Description

Technical Field

[0001] The utility model relates to the field of automobile painting, in particular to a PVC hanger capable of carrying multiple platforms and multiple models. Background Art

[0002] In the field of motor vehicle processing, painting is a necessary production link in the production line. During painting, the car body needs to be transferred from the trolley to the PVC hanger, so that the car body is suspended in the air, and then the PVC base plate glue is sprayed on the lower part of the car body manually or by robots, and finally the car body is transferred to the next process. It can be seen that PVC hangers are important and indispensable equipment in motor vehicle painting workshops. Traditional PVC hangers mainly include frames and booms. The support blocks on existing booms are generally fixed structures, which makes them often suitable for mixed flow lifting of single models or a small number of models on the same platform; in addition, existing PVC hangers must first descend to a low position, and then the car body is moved to the top of the hanger for lifting, which increases the time for the car body to move to the lifting frame, and the generation cycle is relatively slow. Summary of the invention

[0003] In view of this, the utility model proposes a PVC hoist that can be carried on multiple platforms and multiple vehicle models, which is not only suitable for a variety of different vehicle models, but also improves the lifting efficiency of the vehicle body.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The PVC sling for carrying multiple platforms and multiple models of vehicles described in the utility model is arranged on a lifting frame, which includes a frame that is slidably matched with the lifting frame, and the PVC sling includes at least two pairs of boom assemblies symmetrically arranged on the frame, a power mechanism that drives each of the boom assemblies to rotate, a first support seat arranged on at least one pair of the boom assemblies, and a second support seat arranged on at least one pair of the boom assemblies;

[0006] The boom assembly includes a sleeve arranged on the frame and a boom with an L-shaped structure, the boom having a vertical section and a horizontal section, the first support seat or the second support seat is arranged at the end of the horizontal section; the upper part of the vertical section is rotatably arranged in the sleeve, and a connecting shaft with an L-shaped structure is arranged between the lower part of the vertical section and the horizontal section, and a transmission member connected to the power mechanism is arranged at the corner of the connecting shaft.

[0007] The beneficial effects are as follows: the arm of the utility model can rotate, and the rotation angle can be determined according to the actual vehicle model, thereby meeting the lifting requirements of different vehicle models and realizing flexible production; the utility model can run synchronously with the vehicle body, and when the previous hoist rises and rotates out, the vehicle body runs synchronously in place, and then the hoist falls to the vehicle body position with the arm folded, and then the power mechanism quickly rotates and opens the arm to hold the vehicle body for lifting, thereby improving work efficiency. Compared with traditional hoists, the utility model shortens the transfer lifting of each vehicle body to less than 84 seconds, and increases the number of transfer lifting units from 32 units / h to 43 units / h, thereby improving coating efficiency and accelerating the production cycle.

[0008] Preferably, the power mechanism is fixed on the ground of the lifting station, and has a fixed seat, a motor reducer arranged on the fixed seat, and a driving member driven by the motor reducer. The driving member has a limit slot that cooperates with the transmission member, so that the transmission member can be detachably mounted in the limit slot.

[0009] Preferably, the transmission member is a horizontally arranged transmission rod; the driving member is a petal-shaped driving block, which has two or more limit slots, and the two or more limit slots are arranged crosswise. The driving block of the present invention adopts a petal-shaped structure, which is convenient for connecting and separating with the transmission rod.

[0010] The boom assembly also has a guide assembly, which includes an upper guide member arranged at the lower part of the sleeve and a lower fixing member arranged at the upper part of the boom, the lower fixing member is provided with a guide rod, the upper guide member is provided with an arc hole matched with the guide rod, and the guide rod passes through the arc hole upward. When the boom rotates, the guide rod rotates along the arc hole, thereby improving the movement accuracy of the boom.

