Description

Technical Field

[0001] This utility model relates to the field of workpiece assembly and transfer technology, and in particular to a transfer vehicle that can assist in assembly operations. 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

[0053] 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.

[0054] like Figure 1-15 As shown, the transfer vehicle that can assist in assembly operations includes a main body 24 and an auxiliary body 25;

[0055] The main body 24 is provided with several main positioning components for positioning workpiece one, and the auxiliary body 25 is provided with several auxiliary positioning components for positioning workpiece two.

[0056] The main assembly connection components are provided at both the front and rear ends of the main body 24. The main assembly connection components include a main assembly base 26, and an assembly connection rod 27 is rotatably connected to the main assembly base 26.

[0057] The rear end of the sub-body 25 is provided with a sub-assembly connection assembly, which includes a sub-connector 28. The end of the assembly connecting rod 27 is detachably and rotatably connected to the sub-connector 28.

[0058] Preferably, the secondary connecting seat 28 is provided with a secondary connecting slot 46 that can accommodate the end of the assembly connecting rod 27, and the secondary assembly connecting assembly also includes a secondary connecting pin 29 that can pass through the secondary connecting seat 28 and the assembly connecting rod 27 vertically.

[0059] In this embodiment, as Figure 1 As shown, the sub-body 25 is located at the front end of the main body 24. Through the setting of the sub-connecting pin 29, a rotatable connection is formed between the assembly connecting rod 27 and the sub-connecting seat 28, as... Figure 9-10 As shown, the sub-body 25 can be turned to the left or right relative to the main body 24. In application, workpiece one is placed front-to-back on multiple main positioning components, and workpiece two is placed front-to-back on multiple sub-positioning components. By turning the sub-body 25, the area between workpiece two and workpiece one can be effectively exposed for assembly operations. The turning angle can be determined according to assembly requirements.

[0060] Since the main body 24 has main assembly connecting components at both the front and rear ends, the rear end of the main body 24 can also be connected to the reverse-mounted sub-body 25. Similarly, through the rotatable connection between the assembly connecting rod 27 and the sub-connecting seat 28, workpiece 2 can also be assembled at the rear end of workpiece 1.

[0061] When either of the front and rear main assembly connecting components is connected to the sub-body 25, the assembly connecting rod 27 in the other main assembly connecting component can be rotated and stored on the main body 24.

[0062] As can be seen, this embodiment divides the transfer vehicle into a main body and a secondary body that can be turned relative to each other. This makes it easier for workers to perform assembly operations directly on the transfer vehicle, thereby reducing the number of times the workpiece is transferred, effectively reducing the risk of collision damage, and thus improving assembly quality and efficiency.

[0063] like Figure 10 As shown, the secondary connecting seat 28 has two spaced-apart secondary connecting ears 67. The two connecting ears 67 and the secondary connecting seat 28 together form the secondary connecting slot 46, which extends through the rear end and both sides of the secondary connecting seat 28. An assembly connecting rod 27 is inserted between the two connecting ears 67, and a secondary connecting pin 29 passes through the two connecting ears 67 and the assembly connecting rod 27. This allows for a detachable and rotatable connection between the assembly connecting rod 27 and the secondary connecting seat 28. Figure 9 As shown, the assembly connecting rod 27 is rotatably connected to the main assembly base 26 via the main connecting pin 65.

[0064] Preferably, the main vehicle body 24 has two main wheels 42 at both the front and rear ends of the bottom end, and both the front and rear ends of the main vehicle body 24 are provided with a steering mechanism that can control the driving direction of the main wheels 42. The main vehicle body 24 is also provided with a brake assembly for braking the main wheels 42.

[0065] The main body 24 is also equipped with a hanging ring 54 and a storage box 45, and the main body 24 is also connected to an electrostatic grounding strip 43;

[0066] The sub-body 25 has two sub-wheels 44 at both the front and rear ends of its bottom.

[0067] In this embodiment, when workpiece 1 and workpiece 2 are fully assembled and need to be transported, the main vehicle body 24 is manually pushed through the steering operation mechanism and the driving direction of the main wheels 42 can be controlled. Due to the connection between the auxiliary vehicle body 25 and the main vehicle body 24, and the setting of the auxiliary wheels 44, the auxiliary vehicle body 25 will also move under the drive of the main vehicle body 24.

[0068] The braking assembly can be equipped with a handbrake, and the electrostatic grounding strip 43 can be used for grounding the workpiece, providing enhanced safety for certain highly sensitive products. The lifting ring 54 can be used for lifting with a transfer vehicle. The storage box 45 can be used to store assembly parts.

[0069] Preferably, the main assembly connecting component further includes main assembly left and right guide rails 30 arranged on the main vehicle body 24 and arranged in the left and right direction, and the bottom end of the main assembly seat 26 is provided with main assembly left and right sliders 31 that cooperate with the main assembly left and right guide rails 30.

