Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling change equipment technology, and in particular to a tooling change device. Background Technology
[0002] Tooling changeover platforms play a crucial role in the automotive welding production process, serving as a key component for enabling the production of different vehicle models on the same production line. When the production line is producing vehicle model A, tool A is placed on the platform; when the production line switches to producing vehicle model B, tool A is removed from the platform, and tool B is placed on it. Existing tooling changeover platforms mainly consist of support plates, guide plates, connecting bolts, and locating pin holes. During tooling changeover, a forklift is used to place the tooling onto the support plate. Once the tooling is in place, the locating pins precisely position the tooling and the changeover platform, which is then secured by hinge bolts.
[0003] In the existing solution, during the tooling change process, after the tooling is placed on the support plate, there is sliding friction between the support plate and the tooling. It is difficult to manually push the tooling to find the right pin hole, making the pushing operation difficult, and the changeover time is long, resulting in low changeover efficiency. Utility Model Content
[0004] In view of this, the present invention aims to provide a tooling change device to facilitate tooling change.
[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:
[0006] A tooling changeover device includes a base, a support portion and a first drive portion disposed on the base;
[0007] The base has a support surface for supporting the tooling, and the support part includes a support platform that is slidably disposed on the base in a vertical direction, and a rolling element that protrudes outward from the top of the support platform.
[0008] The first driving part is located below the support part, and the first driving part can drive the support part to rise and make the rolling element protrude from the support surface to abut against the tooling.
[0009] Furthermore, the base is provided with a limiting structure, which defines the placement position of the tooling on the base;
[0010] The limiting structure includes a first limiting part and a second limiting part. The first limiting part is used to limit the position of the tooling in a first direction, and the second limiting part is used to limit the sliding displacement of the tooling in a second direction. The first direction, the second direction and the vertical direction are perpendicular to each other.
[0011] Furthermore, the first limiting part includes a limiting groove provided on the base, the limiting groove extending along the second direction;
[0012] The tooling is equipped with a guide plate, which can be inserted into the limiting groove and slide along the limiting groove.
[0013] Furthermore, the base is rotatably provided with cylinders located on two opposite sides of the limiting groove, and the cylinders on both sides abut against the guide plate and limit the position of the guide plate in the first direction.
[0014] Furthermore, the second limiting part includes a limiting block disposed on the base, and the limiting block is located at the front end of the limiting groove along the sliding direction of the tooling.
[0015] Furthermore, the base is provided with a positioning part, which is used to position the tooling at the placement position.
[0016] Furthermore, the positioning part includes a second driving part disposed on the base, and a positioning column disposed at the power output end of the second driving part;
[0017] The second drive unit can drive the positioning column to rise and fall to insert or disengage from the positioning hole of the tooling.
[0018] Furthermore, the base is provided with a third drive unit and a quick-connect duct plug located at the power output end of the third drive unit.
[0019] The third driving unit can drive the tracheal quick-connect plug to approach the tooling along the first direction and mate with the connector of the tooling.
[0020] Furthermore, the first drive unit includes an airbag connected to an external air source; and / or,
[0021] The support platform is a long strip extending along the second direction, and the rolling elements are a plurality of elements spaced apart along the length of the support platform.
[0022] Furthermore, the base is provided with a locking part, which is used to lock the tooling onto the base.
[0023] Compared with the prior art, this utility model has the following advantages:
[0024] The tooling changeover device of this invention, by providing a support portion with rolling elements and a first driving portion capable of driving the support portion upward, enables rolling friction to be generated between the rolling elements and the tooling during the changeover process, utilizing the rolling characteristics of the rolling elements. This reduces the frictional force of the tooling during movement or adjustment, facilitating tooling changeover operations. Simultaneously, frequent changeover operations can easily cause scratches and wear on the tooling surface, while rolling friction can significantly reduce the degree of wear and extend the tooling's service life. Furthermore, after changeover, the driving force of the first driving portion on the support portion can be removed, allowing the tooling to settle on the support surface, thus providing good installation stability.
[0025] Furthermore, by setting a limiting structure on the base to define the placement position of the tooling, the tooling can be quickly and accurately placed in the correct position without the need for complex measurement and adjustment processes, reducing operational difficulty and improving changeover efficiency. The first limiting part includes a limiting groove on the base and a guide plate on the tooling that can be inserted into the limiting groove. This design is not only simple in structure and easy to manufacture, but also allows the operator to simply align the guide plate of the tooling with the limiting groove, insert it, and then slide it along the limiting groove to complete the positioning of the tooling in the first direction. This reduces operational difficulty and improves changeover efficiency.
