Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering and manufacturing technology, specifically a workpiece stand that adapts to the shape of the workpiece. Background Technology

[0002] In the field of machining and manufacturing, the storage and transfer of workpieces is a crucial part of the production process. Traditionally, workpieces are typically placed directly on the workbench or rack, which presents several problems: workpieces are easily damaged by collisions, especially small, precision workpieces; operators need to frequently bend over to pick up and place workpieces, resulting in high labor intensity and low efficiency; and storage space is limited, making it difficult to meet the diverse storage needs of workpieces. Existing technology also has limitations. Most existing workpiece storage racks are fixed structures and cannot be adjusted according to the size and shape of the workpiece. Furthermore, some workpieces require inspection or processing at specific angles, but traditional storage racks cannot meet these needs. In the machining of large workpieces, such as those used on vertical lathes, workpiece support and stability are critical. Traditional support racks cannot provide sufficient flexibility and stability, affecting machining accuracy and safety.

[0003] In the prior art, the patent with authorization announcement number CN210678657U is entitled "A three-dimensional storage rack for workpieces based on machining". However, it cannot change the size of the workpiece stand according to the size of the workpiece to be placed. Therefore, the workpiece size that this workpiece stand can hold is relatively limited and cannot meet a variety of needs. Utility Model Content

[0004] The purpose of this invention is to provide a workpiece stand that adapts to the shape of the workpiece, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a workpiece stand that adapts to the shape of the workpiece, comprising: a support, and a positioning turntable assembly, wherein the positioning turntable assembly further comprises: a plurality of positioning turntables and a plurality of positioning rods, the plurality of positioning turntables being arranged on longitudinal horizontal rods on both sides of the top of the support, the positioning turntables being provided with a plurality of positioning holes, the plurality of positioning holes being distributed in a threaded manner from the center of the positioning turntable to the edge, and the two ends of the positioning rods being able to be inserted into two positioning holes at the same horizontal position.

[0006] Furthermore, the positioning turntable assembly also includes: a rotating shaft and a lifting lug. The lifting lug is detachably fixed to the longitudinal horizontal bars on both sides of the top of the bracket. The lifting lug is equipped with a rotating shaft, which is rotatably connected to the center of the positioning turntable.

[0007] Furthermore, the positioning rod is provided with several positioning rod U-shaped partition plates, and the two ends of the positioning rod U-shaped partition plates are provided with through holes. The positioning rod passes through the through holes, and the positioning rod U-shaped partition plates can translate on the positioning rod and can rotate freely around the positioning rod.

[0008] Furthermore, several U-shaped partition plates are provided on the transverse bottom beam. Each U-shaped partition plate includes a retaining plate and side plates. Two side plates are provided below the retaining plate. The two side plates can hold the U-shaped partition plates on the transverse bottom beam. The U-shaped partition plates can be moved horizontally on the transverse bottom beam.

[0009] Furthermore, the two side plates on the bottom beam U-shaped partition plate can snap the bottom beam U-shaped partition plate onto the positioning rod.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] This invention allows positioning rods to be placed at different positions via several positioning holes on a positioning turntable. The positioning turntable with the positioning rods installed will naturally sag due to gravity, requiring no manual operation. The positioning rods can be positioned at different heights according to the positions of the different positioning holes, thereby positioning the U-shaped partition plates on the positioning rods at different heights. The U-shaped partition plates on the positioning rods and the U-shaped partition plates on the bottom beam can be displaced on the positioning rods and the transverse bottom beam, respectively, thus adapting to workpieces of different sizes. It can be used for draining, evaporating, cleaning, chemical plating, surface treatment, drying, heat treatment, and storage of workpieces of different shapes or sizes. Attached Figure Description

[0018] The purpose of this utility model is to address the shortcomings of existing technologies by providing a workpiece stand that adapts to the shape of the workpiece, specifically achieved through the following technical solution:

