Description

Technical Field

[0001] This application relates to the field of positioning and clamping technology, and in particular to a lateral positioning device. Background Technology

[0002] In the machining process, when machining parts, clamping and positioning tools are usually used to hold and position the parts, such as vises, chucks, suction cups, disks, and clamping blocks. These methods can usually meet the machining and clamping requirements of most parts. However, when milling or machining the end face of a part, the end face of the part cannot be pressed down by the positioning tool. Therefore, lateral positioning tools are used to achieve the positioning and clamping of the part.

[0003] A lateral positioning device, as disclosed in CN109848747A, includes a base, a connecting frame, and a rotating plate. A lateral positioning plate is fixedly mounted on the front end of the rotating plate. The connecting frame is fixedly mounted on the upper end of the base and is a U-shaped frame. The end of the rotating plate is located within the U-shaped groove of the connecting frame, and a through hole is provided at the end of the rotating plate. The through hole of the rotating plate is rotatably connected to the connecting frame by bolts. This invention has a simple structure, is easy to manufacture, and has low manufacturing cost. By adding a lateral positioning plate to the front end of the rotating plate, it can perform lateral positioning of an object, thereby achieving lateral positioning of the object.

[0004] First, the existing technology described above uses a side positioning plate to position the workpiece laterally. Since the side positioning plate is a strip panel, the existing technology can only position the side of a square workpiece and cannot position a round or polygonal workpiece laterally, which has certain limitations.

[0005] Secondly, when the workpiece is a boss-like structure with uneven top and bottom, the lateral positioning plate of the prior art cannot stably position and restrict the workpiece, resulting in workpiece positioning deviation and affecting workpiece processing. Summary of the Invention

[0044] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0045] Example 1:

[0046] See Figure 1 This application discloses a lateral positioning device, including a lateral positioning frame 1. Two positioners 2 are arranged vertically on the lateral positioning frame 1 for lateral positioning of the workpiece. The positioner 2 located at the upper end of the lateral positioning frame 1 is slidably arranged on the lateral positioning frame 1 by a lifting mechanism 3 for adjusting the distance between the upper and lower positioners 2.

[0047] This invention uses two positioners 2 to perform lateral positioning of the workpiece's side. At the same time, the invention uses a lifting mechanism 3 to adjust the distance between the two positioners 2, so that the positioner 2 located at the upper end of the lateral positioning frame 1 can press down and position the upper surface of the workpiece. Thus, this invention can not only perform lateral positioning of the workpiece in the horizontal direction, but also perform vertical downward pressing positioning of the workpiece.

[0048] See Figure 2-3The positioner 2 includes a side frame 21. The side frame 21 of the positioner 2 located at the lower end of the side positioning frame 1 is mounted on the side positioning frame 1. The side frame 21 of the positioner 2 located at the upper end of the side positioning frame 1 is mounted on the elevator 3, so that the elevator 3 can control the side frame 21 to move the positioner 2 at the upper end of the side positioning frame 1 up and down, thereby changing the distance between the two positioners 2.

[0049] A side plate 22 is fixed to one end of the side frame 21, and a positioning frame 23 is slidably provided at the other end of the side frame 21. A guide post 24 is connected to the end of the positioning frame 23 facing the side plate 22, and the end of the guide post 24 away from the positioning frame 23 slides through the side plate 22 and is connected to a limit block 25 to limit the movement of the positioning frame 23 within the side frame 21. A guide spring 26 is connected to the guide post 24 and located between the side plate 22 and the positioning frame 23. A positioning end 4 is provided on the side of the positioning frame 23 away from the side plate 22 for lateral positioning of the workpiece.

[0050] In the specific implementation process, when preparing to perform lateral positioning on the workpiece, first adjust the distance between the two positioners 2 according to the requirements. If only lateral positioning of the workpiece is required, push the lateral positioning frame 1 so that the positioning end 4 on the positioning frame 23 is driven to move towards the workpiece through the side frame 21 until the positioning end 4 contacts and abuts against the side of the workpiece. At this time, continue to push the lateral positioning frame 1 to move, so that the positioning frame 23 drives the guide column 24 to move towards the side plate 22 so that the guide spring 26 is compressed until the workpiece is laterally positioned and clamped.

