Description

Technical Field

[0001] This utility model relates to the field of workpiece assembly and transfer technology, and in particular to a positioning structure for assembly and transfer. Background Technology

[0002] Existing assembly-type processing flows mostly involve assembling the product on a separate operating platform, then transferring the assembled semi-finished product to a transfer cart, and finally moving it to the next process. However, for some highly sensitive products, the more times they are transferred, the greater the chance of damage due to vibration, collision, or other factors. Therefore, it is necessary to complete the assembly directly on the transfer cart to facilitate the rapid transfer of products between different locations. Most existing transfer carts are not equipped with suitable assembly operating platforms, failing to strike a balance between positioning the workpiece and exposing the assembly window. This makes it impossible to effectively guarantee assembly efficiency and quality. In addition, for heavy workpieces with a circular cross-section, such as cylindrical, frustum-shaped, or conical workpieces, existing assembly operation platforms either use V-blocks for positioning or use elastic positioning blocks to clamp the workpiece. For the former, the contact area between the V-block and the outer surface of the workpiece is limited. When applied to dynamic operations such as transfer, it is very easy for the workpiece to roll accidentally and deviate from the V-block. For the latter, the elastic positioning blocks need to be repeatedly compressed and released during operation. After long-term use, they are prone to elastic fatigue, which will also affect the reliability of transfer positioning. Utility Model Content

[0003] The main purpose of this utility model is to provide an assembly and transfer positioning structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] The assembly and transfer positioning structure includes a positioning component, which includes a positioning platform, a positioning seat mounted on the positioning platform, a positioning support at the top of the positioning seat, and symmetrical positioning arc surfaces at the left and right ends of the positioning support.

[0006] The positioning platform is rotatably equipped with left and right positioning lead screws arranged in a left-right direction. The left and right positioning lead screws have a left-hand lead screw section and a right-hand lead screw section located to the right of the left-hand lead screw section and in the opposite direction to the left-hand lead screw section. Both the left-hand lead screw section and the right-hand lead screw section are fitted with positioning left and right positioning nut seats. Both positioning left and right positioning nut seats are connected to positioning support frames. The two positioning support frames are symmetrically arranged on both sides of the positioning base. The inner end of the positioning support frame is rotatably equipped with a positioning support wheel located above the positioning support.

[0007] Furthermore, the positioning bracket has a recessed relief groove in the middle that extends through its front and rear ends, and the relief groove is located in the area between the two positioning arc surfaces.

[0008] Furthermore, the positioning seat has positioning openings extending through its left and right ends, and the positioning left and right lead screws pass through the positioning openings and are mounted on the positioning platform;

[0009] The two positioning support wheels are respectively positioned in the middle area of ​​the left and right ends of the positioning bracket.

[0010] Furthermore, a positioning support shaft is rotatably connected to the positioning support frame, and the positioning support wheel is sleeved on the positioning support shaft.

[0011] A positioning locking gear is connected to the positioning support shaft, and a number of locking tooth grooves are provided on the ring surface of the positioning locking gear.

[0012] The positioning support frame is also slidably provided with a support wheel locking pin, and the inner end of the support wheel locking pin can pass through the positioning support frame and be inserted into the locking tooth groove.

[0013] Furthermore, both ends of the positioning left and right lead screws are connected to positioning left and right handles.

[0014] Furthermore, the positioning platform is also provided with positioning left and right guide rails parallel to the positioning left and right lead screws, and the bottom end of the positioning support frame is provided with positioning left and right sliders that can cooperate with the positioning left and right guide rails.

[0015] Furthermore, positioning scales are provided at both ends of the positioning platform.

[0016] The positioning support frame is connected to a positioning left and right indicator needle that can cooperate with the positioning left and right scale.

[0017] Furthermore, the positioning component also includes a positioning support base, on which positioning upper and lower nut seats are provided, and the bottom end of the positioning platform is provided with positioning upper and lower lead screws that can penetrate and cooperate with the positioning upper and lower nut seats.

[0018] Furthermore, the bottom end of the positioning upper and lower lead screw is connected to a positioning upper and lower handle.

[0019] Furthermore, the positioning support is also provided with upper and lower positioning guide cylinders;

[0020] The bottom of the positioning platform is provided with a positioning upper and lower guide rod that can penetrate and cooperate with the positioning upper and lower guide cylinders.