[0070] The sub-assembly connecting component also includes sub-assembly left and right guide rails 32 arranged on the sub-body 25 and arranged in the left and right direction, and the front end of the sub-connecting seat 28 is provided with sub-assembly left and right sliders 33 that cooperate with the sub-assembly left and right guide rails 32.

[0071] In this embodiment, the position of the main assembly seat 26 can be adjusted by manually sliding the left and right sliders 31 of the main assembly, and the position of the secondary connecting seat 28 can be adjusted by manually sliding the left and right sliders 33 of the secondary assembly. This allows for adjustment of the position of the secondary vehicle body 25 relative to the main vehicle body 24, expanding the selection area for turning to better adapt to assembly requirements. The cooperation between the left and right guide rails 30 and the left and right sliders 31 of the main assembly improves the stability of the movement of the main assembly seat 26, and the cooperation between the left and right guide rails 32 and the left and right sliders 33 of the secondary assembly improves the stability of adjusting the movement of the secondary connecting seat 28.

[0072] Preferably, the main assembly connecting component further includes a main assembly left and right scale 34 disposed on the main vehicle body 24 and arranged in the left and right direction, and a main assembly left and right indicator needle 35 that can cooperate with the main assembly left and right scale 34 is connected to the main assembly base 26.

[0073] The sub-assembly connecting component also includes a sub-assembly left and right scale 36 arranged on the sub-body 25 and in the left and right direction, and a sub-assembly left and right indicator needle 37 that can cooperate with the sub-assembly left and right scale 36 is connected to the sub-connecting seat 28.

[0074] This embodiment is a manual operation. By setting the left and right scales 34 and left and right indicator needles 35 of the main assembly, the staff can easily know the specific displacement and position status of the main assembly seat 26. Similarly, by setting the left and right scales 36 and left and right indicator needles 37 of the auxiliary assembly, the staff can easily know the specific displacement and position status of the auxiliary connecting seat 28.

[0075] Preferably, limit components are provided at both the front and rear ends of the main vehicle body 24;

[0076] The limiting component includes a limiting seat 48 fixedly connected to the main vehicle body 24. A limiting groove 51 is provided on the limiting seat 48. A limiting plate 49 is slidably provided in the limiting groove 51. A limiting block 50 is provided on the inner side of the top end of the limiting plate 49.

[0077] The limiting assembly also includes a limiting locking screw 52 that is threaded onto the limiting seat 48 and can fix the height position of the limiting plate 49.

[0078] In this embodiment, to facilitate the rotation of the limiting locking screw 52, ​​a limiting locking handle 53 can be provided on the inner end of the limiting locking screw 52. In application, the outer end of the limiting locking screw 52 passes through the limiting seat 58 and is located in the limiting groove 51. By rotating the limiting locking screw 52, ​​the depth of the limiting locking screw 52 inserted into the limiting groove 51 can be adjusted to achieve the effect of locking the height position of the limiting plate 49 or unlocking it. In application, the height position of the limiting plate 49 can be adjusted according to the height position of workpiece one, so that the limiting blocks 50 of the two limiting components respectively limit the front and rear ends of workpiece one, thus preventing workpiece one from sliding forward and backward during transport. During transport, since the assembly of workpiece one and workpiece two has been completed, once the forward and backward position of workpiece one is limited, the forward and backward position of workpiece two is also relatively stable.

[0079] The limiting block 50 can be made of polyurethane material to avoid damaging the workpiece.

[0080] Preferably, both the main positioning component and the auxiliary positioning component include a positioning platform 1, a positioning seat 2 is mounted on the positioning platform 1, a positioning support 3 is provided at the top of the positioning seat 2, and the left and right ends of the positioning support 3 have symmetrical positioning arc surfaces 5.

[0081] Positioning left and right lead screws 6 are rotatably arranged on the positioning platform 1. The positioning left and right lead screws 6 have a left-hand lead screw section 7 located on the left side of the positioning platform 1 and a right-hand lead screw section 8 located on the right side of the positioning platform 1 and opposite 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 symmetrically arranged on the two positioning left and right nut seats 9 respectively. Positioning support wheels 11 located above the positioning support 3 are rotatably arranged on the inner end of the positioning support frame 10.

[0082] In this embodiment, multiple main positioning components arranged in a front-to-back direction can be set on the main vehicle body 24 to position workpiece one according to the length of workpiece one. Similarly, multiple secondary positioning components arranged in a front-to-back direction can be set on the secondary vehicle body 25 to position workpiece two according to the length of workpiece two.

[0083] 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.

[0084] The spacing between the two positioning support wheels 11 is controlled by the left and right lead screws 6, which avoids problems such as elastic fatigue and effectively improves service life and operational reliability. The rotatable design of the positioning support wheels 11 effectively reduces wear on the workpiece.