[0051] Continue reading Figure 2-3 Based on the above process, since the guide spring 26 is an elastic element, the positioning end 4 may move towards the side plate 22, which may cause the positioning end 4 to fail to guarantee the lateral positioning of the workpiece. Therefore, the present invention provides a positioning component 27 between the side plate 22 and the positioning frame 23 to restrict the movement of the positioning frame 23.

[0052] Specifically, the positioning component 27 includes a positioning plate 271, which is located between the side plate 22 and the positioning frame 23. The end of the positioning plate 271 facing the side plate 22 is rotatably connected to a positioning screw 272, which passes through the side plate 22 and is threadedly connected to it. By turning the positioning screw 272, the position of the positioning plate 271 within the side frame 21 can be changed. When the positioning frame 23 moves to the positioning plate 271, the positioning screw 272 drives the positioning plate 271 to abut against the positioning frame 23, so that the positioning frame 23 cannot continue to move in the direction of compressing the guide spring 26. At this time, the side positioning of the workpiece by the positioning end 4 is completed.

[0053] The positioning screw 272 has balance bars 273 extending from both ends on the side away from the positioning frame 23, and the balance bars 273 slide through the side plate 22 to keep the positioning plate 271 stable.

[0054] Secondly, when dealing with a workpiece with a convex structure, the side of the workpiece is composed of at least two vertical planes. In this case, the positioning screw 272 can be turned to change the position of the positioning plate 271, thereby limiting the travel of the positioning frame 23 within the side frame 21, so as to ensure that the positioning ends 4 on both positioning devices 2 can be pressed against the side of the workpiece, and to ensure that the positioning frames 23 in the two positioning devices 2 are pressed against the positioning plate 271, so as to laterally position the convex structure workpiece.

[0055] In addition, the present invention limits the movement of the positioning frame 23 within the side frame 21 by changing the position of the positioning plate 271, so as to limit the vertical freedom of the workpiece by positioning the lower end face of the positioning end 4 at the upper end of the lateral positioning frame 1 with the upper surface of the workpiece.

[0056] Based on this, see Figure 4-5 The lifting mechanism 3 includes a return frame 31, which is slidably disposed within the side positioning frame 1. The side frame 21 located at the upper end of the side positioning frame 1 is disposed within the return frame 31. A lifting screw 32 is rotatably connected to the top of the return frame 31, and the upper end of the lifting screw 32 passes through the top of the side positioning frame 1 and is threadedly connected to the side positioning frame 1. By turning the lifting screw 32, the return frame 31 is driven to move up and down within the side positioning frame, thereby changing the distance between the two positioning ends 4. This ensures that the positioning end 4 located at the upper end of the side positioning frame is adapted to the convex structure of the workpiece, or ensures that the positioning end 4 located at the upper end of the side positioning frame can position the upper surface of the workpiece downwards, thus restricting the vertical freedom of the workpiece.

[0057] The side frame 21 is slidably disposed within the U-shaped frame 31 in the vertical direction, and a number of lifting springs 33 are connected between the bottom of the side frame 21 and the bottom of the U-shaped frame 31 to drive the side frame 21 to move upward; the bottom of the U-shaped frame 31 is provided with a control mechanism 34 for pulling the side frame 21 downward.

[0058] When the positioning end 4 located at the upper end of the side positioning frame positions the upper surface of the workpiece, the lifting screw 32 is used to move the positioning end 4 up and down to ensure that the lower surface of the positioning end 4 is above the upper surface of the workpiece. When the positioning end 4 can move smoothly to the upper surface of the workpiece, the side frame 21 is driven to move down under the action of the control mechanism 34, thereby driving the lower end of the positioning end 4 to press against the upper surface of the workpiece. This invention can not only position the workpiece laterally, but also position the upper surface of the workpiece while positioning the workpiece laterally.

[0059] The control mechanism 34 includes a sliding bar 341, which is slidably disposed at the bottom of the return frame 31 and slides along the moving direction of the positioning frame 23. Two horizontally arranged control screws 342 are threadedly connected to the sliding bar 341, and the axial direction of the control screws 342 is the same as the sliding direction of the sliding bar 341. One end of the control screw 342 away from the return frame 31 is placed below the positioning end 4 and slidably disposed on the support frame 343 provided at the lower end of the positioning end 4. A control wire rope 344 is connected to the upper end of the sliding bar 341, and the upper end of the control wire rope 344 passes through the return frame 31 and is connected to the side frame 21.

