Description

Technical Field

[0001] This utility model relates to the field of metal cutting and machining, and in particular to a dual-station rotary table for horizontal machining. Background Technology

[0002] Dual-station rotary tables are one of the most commonly used worktables in the laser cutting field. They are work platforms that achieve orderly switching between two stations through rotation. They are generally divided into loading / unloading stations and processing stations, which can significantly improve work efficiency.

[0003] Chinese Patent No. CN208592587U discloses a dual-station rotary switching device, including a base, a worktable, and a drive mechanism for driving the worktable to rotate around the base. The worktable is a frame-shaped platform formed by welding steel plates, and the top of the worktable is used to fix the product.

[0004] In actual work, during loading and unloading, improper human or mechanical unloading may cause products to fall heavily. The force generated by the downward trend of the products may cause the worktable at the loading and unloading station to suddenly sink or momentarily tilt upward, thus affecting the products being processed. Therefore, it is essential to prevent the worktable at the loading and unloading station from momentarily sinking due to the falling of heavy objects. Utility Model Content

[0005] This invention addresses the problem that a worktable can sink due to a sudden drop during product loading, causing the product at the processing station to momentarily tilt upwards and affecting processing accuracy. It provides a horizontal dual-station rotary worktable that can avoid unstable fluctuations of the worktable caused by a sudden drop during product loading, thereby ensuring the processing accuracy of the product at the processing station.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A horizontal machining dual-station rotary table includes a support base and a table body that rotates horizontally on it. The support base is provided with a drive device that drives the table body to intermittently reciprocate 180° between the loading / unloading station and the machining station. Below the table body at the loading / unloading station, a rotating support mechanism is provided to ensure that the table body is in a horizontal state. The rotating support mechanism includes a column that is vertically fixed on a horizontal reference object and a rolling element that is rolled on the upper end face of the column and rolls against the lower surface of the table body.

[0008] By adopting the above solution, a rotating support mechanism that cooperates with the rolling support at the lower end of the worktable body is set at the loading and unloading station. This ensures that the worktable at the processing station remains horizontal. When a product accidentally falls during the loading process, the worktable will not sink due to the support of the rotating support structure. This ensures that the worktable at the processing station always remains horizontal, thus guaranteeing the processing accuracy of the product being processed.

[0009] Preferably, the workbench body includes an installation platform and symmetrical horizontal support arm assemblies protruding from both sides of the installation platform for assembling fixtures. The support arm assembly includes at least two parallel support arms. A rotating support mechanism is set at the loading and unloading station and corresponds one-to-one with the support arm on one side of the installation platform. A cooperating structure is provided between the support arm and the rotating support mechanism to ensure that the support arm on one side is always at the same height and the fluctuation trend is consistent.

[0010] Using the above solution, the support arm assembly can significantly reduce material usage and lower costs compared to the original tabletop workbench. However, the support arm assembly needs to ensure that all support arms on one side always maintain the same height in order to avoid increased stress caused by height differences in products installed on two or more support arms at the same time.

[0011] Preferably, the mating structure includes mating pads fixed to the lower end of the support arm. The mating pads are provided with guide slopes on both sides along the rotation direction of the workbench body. Two rolling elements are spaced apart on each set of columns along the length of the support arm. The mating pads on one side of the support arm of the mounting platform are rolled and supported by the rolling elements away from the mounting platform, and the mating pads on the other side of the support arm are rolled and supported by the rolling elements close to the mounting platform. The height of the bottom surface of the mating pads at the lower end of adjacent support arms in each set of support arm assemblies increases with the rotation direction of the workbench body.

[0012] Using the above scheme, the mating blocks on the same side need to have a height difference, and the block in front of the rotation direction needs to be slightly higher so that it can pass over the first set of rolling support structures and form rolling support with the rear block at the same time with a set of rolling support structures, ensuring that they are in a synchronous lifting trend, so as to ensure that the product above the support arm is never affected by external forces.

[0013] Preferably, the rolling element is a swivel ball, and a first height adjustment structure is provided between the fixed housing of the swivel ball and the upper end of the column to adjust the height of the swivel ball.

[0014] Using the above scheme, the first height adjustment structure is used to fine-tune the rolling elements, eliminate installation errors of the rolling elements, and can also adapt to support arms of different heights, increasing adaptability.

[0015] Preferably, the column includes a fixed column, a mounting plate located at the upper end of the fixed column, and a second height adjustment structure that limits the vertical lifting and lowering of the mounting plate on the fixed column.

[0016] Using the above scheme, the second height adjustment structure can simultaneously raise and lower the two rolling elements above, which can be used to adapt to support arms of different heights and increase adaptability.

[0017] As a preferred option, the first height adjustment structure is the same as the second height adjustment structure, both of which are achieved by the cooperation of bolts and nuts.

[0018] Preferably, the support base includes a base plate and a support adjustment plate located above the base plate. Anchor bolts for adjusting the levelness of the support adjustment plate are provided at the four corners or four sides of the support adjustment plate and the base plate. Fixing nuts that are screwed to the anchor bolts are fixed on the support adjustment plate. A positioning groove is provided at the upper end of the base plate for the bottom of the anchor bolts to be inserted.

[0019] Using the above solution, the level of the support adjustment plate can be adjusted by anchor bolts, thereby ensuring the levelness of the workbench body.

[0020] Preferably, the four sides of the support adjustment plate are provided with a reinforcing structure to prevent it from deflecting as the worktable body rotates.

[0021] As a preferred embodiment, the reinforcement structure includes an "L"-shaped fixing block, the horizontal and vertical sections of which are screwed to the base plate and the support adjustment plate respectively by fixing bolts, and the vertical section is provided with a vertical waist-shaped groove through which the fixing bolts can pass and be vertically adjusted.

