Technical Field

[0001] The utility model relates to the technical field of bathtub processing, in particular to a positioning fixture for bathtub glaze spraying processing. Background Art

[0002] A bathtub is a component used for bathing or showering. When processing a bathtub, it is usually necessary to spray glaze on the surface of the bathtub. In order to ensure the stability of the bathtub when spraying the glaze, most of the time, a positioning fixture is used to limit the bathtub.

[0003] For example, a multi-model bathtub clamping and positioning device and method with publication number CN112706076A includes a support platform, a positioning pin and a clamping mechanism. The positioning pin is detachably connected to the support platform and is used to be inserted into the drain hole of the bathtub; the clamping mechanism includes a guide rod, a left clamping plate, a right clamping plate, a left driving member and a right driving member. The guide rod is horizontally arranged and fixed on the support platform, the left clamping plate and the right clamping plate are respectively slidably arranged at both ends of the guide rod, and the left driving member and the right driving member are used to drive the left clamping plate and the right clamping plate respectively, so that the left clamping plate and the right clamping plate are clamped on both sides of the bathtub.

[0004] The above-mentioned prior art has the following technical problems: when the existing positioning device positions the bathtub, the clamping part of the existing positioning device makes hard contact with the bathtub, so when the clamping force is too large, it is easy to cause damage to the surface of the bathtub. At the same time, the surface of the bathtub is usually an inclined surface, and when the clamping part clamps the bathtub, the fit between the clamping part and the bathtub surface is poor, thereby reducing the fixing effect of the bathtub as a whole.

[0005] Therefore, we propose a positioning fixture for bathtub glaze processing to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a positioning fixture for bathtub glaze processing, so as to solve the problem proposed in the above background technology that the existing positioning devices on the market have a hard contact between the clamping part and the bathtub when positioning the bathtub, so that when the clamping force is too large, it is easy to cause damage to the surface of the bathtub. At the same time, the surface of the bathtub is usually an inclined surface, and the clamping part has a poor fit with the bathtub surface when clamping the bathtub, thereby reducing the fixing effect of the bathtub as a whole.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning fixture for bathtub glaze spraying processing, comprising a support seat, wherein locking bolts are installed on the left and right sides of the lower end of the support seat, and are used to lock and install with external objects through the locking bolts;

[0008] Also includes:

[0009] A dual-axis motor is fixedly installed on the inner side of the middle part of the support seat, and the left and right output ends of the dual-axis motor are fixedly connected with driving screws, a limit clamp is installed on the driving screw, and a guide column is installed through the limit clamp, and the guide column is fixedly installed on the support seat;

[0010] A connecting base plate is arranged inside the upper end of the limit clamp block, and an adjusting rod is installed through the connecting base plate, and the adjusting rod is connected to the connecting base plate through an auxiliary spring, and the upper and lower ends of the connecting base plate are connected to the limit clamp block through a buffer mechanism.

[0011] Preferably, the threads on the surfaces of the driving screws on the left and right sides of the dual-axis motor have opposite directions, and the driving screws and the limiting clamps are threadedly connected.

[0012] By adopting the above technical solution, the threads on the surfaces of the left and right driving screws are opposite, so that the two limit clamps can move synchronously relative to each other.

[0013] Preferably, the limiting clamp block and the guide column are vertically distributed, and the limiting clamp block and the guide column are slidably connected.

[0014] By adopting the above technical solution, the limiting clamp block slides on the guide column, thereby preventing the limiting clamp block from rotating synchronously with the driving screw.

[0015] Preferably, the adjusting rods are evenly distributed at equal intervals on the connecting substrate, and both left and right ends of the adjusting rods are spherical rubber ends, and the adjusting rods form an elastic telescopic structure through an auxiliary spring and the connecting substrate.

[0016] By adopting the above technical solution, the corresponding adjusting rod is moved and adjusted on the connecting base plate, so that it can adapt to the inclination of the bathtub surface, increase the contact area with the bathtub surface, and improve the stability of bathtub positioning.