[0011] Compared with the prior art, the arm of the utility model can rotate, and the rotation angle can be determined according to the actual vehicle model, thereby meeting the lifting requirements of different vehicle models and realizing flexible production; the utility model can run synchronously with the vehicle body. When the previous hoist rises and rotates out, the vehicle body runs in place synchronously, and then the hoist falls to the vehicle body position with the arm folded, and then the power mechanism quickly rotates and opens the arm to support the vehicle body for lifting. Compared with traditional hoists, the utility model shortens the transfer lifting of each vehicle body to less than 84 seconds, and increases the number of transfer lifting units from 32 units / h to 43 units / h, improving the coating efficiency and speeding up the production cycle.

This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0023] It should be noted that, in the description of the present utility model, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] like Figure 1-2As shown, the PVC hanger for carrying multiple platforms and multiple models described in the utility model is slidably arranged on a lifting frame in a paint shop, and includes a frame 1 that is slidably matched with the lifting frame. The PVC hanger includes two pairs of boom assemblies 2 symmetrically arranged on the frame 1, a power mechanism 3 that drives each boom assembly 2 to rotate, a first support seat 4 arranged on one pair of boom assemblies 2 and a second support seat 5 arranged on the other pair of boom assemblies 2. The frame 1 is a rectangular structure, and the two pairs of boom assemblies 2 are symmetrically arranged at the ends of the long beam of the frame 1. Each boom assembly 2 includes a sleeve 2.1 vertically arranged on the long beam and a boom 2.2 with an L-shaped structure. The boom 2.2 has a vertical section and a horizontal section, and a first support seat 4 or a second support seat 5 for supporting a vehicle body is fixedly installed at the end of the horizontal section; the upper part of the vertical section is rotatably arranged in the sleeve 2.1, and a connecting shaft 2.3 with an L-shaped structure is arranged at the lower part of the vertical section, and a transmission member connected to the power mechanism 3 is arranged at the corner of the connecting shaft 2.3.

[0026] Combination Figure 2-5 It can be seen that the transmission member is a horizontally arranged transmission rod 2.4; Figure 6-7 It can be seen that the power mechanism 3 is installed on the ground of the lifting station. The power mechanism 3 includes a fixed seat 3.4, a motor reducer 3.1 arranged on the fixed seat 3.4, and a driving member driven by the motor reducer 3.1 (i.e. a driving block 3.2 of a petal-shaped structure). The driving block 3.2 is provided with two concentric and intersecting limit slots 3.3 (i.e. the driving block has two clamping positions, which realizes the rapid clamping of the transmission rod 2.4 and the limit slot 3.3, and facilitates the disengagement.

[0027] Combination Figure 1 It can be seen that the first support seat 4 has two first support heads and a second support head arranged at intervals, which are used to support the rear floor assembly; the second support seat 5 has multiple support heads, which act on the front part of the vehicle body. In actual use, the rotation angle can be adjusted to meet the support requirements of different models.

[0028] Combination Figure 2-5 It can be seen that each boom assembly 2 is also provided with a guide assembly, which includes an upper guide member (i.e., an upper guide block 6.1) provided at the lower part of the sleeve 2.1 and a lower fixing member (i.e., a lower fixing block 6.2) provided at the upper part of the boom 2.2. A vertical guide rod 6.3 is provided on the lower fixing block 6.2, and an arc hole 6.4 is provided on the upper guide block 6.1 to cooperate with the guide rod 6.3, and the guide rod 6.3 passes through the arc hole 6.4 upward. When the boom 2.2 rotates, the guide rod 6.3 rotates along the arc hole 6.4, thereby improving the rotation accuracy of the boom 2.2.

[0029] Combination Figure 2-5It can be seen that the upper part of the guide rod 6.3 is provided with a positioning pin 6.6 connected by a connecting piece 6.5, and the positioning pin 6.6 is located on the outer side of the upper guide block 6.1. A positioning hole 6.7 cooperating with the positioning pin 6.6 is provided at the edge of the upper guide block 6.1, and the lower part of the positioning pin 6.6 is a conical structure. When the positioning pin 6.6 is located in the positioning hole 6.7, the boom 2.2 is in the initial state; after the sling is lowered into place, the frame 1 and the sleeve 2.1 move slightly downward under the action of gravity, and the boom 2.2 is clamped on the driving block 3.2 through the transmission rod 2.4 at its bottom. After the sling is in place, the height of the boom 2.2 remains unchanged, so that the spacing between the positioning pin 6.6 and the upper guide block 6.1 becomes larger. Since the lower part of the positioning pin 6.6 is a conical structure, the positioning pin 6.6 is disengaged from the positioning hole. At this time, the power mechanism can be used to rotate the boom 2.2. The positioning pin 6.6 and the positioning hole 6.7 further improve the rotation accuracy of the boom.