[0060] In the specific implementation process, as the lateral positioning frame 1 moves towards the workpiece, when the positioning end 4 at the lower end of the lateral positioning frame 1 begins to contact the side of the workpiece, the positioning end 4 at the upper end of the lateral positioning frame 1 moves to the upper surface of the workpiece until the control screw 342 located below the positioning end 4 begins to contact the side of the workpiece. This drives the control screw 342 to move the sliding bar 341 away from the workpiece. At this time, the sliding bar 341 pulls the control wire rope 344 to drive the side frame 21 to move down until the lower surface of the positioning end 4 is pressed against the upper surface of the workpiece, thereby positioning the workpiece in the vertical direction. At this time, the lifting spring 33 is in a compressed state.

[0061] In addition, the present invention can change the position of the control screw 342 at the lower end of the positioning end 4 by turning the control screw 342, thereby changing the contact area between the lower surface of the positioning end 4 and the upper surface of the workpiece.

[0062] In summary, the above technical solutions can not only be used for lateral positioning of workpieces, but also for lateral positioning and upper surface positioning of workpieces. Furthermore, the above technical solutions can also be used for lateral positioning or lateral positioning and upper surface positioning of convex structure workpieces, making them widely applicable.

[0063] Example 2:

[0064] Based on Embodiment 1, the present invention modifies the positioning end 4 to enable the present invention to perform lateral positioning or lateral positioning and workpiece upper surface positioning for rectangular workpieces, square workpieces and cylindrical workpieces.

[0065] For details, please refer to Figure 6-7The positioning end 4 has an arc-shaped surface 41 at one end away from the positioning frame 23. A through hole 42 is provided in the middle of the positioning end 4 along the direction of movement of the positioning frame 23, and a strip-shaped positioning block 43 is slidably disposed in the through hole 42. The side of the strip-shaped positioning block 43 facing the arc-shaped surface 41 is a vertical plane structure, so that the present invention can perform lateral positioning of the workpiece with a vertical side through the vertical plane of the strip positioning. The positioning end 4 is provided with a locking component 44 for fixing the strip-shaped positioning block 43.

[0066] See Figure 7-8 Specifically, the locking assembly 44 includes threaded holes on both sides of the positioning end 4, and a locking bolt 441 is threaded into the threaded hole. The strip-shaped positioning block 43 has a locking insertion hole 442 on the side wall facing the threaded hole, which is engaged with the locking bolt 441. By tightening the locking bolt 441, one end of the locking bolt 441 is inserted into the locking insertion hole 442, thereby restricting the sliding of the strip-shaped positioning block 43 in the through hole 42. This ensures that the vertical plane of the strip-shaped limiting hole 5885 on one side of the arc surface 41 can abut against the side of the workpiece to be positioned, thereby realizing lateral positioning or lateral positioning and upper surface positioning of square and polygonal workpieces, and improving the applicability of the present invention.

[0067] To ensure that the locking bolt 441 is smoothly inserted into the locking hole 442, the present invention provides a chamfer 443 at one end of the locking bolt 441 facing the strip positioning block 43.

[0068] Continue reading Figure 6-7 The positioning end 4 is located at the arc surface 41 and is provided with arc-shaped positioning parts 5 on both the upper and lower sides of the strip positioning block 43, which are used to perform lateral positioning of the workpiece with the arc surface 41 on the side.

[0069] Specifically, the arc-shaped positioning component 5 includes a positioning strip 51. Several adjusting sliding holes 52 are evenly provided on the positioning end 4 above or below the through hole 42, which slide in cooperation with the positioning strip 51. The end of the positioning strip 51 facing away from the positioning frame 23 is connected to a contact head 53, and an elastic block 54 is provided on the contact head 53. On the one hand, the contact head 53 is prevented from directly contacting the workpiece, and on the other hand, the contact area is increased to prevent the contact head 53 from making line contact with the workpiece.

[0070] An auxiliary plate 55 is connected to one end of the positioning strip 51 facing the positioning frame 23, and an adjusting spring 56 is connected between the auxiliary plate 55 and the positioning end 4 to drive the positioning strip 51 to move away from the positioning frame 23. A limiting mechanism 57 is provided on the positioning end 4 to limit the movement of the positioning strip 51.

