[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Example:

[0020] Please see the appendix Figure 1 As shown, this embodiment provides a high-precision clamping and support device for bar stock, which includes a clamping member 1, a support member 2, a position adjustment mechanism 3, and an angle adjustment mechanism 4. The clamping member 1 can clamp one end of the bar stock. The support member 2 is spaced apart from the clamping member 1 and is independently arranged. The position adjustment mechanism 3 can adjust the horizontal and vertical distance between the support member 2 and the clamping member 1. The angle adjustment mechanism 4 is connected between the position adjustment mechanism 3 and the support member 2 and can adjust the horizontal and vertical angles of the support member 2 relative to the clamping member 1. That is, the position adjustment mechanism 3 and the angle adjustment mechanism 4 can work together to adjust the position (i.e., position and attitude) of the support member 2 relative to the clamping member 1 according to processing requirements, so that the support member 2 can provide adaptive and precise support for the bar stock.

[0021] Understandably, this application can quickly, accurately, and adaptively adjust the position of the support member 2 relative to the clamping member 1 according to the processing requirements of bar stock, especially slender bar stock, so as to enable the support member 2 and the clamping member 1 to work together to quickly and accurately support and clamp the bar stock B, thereby effectively avoiding the problems of bar stock deformation and unstable processing accuracy caused by imperfect / inadequate support in the prior art. Therefore, the clamping and support device of this application can greatly improve the processing accuracy and efficiency of bar stock, and well meet the needs of precision and / or high precision processing.

[0022] The following is a detailed description of the specific structure of the high-precision clamping and support device for bar stock described in this embodiment.

[0023] First, please refer to the appendix. Figure 1 and 2 As shown, in the high-precision clamping and support device structure for bar stock described in this embodiment, the position adjustment mechanism 3 includes a first translation member 30 capable of reciprocating and positioning along a first horizontal direction, a lifting assembly 31 disposed on the first translation member 30 and capable of outputting lifting power, and a second translation member 32 disposed on the power output end of the lifting assembly 31 and capable of slight movement and positioning along a second horizontal direction, wherein the first horizontal direction is perpendicular to the second horizontal direction. It is understood that the position adjustment mechanism 3 can realize position adjustment functions in two different horizontal directions and a position adjustment function in the vertical direction, thereby enabling precise adjustment of the horizontal and vertical distances between the support member 2 and the clamping member 1.

[0024] Furthermore, to better meet the load-bearing function, the first translation member 30 in this embodiment preferably adopts a flat plate structure, and the method by which the first translation member 30 can reciprocate and position itself along the first horizontal direction in this embodiment is as follows: Please refer to the appendix. Figure 2 As shown, the position adjustment mechanism 3 also includes a linear slide module 33 (specifically, a combination of a motor and a lead screw module). The power output end of the linear slide module 33 can reciprocate and position itself along the first horizontal direction and is simultaneously fixedly connected to the first translation member 30. Understandably, the linear slide module 33 can drive the first translation member 30 to perform high-precision, high-efficiency, high-safety, and wide-range horizontal linear motion. Thus, when processing slender bars, as the force points on the bar change, the linear slide module 33 can quickly and accurately drive the support member 2 to support different positions on the slender bar, effectively ensuring the stability of the bar processing.