[0030] The action process of the flexible PVC hanger of the present invention is as follows: when the present invention is lowered into place, the transmission rods 2.4 are clamped in the corresponding limit slots one by one, and the four motor reducers 3.1 (which can be started simultaneously or individually) respectively drive the suspension arm 2.2 to rotate, so that the first support seat 4 and the second support seat 5 rotate to the bottom of the frame 1. This state is recorded as the support state. Figure 8 When the boom 2.2 rotates in the opposite direction, so that the boom 2.2 and its support seat are located below the long beam of the frame 1, this state is recorded as the stowed state, see Fig. 9 When the spreader is in the stowed position, it can pass through the vehicle body from top to bottom.

[0031] In order to improve the coating efficiency, multiple PVC hoists are installed in the PVC line of the coating workshop. Transfer stations are set at the entrance and exit of the PVC line. Each transfer station has multiple power mechanisms 3 corresponding to the upper and lower boom assemblies 2. After the hoist is in place, the power mechanism 3 can be used to adjust the hoist arm to an open state, so that the hoist can lift the car body and lift it to the working layer through the elevator and move it to the next process; each transfer station is equipped with an elevator to realize the lifting of the hoist and / or the car body. The specific process is as follows:

[0032] Combination Fig.10 It can be seen that the PVC lifting device (the boom is in the retracted state, see Fig. 9 ) moves downward, and the car body moves synchronously to the transfer station at the entrance. After the car body is in place, the PVC hanger passes through the car body from top to bottom and each transmission rod 2.4 of the hanger is correspondingly mounted in the limit slot below. The motor reducer 3.1 drives the arm 2.2 to rotate through the transmission rod 2.4, so that the first support seat 4 and the second support seat 5 rotate to the bottom of the car body, and the hanger and the car body are lifted to the working layer by the elevator (see the support of the hanger and the car body). Figure 8), the PVC spreader supports the vehicle body to move on the working layer for PVC coating operation, while the entrance elevator rises to the empty spreader layer to prepare for the next spreader;

[0033] When the PVC coating operation is completed, the sling moves with the car body to the transfer station at the exit, and the elevator at the station drives the PVC sling and the car body to move downward. After the sling is lowered into place and the car body falls onto the corresponding trolley, the motor reducer is started to put the sling in the retracted state. The painted car body moves to the next process with the trolley, and the sling is sent to the empty sling storage layer by the elevator at the exit;

[0034] In the utility model, since there are multiple hoists, when the car body at the transfer station at the entrance is lifted to the working layer, the entrance elevator drives the second hoist down to support the second car body. When the second car body is supported to the working layer, the entrance elevator drives the third hoist from top to bottom to support the third car body, thereby realizing the assembly line transfer and painting of the car body, thereby improving the painting efficiency.

[0035] The rotation angle of the boom 2.2 in the utility model can be determined according to actual needs, so as to adapt to the lifting of different models; the PVC hoist of the utility model can run synchronously with the car body. When the previous hoist rises and rotates out, the car body runs synchronously in place, and then the hoist falls to the car body position with the boom 2.2 folded, and then the power mechanism 3 quickly rotates and opens the boom 2.2 to hold the car body for lifting, thereby improving work efficiency. Compared with the traditional lifting method, the utility model shortens the transfer lifting of each car body to less than 84 seconds, and increases the number of transfer lifting units from 32 units / h to 43 units / h, thereby improving coating efficiency and accelerating the production cycle.

[0036] Finally, it should be emphasized that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions recorded in the aforementioned embodiments without creative labor, or to replace some of the technical features therein by equivalents. Therefore, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the utility model.
