Technical Field
[0001] This utility model relates to the field of auxiliary processing technology for bar stock, and in particular to a bar stock processing support device. Background Technology
[0002] In automatic continuous turning on a lathe, the support structure of the bar stock feeding device directly affects the machining accuracy and equipment stability. Existing support devices typically employ a fixed sleeve structure, whose adjustment mechanism has significant drawbacks: when the outer diameter of the bar stock changes, a sleeve assembly that precisely matches the bar stock size must be replaced. However, the installation and center height adjustment of the sleeve are cumbersome and difficult to precisely position. Because the alignment adjustment between the sleeve and the lathe spindle lacks visual feedback, operators can only indirectly judge the support deviation through abnormal noise during bar stock rotation, leading to an experience-dependent and time-consuming adjustment process. Furthermore, after replacing the sleeve, its concentricity with the spindle needs repeated calibration. If the adjustment accuracy is insufficient, the bar stock is prone to radial runout during high-speed rotation, which not only exacerbates equipment vibration and noise but also causes a decline in surface quality and dimensional deviations. This inefficient adjustment method severely restricts the continuous machining efficiency of multi-specification bars. Especially in small-batch, multi-variety production scenarios, frequent support structure replacement and calibration further amplify the stability risks of the machining system. Therefore, we provide a bar stock machining support device to solve the above problems. Utility Model Content

[0031] like Figure 1 — Figure 7 The example shown.
[0032] A bar stock processing support device includes a base 100, a support assembly 200, a pressing assembly 300, a first lifting adjustment assembly 400, and a second lifting adjustment assembly 500. Specifically, two guide posts 110 are fixedly disposed on the top of the base 100, and a spring 111 is sleeved on each guide post 110. The support assembly 200 is slidably mounted on the guide post 110, and the pressing assembly 300 is slidably mounted on the guide post 110. The pressing assembly 300 is located on the side of the support assembly 200 away from the base 100. The spring 111... The first lifting adjustment component 400 is mounted on the base 100 and abuts against the support component 200 and the pressing component 300 respectively. The first lifting adjustment component 400 is used to drive the support component 200 to move along the guide post 110 toward the pressing component 300. The second lifting adjustment component 500 is disposed on the plane formed by the two guide posts 110 and is fixedly connected to the guide post 110. The second lifting adjustment component 500 is used to drive the pressing component 300 to move along the guide post 110 toward the support component 200.
[0033] See Figure 1 and Figure 2 As shown, the bar stock is first positioned in the gap between the support assembly 200 and the pressing assembly 300. When the bar stock needs to be adjusted for support, the first lifting adjustment assembly 400 moves the support assembly 200 upward along the guide post 110, bringing the support assembly 200 to the center height of the lathe spindle. This allows the support assembly 200 to abut against the lower half of the outer circumference of the bar stock, thus limiting the lower half of the bar stock. Further, the second lifting adjustment assembly 500 moves the pressing assembly 300 towards the support assembly 200, bringing the pressing assembly 300 against the upper half of the outer circumference of the bar stock, thereby limiting the upper half of the bar stock. It can be understood that with the limiting effect achieved by the support assembly 200 and the pressing assembly 300 abutting against the bar stock, the occurrence of runout during high-speed rotation of the bar stock is reduced, thereby improving the concentricity of the bar stock and the lathe spindle, and improving the machining accuracy of the bar stock.
[0034] The support assembly 200 includes a sliding plate 210 slidably mounted on the guide post 110. The sliding plate 210 is provided with multiple sets of rolling support members, each set of rolling support members including two support wheels 220.
[0035] See Figure 2 and Figure 3As shown, to prevent the bar stock from undergoing hard friction with the sliding plate 210 during rotation, multiple sets of rolling supports are provided on the sliding plate 210, with two support components 200 forming a group. Specifically, the two support wheels 220 are arranged side by side, with a certain distance between them to accommodate bars of different diameters. Furthermore, the bar stock is located between the two support wheels 220 of each set of rolling supports, and the outer circumferential surface of the support wheel 220 abuts against the outer circumferential surface of the bar stock, thereby supporting the bar stock. It can be understood that the bar stock abuts against the two support wheels 220, and the support wheels 220 can rotate. The rotation of the bar stock drives the rotation of the support wheels 220, thereby converting hard friction into rolling friction, thus reducing friction and preventing damage to the sliding plate 210 and the bar stock itself due to excessive friction.
[0036] In this embodiment, multiple sets of rolling support members can be provided on the sliding plate 210. When the number of rolling support members is greater than or equal to 2, the two adjacent rolling support members are spaced apart, and the two support wheels 220 located at the same position are coaxially arranged. When supporting the bar stock, it can maintain a high degree of coaxiality.
