[0002] Currently, existing flange-type ball screws all use a flange plate fixedly mounted on one end of the ball screw housing to connect to the towed mechanism. However, when faced with the towing of various mechanical devices, the flange plate's installation position cannot be adjusted, making the flange plate installation very limited. In order to enable flange-type ball screws to adapt to the towing installation of various devices, it is necessary to improve the existing flange-type ball screws.

[0003] Utility model publication number CN210510187U proposes a flange-adjustable ball screw, comprising a ball screw housing with two flange plates that can be adjusted left and right along the housing surface. The flange plates are screwed to the housing after being moved to a desired position. The outer surface of the ball screw housing is provided with multiple grooves spaced axially, each containing a number of flange locating holes.

[0004] However, the above-mentioned prior art still has the following deficiencies when in use: when the flange-type ball screw is in use, when a flange needs to be added to drive other components to move together, it is necessary to first remove the support at one end of the ball screw so that there is no obstruction at one end of the ball screw, and then the flange to be added is inserted into the outside of the screw sleeve from the advantage of the ball screw having no obstruction. Therefore, the above-mentioned flange-type ball screw has the defect of inconvenient operation of adding or removing flanges.

[0005] To this end, the utility model provides a flange-adjustable ball screw. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flange-adjustable ball screw to solve the problems raised in the above-mentioned background technology. The utility model has the advantage of being more convenient and quick to add or remove flange plates during the use of the flange-type ball screw, and also has the function of two connection specifications, which is convenient for connection with components with different external hole positions.

[0007] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a flange-adjustable ball screw, comprising a screw sleeve, a flange plate and a locking bolt, the outer peripheral wall of the screw sleeve is provided with an axial guide groove, the axial guide groove is provided with threaded connection holes distributed at equal intervals and matched with the locking bolt, a connecting hole is provided on the flange plate, the number of the axial guide grooves is two and is evenly distributed circumferentially relative to the screw sleeve, the inner peripheral wall of the flange plate is fixedly connected to two guide blocks that slide with the two axial guide grooves respectively, the outer peripheral wall of the flange plate is provided with a positioning hole that penetrates the guide block, the flange plate is divided into two semicircular plates by the axis of the positioning hole as a dividing line, and the outer peripheral wall of the screw sleeve is provided with a notch groove that penetrates the axial guide groove.

[0008] Furthermore, the notch groove is perpendicular to the axial guide groove, and a notch groove is provided between two adjacent threaded connection holes.

[0009] Furthermore, the connection holes of the two semicircular plates are symmetrical with respect to the dividing line of the flange plate.

[0010] Furthermore, the middle parts of the two semicircular plates are fixedly connected to limit blocks, and the outer peripheral wall of the screw sleeve is provided with a limit groove that is slidably matched with the limit block.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a flange-adjustable ball screw, comprising a screw sleeve 1, a flange plate 2 and a locking bolt 3. The outer circumferential wall of the screw sleeve 1 is provided with an axial guide groove 11, and the axial guide groove 11 is provided with threaded connection holes 111 distributed at equal intervals and matched with the locking bolt 3. The flange plate 2 is sleeved on the outside of the screw sleeve 1, and a connecting hole 23 is provided on the flange plate 2. The connecting hole 23 is a hole connected to the component to be transmitted. There are two axial guide grooves 11 and they are evenly distributed circumferentially relative to the screw sleeve 1. The inner circumferential wall of the flange plate 2 is fixedly connected with two guide blocks 21 that slide with the two axial guide grooves 11 respectively. When the guide block 21 slides along the axial guide groove 11, the position of the flange plate 2 on the screw sleeve 1 can be adjusted.

[0023] The outer wall of the flange plate 2 is provided with a positioning hole 22 that passes through the guide block 21. This positioning hole 22 is a locking hole. After the locking bolt 3 is passed through the positioning hole 22, it is screwed together with the threaded connection hole 111. At this time, the circumferential position of the flange plate 2 on the screw sleeve 1 is fixed.

[0024] The flange plate 2 is divided into two semicircular plates 201 by the axis of the positioning hole 22. At this time, the guide block 21 in the flange plate 2 is also bisected. The outer peripheral wall of the screw sleeve 1 is provided with a notch groove 12 that penetrates the axial guide groove 11. Preferably, the notch groove 12 is perpendicular to the axial guide groove 11, and a notch groove 12 is provided between two adjacent threaded connection holes 111. The bisected guide block 21 can leave the axial guide groove 11 through the notch groove 12. That is, after removing the locking bolt 3, the two semicircular plates 201 can be slid to the position of the notch groove 12, and then the semicircular plates 201 can be pulled outward along the radial direction of the screw sleeve 1 to separate them from the screw sleeve 1. This has the advantage of being more convenient and quick to add or remove the flange plate 2.

[0025] In this embodiment, the connection holes 23 of the two semicircular plates 201 are symmetrical with respect to the dividing line of the flange plate 2. This arrangement reduces the difficulty of processing, that is, only one type of semicircular plate 201 needs to be processed, and then the semicircular plate 201 can be used in pairs.

[0026] In this embodiment, the middle parts of the two semicircular plates 201 are fixedly connected to the limiting blocks 2011, and the outer wall of the screw sleeve 1 is provided with a limiting groove 13 that slides with the limiting block 2011. The limiting block 2011 and the limiting groove 13 are connected by plugging. This arrangement can improve the smoothness of the movement of the flange plate 2 on the screw sleeve 1.

[0027] In this embodiment, the outer peripheral walls of the two semicircular plates 201 are plugged into and connected to a sub-plate 4, and a second connection hole 41 located outside the semicircular plate 201 is opened on one side of the sub-plate 4. The function of the second connection hole 41 is to connect with other external components with different hole positions. That is to say, when the connection hole 1 23 on the flange plate 2 does not match the mounting hole of the external component that needs to be transmitted, a matching connection can be achieved by adding a sub-plate 4.

[0028] Furthermore, a slot 2012 is formed on the outer wall of the semicircular plate 201. A plug-in plate 42 is welded to one side of the sub-plate 4 and plugs into the slot 2012. When the sub-plate 4 is no longer needed, the plug-in plate 42 can be simply removed from the slot 2012. A clamping bolt 2013 is threaded through one side of the semicircular plate 201, with one end of the clamping bolt 2013 facing one side of the sub-plate 4. The clamping bolt 2013 is used to lock the plug-in plate 42.

[0029] Working principle: During the use of this ball screw, when it is necessary to add transmission action to other components through the screw sleeve 1, select two semicircular plates 201 and then approach them from both sides of the screw sleeve 1 in a symmetrical state. Under the guidance of the notch groove 12, the two semicircular plates 201 are merged into a flange plate 2, and then slide the flange plate 2 to align it with the positioning hole 22 and one of the suitable threaded connection holes 111, and then use the locking bolt 3 to insert it into the positioning hole 22 and then tighten it with the threaded connection hole 111. At this time, the flange plate 2 and the screw sleeve 1 are docked, and then the added flange plate 2 can be connected with other components that need to be transmitted through the connection hole 23 thereon by bolts.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
