[0032] To address the existing technical problem of unstable contact between the auxiliary support device and the machining section, which affects machining accuracy, this invention provides an auxiliary support device and a double-sided boring machine. This auxiliary support device ensures consistent positioning of the wedge, preventing instability or movement of the wedge, thereby guaranteeing the machining accuracy of the double-sided boring machine.

[0033] Please see Figures 1 to 11 This utility model provides an auxiliary support device, which includes a support platform 100, wedges 200, a first fastener 300, and a second fastener 400. The support platform 100 is fixedly installed on the bed 10 of a double-sided boring machine, either integrally welded or detachably installed on the bed 10. The support platform 100 has opposing first inclined surfaces 101. The first direction is defined as the feed direction of the machining section 20, i.e., the X-axis. Specifically, the first inclined surface 101 is located at the top of the support platform 100, extending from one end of the support platform 100 to the other along the feed direction of the machining section 20, and the first inclined surfaces 101 on both sides form a flared structure. The wedges 200 are oppositely arranged on both sides of the support platform 100, and each wedge 200 has a second inclined surface 201 that is adapted to the first inclined surface 101. The wedges 200 on both sides and the top of the support platform 100 together form a guide groove 800. The guide groove 800 guides the machining part 20 during its feed movement on the auxiliary support device. The machining part 20 is provided with a guide seat 21 adapted to the guide groove 800, and the guide seat 21 is slidably connected to the guide groove 800. The first inclined surface 101 and the second inclined surface 201 are in contact. When the wedge 200 moves along the first direction, the distance between the wedges 200 on both sides increases or decreases, that is, the width distance of the guide groove 800 increases or decreases, thereby adjusting the fitting clearance between the guide groove 800 and the guide seat 21. The first fastener 300 is a locking and fixing component. The first fastener 300 fixes the wedge 200 and the support platform 100 along the first direction to restrict the displacement movement of the wedge 200 relative to the support platform 100. The type of the first fastener 300 is not limited, as long as it can meet the displacement movement of the wedge 200 and the locking and fixing with the support platform 100 after the displacement movement. For example, the first fastener 300 can be a screw and nut locking structure, a ball screw structure, or a linear guide structure, but is not limited thereto. The second fastener 400 is fixedly connected to the wedge 200 and the support platform 100 along the second direction, and the second fastener 400 limits the wedge 200 in a direction other than the first direction. Through double or multiple limiting, the problem of the wedge 200 wobbling due to the restricted locking of the first fastener 300 and the feeding movement of the guide seat 21 is avoided. The first direction and the second direction are perpendicular to each other. The second direction can be any direction perpendicular to the first direction, such as the Y-axis or the Z-axis, but is not limited thereto. Specifically, in this embodiment, the second direction is the Y-axis, that is, the width direction of the guide groove 800.

[0034] This auxiliary support device provides additional support for the machining section 20, reducing vibration and displacement during machining and ensuring its stability at different machining stations, thereby improving the machining accuracy of the double-sided boring machine. The wedge 200 moves along the extension direction of the inclined plane, adjusting the distance between the two inclined bodies to adjust and control the fit clearance between the auxiliary support device and the machining section 20. The wedge is locked in place along the first direction by the first fastener 300. Simultaneously, the second fastener 400 locks the wedge 200 in the second direction, ensuring consistent positioning of the wedge 200 and preventing instability or movement, thus guaranteeing the machining accuracy of the double-sided boring machine.

[0035] Please see Figure 3 , Figure 7 and Figure 8 In one embodiment of the auxiliary support device of this utility model, the second fastener 400 includes a second locking part 410, a second oblong hole 420, and a second threaded hole 430. The second locking part 410 is a bolt or screw. The second oblong hole 420 is disposed on the support platform 100. Specifically, the support platform 100 includes a main body 110 and a positioning platform 120. The positioning platform 120 and the main body 110 are integrally formed, and two sets of positioning platforms 120 are located on both sides of the top of the main body 110. The inwardly facing sides of the two sets of positioning platforms 120 are first inclined surfaces 101. The second oblong hole 420 is provided on the positioning platform 120. The second oblong hole 420 penetrates the positioning platform 120 along a second direction, and the length direction of the second oblong hole 420 is consistent with the first direction, so as to accommodate the displacement adjustment of the wedge 200. The second threaded hole 430 is correspondingly provided on the wedge 200, and the second locking part 410 passes through the second waist-shaped hole 420 and is threaded to the second threaded hole 430 to realize the locking and fixing of the wedge 200 and the support table 100 along the second direction.

[0036] Please see Figure 2 and Figure 3 In one embodiment of the auxiliary support device of this utility model, there are multiple sets of second fasteners 400, which are spaced apart along the first direction. By setting multiple sets of second fasteners 400, the locking stability between the wedge 200 and the support platform 100 is ensured, reducing the problem of the wedge 200 shaking and causing the guide seat 21 to jam. Specifically, in this embodiment, there are three sets of second fasteners 400.