[0071] In the specific implementation process, when dealing with workpieces with arc-shaped sides, such as cylindrical workpieces, the locking bolt 441 is turned in the opposite direction to move the locking bolt 441 out of the locking hole 442, so that the strip positioning block 43 can move towards the positioning frame 23 until the strip positioning block 43 moves into the through hole 42; then, the limitation mechanism 57 on the positioning strip 51 is released so that the positioning strip 51 can be driven to move away from the positioning frame 23 under the action of the adjusting spring 56. At this time, the cylindrical workpiece to be processed is aligned with the arc-shaped surface 41 of the positioning end 4 so that the contact heads 53 at the ends of several positioning strips 51 are pressed against the side of the cylindrical workpiece through the elastic block 54. Then, the positioning strip 51 is restricted in the adjusting slide hole 52 by the limitation mechanism 57. At this time, several contact heads 53 form an arc-shaped structure that matches the side of the cylindrical workpiece to be processed, which facilitates the subsequent lateral positioning of it.

[0072] Since both the upper and lower ends of the positioning end 4 are provided with limit mechanisms 57, and they are identical, this invention will be described in detail using the limit mechanism 57 at the upper end of the positioning end 4. For details, please refer to [link to relevant documentation]. Figure 9-11 The limiting mechanism 57 includes a protective shell 571 at the upper end of the positioning end 4. A control shaft 572 is horizontally arranged and rotatably mounted on the protective shell 571 inside the protective shell 571. A plurality of limiting drive members 58 are evenly arranged along the length of the control shaft 572, and the positions of the limiting drive members 58 correspond one-to-one with the positions of the positioning strip 51. The locking of the positioning strip 51 by the limiting drive members 58 is controlled by the forward and reverse rotation of the control shaft 572.

[0073] The limiting drive component 58 includes a drive bar 581, which is slidably disposed on the upper end of the positioning end 4 along the length direction of the positioning bar 51, and the drive bar 581 is located directly above the limiting drive component 58. The end of the drive bar 581 facing away from the positioning frame 23 is connected to a planar rack 582 that is slidably disposed on the positioning end 4. A control gear 583 that meshes with the planar rack 582 is mounted on the control shaft 572. By rotating the control shaft 572, the control gear 583 drives the planar rack 582 to move, thereby realizing the state of the drive bar 581.

[0074] Drive bars 584 are slidably mounted at both ends of drive bar 581 and along the axis of control shaft 572. Drive bars 584 and drive bars 581 are rotatably connected by linkage bar 585. Control grooves 586 are provided on the upper end of positioning end 4 and on both sides of drive bar 581. Control blocks 587 mounted on drive bars 584 are slidably mounted in control grooves 586. Insertion components 588 are provided at the bottom of control blocks 587. Figure 12 (as shown in the image), used to restrict the movement of the positioning bar 51.

[0075] In the specific implementation process, under the rotation of the control shaft 572, when the drive bar 581 moves towards the positioning frame 23, the linkage bar 585 drives the transmission bar 584 to move away from the drive bar 581, thereby driving the control block 587 to move synchronously in the control groove 586, so that the plug-in assembly 588 no longer restricts the movement of the positioning bar 51 in the adjustment slide hole 52; when the drive bar 581 moves away from the positioning frame 23, the transmission bar 584 drives the control block 587 to move towards the drive bar 581, thereby causing the plug-in assembly 588 to restrict the movement of the positioning bar 51 in the adjustment slide hole 52.

[0076] For further details, please refer to [link / reference]. Figure 12-13 The plug-in assembly 588 includes a plug-in cylinder 5881, which is installed at the bottom of the control block 587. The side wall of the adjusting slide hole 52 is provided with a plug-in hole 5882 that slides with the plug-in cylinder 5881. A plug-in rod 5883 is slidably arranged in the plug-in hole 5882 and facing the positioning bar 51. A push spring 5884 is connected between the plug-in rod 5883 and the inner wall of the plug-in cylinder 5881. Several limiting holes 5885 are provided on both sides of the positioning bar 51 to engage with the plug-in rod 5883. The end of the plug-in rod 5883 facing the positioning bar 51 is provided with an inclination angle 5886 to facilitate the insertion of the plug-in rod 5883 into the limiting hole 5885.