[0017] Preferably, the buffer mechanism includes a guide rod, and the guide rod is used to connect the moving block and the connecting substrate, the moving block is located inside the limiting groove, and the limiting groove is opened on the connecting substrate, and the moving blocks are connected to each other through a reset spring.

[0018] By adopting the above technical solution, the reset spring can be provided to enable the moving block to reset and rebound after moving inside the limiting groove.

[0019] Preferably, both ends of the guide rod are hingedly connected to the moving block and the connecting base plate respectively, and the moving block and the guide rod are symmetrically arranged with respect to the transverse center axis of the connecting base plate.

[0020] By adopting the above technical solution, when the connecting base plate moves, the moving block can be moved synchronously through the hinged guide rod.

[0021] Preferably, the outer wall of the moving block and the inner wall of the limiting groove fit each other, and the moving block and the limiting groove are slidably connected.

[0022] By adopting the above technical solution, the outer wall of the moving block and the inner wall of the limiting groove fit each other, thereby improving the stability of the moving block when moving in the limiting groove.

[0023] Compared with the prior art, the utility model has the following beneficial effects: the positioning fixture for bathtub glaze spraying can conveniently play a clamping and buffering role on the bathtub during use, thereby avoiding damage to the bathtub caused by excessive clamping force, and at the same time can increase the contact area between the clamping component and the bathtub surface, thereby increasing the stability of bathtub positioning;

[0024] 1. Set a limit clamp. Because the threads on the left and right sides of the dual-axis motor drive screw surface have opposite directions, when the drive screw rotates, the two limit clamps can move relative to each other synchronously. The relative movement of the limit clamps can facilitate the clamping and positioning of the bathtub;

[0025] 2. A connecting base plate is provided. When the limit clamping block positions the bathtub, the spherical rubber end of the adjusting rod contacts the bathtub. The elastic deformation of the spherical rubber end of the adjusting rod can play a preliminary clamping and buffering role. At the same time, the movement of different adjusting rods on the connecting base plate can be used to adapt the multiple adjusting rods to the inclined surface of the bathtub, thereby increasing the contact area with the bathtub surface and increasing the stability of the bathtub when positioning;

[0026] 3. An adjusting rod is provided. Since both the left and right ends of the adjusting rod are provided with spherical rubber ends, when the inner surface of the bathtub is sprayed with glaze, the spherical rubber ends at the inner end of the adjusting rod contact and position the left and right sides of the bathtub, and when the outer surface of the bathtub is sprayed with glaze, the spherical rubber ends at the outer end of the adjusting rod contact and position the inner surface of the bathtub, so as to avoid the clamping part being blocked when spraying glaze on the bathtub and the glaze cannot be sprayed;

[0027] 4. A guide rod is provided. When the adjusting rod moves to the limit distance, the connecting base plate is subjected to force and the moving block can be moved inside the limiting groove through the hinged guide rod. The movement of the moving block can play a clamping and buffering role through the elastic deformation of the return spring, thereby avoiding damage to the surface of the bathtub due to excessive clamping force.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example 1: Please refer to Figure 1-Figure 2 , the rotation of the driving screws 4 on the left and right sides of the double-axis motor 3 can make the threaded limit clamp 5 move toward the inner side of the support seat 1, and the relatively movable limit clamp 5 is used to position the bathtub. This embodiment discloses the following technical content: a positioning fixture for bathtub glaze spraying processing, including a support seat 1, and locking bolts 2 are installed on the left and right sides of the lower end of the support seat 1, and the locking bolts 2 are used to lock and install with external objects; a double-axis motor 3 is fixedly installed on the inner side of the middle part of the support seat 1, and the left and right output ends of the double-axis motor 3 are fixedly connected with the driving screws 4, and the limit clamp 5 is installed on the driving screw 4, and the limit clamp 5 is penetrated and installed with a guide column 6, and the guide column 6 is fixedly installed on the support seat 1; the threads on the surfaces of the driving screws 4 on the left and right sides of the double-axis motor 3 are opposite, and the driving screw 4 and the limit clamp 5 are threadedly connected. The limit clamp 5 and the guide column 6 are vertically distributed, and the limit clamp 5 and the guide column 6 are slidably connected.