[0019] reference Figure 1 , Figure 2This embodiment provides a workpiece stand that adapts to the shape of the workpiece, including: a support 100, which is a common square support structure and serves to support the entire workpiece stand; and a positioning turntable assembly 200, which further includes: a plurality of positioning turntables 210 and a plurality of positioning rods 230. The plurality of positioning turntables 210 are arranged on longitudinal horizontal rods on both sides of the top of the support 100. The positioning turntable assembly 200 also includes: a rotating shaft 211 and a lifting lug 220, wherein the lifting lug 220 is detachably fixed to the support 100. On the longitudinal horizontal bars on both sides of the top, the lifting lugs 220 can be fixed to the longitudinal horizontal bars on both sides of the top of the bracket 100 with bolts to achieve the purpose of detachment. Several mounting holes can be pre-set on the longitudinal horizontal bars on both sides of the top of the bracket 100 to accommodate the lifting lugs 220 in different positions. The position of the lifting lugs 220 can be changed by changing the position of the positioning turntable 210 connected to it. The lifting lugs 220 are provided with a rotating shaft 211, which is rotatably connected to the center of the positioning turntable 210, so that the positioning turntable 210 can rotate. The positioning turntable 210 is provided with a plurality of positioning holes 212, which are arranged in a spiral pattern from the center of the positioning turntable 210 to the edge. Because the positioning holes 212 are arranged in a spiral pattern, the distance of each positioning hole 212 from the center of the positioning turntable 210 is not the same. This design allows for the arrangement of as many positioning holes 212 as possible within a limited area, making the difference in distance between adjacent positioning holes and the center of the positioning turntable 210 very small. If the positioning holes 212 are arranged on the same straight line passing through the positioning turntable 210, the minimum distance between adjacent positioning holes 212 and the center of the positioning turntable 210 is also the diameter of a positioning hole. Therefore, the spirally distributed positioning holes 212... 2. Within a limited range, the maximum number of positioning holes 212 can be obtained under the premise that the distances of several positioning holes 212 from the center are different. The spiral distribution also has the advantage of making it easy to observe the distance of the required mounting hole 212 from the center manually. If several positioning holes 212 are irregularly distributed on different straight lines, it is theoretically possible to obtain multiple distances from the center. However, the subtle differences in distance between positioning holes 212 are difficult to determine with the human eye, which increases the manual usage cost. With the spiral distribution of positioning holes 212, it is easy to see with the naked eye which positioning hole 212 is longer or shorter from the center, which greatly reduces the learning cost of use.Utilizing the characteristic that different positioning holes 212 are at different distances from the center of the positioning turntable 210, the two ends of the positioning rod 230 are inserted into two positioning holes 212 at the same horizontal position. This results in different distances between the positioning rod 230 and the line connecting the centers of the two positioning turntables 210. This allows control over the positions of several positioning rod U-shaped partition plates 231 set on the positioning rod 230 to accommodate workpieces of different sizes. Furthermore, because the positioning turntable 210 can rotate freely, it will automatically rotate to the corresponding position under gravity after the positioning rod 230 is placed, eliminating the need for manual operation and reducing operating costs. The two positioning turntables 210 set on the same longitudinal top beam can be placed in a mirror image or in the same direction to adapt to different needs.

[0020] Reference Figure 2 The positioning rod 230 is provided with a positioning rod U-shaped partition plate 231 with through holes at both ends. The positioning rod 230 passes through the through holes and the positioning rod U-shaped partition plate 231 can be translated on the positioning rod 230, which can change the distance between two adjacent positioning rod U-shaped partition plates 231, making it easy to adapt to workpieces of different sizes. It can also rotate freely around the positioning rod 230, making it convenient to open, place or pick up workpieces.

[0021] Reference Figure 3 A number of U-shaped partition plates 310 are provided on the transverse bottom beam 300. Each U-shaped partition plate 310 includes a clamping plate 3101 and a side plate 3102. Two side plates 3102 are provided below the clamping plate 3101. The two side plates 3102 can clamp the U-shaped partition plates 310 onto the transverse bottom beam 300. The side plates 3102 are longer than the vertical height of the cross section of the transverse bottom beam 300. Therefore, the side plates 3102 can stably place the U-shaped partition plates 310 onto the transverse bottom beam 300. The U-shaped partition plates 310 can be moved horizontally on the transverse bottom beam 300 to accommodate workpieces of different sizes.

[0022] Reference Figure 3 The two side plates 3102 on the bottom beam U-shaped partition plate 310 can be snapped onto the positioning rod 230. That is, instead of using the positioning rod U-shaped partition plate 231, the bottom beam U-shaped partition plate 310 is placed on the positioning rod 230, which can reduce the overall manufacturing cost of the tooling. However, the tightness of the workpiece placement is lower than that when using the positioning rod U-shaped partition plate 231.

[0023] Example: First, based on the required number and size of the workpieces, select the appropriate number of bottom beam U-shaped partition plates 310 to place on the bottom beam 300. Then, select the appropriate number of positioning rod U-shaped partition plates 231 to place on the positioning rods 230. Place both ends of the positioning rods 230 with the positioning rod U-shaped partition plates 231 in the positioning holes 212 at the required height. If necessary, install the other side in the same way. The preparation work is now complete. Place the workpieces to be placed on the transverse bottom beam 300, reserving one bottom beam U-shaped partition plate 310 on the side closest to the transverse bottom beam 300. After placement, move the bottom beam U-shaped partition plate 310 on the other side and clamp it. The operation at the lower and upper ends of the workpiece is similar. A bottom beam U-shaped partition plate 310 is reserved on one side near the end of the positioning rod 230. After the lower end of the workpiece is placed, the two positioning rod U-shaped partition plates 231 on both sides of the upper end of the workpiece are clamped together to fix one workpiece. Subsequent workpieces can be placed in this way. If the upper and lower ends of the workpiece are the same size, one positioning rod U-shaped partition plate 231 is used at the upper end and one bottom beam U-shaped partition plate 310 is used at the lower end to fix the two workpieces. If the upper and lower ends of the workpiece are different sizes, such as the upper end being thicker or the lower end being thicker, multiple positioning rod U-shaped partition plates 231 or multiple bottom beam U-shaped partition plates 310 of different widths can be used to fix the workpiece as needed.
