Description

Technical Field

[0001] The utility model relates to the technical field of ashtray jigs, in particular to an ashtray positioning jig. Background Art

[0002] With the increasing improvement of people's living standards, people have put forward higher and higher requirements for the appearance of ashtrays. In order to meet people's needs for the appearance of ashtrays, manufacturers generally carry out laser engraving on ashtrays to engrave various patterns on the ashtrays, including patterns such as the manufacturer's trademark. There is a notch on the ashtray for users to place cigarettes. In order to improve the aesthetics of the ashtray, the laser engraving pattern on the ashtray should be located at a preset position, and the angle between the laser engraving pattern and the notch should be kept consistent.

[0003] Since the laser head cannot perform rotational movement during laser engraving, when laser engraving an ashtray with a laser engraving machine, the ashtray needs to be placed on a corresponding jig. The preset position of the ashtray is determined by the position of the jig, and the rotation of the ashtray is used to ensure that the angle between the laser engraving pattern on the ashtray and the notch is kept consistent. Since ashtrays have different diameters, corresponding jigs of different sizes need to be designed for each size of ashtray to ensure that the angle between the laser engraving pattern on the ashtray and the notch is kept consistent, resulting in a large number of jigs and high costs. Therefore, it is necessary to design a jig that can adapt to different diameters of ashtrays. Summary of the Utility Model

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Referring to Figures 1 to 8 As shown, the ashtray positioning fixture of the present utility model includes a fixture base 1 for placing the ashtray. A first positioning plate 2 and a second positioning plate 3 are provided on the fixture base 1. A preset included angle is provided between the first positioning plate 2 and the second positioning plate 3. A notch positioning mechanism 4 is slidably provided on the first positioning plate 2. The notch positioning mechanism 4 cooperates with the fixture base 1, the first positioning plate 2 and the second positioning plate 3 to place the ashtray in a preset position and a preset angle.

[0030] The ashtray positioning fixture of the present application includes a fixture base 1, on which a first positioning plate 2 and a second positioning plate 3 are provided. A notch positioning mechanism 4 is slidably arranged on the first positioning plate 2. Through the cooperation of the first positioning plate 2, the second positioning plate 3, the notch positioning mechanism 4 and the fixture base 1, the ashtray positioning fixture can achieve universal positioning for ashtrays with different diameters. Specifically, the pattern engraved by the laser head on the ashtray needs to be located at a preset position (generally the central position) of the ashtray, and the laser engraved pattern and the notch on the ashtray need to be at a preset angle. Therefore, to ensure that the laser engraved pattern is located at the preset position of the ashtray, move the ashtray positioning fixture so that the axis of the ashtray on the ashtray positioning fixture coincides with the axis of the laser head (the ashtray is placed horizontally and the laser head is set vertically); to ensure that the laser engraved pattern and the ashtray notch are at a preset angle, move the notch positioning mechanism 4 to the corresponding position on the first positioning plate 2, and then rotate the ashtray so that the target notch (the notch cooperating with the notch positioning mechanism 4) on the ashtray is aligned with the position of the notch positioning mechanism 4. Among them, the notch positioning mechanism 4 is slidably arranged on the first positioning plate 2, so the position of the notch positioning mechanism 4 on the first positioning plate 2 can be adjusted. Since the notch positioning mechanism 4 cooperates with the notch on the ashtray, the angle between the laser engraved pattern and the ashtray notch can be adjusted by the position of the notch positioning mechanism 4 on the first positioning plate 2 to ensure that the laser engraved pattern and the ashtray notch are at a preset angle. Further, taking an ashtray with a circular cross-section as an example, the number of notches on the ashtray is three, and the three notches are arranged around the axis of the ashtray, and the angle between any two notches around the axis of the ashtray is 120° (the number of notches of the ashtray applied in the present application is taken as three, and the number of notches of the ashtray applicable to the ashtray positioning fixture is not limited). The specific working principle is as follows: Place the ashtray on the fixture base 1, and keep the circumferential side of the ashtray tangent to the first positioning plate 2 and the second positioning plate 3. At this time, the position of the ashtray relative to the fixture base 1 is fixed. By moving the fixture base 1, the axis of the ashtray can be made to coincide with the axis of the laser head, so that the pattern engraved by the laser head on the ashtray is located at the preset position of the ashtray ( Figure 5 the central position of the dotted circle shown); then move the notch positioning mechanism 4 to the corresponding position on the first positioning plate 2, and rotate any notch (any one of the three notches) of the ashtray to the position aligned with the notch positioning mechanism 4 to achieve the angular positioning of the ashtray on the fixture base 1, so as to ensure that when the ashtray is placed on the fixture base 1, the angle between the pattern laser engraved on the ashtray and the ashtray notch is the preset angle. As shown in Figure 6 , taking the font pattern of "ashtray" as an example, it can be ensured that the ashtray font is located relative to the positions of the three notches ( Figure 6 the three dotted positions arranged at intervals of 120° in the figure) at Figure 6The state shown prevents the font of the ashtray from being skewed relative to the three notches, which affects the appearance. Among them, since the ashtrays have different diameters, when ashtrays with different diameters are placed on the fixture base 1, the positions of the notch positioning mechanism 4 are different. Therefore, the notch positioning mechanism 4 is slidably arranged on the first positioning plate 2. When positioning ashtrays with different diameters, it is only necessary to move the notch positioning mechanism 4 to a position corresponding to the diameter of the ashtray, so as to ensure that the angle between the pattern laser-engraved on the ashtray and the notch of the ashtray is a preset angle. Only one fixture base 1 can be used to position ashtrays with various diameters, improving the versatility and reducing the cost. Among them, during the use of the ashtray positioning fixture in this application, the fixture base 1 can linearly slide relative to the laser head, but the relative angle between the fixture base 1 and the laser head should be fixedly set (equivalent to the angular position of the pattern engraved by the fixture base 1 and the laser head), so as to ensure that when the ashtray is rotated until the notch is aligned with the notch positioning mechanism 4, the angle between the laser-engraved pattern formed on the ashtray and the notch is the preset angle.