[0037] Please see Figure 11In one embodiment of the auxiliary support device of this utility model, the first fastener 300 includes a first locking part 310, a first oblong hole 320, a first nut 330, and a second nut 340. The first oblong hole 320 is disposed on the wedge 200. The first locking part 310 is a screw, and one end of the first locking part 310 passes through the first oblong hole 320 and is fixedly connected to the support platform 100. The first locking part 310 and the support platform 100 can be connected by threads or by welding. The first nut 330 and the second nut 340 are located on both sides of the first oblong hole 320 and are threadedly connected to the first locking part 310. By adjusting the position of the first nut 330 and the second nut 340 on the first locking part 310, the displacement movement and locking fixation of the wedge 200 can be achieved.

[0038] Please see Figure 2 and Figure 11 In one embodiment of the auxiliary support device of this utility model, the auxiliary support device further includes a pressure plate 500, which is located on the upper part of the wedge 200 and is detachably and fixedly connected to the support platform 100. Specifically, in this embodiment, the pressure plate 500 is disposed on the top of the positioning platform 120 and is detachably and fixedly connected to the positioning platform 120 to achieve stable fixation of the guide seat 21 and reduce the vibration impact of the processing part 20.

[0039] Please see Figure 8 and Figure 11 In one embodiment of the auxiliary support device of this utility model, the auxiliary support device further includes a panel 600, which is disposed on the side of the wedge 200 opposite to the second inclined surface 201. Specifically, the panel 600 can be connected to the side of the wedge 200 opposite to the second inclined surface 201 by adhesive or bolt. The panel 600 is clearance-fitted with the guide seat 21. When the guide seat 21 moves forward, the panel 600 is worn first, rather than the wedge 200. Furthermore, the panel 600 can be disassembled and replaced, further reducing damage to the wedge 200 and lowering costs.

[0040] Please see Figure 8 and Figure 11 In one embodiment of the auxiliary support device of this utility model, an oil guide port 210 is provided on the wedge 200, and an oil guide groove 610 is provided on the side of the panel 600 away from the wedge 200. The oil guide port 210 is connected to the oil guide groove 610. The oil guide groove 610 is a semi-open groove structure. Lubricating oil is injected into the oil guide groove 610 through the oil guide port 210. When the guide seat 21 slides in the guide groove 800, an oil film can be formed between the panel 600 and the guide seat 21, reducing the wear between the guide seat 21 and the auxiliary support device.

[0041] Please see Figure 1 and Figure 10In one embodiment of the auxiliary support device of this utility model, the support platform 100 is detachably and fixedly connected to the bed 10 of the double-sided boring machine via an adjustment mechanism 700. The detachable connection between the support platform 100 and the bed 10 allows for adaptive adjustment of the installation position of the auxiliary support device. Removing the support platform 100 can also increase the stroke of the machining section 20, meeting the machining requirements of different workpieces.

[0042] Please see Figure 10 In one embodiment of the auxiliary support device of this utility model, the adjustment mechanism 700 includes a third locking part 710 and a fourth locking part 720. The third locking part 710 is threadedly connected to the support platform 100, and one end of the third locking part 710 abuts against the bed 10. Specifically, the third locking part 710 includes an end 711 and a threaded part 712. The outer side of the threaded part 712 is threadedly connected to the support platform 100, while the lower end of the threaded part 712 passes through the support platform 100 and abuts against the bed 10. Rotating the end 711 can drive the threaded part 712 to rotate, thereby pushing the support platform 100 up or lowering the support platform 100, realizing the height adjustment of the support platform 100, and thus controlling the fitting clearance between the upper part of the support platform 100 and the guide seat 21. The fourth locking part 720 adopts a long screw. The fourth locking part 720 passes through the support platform 100 and is threadedly connected to the bed 10. After the third locking part 710 completes the height adjustment of the support platform 100, the fourth locking part 720 locks and fixes the support platform 100 to the bed 10. Specifically, in this embodiment, the third locking part 710 has an axially through hole, and the fourth locking part 720 passes through the through hole and is threadedly connected to the bed 10.

[0043] The second aspect of this utility model provides a double-sided boring machine, which includes the auxiliary support device described above. It should be noted that the double-sided boring machine of this utility model may also include conventional structures and system modules of existing double-sided boring machines, such as a hydraulic system, a CNC system, an electrical control system, and a worktable.

[0044] In this utility model, the auxiliary support device and double-sided boring machine provide additional support for the machining section, reducing vibration and displacement during machining and ensuring stability at different machining positions, thereby improving the machining accuracy of the double-sided boring machine. The wedge moves along the extension direction of the inclined plane, adjusting the distance between the two inclined bodies to adjust and control the fit clearance between the auxiliary support device and the machining section. The wedge is locked in place along the first direction by a first fastener. Simultaneously, a second fastener locks the wedge in the second direction, ensuring consistent wedge positioning and preventing instability or movement, thus guaranteeing the machining accuracy of the double-sided boring machine. This improves upon the technical problem of unstable contact between the existing auxiliary support device and the machining section, which affects the machining accuracy of the double-sided boring machine. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance.