[0025] Furthermore, in this embodiment, the preferred implementation structure of the lifting assembly 31 is as follows: Please refer to the appendix. Figure 2 To be continued Figure 6As shown, the lifting assembly 31 includes a cylinder 310, a piston rod 311 inserted in the cylinder 310 and capable of moving up and down under the action of hydraulic oil, and a limiting assembly capable of controlling the upward stroke of the piston rod 311. The cylinder 310 is provided with an oil injection hole. The principle of the piston rod 311 moving up and down under the action of hydraulic oil is similar to the working principle of a hydraulic cylinder, which is common knowledge and will not be described in detail here. Furthermore, the upper end of the piston rod 311 extending outside the cylinder 310 is the power output end of the lifting assembly 31. The limiting assembly includes an adjusting screw 312, a guide sleeve 313, a connecting piece 314, and... A locking screw 315 is used to screw the adjusting screw 312 onto the cylinder 310, with its lower end inserted into the cylinder 310 and its upper end extending out of the cylinder 310 in a sealed manner. A retaining member 316 with a snap ring structure is also fitted onto the adjusting screw 312 near its upper end. The guide sleeve 313 is loosely fitted onto the lower end of the adjusting screw 312 and simultaneously fixedly connected to the lower end of the piston rod 311 via the connecting member 314. The locking screw 315 can tighten and fix the retaining member 316 onto the adjusting screw 312 while also locking the retaining member 316 onto the inner wall of the cylinder 310. It is understood that before the clamping support device described in this application operates normally, the retaining component can be adjusted according to the bar stock processing requirements to adjust the upward stroke of the piston rod 311. The specific adjustment method for the limiting component is as follows: First, unscrew the locking screw 315 outwards by a set length, so that the limiting member 316 is loosened but not disengaged from the adjusting screw 312; then, according to the processing requirements, operate the adjusting screw 312 to screw it inwards or outwards by a set distance (this set distance is generally small and belongs to micro-adjustment), and then screw the locking screw 315 inwards to lock the limiting member 316. Based on the above micro-adjustment of the position of the adjusting screw 312, the upward movement stroke of the guide sleeve 313 can be micro-adjusted, and thus the upward movement stroke of the piston rod 311 can be micro-adjusted.

[0026] Further explanation: ① In this embodiment, both the upper end of the adjusting screw 312 and the locking screw 315 are provided with precision fine threads. Based on these precision fine threads, not only is self-locking and anti-loosening more convenient, but a good sealing effect can also be achieved. ② In this embodiment, the guide sleeve 313 and the adjusting screw 312 are fitted with a clearance fit, which can effectively prevent interference between the adjusting screw 312 and the piston rod 311. For example, when the adjusting screw 312 is rotated, the clearance fit between the adjusting screw 312 and the guide sleeve 313 can prevent it from interfering with the piston rod 311, thereby improving the safety of the lifting assembly 31.

[0027] Furthermore, to better meet the load-bearing function, in this embodiment, the second translation member 32 preferably adopts a block structure with a planar upper surface. The method by which the second translation member 32 can move and be positioned slightly along the second horizontal direction in this embodiment is as follows: Please refer to the appendix. Figure 2 Appendix Figure 7 and attached Figure 8 As shown, the position adjustment mechanism 3 further includes a mounting base 34, a guide rod 35, an adjusting screw 36, and a pre-tightening member 37. The mounting base 34 is a U-shaped structure and is fixedly connected to the power output end of the lifting assembly 31 (i.e., the upper end of the piston rod 311) via a connecting block 38. The guide rod 35 moves through the second translation member 32 and is mounted on the mounting base 34 together with the second translation member 32. The adjusting screw 36 passes through one side of the mounting base 34 along the second horizontal direction and abuts against or is fixedly connected to the second translation member 32 to drive the second translation member 32 to move slightly along the second horizontal direction. The pre-tightening member 37 is connected to the opposite side of the mounting base 34 along the second horizontal direction and can apply an elastic preload along the second horizontal direction to the second translation member 32. Understandably, by rotating the adjusting screw 36 by external force, the second translation member 32 can be driven to move back and forth slightly along the second horizontal direction. During the slight movement of the second translation member 32, the pre-tightening member 37 will continuously provide elastic pre-pressure to the second translation member 32, thereby ensuring that the movement distance of the second translation member 32 is more accurate.