[0031] In one of the embodiments, the fixture base 1 cooperates with the first positioning plate 2 and the second positioning plate 3 to place the ashtray at the preset position.

[0032] As Figure 3 shown, place the ashtray on the fixture base 1 and keep the circumferential side of the ashtray tangent to the first positioning plate 2 and the second positioning plate 3. At this time, the position of the ashtray relative to the fixture base 1 is fixed. Then, by moving the fixture base 1, the ashtray can be placed at the preset position, that is, the axis of the ashtray coincides with the axis of the laser head, which is convenient for laser engraving.

[0033] In one of the embodiments, the first positioning plate 2 is provided with a first slide rail 5 and a first scale 7. The notch positioning mechanism 4 includes a first slider 6 and a first scale pointer 8. The first slider 6 is slidably arranged on the slide rail. The first scale 7 and the first scale pointer 8 are used to determine the position of the notch positioning mechanism 4 on the first positioning plate 2.

[0034] As Figure 1 and Figure 2As shown, the notch positioning mechanism 4 is slidably arranged on the first positioning plate 2. Specifically, the notch positioning mechanism 4 includes a first slider 6, and a first slide rail 5 is arranged on the first positioning plate 2. The first slider 6 is slidably arranged on the first slide rail 5, so that the sliding of the notch positioning mechanism 4 on the first positioning plate 2 is realized through the cooperation of the first slider 6 and the first slide rail 5. The ashtray positioning jig further includes a first scale 7 and a first scale pointer 8. Through the cooperation of the first scale 7 and the first scale pointer 8, the notch positioning mechanism 4 is moved to a corresponding position on the first positioning plate 2 to achieve angle positioning. Specifically, the first scale pointer 8 is arranged on the notch positioning mechanism 4, the first scale 7 is arranged on the first positioning plate 2, and the scale of the first scale 7 is arranged along the sliding direction of the notch positioning mechanism 4 on the first positioning plate 2. When the notch positioning mechanism 4 slides on the first positioning plate 2, the first scale pointer 8 moves synchronously, and the notch positioning mechanism 4 can be moved to a corresponding position on the first positioning plate 2 by relying on the cooperation of the first scale pointer 8 and the first scale 7. Among them, the first scale pointer 8 does not need to be provided with a separate structure, and one side surface of the U-shaped plate 9 can be used. For example, the diameter of ashtray A is φ1, and the scale position of the corresponding notch positioning mechanism 4 on the first positioning plate 2 is P1. The diameter of ashtray B is φ2, and the scale position of the corresponding notch positioning mechanism 4 on the first positioning plate 2 is P2; when laser engraving is required for ashtray A, the notch positioning mechanism 4 is slid on the first positioning plate 2 to the position with a scale of P1, then the ashtray is placed on the jig base 1, and the ashtray is placed in a tangential state with the first positioning plate 2 and the second positioning plate 3. Rotate ashtray A so that the target notch is aligned with the notch positioning mechanism 4, then ashtray A is placed at a preset angle, and at the same time the axis of the ashtray coincides with the axis of the laser head. At this time, the angle between the laser engraving pattern on the ashtray and the notch is the preset angle. When laser engraving is required for ashtray B, the notch positioning mechanism 4 is slid on the first positioning plate 2 to the position with a scale of P2, then the ashtray is placed on the jig base 1, and the ashtray is placed in a tangential state with the first positioning plate 2 and the second positioning plate 3. Rotate ashtray B so that the target notch is aligned with the notch positioning mechanism 4, then ashtray B is placed at a preset angle, and at the same time the axis of the ashtray coincides with the axis of the laser head. At this time, the angle between the laser engraving pattern on the ashtray and the notch is the preset angle.

