[0055] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0056] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure of this application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit this application. In addition, this application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0057] For ease of description, spatially relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms such as "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or movement state change, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will then be oriented as "above" or "upper" other elements or features. Therefore, the exemplary term "below" can include the orientations of above and below. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0058] To solve the technical problem of interference between the bracket and the grinding wheel during the grinding process of the workpiece by the machine tool in the prior art, this application provides a follow-up bracket 100 and a machine tool, which can adjust the position of the bracket body 116 to support the workpiece while the grinding point of the workpiece changes, so that the support position and the grinding point are out of position, and avoid interference between the bracket body 116 and tools such as the grinding wheel.

[0059] The connection referred to in this article includes both direct contact connections and indirect connections through other structural components. This article explains the principle that the grinding wheel does not interfere with the bracket body 116 during the grinding of the workpiece by the grinding wheel. In actual implementation, the grinding wheel can also be replaced with other types of cutting tools, that is, the interference between the cutting tool and the bracket body 116 is effectively avoided.

[0060] An embodiment of the present application provides a follow-up bracket 100, as Figures 1 to 3 shown. The follow-up bracket 100 includes a bracket body 116, a guide rail base 102, a guide rail slider 106, and a linear drive mechanism. The bracket body 116 is provided with a support groove, and the support groove can slide relative to the workpiece to achieve the sliding support of the bracket body 116 at different positions of the workpiece. The guide rail base 102 is provided with a sliding guide rail, the guide rail slider 106 is slidably connected to the sliding guide rail, and the bracket body 116 is connected to the guide rail slider 106 and slides under the drive of the guide rail slider 106.

[0061] The linear drive mechanism is fixed to the guide rail base 102 and is used to drive the guide rail slider 106 to slide along the sliding guide rail. The form of the linear drive mechanism is not limited here. A linear motor can be used, or a servo motor can be used in cooperation with a lead screw drive, or a drive cylinder or an oil cylinder can also be used. The follow-up bracket 100 provided by the present application can be installed on a machine tool and slide-support the workpiece. When the machine tool drives the workpiece to move relative to the grinding wheel, that is, when the position of the grinding point changes, it can drive the bracket body 116 to move, so that the support position of the bracket body 116 for the workpiece changes along with the change of the grinding point, effectively avoiding the interference between the grinding wheel and the bracket body 116.

[0062] With reference to Figure 2 and Figure 6 , the above-mentioned follow-up bracket 100 can install and fix the guide rail base 102 on a set of drive parts of the machine tool through the bracket mounting plate 101. Figure 6 The shown machine tool includes a first horizontal moving platform 300, that is, an X-axis moving platform, a second horizontal moving platform 400, that is, a Z-axis moving platform, and a rotating platform 200 (the rotation axis of the rotating platform 200 coincides with the X-axis. For non-national standard machine tools, it is called a C-axis rotating platform, and for national standard machine tools, it is called an A-axis rotating platform), and also includes a lifting moving platform, that is, a Y-axis moving platform, etc. not shown.

[0063] The second horizontal moving platform 400 is connected to the first horizontal moving platform 300, the rotating platform 200 is connected to the second horizontal moving platform 400, the workpiece clamping portion 500 is fixed to the rotating platform 200, and the guide rail base 102 is fixed to the shaft seat of the rotating platform 200 through the bracket mounting plate 101. When machining a workpiece, the position of the grinding wheel, i.e., the tool, remains unchanged. When the first horizontal moving platform 300 drives the workpiece to feed towards the grinding wheel along the first direction, i.e., the X-axis direction, through the second horizontal moving platform 400 and the rotating platform 200, the grinding position of the workpiece changes, and the guide rail base 102 moves synchronously. The linear drive mechanism fixed to the guide rail base 102 drives the guide rail slider 106 to move along the sliding guide rail, and then drives the bracket body 116 connected to the guide rail slider 106. The bracket body 116 slides relative to the workpiece through the support groove, changing the support position of the bracket body 116 on the workpiece, so that the support position of the bracket body 116 on the workpiece and the grinding position of the grinding wheel on the workpiece are out of position, effectively preventing interference between the bracket body 116 and the grinding wheel.