[0028] Further explanation: ① Please refer to the appendix. Figure 8 As shown, the second translation member 32 has a through hole 320 extending along the second horizontal direction for the guide rod 35 to pass through, and a slot 321 on the side of the second translation member 32 facing the preload bolt 370 for movably receiving one end of the preload bolt 370. ② The preferred structure of the preload member 37 is: Please refer to the appendix. Figure 8 As shown, the preload member 37 includes a preload bolt 370 mounted on the opposite side of the mounting base 34 along the second horizontal direction and a disc spring 371 sleeved on the preload bolt 370 and simultaneously elastically abutting between the mounting base 34 and the second translation member 32.

[0029] Next, please refer to the appendix. Figure 2 Appendix Figure 9 and attached Figure 10As shown, in the high-precision clamping and support device structure for bar stock described in this embodiment, the angle adjustment mechanism 4 includes a first adjustment seat 41, a second adjustment seat 42, a first adjustment component, and a second adjustment component. The first adjustment seat 41 is disposed on the upper side of the second translation member 32 and can be horizontally rotated and positioned around the center of the second translation member 32 under the action of the first adjustment component. The upper part of the first adjustment seat 41 forms a vertically arranged bifurcation structure 410. The second adjustment seat 42 is inserted into the bifurcation structure 410 and is rotatably connected to the bifurcation structure 410 through a rotating shaft 40 (or can be understood as a movable connection). The second adjustment seat 42 can also be vertically oscillating and positioned relative to the vertical center line of the bifurcation structure 410 under the action of the second adjustment component. Understandably, the angle adjustment mechanism 4 can realize the horizontal angle adjustment function (specifically implemented by the first adjustment component controlling the first adjustment seat 41) and the vertical angle adjustment function (specifically implemented by the second adjustment component controlling the second adjustment seat 42), thereby realizing the adjustment of the horizontal and vertical angles of the support member 2 relative to the clamping member 1.

[0030] Furthermore, in this embodiment, the first adjustment component enables the first adjustment seat 41 to be horizontally rotated and positioned around the center of the second translation member 32 in the following manner: Please refer to the appendix. Figure 9 and 10 As shown, the bottom of the first adjusting seat 41 is a flat plate structure, and the bottom of the first adjusting seat 41 is rotatably mounted on the center position of the upper side of the second translation member 32 via a central shaft (not shown in the figure); the first adjusting assembly is provided with an eccentric pin 44 and a locking bolt A45. The small diameter end of the eccentric pin 44 is inserted into the second translation member 32 with a gap, and the large diameter section of the eccentric pin 44 is fixedly embedded in the bottom of the first adjusting seat 41. By applying an external force to rotate the eccentric pin 44, the first adjusting seat 41 can be synchronously driven to rotate horizontally around the center of the second translation member 32 (Note: the horizontal rotation of the first adjusting seat 41 is a micro-rotation); after the position of the first adjusting seat 41 is adjusted by rotating the eccentric pin 44, the locking bolt A45 can lock and fix the first adjusting seat 41 to the upper side of the second translation member 32.

[0031] Further explanation: ① Please refer to the appendix. Figure 8 As shown, the second translation member 32 is provided with a central hole 322 that rotatably mates with the central shaft, a receiving hole 323 that mates with the small-diameter end clearance of the eccentric pin 44, and a threaded mounting hole 324 that screws into the locking bolt A45. Please refer to the appendix for further details. Figure 9 and 10As shown, the bottom of the first adjusting seat 41 is provided with an insert hole 411 for fixedly fitting the large-diameter section of the eccentric pin 44 and a countersunk hole 412 for mounting the locking bolt A45. ② The inner diameter of the countersunk hole 412 is approximately 2mm larger than the outer diameter of the head of the locking bolt A45, and the inner diameter of the receiving hole 323 is also approximately 2mm larger than the outer diameter of the small-diameter end of the eccentric pin 44, to meet the adjustment space requirements.