[0021] Furthermore, it also includes a positioning support platform, on which several positioning components are provided.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] like Figure 1-6 As shown, the assembly and transfer positioning structure includes a positioning component, which includes a positioning platform 1, a positioning seat 2 installed on the positioning platform 1, a positioning support 3 at the top of the positioning seat 2, and symmetrical positioning arc surfaces 5 at the left and right ends of the positioning support 3.

[0033] Positioning left and right lead screws 6 are rotatably arranged on the positioning table 1. The positioning left and right lead screws 6 have a left-hand lead screw section 7 and a right-hand lead screw section 8 located to the right of the left-hand lead screw section 7 and in the opposite direction to the left-hand lead screw section 7. Positioning left and right nut seats 9 are fitted on both the left-hand lead screw section 7 and the right-hand lead screw section 8. Positioning support frames 10 are connected to both positioning left and right nut seats 9. The two positioning support frames 10 are symmetrically arranged on both sides of the positioning seat 2. Positioning support wheels 11 located above the positioning support 3 are rotatably arranged on the inner end of the positioning support frame 10.

[0034] In this embodiment, the left and right positioning screws 6 are first rotated so that the two positioning left and right nut seats 9 on the left-hand screw segment 7 and the right-hand screw segment 8 move in opposite directions relative to the positioning support 3. Then, the workpiece to be positioned is placed on the positioning support 3 in a front-back direction. The two positioning arc surfaces 5 are designed to support and position the bottom of the workpiece with a circular cross-section. Then, the left and right positioning screws 6 are rotated in the opposite direction so that the two positioning left and right nut seats 9 on the left-hand screw segment 7 and the right-hand screw segment 8 move in opposite directions relative to the positioning support 3 until the two positioning support wheels 11 abut against the left and right sides of the workpiece with a circular cross-section. This can effectively position the workpiece and prevent it from moving during assembly and transportation, which would affect the processing quality and efficiency.

[0035] The spacing between the two positioning support wheels 11 is controlled by positioning the left and right lead screws 6, which can avoid problems such as elastic fatigue and effectively improve service life and operational reliability.

[0036] Among them, the positioning bracket 3 can be made of polyurethane, and the positioning support wheel 11 can be made of plastic, so as to avoid damaging the workpiece.

[0037] In application, multiple front-to-back arrangements of this embodiment can be used to position the same workpiece according to its length.

[0038] Preferably, the positioning support 3 has a recessed relief groove 4 in the middle that extends through its front and rear ends, and the relief groove 4 is located in the area between the two positioning arc surfaces 5.

[0039] In this embodiment, the design of the relief groove 4 can be used to make way for the bottom end of the workpiece to be positioned, thereby improving the versatility of the positioning structure. Specifically, when the outer diameter of the workpiece is small, the relief groove 4 can partially accommodate the bottom end of the workpiece so that the positioning arc surface 5 can more closely support the workpiece.

[0040] For structural optimization, preferably, the positioning seat 2 has a positioning port 24 extending through its left and right ends, and the positioning left and right lead screws 6 pass through the positioning port 24 and are mounted on the positioning platform 1; the two positioning support wheels 11 are respectively positioned in the middle area of ​​the left and right ends of the positioning support 3.

[0041] In this embodiment, the positional relationship between the two positioning support wheels 11 and the positioning bracket 3 can better position the workpiece with a circular cross-section.

[0042] To facilitate the installation of the left and right positioning lead screws 6, preferably, the positioning platform 1 is provided with two symmetrically arranged lead screw mounting seats 12, and the two ends of the left and right positioning lead screws 6 are mounted on the two lead screw mounting seats 12 through bearings.

[0043] The two lead screw mounting bases 12 can also limit the extreme positions of the movement of the two positioning left and right nut seats 9.

[0044] Preferably, a positioning support shaft 25 is rotatably connected to the positioning support frame 10, and the positioning support wheel 11 is sleeved on the positioning support shaft 25.

[0045] A positioning locking gear 26 is connected to the positioning support shaft 25, and a plurality of locking grooves 27 are provided on the ring surface of the positioning locking gear 26.

[0046] The positioning support frame 10 is also slidably provided with a support wheel locking pin 28, the inner end of which can pass through the positioning support frame 10 and be inserted into the locking tooth groove 27.