[0085] 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.

[0086] 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.

[0087] For structural optimization, preferably, the positioning seat 2 has a positioning port 47 extending through its left and right ends, and the positioning left and right lead screws 6 pass through the positioning port 247 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.

[0088] 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.

[0089] 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 via bearings. The two lead screw mounting seats 12 can also limit the extreme positions of the movement of the two left and right positioning nut seats 9.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] like Figure 13 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 47 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 screws 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.

[0094] Preferably, a positioning support shaft 55 is rotatably connected to the positioning support frame 10, and the positioning support wheel 11 is sleeved on the positioning support shaft 55.

[0095] A positioning locking gear 56 is connected to the positioning support shaft 55, and a plurality of locking grooves 57 are provided on the ring surface of the positioning locking gear 56.

[0096] The positioning support frame 10 is also slidably provided with a support wheel locking pin 58, the inner end of which can pass through the positioning support frame 10 and be inserted into the locking tooth groove 57.

[0097] In this embodiment, through the cooperation of the support wheel locking pin 58 and the locking gear 56, when the workpiece needs to be rotated slightly during the assembly process, the support wheel locking pin 58 can be slid to disengage it from the locking tooth groove 57, 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 57, which will lock the circumferential position of the locking gear 56, and thus lock the circumferential position of the positioning support wheel 11. The non-rotating positioning support wheel 11 can better position the workpiece.

[0098] like Figure 15 As shown, both the front and rear ends of the positioning support frame 10 are provided with locking pin holes 60 for the support wheel locking pin 58 to be inserted, so that the operator can lock the positioning support wheel 11 from both the front and rear sides. The support wheel locking pin 58 has a locking pin limiting section 59 with an outer diameter larger than the inner diameter of the locking pin hole 60, so as to prevent the support wheel locking pin 28 from moving excessively and damaging the positioning support wheel 11.

[0099] Since workpiece 1 and workpiece 2 are already assembled during the transfer, the positioning support frame 10 on the main positioning assembly is equipped with a support wheel locking pin 58 and a positioning locking gear 56 to perform circumferential positioning of workpiece 1. Similarly, the same effect can be achieved for workpiece 2.

[0100] Preferably, positioning scales 16 are provided at both the left and right ends of the positioning platform 1;

[0101] 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.

[0102] This embodiment is a manual operation of the main positioning component and the auxiliary positioning component. By setting the left and right positioning indicator 17 and the left and right positioning scale 16, the operator can easily know the displacement of the two positioning support wheels 11 to better position the workpiece.

[0103] Preferably, the secondary positioning component further includes a positioning support seat 18 connected to the secondary vehicle body 25, the positioning support seat 18 is provided with positioning upper and lower nut seats 19, and the bottom end of the positioning platform 1 of the secondary positioning component is provided with a positioning upper and lower lead screw 20 that can penetrate and cooperate with the positioning upper and lower nut seats 19.

[0104] In this embodiment, rotating the upper and lower positioning screws 20, through the cooperation of the upper and lower positioning screws 20 and the upper and lower positioning nut seats 19, allows the positioning platform 1 of the sub-positioning assembly to move up and down. When multiple sub-positioning assemblies are used to position the same workpiece 2, the height and position of each sub-positioning assembly can be adjusted independently to adapt to the shape of workpiece 2. In addition, the overall height or angle of workpiece 2 can be adjusted according to the height of workpiece 1 to meet assembly requirements.

[0105] 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.

[0106] Preferably, the positioning support 18 is further provided with a positioning upper and lower guide cylinder 22;

[0107] 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.

[0108] In this embodiment, the stability of the positioning stage 1 moving up and down in the sub-positioning assembly can be improved by the cooperation of the positioning guide rod 23 and the positioning guide cylinder 22.

[0109] Preferably, the main vehicle body 24 is provided with main positioning front and rear guide rails 38 arranged in a front-to-back direction, and the bottom end of the positioning platform 1 of each main positioning component is provided with a main positioning front and rear slider 39 that cooperates with the main positioning front and rear guide rails 38.

[0110] The sub-body 25 is provided with sub-positioning front and rear guide rails 40 arranged in a front-to-back direction, and the bottom end of the positioning support seat 18 of each sub-positioning component is provided with a sub-positioning front and rear slider 41 that cooperates with the sub-positioning front and rear guide rails 40.

[0111] In this embodiment, the cooperation of the main positioning front and rear guide rails 38 and the main positioning front and rear sliders 39 facilitates the manual movement of the spacing and position of each main positioning component on the main vehicle body 24 to better position workpiece one; the cooperation of the secondary positioning front and rear guide rails 40 and the secondary positioning front and rear sliders 41 facilitates the manual movement of the spacing and position of each secondary positioning component on the secondary vehicle body 25 to better position workpiece two.
