Traditional workpiece positioning methods, such as fixed mold positioning and direct gripping by robotic arms, can meet basic production needs in certain specific environments, but their inherent limitations are becoming increasingly apparent, especially during the workpiece packing stage.

[0003] The shortcomings of the existing technology are that, due to process issues, the workpiece needs to be repositioned and corrected after deformation, resulting in low efficiency in positioning the workpiece and affecting subsequent processing steps.

[0004] Therefore, there is a need to provide a workpiece rapid positioning device to solve the problems mentioned above. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a workpiece rapid positioning device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a workpiece rapid positioning device, including a bracket, a base fixedly connected to the bottom end of the bracket, a sliding groove opened in the middle of the top end of the bracket, limit grooves opened on both sides of the inner wall of the sliding groove, limit plates fixedly connected to the top end of the bracket near both sides, a support column movably sleeved on the top end of the base through a bearing, a positioning turntable fixedly connected to the top end of the support column, and a sensor fixedly installed near one side of the bracket;

[0007] The workpiece rapid positioning device includes:

[0008] A movable component is provided at the top of the support, and a crosshair cursor transmitter is fixedly provided at the bottom of the movable end of the movable component. The movable component is used to drive the crosshair cursor transmitter to move.

[0009] A rotating assembly is disposed between the outer wall of the support column and the top of the base, and is used to drive the support column and the positioning turntable to rotate;

[0010] Preferably, the moving component includes:

[0011] A movable motor is mounted on the top of the bracket near the limiting plate. A fixing plate is fixedly connected to the bottom of the movable motor. The right side of the fixing plate is fixedly connected to the bracket. A lead screw is fixedly connected to the transmission end of the movable motor through the limiting plate. The two ends of the lead screw are movably sleeved with the opposite sides of the two limiting plates. A threaded collar is threaded onto the outer wall of the lead screw. A slider is fixedly connected to the bottom end of the threaded collar. The bottom end of the slider is fixedly connected to the crosshair cursor transmitter.

[0012] A limiting mechanism is provided on the outer wall of the slider to limit the movement of the threaded collar.

[0013] Preferably, the limiting mechanism includes a limiting slide rod, the outer walls of both ends of the limiting slide rod are slidably connected to two limiting grooves, and the outer wall of the slider is slidably connected to the slide groove.

[0014] Preferably, three sets of positioning line transmitters are fixedly connected to both sides of the positioning turntable, and a red line cursor is formed between each set of positioning line transmitters.

[0015] Preferably, the rotating component includes:

[0016] A toothed swivel ring, the middle of which is fixedly sleeved with the outer wall of the support column, and two rolling columns are slidably connected to the outer wall of the toothed swivel ring. The middle of each of the two rolling columns is rotatably connected to a limit frame. A vertical plate is fixedly connected to the right side of the two limit frames. The bottom end of the vertical plate is fixedly connected to the top of the base near the right side.

[0017] A drive mechanism is provided on the right side of the outer wall of the toothed ring and is used to drive the toothed ring to rotate.

[0018] Preferably, the driving mechanism includes a gear, the outer wall of the gear meshing with the outer wall of the toothed rotating ring, a support plate movably connected to both the top and bottom ends of the gear, the right sides of the two support plates being fixedly connected to the upright plate, and a rotary motor being fixedly connected to the top end of one support plate, the transmission end of the rotary motor passing through the support plate and being fixedly connected to the gear.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. This utility model, by incorporating a moving component and a crosshair transmitter, allows for the positioning of a workpiece on the top of the positioning turntable. When the workpiece is positioned, the crosshair transmitter is activated, and with the support of a fixed plate, a moving motor is simultaneously activated, driving a lead screw to rotate between two limiting plates. This, in turn, causes a threaded collar to move along the outer wall of the lead screw. The slider at the bottom of the threaded collar slides within a groove, and a limiting slide bar slides within a limiting groove as the slider moves, thus limiting the movement of the threaded collar. This facilitates the movement of the crosshair transmitter under the support of the bracket, ensuring it aligns with one of the positioning lines of the workpiece on the positioning turntable. This allows for the detection of any deviation in other workpieces, enabling adjustments to any misaligned workpieces and improving workpiece positioning efficiency.

[0021] 2. This utility model features a rotating assembly. Supported by a vertical plate and two support plates, the rotating motor is activated, and the gears rotate under the action of the reducer. This, in turn, rotates the meshing toothed rotating ring, thereby rotating the support column and the positioning turntable. Under the action of the sensor, when a red line cursor moves to the direction connecting the 12 o'clock and 6 o'clock positions, the controller shuts off the rotating motor and activates the moving assembly to make the crosshair cursor emitter coincide with any red line cursor. When a red line cursor fails to coincide, the rotating motor is activated again, causing the support column and the positioning turntable to continue rotating until they coincide with the cursor of the crosshair cursor emitter. This facilitates the rapid positioning and correction of misaligned workpieces, making subsequent processing easier. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0030] Example 1

[0031] This utility model is a workpiece rapid positioning device, including a bracket 1, a base 5 fixedly connected to the bottom end of the bracket 1, a sliding groove 101 opened in the middle of the top end of the bracket 1, a limit groove 102 opened on both sides of the inner wall of the sliding groove 101, a limit plate 3 fixedly connected to the top end of the bracket 1 near both sides, a support column 8 movably sleeved on the top end of the base 5 through a bearing, a positioning turntable 4 fixedly connected to the top end of the support column 8, and a sensor fixedly installed near one side of the bracket 1.

[0032] The workpiece rapid positioning device includes:

[0033] The moving component 2 is located at the top of the support 1. A crosshair transmitter 6 is fixedly installed at the bottom of the moving end of the moving component 2. The moving component 2 is used to drive the crosshair transmitter 6 to move.