[0037] Multiple spacing adjustment components 230 are provided on the sliding plate 210. The spacing adjustment components 230 are used to adjust the spacing between the two support wheels 220. The spacing adjustment components 230 include side plates 231 fixedly installed on the sliding plate 210, a guide shaft 232 installed between the two side plates 231, and two sliders 233 slidably installed on the guide shaft 232. The sliding plate 210 is provided with a guide groove 2331. The sliders 233 are slidably connected to the guide groove 2331. The support wheels 220 are rotatably installed on their corresponding sliders 233. Each side plate 231 is connected with an adjusting bolt 234 extending to the position of the slider 233. An adjusting nut 235 is installed on the adjusting bolt 234. An elastic element is provided between the slider 233 and the side plate 231.
[0038] Please continue reading. Figure 2 and Figure 3 As shown, in order to support bars of different diameters, it is necessary to change the distance between the two support wheels 220 of the same rolling support, so that it can support bars of different diameters and make the bars coaxial with the lathe spindle. Furthermore, the adjusting bolt 234 is threadedly connected to the side plate 231 and the slider 233 respectively.
[0039] Specifically, when it is necessary to adjust the distance between the two support wheels 220, the adjusting nut 235 can be used to rotate the adjusting bolt 234, thereby moving it away from the side plate 231. Since the adjusting bolt 234 is also threadedly connected to the slider 233, the slider 233 will move in the same direction as the adjusting bolt 234 moves, causing the two sliders 233 to move away from each other, increasing the distance between the two support wheels 220. It can be understood that under the sliding guidance of the slider 233 and the guide groove 2331, the slider 233 will not rotate about the guide shaft 232 during its movement, but will move about the guide trajectory of the guide groove 2331. Similarly, rotating the adjusting bolt 234 in the opposite direction can also cause the slider 233 to move in the same direction, even if the two sliders 233 move closer to each other, reducing the distance between the two support wheels 220.
[0040] In another embodiment, the adjusting bolt 234 is threadedly connected to the side plate 231, and the end of the adjusting bolt 234 abuts against the side wall of the slider 233. A compression spring (not shown) is sleeved on the guide shaft 232, and the compression spring is located between the two sliders 233, that is, the two ends of the compression spring abut against the side walls of the two sliders 233. The adjusting bolt 234 can be rotated by the adjusting nut 235, so that the adjusting bolt 234 moves towards the guide shaft 232, overcoming the elastic force of the compression spring and moving the two sliders 233 closer together, thereby reducing the distance between the two support wheels 220. Similarly, when it is necessary to increase the distance between the two support wheels 220, the adjusting bolt 234 is rotated in the opposite direction by the adjusting nut 235, so that the adjusting bolt 234 moves away from the side plate 231 to a predetermined position. Since there is no longer resistance on one side of the slider 233, the slider 233 moves towards the side plate 231 under the action of the elastic force of the compression spring, thereby increasing the distance between the two support wheels 220, so as to support bars with larger diameters.
[0041] In this embodiment, in order to facilitate the rotation of the adjusting bolt 234 by adjusting the adjusting nut 235, the adjusting nut 235 can be a wing nut for easy use.
[0042] The pressing assembly 300 includes a pressing plate 310 slidably mounted on the guide post 110, and at least one pressing wheel 320 is rotatably mounted on the bottom of the pressing plate 310.
[0043] In order to press down and position the upper part of the bar stock, a pressure plate 310 is slidably installed on the guide post 110. A pressure roller 320 is installed on the side wall of the pressure plate 310. By abutting the outer circumferential surface of the pressure roller 320 with the outer circumferential surface of the bar stock, and positioning it between the two support rollers 220 and the pressure roller 320, the bar stock and the lathe spindle have a high degree of concentricity, thus improving the machining accuracy.
[0044] See Figure 4 As shown, in this embodiment, two pressure rollers 320 are installed on the pressure plate 310, and there is a certain gap between the two pressure rollers 320. The two support rollers 220 and the two pressure rollers 320 work together to fully engage with the outer circumferential surface of the bar stock to achieve positioning.
[0045] The first lifting adjustment component 400 is fixedly installed on the first mounting plate 410 on the base 100. The first mounting plate 410 is threadedly connected to the first lead screw 420. The end of the first lead screw 420 extends and abuts against the support component 200. The end of the first lead screw 420 away from the support component 200 is fixedly installed with the first handwheel 430.
[0046] See Figure 2 As shown, when it is necessary to adjust the height of the support wheel 220 to adapt to the height of the bar stock, the first handwheel 430 can be manually turned to drive the first lead screw 420 to rotate. Since the first lead screw 420 is threadedly connected to the first mounting plate 410, the first lead screw 420 will gradually move towards the support assembly 200 during rotation, thereby driving the support assembly 200 to overcome the elastic force of the spring 111 and move upward, so that the support wheel 220 is raised and comes into contact with the bar stock.
[0047] Understandably, when the support component 200 needs to be lowered, the first handwheel 430 can be used to drive the first lead screw 420 to rotate in the opposite direction. As the first lead screw 420 gradually moves away from the support component 200, under the action of the support component 200's own weight and the elastic force of the spring 111, the support component 200 will move downward along the guide post 110, thereby causing the support wheel 220 to move downward to adjust, so as to meet the height of the bar stock.