[0026] By providing cylinders on two opposite sides of the limiting groove on the base, and making the guide plate abut against the two opposite cylinders, the cylinders have the characteristic of being able to rotate flexibly. During the sliding process of the guide plate along the limiting groove, the contact between the guide plate and the cylinders is a rolling contact, which can significantly reduce the friction of the guide plate during the sliding process, making the operation easier and less strenuous. At the same time, the smaller friction can reduce the wear on the surface of the guide plate and extend the service life of the tooling.
[0027] Secondly, the second limiting part includes a limiting block located at the end of the limiting groove, which provides physical obstruction and precise limiting, resulting in a good limiting effect. Furthermore, it has a simple structure and is easy to manufacture. By providing a positioning part on the base, the tooling in the placement position can be prevented from shaking and deviating, thereby ensuring that the tooling is accurately positioned in the predetermined location in three-dimensional space.
[0028] The positioning unit includes a second drive unit mounted on the base and a positioning column mounted on the power output end of the second drive unit. Thus, by simply driving the positioning column to rise or fall, the positioning of the tooling can be completed or released. Operators do not need to perform complex positioning operations manually. They only need to control the movement of the second drive unit. This simplifies the tooling changeover process, improves the efficiency of changeover, and reduces problems that may be caused by inaccurate manual positioning.
[0029] Furthermore, by setting up a third drive unit and a quick-connect air hose plug at the power output end of the third drive unit, it is easy to connect the tooling to an external air source. Compared with the manual plugging and unplugging method, the automatic drive unit drives the plug to approach the tooling connector for docking, which can greatly save connection time and improve the overall efficiency of tooling changeover.
[0030] Furthermore, the first drive unit includes an airbag connected to an external air source. Because the airbag can provide a relatively uniform pressure distribution, it can ensure that all parts of the support unit receive a relatively balanced force during the upward movement of the tooling, which helps maintain the stability of the tooling's upward movement and is also cost-effective. The multiple rolling elements can share the weight of the tooling, helping to reduce excessive local pressure. By incorporating a locking mechanism, the tooling's position on the base is kept fixed, preventing deviations in the production process caused by minor movements of the tooling.

Therefore, they should not be construed as limitations on this utility model.

[0052] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.
[0053] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0054] Given the following problems with existing tooling changeover devices, during the tooling changeover process, after the tooling is placed on the support plate, there is sliding friction between the support plate and the tooling. Manually pushing the tooling to align the pin holes is difficult, making the pushing operation challenging, and the changeover time is long, resulting in low efficiency. Therefore, this embodiment proposes a novel tooling changeover device, including a base 1, a support portion 2, and a first driving portion disposed on the base 1.
[0055] The base 1 has a support surface M for supporting the tooling. The support part 2 includes a support platform 202 that slides vertically on the base 1 and a rolling element disposed on the top of the support platform 202. The first drive part is disposed below the support part 2 and can drive the support part 2 to rise and cause the rolling element to protrude from the support surface M to abut against the tooling.
[0056] The tooling changeover device of this embodiment, by providing a support portion 2 with rolling elements and a first driving portion capable of driving the support portion 2 upward, enables rolling friction to be generated between the rolling elements and the tooling during the changeover process, utilizing the rolling characteristics of the rolling elements. This reduces the frictional force of the tooling during movement or adjustment, facilitating tooling changeover operations. Furthermore, frequent changeover operations can easily cause scratches and wear on the tooling surface, while rolling friction can significantly reduce the degree of wear and extend the tooling's service life. In addition, after changeover, the driving force of the first driving portion on the support portion 2 can be removed, allowing the tooling to settle on the support surface M, thus providing better installation stability.
[0057] Based on the above overview, an exemplary structure of the tooling changeover device in this embodiment is described below. Figures 1 to 3 As shown in the figure, to improve the usage effect, the tooling changer in this embodiment has two tooling change stations, so that two tooling changers can be performed simultaneously, and the two tooling change stations have the same structure. The following describes the process in conjunction with... Figures 4 to 7 The illustration shown uses only one workstation as an example. It is understandable that this tooling changeover device, in addition to having… Figure 1The two changeover stations shown can also be configured with only one changeover station, or multiple changeover stations. The tooling can be of different types depending on the usage requirements, such as welding tooling or other tooling. Therefore, the tooling will not be described in detail here, as long as it has the structure described below that is compatible with this device.