[0077] The control block 587 drives the insertion cylinder 5881 to move toward the limiting hole 5885 until the insertion rod 5883 is inserted into the limiting hole 5885. At this time, the movement of the positioning bar 51 is restricted, ensuring that the contact head 53 can effectively position the workpiece on the side.

[0078] Because there is a gap between two adjacent limiting holes 5885, when the insertion rod 5883 is located between two adjacent limiting holes 5885, there is no restriction on the movement of the positioning strip 51. Therefore, the misaligned portions of several limiting holes 5885 on both sides of the positioning strip 51 of this invention (such as...) Figure 14 As shown, when the insertion rod 5883 on one side of the positioning strip 51 cannot be inserted into the corresponding limiting hole 5885, the insertion rod 5883 on the other side of the positioning strip 51 can be inserted into the corresponding limiting hole 5885. This enables the insertion component 588 to restrict the movement of the positioning strip 51 whenever the positioning strip 51 moves to any position within the adjusting sliding hole 52.

[0079] When one side of the insertion rod 5883 is inserted into the limiting hole 5885, in order to avoid the other side of the insertion rod 5883 affecting the positioning strip 51, the present invention provides a stop component 589 at the bottom of the insertion cylinder 5881 to limit the movement of the insertion rod 5883.

[0080] For details, please refer to Figure 12-13The stop assembly 589 includes a U-shaped frame 5891, which is fixed to the lower end of the plug tube 5881. The bottom of the control groove 586 is provided with a stop groove 5892 to facilitate the movement of the U-shaped frame 5891. A stop strip 5893 is slidably arranged inside the U-shaped frame 5891. The upper end of the stop strip 5893 slides through into the plug tube 5881. A stop hole 5894 is provided at the bottom of the plug rod 5883. A guide slope 5895 that abuts against the plug rod 5883 is provided on the top of the stop strip 5893 and on the side facing the plug rod 5883.

[0081] A stop spring 5896 is connected between the bottom of the stop bar 5893 and the bottom of the U-shaped frame 5891. The stop bar 5893 has a through mating hole 5897, and the bottom of the mating hole 5897 facing away from the plug rod 5883 has a mating inclined surface 5898. The stop slide groove 5892 has an abutting rod 5899 on the side facing away from the adjusting slide hole 52, which abuts against the mating inclined surface 5898.

[0082] In the specific implementation process, when the plug tube 5881 drives the plug rod 5883 to move towards the positioning strip 51, if the plug rod 5883 abuts against the positioning strip 51, the plug rod 5883 moves towards the compression push spring 5884 until the plug rod 5883 abuts against the guide slope 5895 at the top of the stop strip 5893, so that the top of the stop strip 5893 can be inserted into the stop hole 5894, thereby restricting the plug rod 5883 within the plug tube 5881;

[0083] When the plug-in cylinder 5881 moves away from the positioning strip 51 to release the restriction on the positioning strip 51, the plug-in cylinder 5881 moves within the plug-in hole 5882 until the mating inclined surface 5898 on the stop strip 5893 abuts against the abutting rod 5899 fixed to the inner wall of the stop groove 5892, so as to drive the stop strip 5893 to move downward and compress the stop spring 5896 until the top of the stop strip 5893 is completely removed from the stop hole 5894, thereby causing the plug-in rod 5883 to move away from the push spring 5884 under the push of the push spring 5884.

[0084] The implementation principle of this invention:

[0085] Step 1: Select the appropriate positioning method according to the shape and specifications of the workpiece to be processed; if it is necessary to not only perform lateral positioning of the workpiece, but also position the upper surface of the workpiece, the control mechanism 34 can be used to realize the automatic positioning of the upper surface of the workpiece by the positioner 2 at the upper end of the lateral positioning frame 1.

[0086] Step 2: If the workpiece has at least one vertical side, the workpiece can be laterally positioned using the strip positioning block 43 of the positioning end 4; if the workpiece has an arc-shaped side, the arc-shaped positioning part 5 needs to be used for lateral positioning.

[0087] Third step: Secondly, the present invention can turn the positioning screw 272 to change the position of the positioning plate 271, thereby changing the travel of the positioning end 4, so that the present invention can be used for lateral positioning of workpieces with convex structures.

[0088] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