[0035] In one of the embodiments, the notch positioning mechanism 4 includes a U-shaped plate 9 and a locking bolt 10. The locking bolt 10 passes through two side plates 12 of the U-shaped plate 9, and the locking bolt 10 is used to lock or unlock the two side plates 12 with the first positioning plate 2.

[0036] The notch positioning mechanism 4 needs to be moved to the corresponding position on the first positioning plate 2. After moving into place, the notch positioning mechanism 4 needs to be fixed on the first positioning plate 2 to prevent inaccurate positioning of the ashtray angle caused by the sliding of the notch positioning mechanism 4. Specifically, in addition to the first slider 6 and the first scale pointer 8, the notch positioning mechanism 4, as Figure 2 shown, further includes a U-shaped plate 9 and a locking bolt 10. The notch positioning mechanism 4 locks or unlocks the U-shaped plate 9 and the first positioning plate 2 through the cooperation of the U-shaped plate 9 and the locking bolt 10. Further, when the notch positioning mechanism 4 moves into place on the first positioning plate 2, by rotating the locking bolt 10, the two side plates 12 of the U-shaped plate 9 clamp the first positioning plate 2, realizing the locking of the notch positioning mechanism 4 and the first positioning plate 2; when it is necessary to move the notch positioning mechanism 4 on the first positioning plate 2, by rotating the locking bolt 10, the two side plates 12 of the U-shaped plate 9 are separated from the first positioning plate 2, realizing the unlocking of the notch positioning mechanism 4 and the first positioning plate 2.

[0037] In one embodiment, the notch positioning mechanism 4 further includes a first positioning portion 11. The first positioning portion 11 is disposed on the side plate 12 of the U-shaped plate 9 close to the ashtray. The first positioning portion 11 cooperates with the fixture base 1, the first positioning plate 2, and the second positioning plate 3 to place the ashtray at the preset angle.

[0038] The first positioning portion 11 of the notch positioning mechanism 4 cooperates with the fixture base 1, the first positioning plate 2, and the second positioning plate 3 to place the ashtray at the preset angle. Specifically, in addition to the U-shaped plate 9, the first slider 6, the locking bolt 10, and the first scale pointer 8, the notch positioning mechanism 4 further includes a first positioning portion 11, as Figure 2 shown. Further, the position positioning of the ashtray relative to the fixture base 1 is realized by the tangential setting with the first positioning plate 2 and the second positioning plate 3. By moving the fixture base 1, the ashtray can be placed at the preset position; then the notch positioning mechanism 4 realizes the cooperation with the notch on the ashtray through the first positioning portion 11, realizing the angle positioning of the ashtray on the fixture base 1, that is, aligning the first positioning portion 11 with the notch on the ashtray. Among them, the first positioning portion 11 is disposed on the side plate 12 of the U-shaped plate 9 close to the ashtray, and the contour of the first positioning portion 11 is consistent with the contour of the notch on the ashtray. The size of the first positioning portion 11 is slightly smaller than the size of the notch on the ashtray. In addition, a locking handle is provided on the locking bolt 10 to facilitate the user's operation of the locking bolt 10.

[0039] In one of the embodiments, an auxiliary positioning mechanism 13 is provided on the jig base 1. The auxiliary positioning mechanism 13 includes a support plate 14, a positioning screw 15, and a second positioning portion 16. The positioning screw 15 is rotatably provided on the support plate 14, and the second positioning portion 16 is provided at one end of the positioning screw 15 close to the first positioning plate 2.