[0064] In some embodiments, the linear drive mechanism may specifically adopt the form of a lead screw motor 103 cooperating with a first lead screw 105. The lead screw motor 103 is fixed to the guide rail base 102 and coaxially connected to the input end of the first lead screw 105. The lead screw nut of the first lead screw 105 is fixedly connected to the guide rail slider 106, and the forward and reverse rotation of the lead screw motor 103 drives the reciprocating movement of the guide rail slider 106 along the sliding guide rail.

[0065] Preferably, in order to reduce the length of the follow-up bracket 100, the lead screw motor 103 and the first lead screw 105 can also be respectively arranged on both sides of the guide rail base 102, and the lead screw motor 103 and the first lead screw 105 are connected through a transmission mechanism 104. Exemplarily, the lead screw motor 103 is fixed to the first side surface of the guide rail base 102, the first lead screw 105 is arranged on the second side surface of the guide rail base 102, the first side surface and the second side surface are located on both sides of the guide rail base 102 that are opposite to each other, and the sliding guide rail and the guide rail slider 106 are both arranged on the second side surface of the guide rail base 102. The lead screw motor 103 and the first lead screw 105 are connected through a transmission mechanism 104, and the transmission mechanism 104 can be a set of gear reducers. The input end of the gear reducer is connected to the output shaft of the lead screw motor 103, and the output end of the gear reducer is connected to the input end of the first lead screw 105. By setting the decelerating transmission mechanism 104, not only can the length of the follow-up bracket 100 be reduced, facilitating the installation of the follow-up bracket 100 on the machine tool, but also the sliding speed of the guide rail slider 106, i.e., the bracket body 116, relative to the workpiece can be precisely controlled.

[0066] In some embodiments, such as Figure 4As shown, the guide rail base 102 includes a first base 1021, a second base 1022 and adjusting set screws. An installation groove is provided on the second side surface of the first base 1021. A plurality of sets of set screw holes 1023 are provided through the side wall of the installation groove, and the plurality of sets of set screw holes 1023 are arranged along the length direction of the installation groove. The second base 1022 is connected to the second side surface of the first base 1021 through the installation groove, and the second base 1022 and the installation groove of the first base 1021 are in clearance fit. The sliding guide rail is installed and fixed on the side of the second base 1022 facing away from the first base 1021. Installation edges 10221 are provided on both sides of the second base 1022 facing the inner wall of the installation groove, that is, on both sides in the width direction. The adjusting set screws are threadedly connected to the set screw holes 1023 and abut against the installation edges 10221. By screwing the adjusting set screws at different set screw holes 1023 to abut and limit the installation edges 10221 of the second base 1022, the levelness of the second base 1022, the sliding guide rail and the bracket body 116 in the first direction (X-axis direction) is adjusted to ensure that the support groove of the sliding guide rail and the bracket body 116 is parallel to the X-axis direction, and the support accuracy for the workpiece is improved.

[0067] With reference to Figure 2 and Figure 5 , on the basis of the above embodiments, the follow-up bracket 100 provided by the embodiment of the present application further includes an adjusting mechanism, and the adjusting mechanism is connected between the guide rail slider 106 and the bracket body 116 to adjust the position of the bracket body 116 relative to the guide rail slider 106. Exemplarily, the adjusting mechanism can be used to adjust the height position of the bracket body 116, and the adjusting mechanism can also be used to adjust the position of the bracket body 116 in the direction perpendicular to the sliding guide rail.

[0068] In some embodiments, the adjusting mechanism at least includes a first lifting plate 109, a first guide shaft 110, a lifting cylinder 108 and a cylinder mounting frame 107. The cylinder mounting frame 107 is fixed to the guide rail slider 106, the lifting cylinder 108 and the first guide shaft 110 are vertically fixed to the cylinder mounting frame 107, the first lifting plate 109 is connected to the first guide shaft 110 in a lifting and sliding manner, and the bracket body 116 is arranged above the first lifting plate 109. The output end of the lifting cylinder 108 can be fixedly connected to the first lifting plate 109 or can be arranged in a non-fixed manner. When the output end of the lifting cylinder 108 is fixedly connected to the first lifting plate 109, the lifting cylinder 108 drives the first lifting plate 109 to lift along the first guide shaft 110 through expansion and contraction. When the output end of the lifting cylinder 108 is not fixed to the first lifting plate 109, the lifting cylinder 108 extends to drive the first lifting plate 109 to rise along the first guide shaft 110, and the lifting cylinder 108 contracts without driving the first lifting plate 109 to descend. Under the action of the gravity or external force of the first lifting plate 109 and the bracket body 116, the first lifting plate 109 descends along the first guide shaft 110.

