashplates, thereby increasing the applicability while maintaining clamping stability.

[0020] 4. In the reverse clamping station of this type of multi-swashplate universal drilling and milling fixture, the clamping arms on both sides of the base clamp the two sides of the swashplate by vertical rotation. Since the top of the swashplate has good flatness, the swashplate will not wobble left and right after the symmetrical clamping arms are pressed down, so that the machine tool can perform processing.

[0021] 5. In the inverted clamping station of this type of multi-swashplate universal drilling and milling fixture, the diamond-shaped pins abut against the outer wall of the swashplate, thereby preventing the swashplate from rotating.

[0022] 6. In this type of multi-swashplate universal drilling and milling fixture, the first drive device, the second drive device, and the third drive device can all be controlled by CNC. Furthermore, through the four-axis chuck, the fixture can be automated to reduce labor intensity, improve machining accuracy, and accelerate production efficiency. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1: This example aims to facilitate solutions to the problems of improving machining efficiency, enhancing machining accuracy, and completing both the upright and inverted clamping of a swashplate on a single tooling fixture. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A multi-slant universal drilling and milling fixture includes a forward clamping station 1 and a reverse clamping station 2. Both the forward clamping station 1 and the reverse clamping station 2 are set on a fixture plate 3. Assembly side plates 300 are provided on both sides of the fixture plate 3. The fixture plate 3 is set on a four-axis chuck 301 through the assembly side plates 300.

[0035] In this embodiment, the swashplate can be clamped in the forward position and in the reverse position respectively through the forward clamping station 1 and the reverse clamping station 2, so as to facilitate milling and drilling operations on the machine tool. Moreover, the multi-swashplate universal drilling and milling fixture can be directly installed on the four-axis chuck 301 through the mounting side plate 300, so as to facilitate CNC automation control, thereby improving machining accuracy and machining efficiency.

[0036] Example 2 aims to improve the solutions to the problems of proper clamping and alignment of the swashplate. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8The clamping station 1 includes two parallel support stands 10, each with a placement groove 100 for placing a swashplate. The swashplate is placed in the placement groove 100 of the two support stands 10. A tooling plate 3 is located on the outside of the two support stands 10 and has locking arms 11. The locking arms 11 clamp the swashplate onto the support stands 10 by moving towards the swashplate. The tooling plate 3 is equipped with a first driving device that drives the left and right displacement of any one of the locking arms 11. The first driving device includes a first hydraulic cylinder 30, and the telescopic end of the first hydraulic cylinder 30 is provided with a swashplate. A power rod 31 with a sliding surface is mounted on the power rod 31, and a push slider 32 is mounted on the power rod 31. The push slider 32 is kept in a fixed position in the vertical direction. When the power rod 31 moves up and down, its push slider 32 moves left and right along its inclined sliding surface. The tooling plate 3 is provided with a housing 33 that locks the vertical position of the push slider 32. As the power rod 31 moves, the push slider 32 slides left and right along its inclined sliding surface on the housing 33 to push the locking arm 11. The locking arm 11 and the push slider 32 are fixedly connected by bolts, so that when the push slider 32 is retracted, the locking arm 11 can disengage from the swashplate to release the clamp.

[0037] The tooling plate 3 is also provided with a aligning arm 12 for pressing the swashplate from the top. The tooling plate 3 is provided with a third drive device for driving the aligning arm 12 to move up and down. The aligning arm 12 is rotatably mounted on the drive end of the third drive device. Rotating the aligning arm 12 can open the positive clamping station 1 to facilitate the placement of the swashplate. At least two aligning pins 120 are provided on the aligning arm 12 along the center line between the two support seats 10. The bottom of the aligning pins 120 abuts against the top of the swashplate.

[0038] In this embodiment: the alignment arm 12 presses the flat top of the swashplate by the alignment pin 120, making its top horizontal. After the swashplate is subjected to force, it slides in the inner groove 100 of the two support seats 10 and fits against the outer wall of the support seats 10, thereby leveling the machining surface of the swashplate to facilitate machine tool processing.

[0039] It should be noted that the alignment pin 120 and the alignment arm 12 are connected by a threaded structure, which allows the downward extension length of the alignment pin 120 to be adjusted, and the alignment pin 120 can also be distributed in a triangular shape for more precise alignment.

[0040] Example 3 aims to improve the applicability and versatility of this multi-swashplate universal drilling and milling fixture. This example is an improvement upon Example 2. For details, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8The support stand 10 is symmetrically provided with weight pads 101 along the center line of the inner groove 100. The weight pads 101 are fixed to the inner groove 100 by bolts. The outer wall of the weight pads 101 is in contact with the outer wall of the inclined plate. The weight pads 101 installed by bolts can be replaced and installed at any time to facilitate the adjustment of the weight pads 101.

[0041] Each support base 10 has a positioning groove 102 at its bottom. The positioning groove 102 contains a positioning strip 103 that connects the two support bases 10. The positioning strip 103 connects and fixes the two support bases 10 through the positioning groove 102.

[0042] In this embodiment: by installing weight pads 101 with different thicknesses and outer contours, the support stand can fit with different models of swashplates. The distance between the two support stands 10 can be shortened or widened. When moving the support stand 10, the support stand 10 moves along the positioning strip 103 through the positioning groove 102, which can prevent the support stand 10 from being misaligned during adjustment, thereby increasing the applicability of the special clamp while maintaining clamping stability.

[0043] Example 4 aims to improve the solution to the problem of stable inverted clamping of swashplate components. This example is an improvement on Example 1. For details, please refer to Example 4. Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 The inverted clamping station 2 includes a horizontally arranged base 20. The base 20 has clamping arms 21 that rotate vertically on both sides. When the clamping arms 21 rotate vertically downward, they can lock the swashplate onto the base 20. When the clamping arms 21 rotate vertically upward, they can release the clamp. The base 20 is provided with angular positioning diamond pins 200 to prevent the swashplate from rotating. The diamond-shaped outer wall of the angular positioning diamond pins 200 abuts against the outer wall of the swashplate.

[0044] The tooling plate 3 is provided with a second driving device for driving the clamping arm 21 to rotate vertically. The second driving device includes a second hydraulic cylinder 22. The telescopic end of the second hydraulic cylinder 22 is pinned to the end of the clamping arm 21. A positioning link 23 is also pinned to the side of the clamping arm 21 near the second hydraulic cylinder 22. The bottom of the positioning link 23 is pinned to the housing of the second hydraulic cylinder 22. The second hydraulic cylinder 22 pushes the clamping arm 21 to rotate vertically up and down. When the clamping arm 21 rotates, the positioning link 23 connects the clamping arm 21 to the housing of the second hydraulic cylinder 22 by means of pinning, so that the clamping arm 21 can be stably clamped by the second hydraulic cylinder 22.

[0045] In this embodiment, the clamping arm 21 presses down to clamp and fix the swashplate, thereby fixing the suction cup with at least one flat surface by inverted clamping, so as to facilitate subsequent drilling and milling processing by the machine tool.

[0046] In this multi-swashplate universal drilling and milling fixture, the first drive device, the second drive device, and the third drive device can all be controlled by CNC. Furthermore, through the four-axis chuck 301, the fixture can be automated to reduce labor intensity, improve machining accuracy, and accelerate production efficiency.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