[0036] When it is necessary to spray glaze on the inner surface of the bathtub, the double-axis motor 3 controls the driving screw 4 to rotate, so that the threaded limit clamp 5 moves toward the outer side of the support seat 1 to the limit distance, and then the bathtub is placed in the middle of the support seat 1. At this time, the double-axis motor 3 controls the driving screw 4 to rotate in the opposite direction, and the threaded limit clamp 5 moves toward the inner side of the guide column 6, so that the outer surface of the bathtub can be clamped and positioned. When it is necessary to spray glaze on the outer surface of the bathtub, the double-axis motor 3 controls the driving screw 4 to rotate, so that the threaded limit clamp 5 moves toward the inner side of the support seat 1 to the limit distance, and then the bathtub is inverted in the middle of the support seat 1. At this time, the double-axis motor 3 controls the driving screw 4 to rotate, so that the limit clamp 5 moves toward the outer side of the bathtub, so that the limit clamp 5 is used to resist the inner surface of the bathtub, so as to position the bathtub. In this way, it is avoided that when spraying glaze, part of the surface of the bathtub is blocked by the clamping part and cannot be sprayed with glaze.

[0037] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above embodiment 1. The surface of the bathtub is usually an inclined surface. When the clamping component is clamped on the bathtub, the fit between the bathtub surface and the clamping component is poor, thereby reducing the fixing effect of the bathtub as a whole. Figure 1-Figure 4 As shown, a connecting base plate 7 is provided on the inner side of the upper end of the limiting clamp 5, and an adjusting rod 8 is installed through the connecting base plate 7, and the adjusting rod 8 is connected to the connecting base plate 7 through an auxiliary spring 9, the adjusting rod 8 is evenly distributed on the connecting base plate 7 at equal intervals, and the left and right ends of the adjusting rod 8 are both spherical rubber ends, and the adjusting rod 8 forms an elastic telescopic structure through the auxiliary spring 9 and the connecting base plate 7.

[0038] When the limiting clamp 5 moves to clamp and position the bathtub, first the rubber spherical end of the adjusting rod 8 contacts the bathtub, and the rubber spherical end of the adjusting rod 8 is elastically deformed, thereby playing a clamping and buffering role. At the same time, different adjusting rods 8 on the connecting base plate 7 can slide after being stressed, and the movement and adjustment of different adjusting rods 8 can make them adapt to the inclined surface of the bathtub, thereby increasing the contact area with the bathtub surface when clamping the bathtub and increasing the stability when positioning the bathtub.

[0039] Embodiment 3: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiments 1 and 2. When the existing positioning device positions the bathtub, its clamping part makes hard contact with the bathtub, so when the clamping force is too large, it is easy to cause damage to the surface of the bathtub, such as Figure 2-Figure 5As shown, the upper and lower ends of the connecting substrate 7 are interconnected with the limiting clamp block 5 through a buffer mechanism 10. The buffer mechanism 10 includes a guide rod 101, and the guide rod 101 is used to connect the moving block 102 and the connecting substrate 7, the moving block 102 is located inside the limiting groove 103, and the limiting groove 103 is provided on the connecting substrate 7, and the moving blocks 102 are interconnected through a reset spring 104. The two ends of the guide rod 101 are respectively hingedly connected to the moving block 102 and the connecting substrate 7, and the moving block 102 and the guide rod 101 are symmetrically arranged about the transverse center axis of the connecting substrate 7. The outer wall of the moving block 102 and the inner wall of the limiting groove 103 fit each other, and the moving block 102 and the limiting groove 103 are slidably connected.

[0040] When positioning the bathtub, after the adjusting rod 8 moves to the limit distance on the connecting base plate 7, the connecting base plate 7 can be subjected to force to enable the moving block 102 to move inside the limiting groove 103 through the hinged guide rod 101. When the moving block 102 moves inside the limiting groove 103, the elastic deformation of the return spring 104 is utilized to clamp and buffer the bathtub, thereby avoiding damage to the bathtub due to excessive clamping force.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