[0034] Rotating component 7 is disposed between the outer wall of the support column 8 and the top of the base 5, and is used to drive the support column 8 and the positioning turntable 4 to rotate.

[0035] Mobile component 2 includes:

[0036] The mobile motor 202 is located at the top of the bracket 1 near the limiting plate 3. The bottom end of the mobile motor 202 is fixedly connected to the fixing plate 201. The right side of the fixing plate 201 is fixedly connected to the bracket 1. The transmission end of the mobile motor 202 passes through the limiting plate 3 and is fixedly connected to the lead screw 203. The two ends of the lead screw 203 are movably sleeved with the opposite sides of the two limiting plates 3. The outer wall of the lead screw 203 is threaded with a threaded collar 205. The bottom end of the threaded collar 205 is fixedly connected to the slider 204. The bottom end of the slider 204 is fixedly connected to the crosshair cursor transmitter 6.

[0037] A limiting mechanism is provided on the outer wall of the slider 204 to limit the movement of the threaded collar 205.

[0038] The limiting mechanism includes a limiting slide bar 206, the outer walls of both ends of the limiting slide bar 206 are slidably connected in two limiting grooves 102, and the outer wall of the slider 204 is slidably connected in a slide groove 101.

[0039] Three sets of positioning line transmitters 10 are fixedly connected to both sides of the positioning turntable 4, and a red line cursor 9 is formed between the positioning line transmitters 10.

[0040] In this embodiment, as Figure 1-3 and Figure 5 As shown, the workpiece is placed on the positioning turntable 4. When positioning the workpiece on the top of the positioning turntable 4, the crosshair transmitter 6 is turned on. With the support of the fixed plate 201, the moving motor 202 is turned on at the same time, which drives the lead screw 203 to rotate between the two limit plates 3, thereby driving the threaded collar 205 to move on the outer wall of the lead screw 203. The slider 204 at the bottom of the threaded collar 205 slides in the slide groove 101. The limit slide rod 206 slides in the limit groove 102 with the movement of the slider 204, which moves the threaded collar 205 to limit the movement. This causes the crosshair transmitter 6 to move under the support of the bracket 1, so that it coincides with one of the positioning lines of the workpiece on the positioning turntable 4.

[0041] Example 2

[0042] The difference from Embodiment 1 is that this embodiment discloses a rotating component 7 comprising:

[0043] The toothed swivel ring 701 is fixedly sleeved with the outer wall of the support column 8 at its middle part. Two rolling columns 702 are slidably connected to the outer wall of the toothed swivel ring 701. Limiting frames 703 are rotatably connected to the middle part of the two rolling columns 702. A vertical plate 704 is fixedly connected to the right side of the two limiting frames 703. The bottom end of the vertical plate 704 is fixedly connected to the top end of the base 5 near the right side.

[0044] The drive mechanism is located on the right side of the outer wall of the toothed ring 701 and is used to drive the toothed ring 701 to rotate.

[0045] The drive mechanism includes a gear 706, the outer wall of which meshes with the outer wall of the toothed rotating ring 701. Support plates 705 are movably connected to the top and bottom ends of the gear 706. The right sides of the two support plates 705 are fixedly connected to the upright plate 704. A rotary motor 707 is fixedly connected to the top of one support plate 705. The transmission end of the rotary motor 707 passes through the support plate 705 and is fixedly connected to the gear 706.

[0046] In this embodiment, as Figure 1-4 As shown, when the rotary motor 707 is turned on, the gear 706 rotates under the action of the reducer, which in turn drives the toothed rotating ring 701 that meshes with it to rotate, thereby driving the support column 8 and the positioning turntable 4 to rotate. Under the action of the sensor, when a red line cursor 9 moves to the direction connecting the twelve o'clock and six o'clock positions, the controller controls the rotary motor 707 to turn off, and then turns on the moving component 2 to drive the cross cursor transmitter 6 to coincide with any red line cursor 9. When there is a red line cursor 9 that does not coincide, the rotary motor 707 is turned on, driving the support column 8 and the positioning turntable 4 to continue rotating until they coincide with the cursor of the cross cursor transmitter 6.

[0047] The working principle of this utility model is as follows: When positioning the workpiece at the top of the positioning turntable 4, the crosshair transmitter 6 is activated. Supported by the fixed plate 201, the moving motor 202 is simultaneously activated, driving the lead screw 203 to rotate between the two limiting plates 3. This, in turn, drives the threaded collar 205 to move along the outer wall of the lead screw 203. The slider 204 at the bottom of the threaded collar 205 slides within the slide groove 101. The limiting slide rod 206 slides within the limiting groove 102 as the slider 204 moves, thus limiting the movement of the threaded collar 205. This facilitates the movement of the crosshair transmitter 6 under the support of the bracket 1, ensuring it coincides with one of the positioning lines of the workpiece at the positioning turntable 4. The vertical plate 704 and the two… Supported by the support plate 705, the rotary motor 707 is turned on, and the gear 706 is driven to rotate under the action of the reducer. This drives the toothed rotating ring 701 that meshes with it to rotate, which in turn drives the support column 8 and the positioning turntable 4 to rotate. Under the action of the sensor, when a red line cursor 9 moves to the direction connecting the twelve o'clock and six o'clock positions, the controller controls the rotary motor 707 to turn off, and then turns on the moving component 2 to drive the cross cursor transmitter 6 to coincide with any red line cursor 9. When there is a red line cursor 9 that does not coincide, the rotary motor 707 is turned on, and the support column 8 and the positioning turntable 4 continue to rotate until they coincide with the cursor of the cross cursor transmitter 6, so as to quickly position and correct the offset workpiece.