[0040] An auxiliary positioning mechanism 13 is provided on the jig base 1 of the present application to improve the positioning reliability of the ashtray on the jig base 1 through the auxiliary positioning mechanism 13. Specifically, as Figure 1 shown, the auxiliary positioning mechanism 13 includes a support plate 14, a positioning screw 15, and a second positioning portion 16. The support plate 14 is used to support the positioning screw 15 and the second positioning portion 16. Further, the positioning screw 15 is threadedly connected to the support plate 14. The support plate 14 is perpendicular to the jig base 1. The axis of the positioning screw 15 preferably extends along the angular bisector direction (horizontal direction) of the first positioning plate 2 and the second positioning plate 3 to facilitate the positioning of the ashtray by the second support portion. One end of the positioning screw 15 far from the first positioning plate 2 is provided with a first adjustment handle 29. The second positioning portion 16 is provided at one end of the positioning screw 15 close to the first positioning plate 2. The rotation of the positioning screw 15 can cause the second positioning portion 16 to move closer to or away from the first positioning plate 2 along the axis direction of the positioning screw 15 (converting the rotational motion of the positioning screw 15 into a linear motion of the second positioning portion 16 along the axis direction of the positioning screw 15), so as to realize the abutting positioning and separation of the second positioning portion 16 on the ashtray. In addition, a rubber pad can be provided on the second positioning portion 16 to prevent the second positioning portion 16 from scratching the ashtray when positioning the ashtray through the auxiliary positioning mechanism 13.

[0041] In one of the embodiments, an operation table 17 is further included. A second slide rail 18 is provided on the operation table 17. A second slider 19 is provided on the jig base 1. The second slider 19 is slidably provided on the second slide rail 18. The sliding direction of the second slider 19 on the second slide rail 18 is the first direction, and the first direction is along the angular bisector direction of the first positioning plate 2 and the second positioning plate 3.

[0042] Since different ashtrays have different diameters, and the ashtray on the jig base 1 needs to be tangent to the first positioning plate 2 and the second positioning plate 3, when switching ashtrays with different diameters on the jig base 1, it is necessary to move the jig base 1 so that the axis of the ashtray on the jig base 1 coincides with the axis of the laser head, ensuring that the laser engraved pattern is located at the center of the ashtray. Specifically, as Figure 4 、 Figure 5 and Figure 6As shown, the ashtray positioning jig of the present application further includes an operation table 17. A second slide rail 18 is provided on the operation table 17, and a second slider 19 is provided at the bottom of the jig base 1. The second slider 19 is slidably arranged on the second slide rail 18. Therefore, through the cooperation of the second slide rail 18 and the second slider 19, the sliding movement of the jig base 1 relative to the operation table 17 can be realized, so as to slide the jig base 1 to a position where the axis of the ashtray coincides with the axis of the laser head. Since different ashtrays have different diameters, and the ashtray is in a tangent state with the first positioning plate 2 and the second positioning plate 3 on the jig base 1, when ashtrays with different diameters are placed on the jig base 1, the connecting line of the centers of different ashtrays is on the angular bisector of the first positioning plate 2 and the second positioning plate 3. Therefore, when it is necessary to move the jig base 1 so that the axis of the ashtray coincides with the axis of the laser head, only the jig base 1 needs to be moved in the first direction, that is, only the jig base 1 needs to be moved along the angular bisector direction of the first positioning plate 2 and the second positioning plate 3. At the same time, it is necessary to ensure that the axis of the laser head and the angular bisector of the first positioning plate 2 and the second positioning plate 3 have an intersection point, that is, the projection of the laser head on the jig base 1 in the vertical direction is on the angular bisector of the first positioning plate 2 and the second positioning plate 3. In addition, it is necessary to fix the angular position between the operation table 17 and the laser head (which is equivalent to the angular position between the operation table 17 and the pattern engraved by the laser head) to ensure that when the ashtray is rotated to align the notch with the notch positioning mechanism 4 and the jig base 1 is slid along the first direction, the angle between the laser engraving pattern formed on the ashtray and the notch is a preset angle.

[0043] In one of the embodiments, a second scale 20 is arranged on the operation table 17 along the first direction, and a second scale pointer 21 is arranged on the jig base 1. The second scale 20 and the second scale pointer 21 are used to determine the position of the jig base 1 on the operation table 17.

[0044] The position of the jig base 1 on the operation table 17 is determined by the cooperation of the second scale 20 and the second scale pointer 21. Specifically, as Figure 4As shown, a second scale 20 is provided on the operation table 17, and the scale of the second scale 20 is along the first direction, that is, along the angular bisector direction of the first positioning plate 2 and the second positioning plate 3; a second scale pointer 21 is provided on the jig base 1. When the jig base 1 makes a sliding movement along the first direction on the operation table 17, the jig base 1 can be moved to the corresponding position on the operation table 17 through the cooperation of the second scale pointer 21 and the second scale 20. Among them, the position of the jig base 1 on the operation table 17 is set corresponding to the diameter of the ashtray. For example, the diameter of ashtray A is φ1, and the scale position of the second scale pointer 21 on the second scale 20 is PP1. The diameter of ashtray B is φ2, and the scale position of the second scale pointer 21 on the second scale 20 is PP2. When ashtray A (with a diameter of φ1) is placed on the jig base 1, the second scale pointer 21 is moved to the scale position PP1 on the second scale 20. At this time, the axis of the ashtray on the jig base 1 coincides exactly with the axis of the laser head; when ashtray B (with a diameter of φ2) is placed on the jig base 1, the second scale pointer 21 is moved to the scale position PP2 on the second scale 20. At this time, the axis of the ashtray on the jig base 1 coincides exactly with the axis of the laser head, effectively improving the laser engraving efficiency.