[0032] Furthermore, in this embodiment, the second adjustment component is configured to vertically swing and position the second adjustment seat 42 relative to the vertical center line of the bifurcated structure 410 as follows: Please refer to the appendix. Figure 9 and 10 As shown, the second adjustment assembly is provided with an adjusting bolt 46 and a locking bolt B47. The adjusting bolt 46 is screwed through the bifurcated structure 410 and fixedly connected to the bottom of the second adjustment seat 42. A spring (not shown in the figure, but a disc spring can be used) that can apply elastic pressure to the second adjustment seat 42 is also sleeved on the adjusting bolt 46. After the position of the second adjustment seat 42 is adjusted by rotating the adjusting bolt 46, the locking bolt B47 can lock and fix the second adjustment seat 42 to the bifurcated structure 410.

[0033] Further explanation: ① Please refer to the appendix. Figure 9 and 10 As shown, the axial directions of the rotating shaft 40 and the locking bolt B47 are parallel to the second horizontal direction, and the axial direction of the adjusting bolt 46 is perpendicular to the axial direction of the rotating shaft 40. ② The bifurcated structure 410 is provided with a mounting hole (not shown in the figure) for mounting the rotating shaft 40 and a countersunk hole A (not shown in the figure) for mounting the locking bolt B47. The inner diameter of the countersunk hole A is approximately 2mm larger than the outer diameter of the head of the locking bolt B47 to meet the adjustment space requirements. ③ The middle part of the rotating shaft 40 is threadedly connected to the second adjusting seat 42, and both ends of the rotating shaft 40 are respectively fitted with the mounting holes on the bifurcated structure 410 with clearance fit.

[0034] Next, please refer to the appendix. Figure 9 and 10 As shown, in the high-precision clamping and support device structure for bar stock described in this embodiment, the support member 2 is provided with two sets of support bearing assemblies arranged side by side and rotatably mounted on the top of the second adjustment seat 42. The two sets of support bearing assemblies cooperate to support the bar stock portion placed between them.

[0035] For further details, please refer to the appendix. Figure 9 and 10As shown, the second adjusting seat 42 has two sets of lugs on its top, each lug consisting of a pair of lugs 420. Each set of support bearing assemblies has a pin 20 rotatably mounted on one set of lugs and at least one bearing 21 sleeved on the pin 20. Understandably, based on the bar stock size, the two sets of support bearing assemblies can provide planar support or "V" support for the bar stock, offering excellent applicability. Furthermore, this embodiment also includes a recessed clearance groove 421 on the top of the second adjusting seat 42, located between the two sets of lugs, for avoiding interference with the bar stock. When the two sets of support bearing assemblies provide "V" support for the bar stock, the clearance groove 421 effectively avoids interference, improving the support effect on the bar stock.

[0036] Please continue to refer to the appendix. Figure 1 As shown, in the high-precision clamping and support device structure for bar stock described in this embodiment, the clamping member 1 is a collet; the high-precision clamping and support device also includes a bracket 50 that is spaced apart from the adjusting mechanism along the first horizontal direction, and a DD motor 51 mounted on the bracket 50 and capable of driving the clamping member 1 to rotate. It is understood that the DD motor 51 enables the bar stock to be rotated. Furthermore, as can be seen from the structure of the support member 2, when the DD motor 51 drives the bar stock to rotate, the support member 2 provides precise support while effectively protecting the bar stock from frictional damage.

[0037] Finally, the prefixes "first," "second," etc., of the component names in this specification (such as first translation component, second translation component, etc.) and the suffixes "A," "B," etc., of the component names (such as locking bolt A, locking bolt B, etc.) are only for ease of description and are not intended to limit the scope of implementation of this invention.

[0038] In summary, the high-precision clamping and support device for bar stock described in this invention has a simple and reasonable structure, and is easy and flexible to operate. It can not only achieve rapid and accurate support and clamping of bar stock, greatly improving the processing accuracy and efficiency of bar stock products and meeting the needs of precision and / or high-precision processing, but also is applicable to bar stock of several different sizes, with excellent versatility.