[0069] To improve the stability of the lifting movement of the first lifting plate 109, multiple groups of first guide shafts 110 can be provided. For example, two groups of first guide shafts 110 are provided, and the two groups of first guide shafts 110 are arranged parallel to each other on both sides of the lifting cylinder 108.

[0070] Furthermore, the adjusting mechanism further includes a second lifting plate 112, a second lead screw 111, a second guide shaft, and a locking mechanism 113. The second lifting plate 112 is arranged parallel to the upper side of the first lifting plate 109, that is, on the side away from the lifting cylinder 108. The second guide shaft is fixed to the second lifting plate 112, and the locking mechanism 113 is fixed to the first lifting plate 109. The first lifting plate 109 and the second lifting plate 112 are connected by the second guide shaft for lifting and sliding. The second guide shaft (not shown in the drawings) passes through the locking mechanism 113 at the same time. The locking mechanism 113 is used to clamp and lock the second guide shaft, thereby fixing the second lifting plate 112 relative to the first lifting plate 109. The locking mechanism 113 is provided with a locking handle 1131. By moving the locking handle 1131 between the locking position and the unlocking position, the locking and unlocking of the second guide shaft are realized. When the second guide shaft is in the unlocked state, it can lift and slide relative to the locking mechanism 113 and the first lifting plate 109, so as to adjust the height position of the second lifting plate 112 and the bracket body 116.

[0071] The second lead screw 111 can adopt a trapezoidal lead screw. The second lead screw 111 is also provided with a lead screw handle 1111. When the locking mechanism 113 unlocks the second guide shaft, by turning the lead screw handle 1111 to drive the trapezoidal lead screw to rotate, the distance between the first lifting plate 109 and the second lifting plate 112 can be adjusted. After the adjustment is in place, the locking handle 1131 is moved again to lock the second guide shaft.

The lateral adjusting seat 114 is fixed above the second lifting plate 112. The upper end surface of the lateral adjusting seat 114 is provided with a lateral adjusting groove. The lateral adjusting guide rod 115 is connected in the lateral adjusting groove. The extending direction of the lateral adjusting guide rod 115 is perpendicular to the extending directions of the sliding guide rail and the first guide shaft 110. The bracket body 116 is slidably connected to the lateral adjusting guide rod 115. The micrometer barrel 117 extends from the outside of the lateral adjusting seat 114 through the side wall of the lateral adjusting groove to the inside of the lateral adjusting groove and is connected to the bracket body 116. By turning the micrometer barrel 117, the lateral position of the bracket body 116 (that is, the position in the Z-axis direction) can be adjusted.

[0073] In some embodiments, the bracket body 116 is slidably connected to the lateral adjustment guide rod 115 through the lateral adjustment slider 118. The micrometer barrel 117 is connected to the lateral adjustment slider 118. By driving the lateral adjustment slider 118 to move along the lateral adjustment guide rod 115, the bracket body 116 is driven to move. The bracket body 116 and the lateral adjustment slider 118 are detachably connected, so that it is convenient to replace the bracket body 116 of different models according to different workpieces.

The second horizontal moving platform 400 is connected to the first horizontal moving platform 300 and reciprocates along the X-axis direction under the drive of the first horizontal moving platform 300. The workpiece clamping portion 500 is connected to the second horizontal moving platform 400 and can reciprocate along the Z-axis direction under the drive of the second horizontal moving platform 400. That is, the lifting and moving platform, the first horizontal moving platform 300, and the second horizontal moving platform 400 can drive the workpiece to move in the corresponding direction. The follow-up bracket 100 is connected to the second horizontal moving platform 400 through the bracket mounting plate 101.

That is, the five-axis machine tool may include two sets of rotating platforms 200 or one set of rotating platforms 200 plus one set of swing driving portions. When the five-axis machine tool includes one set of rotating platforms 200, the rotating platform 200 may be a C-axis rotating platform connected to the second horizontal moving platform 400. The rotation axis of the C-axis rotating platform coincides with the first direction, that is, the X-axis direction (for non-national standard machine tools, it is called a C-axis rotating platform, and for national standard machine tools, the rotating platform 200 is called an A-axis rotating platform).