[0045] In one of the embodiments, an adjusting screw 22 is further included. A support seat 23 is provided on the operation table 17. The adjusting screw 22 is provided on the support seat 23. The axis of the adjusting screw 22 is along the first direction. One end of the operation screw away from the support seat 23 is connected to the first positioning plate 2, the second positioning plate 3 or the jig base 1 to convert the rotational movement of the operation screw into the sliding movement of the jig base 1 on the operation table 17. A second adjusting handle 24 is provided at one end of the adjusting screw 22 away from the jig base 1.

[0046] The ashtray positioning jig of the present application further includes an adjusting screw 22 to adjust the position of the jig base 1 on the operation table 17. Specifically, such as Figure 4As shown in the figure, a support base 23 is provided on the operating table 17. The support base 23 is perpendicular to the operating table 17. The adjusting screw rod 22 is threadedly connected to the support base 23, and the axis of the adjusting screw rod 22 is along the first direction, that is, along the angular bisector direction of the first positioning plate 2 and the second positioning plate 3. Therefore, one end of the adjusting screw rod 22 close to the fixture base 1 is connected to the first positioning plate 2, the second positioning plate 3 or the fixture base 1, so as to convert the rotational movement of the adjusting screw rod 22 into the sliding movement of the fixture base 1 along the first direction, so as to realize the position adjustment of the fixture base 1 on the operating table 17 along the first direction. In addition, a second adjusting handle 24 is provided at one end of the adjusting screw rod 22 far from the fixture base 1, which facilitates the precise adjustment of the position of the fixture base 1 on the operating table 17.

[0047] In one of the embodiments, a connecting column 25 is provided at one end of the adjusting screw rod 22 connected to the fixture base 1. A connecting end 30 is formed at the connection of the first positioning plate 2 and the second positioning plate 3. A cylindrical groove 26 is provided on the connecting end 30. The connecting column 25 is rotatably arranged in the cylindrical groove 26. A blocking portion 27 is provided on the connecting end 30 to prevent the connecting column 25 from disengaging from the cylindrical groove 26.

[0048] By converting the rotational movement of the adjusting screw rod 22 into the sliding movement of the fixture base 1 along the first direction, the position adjustment of the fixture base 1 on the operating table 17 along the first direction is realized. Specifically, a connecting column 25 is provided at one end of the adjusting screw rod 22 close to the fixture base 1. A connecting end 30 is formed at the connection of the first positioning plate 2 and the second positioning plate 3. A cylindrical groove 26 is provided on the connecting end 30. When the adjusting screw rod 22 rotates, the connecting column 25 is rotatably arranged in the cylindrical groove 26. As Figure 7 and Figure 8As shown, a blocking portion 27 is further provided on the connection end 30. The connection column 25 is prevented from detaching from the cylindrical groove 26 through the blocking portion 27. Therefore, the connection column 25 can only perform a rotational movement in the cylindrical groove 26, and there is no sliding movement of the connection column 25 relative to the cylindrical groove 26 in the axial direction. The specific working principle is as follows: When the user rotates the adjusting screw 22, the adjusting screw 22 drives the connection column 25 to move. Therefore, the movement of the connection column 25 is a combined movement of rotational movement and linear sliding movement along its axis. The rotational movement of the connection column 25 along its axis is restricted in the cylindrical groove 26, and the linear movement of the connection column 25 along its axis drives the jig base 1 to perform a sliding movement on the operation table 17 in the first direction, so as to realize the position adjustment of the jig base 1 on the operation table 17. In addition, since the adjusting screw 22 and the support seat 23 are threadedly connected, relying on the self-locking function of the thread, when the user does not rotate the adjusting screw 22, the adjusting screw 22 will not generate a sliding movement along its axis, and the jig base 1 will not generate a sliding movement along its first direction on the operation table 17. Therefore, there is no need to provide an additional positioning mechanism to prevent the jig base 1 from moving relative to the operation table 17.