[0022] Using the above solution, the workbench body will generate a large torque when it rotates, and the processing structure can prevent the support adjustment plate from deflecting relative to the base plate product.

[0023] As a preferred option, the upper surface of the installation platform is provided with a "T"-shaped machining surface, and a level is installed on the "T"-shaped machining surface.

[0024] Using the above scheme, the level can measure the levelness of the workbench body, and the "T"-shaped machined surface can ensure the levelness of the level when it is installed.

[0025] This utility model, by adopting the above technical solution, has significant technical effects:

[0026] 1. A rotating support mechanism that cooperates with the rolling support at the lower end of the worktable body is set at the loading and unloading station. This ensures that the worktable at the processing station remains horizontal. When a product accidentally falls during the loading process, the worktable will not sink due to the support of the rotating support structure. This ensures that the worktable at the processing station always remains horizontal and guarantees the processing accuracy of the product being processed.

[0027] 2. The workbench body adopts a combination of mounting platform and support arm, which significantly reduces material usage and achieves lightweighting. At the same time, the rotating support mechanism is set with a corresponding number of groups, and mating pads are installed at the lower end of the support arm. By adjusting the height of the mating pads and the height of the rolling elements, it is ensured that the support arm on one side always maintains the same height and the same lifting trend, so as to ensure that the product installed on the support arm on one side will not experience increased stress due to the height difference of the support arm.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0035] A horizontal machining dual-station rotary table, combined with Figures 1-5 As shown, it includes a support base 1 and a worktable body 3 that rotates horizontally on it. The support base 1 is equipped with a drive device that drives the worktable body 3 to intermittently reciprocate between the loading / unloading station and the processing station at 180°.

[0036] The support base 1 includes a base plate 101 and a support adjustment plate 102 located above the base plate 101. Anchor bolts 12 for adjusting the level of the support adjustment plate 102 are provided at the four corners of the support adjustment plate 102 and the base plate 101. Fixing nuts 1310 that are screwed to the anchor bolts 12 are fixed on the support adjustment plate 102. The upper end of the base plate 101 is provided with a positioning groove for the bottom of the anchor bolts 12 to be inserted. The four sides of the support adjustment plate 102 are provided with a reinforcement structure to prevent it from deflecting as the workbench body 3 rotates. The reinforcement structure includes an "L"-shaped fixing block 14. The horizontal section 142 and the vertical section 141 of the fixing block 14 are screwed to the base plate 101 and the support adjustment plate 102 respectively by fixing bolts 15. The vertical section 141 is provided with a vertical waist-shaped groove 16 through which the fixing bolts 15 can pass and be vertically adjusted.

[0037] The driving device is a servo rotary indexing table, including an indexing table 201 and a servo motor 202. The indexing table 201 is fixed at the upper center of the support adjustment plate 102, the worktable body 3 rotates on the upper surface of the indexing table 201, and the servo motor 202 is installed on the side of the indexing table 201.

[0038] The workbench body 3 includes an installation platform 301 and symmetrical horizontal support arm assemblies protruding from both sides of the installation platform 301 for assembling fixtures. The support arm assembly includes two parallel support arms 302. A rotating support mechanism is provided below the workbench body 3 at the loading and unloading station to ensure that the workbench body 3 is in a horizontal state. The rotating support mechanism is provided in two sets and can correspond one-to-one with the support arm 302 on one side of the installation platform 301. A matching structure is provided between the support arm 302 and the rotating support mechanism to ensure that the support arm 302 on one side is always at the same height and has the same fluctuation trend.

[0039] The rotating support mechanism includes a vertical column fixed to the ground. The column includes a fixed column 5 and a mounting plate 6 located at the upper end of the fixed column 5. A rolling element, which is a universal ball 7, is fixed at the upper end of the mounting plate 6. A mating pad 4 is fixed below the end of the support arm 302 away from the mounting platform 301. The mating pad 4 is provided with guide slopes 401 on both sides along the rotation direction of the workbench body 3. Two universal balls 7 are spaced apart along the length direction of the support arm 302 on each column. The mating pad 4 on one side of the support arm 302 of the mounting platform 301 rolls and cooperates with the universal ball 7 away from the mounting platform 301, and the mating pad 4 on the other side of the support arm 302 rolls and cooperates with the universal ball 7 close to the mounting platform 301. The height of the lower bottom surface of the mating pad 4 at the lower end of the adjacent support arm 302 in each support arm assembly increases with the rotation direction of the workbench body 3.

[0040] A first height adjustment structure for adjusting a single omnidirectional ball 7 is provided between the fixed housing 8 of the omnidirectional ball 7 and the mounting plate 6. A second height adjustment structure for adjusting the vertical height of the mounting plate 6 is provided between the mounting plate 6 and the fixed post 5. The first and second height adjustment structures are identical, both achieving adjustment and limiting through the cooperation of bolts 9 and nuts 10. A bolt 9 is vertically fixed at the bottom of the fixed housing 8 of the omnidirectional ball 7. After the bolt 9 passes through the threaded hole of the mounting plate 6, it is prevented from deflecting through the two nuts 10 above and below. The cooperation between the mounting plate 6 and the fixed post 5 is as follows: Figure 2 The arrangement of the omnidirectional ball 7 and the mounting plate 6 will not be elaborated here. Through the first height adjustment structure and the second height adjustment structure, it is possible to adapt to support arms 302 of different heights, increase adaptability, and also eliminate assembly errors.

[0041] The upper surface of the mounting platform 301 is provided with a "T"-shaped machining surface 11, on which a level (not shown) is mounted.