[0048] The second lifting adjustment assembly 500 includes a second mounting plate 510 fixedly mounted on the top surface of the guide post 110. A second lead screw 520 is threaded onto the second mounting plate 510. The second lead screw 520 extends and abuts against the pressing assembly 300. A second handwheel 530 is mounted on the end of the second lead screw 520 away from the pressing assembly 300.
[0049] Please continue reading. Figure 2 As shown, in order to enable the pressing wheel 320 in the pressing assembly 300 to abut against the upper half of the outer circumference of the bar stock, the second screw 520 can be rotated by the second handwheel 530 to move towards the support assembly 200. Since the end of the second screw 520 abuts against the pressing plate 310 of the pressing assembly 300 and the second mounting plate 510 is fixedly connected to the top of the guide post 110, when the second screw 520 moves towards the pressing plate 310, it will overcome the elastic force of the spring 111 and drive the pressing plate 310 to move along the guide post 110 towards the support assembly 200, so that the pressing wheel 320 abuts against the upper half of the outer surface of the bar stock.
[0050] Understandably, when it is necessary to move the pressing assembly 300 upward, it is only necessary to drive the second lead screw 520 to rotate in the opposite direction through the second handwheel 530. Since the pressing plate 310 is no longer blocked by the second lead screw 520, it is driven to move upward under the elastic force of the spring 111, so as to meet the needs of different bar diameters.
[0051] In this embodiment, the distance between the support component 200 and the pressing component 300 can be adjusted by the linkage adjustment of the first lifting adjustment component 400 and the second lifting adjustment component 500, thereby adapting to bars of different diameters and having high practicality.
[0052] A protective cover 600 is provided on one side of the support assembly 200 and connected thereto. The protective cover 600 includes a shell 610 connected to the support assembly 200 via a rod. A protective cavity 620 is formed inside the shell 610. A first opening 621 and a second opening 622 are respectively opened at both ends of the protective cavity 620. A cover plate 630 is hinged to the protective cavity 620 and is used to open or close the upper opening of the protective cavity 620.
[0053] See Figure 1 and Figure 2 As shown, in order to prevent the bar stock from being exposed to the outside and potentially causing injury to people around, a protective cover 600 is provided on one side of the support assembly 200. Specifically, the housing 610 has an upper opening and openings on both sides, a first opening 621 and a second opening 622. When installing the bar stock, the upper opening can be opened through the cover plate 630, and then the bar stock passes through the first opening 621, the protective cavity 620 and the second opening 622 to the position of the machine tool spindle. At this time, the end of the bar stock is located in the protective cavity 620. Then, the upper opening of the protective cavity 620 can be closed through the cover plate 630 to prevent the bar stock from being exposed to the outside.
[0054] In this embodiment, the base 100 includes two vertically arranged columns 101, a crossbar 102 is arranged between the two columns 101, a foot 103 is installed at the bottom of each column 101, a side support plate 104 is fixedly installed on the bottom side wall of each column 101, a connecting rod 105 is arranged on one side of the top of the column 101, and a connecting plate 106 is arranged at the end of the connecting rod 105 away from the column 101.
[0055] See Figure 1As shown, a frame is formed by the column 101 and the crossbar 102. In order to improve the stability of the frame, side support plates 104 that are in contact with the ground are fixedly installed on both sides of the bottom of the column 101 to prevent it from shaking. Furthermore, the frame is fixedly connected to the machine tool by the connecting rod 105 at the top of the column 101 and the connecting plate 106 at the end of the connecting rod 105.
[0056] In this embodiment, the length of the connecting rod 105 can be different according to actual needs, and no specific limit is made here.
[0057] See Figure 5 As shown, in order to make the support device adaptable to longer bars, it can be formed by assembling two support devices to provide more stable support for the bars. It is understood that, in the assembled state of the two support devices, the protective cover 600 is set on the support device away from the machine tool.
[0058] See Figure 6 and Figure 7 As shown, Figure 6 The diagram shown is a schematic of a support device used in conjunction with a machine tool. Figure 7 The diagram shows the installation of the machine tool with the two support devices in the working state.
[0059] The working process of this utility model is as follows: When it is necessary to support the bar stock, the upper opening of the protective cavity 620 is first opened through the cover plate 630. Then the bar stock will pass through the gap space formed by the protective cavity 620, the support component 200 and the pressing component 300 until it reaches the position of the machine tool spindle. Next, in order to support the bar stock, the height of the support component 200 can be adjusted by the first lifting adjustment component 400 until the support wheel 220 of the support component 200 abuts against the bar stock. Then the height of the pressing component 300 can be adjusted by the second lifting adjustment component 500 until the pressing wheel 320 of the pressing component 300 abuts against the bar stock. The positioning support of the bar stock is achieved through the cooperation of the support wheel 220 and the pressing wheel 320, so that the bar stock is coaxial with the lathe spindle.
[0060] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