[0047] In this embodiment, through the cooperation of the support wheel locking pin 28 and the locking gear 26, when the workpiece needs to be rotated slightly during the assembly process, the support wheel locking pin 28 can be slid to disengage it from the locking tooth groove 27, maintaining the rotatability of the positioning support wheel 11. In this way, the friction between the workpiece and the positioning support wheel 11 can be reduced, effectively reducing the wear on the workpiece. When the workpiece needs to be transferred, the support wheel locking pin 28 can be slid to be placed into the locking tooth groove 27, which will lock the circumferential position of the locking gear 26, and thus lock the circumferential position of the positioning support wheel 11. The non-rotating positioning support wheel 11 can better position the workpiece.

[0048] like Figure 5 As shown, both the front and rear ends of the positioning support frame 10 are provided with locking pin holes 30 for the locking pins 28 of the support wheels to be inserted, so that the operator can lock the positioning support wheels 11 from both the front and rear sides. Figure 4 As shown, the support wheel locking pin 28 has a locking pin limiting section 29 with an outer diameter larger than the inner diameter of the locking pin hole 30. This can prevent the support wheel locking pin 28 from moving excessively and damaging the positioning support wheel 11.

[0049] The rotatable design of the positioning support wheel 11 can effectively reduce wear on the workpiece.

[0050] To facilitate the rotation of the left and right positioning lead screws 6, preferably, both ends of the left and right positioning lead screws 6 are connected to left and right positioning handles 13.

[0051] Preferably, the positioning platform 1 is further provided with a positioning left and right guide rail 14 parallel to the positioning left and right lead screw 6, and the bottom end of the positioning support frame 10 is provided with a positioning left and right slider 15 that can cooperate with the positioning left and right guide rail 14.

[0052] In this embodiment, the stability of the two positioning left and right guide rails 14 and positioning left and right sliders 15 can be improved by cooperating with each other.

[0053] like Figure 3 As shown, two positioning left and right guide rails 14 can be provided. Both positioning left and right guide rails 14 pass through the positioning port 24 and are set on the positioning table 1. The two positioning left and right guide rails 14 are located on the front and rear sides of the positioning left and right lead screw 6, respectively. Each positioning support frame 10 is provided with two positioning left and right sliders 15 that cooperate with the two positioning left and right guide rails 14, respectively.

[0054] Preferably, positioning scales 16 are provided at both the left and right ends of the positioning platform 1;

[0055] The positioning support frame 10 is connected to a positioning left and right indicator needle 17 that can cooperate with the positioning left and right scale 16.

[0056] This embodiment is a manual operation positioning structure. By setting the left and right positioning indicator pins 17 and the left and right positioning scales 16, the operator can easily know the displacement of the two positioning support wheels 11 to better position the workpiece.

[0057] Preferably, the positioning component further includes a positioning support 18, on which a positioning upper and lower nut seat 19 is provided, and at the bottom end of the positioning platform 1, a positioning upper and lower lead screw 20 is provided that can penetrate and cooperate with the positioning upper and lower nut seat 19.

[0058] In this embodiment, rotating the upper and lower positioning screws 20 allows the positioning platform 1 to move up and down through the cooperation of the upper and lower positioning screws 20 and the upper and lower positioning nut seats 19.

[0059] Preferably, it also includes a positioning support platform 31, on which a plurality of the positioning components are provided.

[0060] By connecting the positioning support seats 18 of each positioning component to the positioning support platform, when the workpiece is frustum or cone-shaped, the height position of the positioning platform 1 in each positioning component can be adjusted to adapt to the shape of the workpiece and provide a more fitting positioning. This makes it more versatile and can accommodate workpieces of more shapes and inclinations.

[0061] To facilitate the rotation of the positioning upper and lower lead screws 20, preferably, the bottom end of the positioning upper and lower lead screws 20 is connected to a positioning upper and lower handle 21.

[0062] Preferably, the positioning support 18 is further provided with a positioning upper and lower guide cylinder 22;

[0063] The bottom end of the positioning platform 1 is provided with a positioning upper and lower guide rod 23 that can penetrate and cooperate with the positioning upper and lower guide cylinder 22.

[0064] In this embodiment, the stability of the overall vertical movement of the positioning platform 1 can be improved by the cooperation of the positioning upper and lower guide rods 23 and the positioning upper and lower guide cylinders 22.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