[0058] As a specific embodiment, combined with Figure 4 and Figure 5 As shown, the support surface M in this embodiment is a rectangular surface extending in the left-right direction. Here, the structure of the base 1 is not specifically limited, as long as it has the support surface M. In order to improve the support effect on the tooling, as a further embodiment, the support platform 202 is an elongated strip extending along the width direction (i.e., the second direction described below) of the support surface M, and the rolling elements are a plurality of elements spaced apart along the length direction of the support platform 202. The arrangement of these plurality of rolling elements allows them to jointly bear the weight of the tooling, which helps to reduce excessive local pressure.
[0059] In addition, such as Figure 5 As shown in the diagram, in a preferred embodiment, the support portion 2 and the first driving portion are respectively arranged in two spaced-apart configurations along the length of the support surface M. Of course, it is feasible to have more spaced-apart support portions 2 and the first driving portion, or even just one support portion 2 and one first driving portion. However, when the area of the tooling is large, this would obviously reduce the stability of the tooling. Specifically, as... Figure 6 As shown, a cavity for accommodating the support part 2 and the first drive part is provided on the base 1. In a preferred embodiment, the first drive part of this embodiment includes an airbag 201 connected to an external air source.
[0060] Because the airbag 201 can provide a relatively uniform pressure distribution, during the process of pushing the support 2 upward, it can ensure that all parts of the support 2 are subjected to a relatively balanced force, which is beneficial to maintaining the stability of the tooling's upward movement. Moreover, the cost is relatively low. Furthermore, the airbag 201 generally extends along the length of the support platform 202, thereby providing more stable support for the tooling. It should be noted that, in addition to the airbag 201, the first drive unit can also include a linear motor or linear cylinder connected to the support platform 202. In this case, to improve the support effect, it is preferable to use multiple linear motors or linear cylinders spaced apart. This structure, compared to the structure using the airbag 201, obviously increases manufacturing costs and debugging difficulty.
[0061] In addition, such as Figure 6As shown in the figure, to improve the smoothness of the lifting of the support platform 202, the side walls on both sides of the support platform 202 are abutted against the side walls of the accommodation cavity to guide the lifting of the support platform 202. At this time, since the first driving part includes an airbag 201, the support platform 202 can be directly placed on the airbag 201. At this time, to prevent the support platform 202 from slipping out of the accommodation cavity due to lifting, as a preferred embodiment, as Figure 6 As shown in the figure, the cross-section of the support platform 202 is generally in a "convex" shape, and a cover plate 101 that blocks the top of the accommodation cavity is provided on the base 1 to limit the support platform 202 from slipping out of the accommodation cavity. Among them, the rolling elements can specifically adopt rolling balls 203, and the above-mentioned rolling elements protrude outwards from the top of the support platform 202. That is to say, the rolling balls 203 protrude upwards relative to the top of the support platform 202 to be able to abut against the tooling. Moreover, the rolling balls 203 are constrained in the support platform 202 and can rotate relative to the support platform 202.
[0062] In this embodiment, as a further implementation method, a limiting structure is provided on the base 1, and the limiting structure defines the placement position of the tooling on the base 1. And the limiting structure includes a first limiting part and a second limiting part. The first limiting part is used to limit the position of the tooling in the first direction, and the second limiting part is used to limit the sliding displacement of the tooling in the second direction, and the first direction, the second direction and the vertical direction are perpendicular to each other in pairs. Among them, based on the state shown in the figure, the first direction is the left-right direction, that is, the length direction of the support surface M, the second direction is the front-back direction, that is, the width direction of the support surface M, and the vertical direction is the direction perpendicular to the support surface M.
[0063] By setting the limiting structure, the positions of the tooling in the two horizontal directions can be accurately limited, avoiding possible position errors of the tooling in these two directions. Thus, the tooling can be quickly and accurately placed in the correct position according to the limiting structure, without a complex measurement and adjustment process, reducing the operation difficulty and improving the changeover efficiency.
[0064] As a preferred embodiment, as Figure 5 and Figure 7 As shown in the figure, the first limiting part includes a limiting groove 3 provided on the base 1, and the limiting groove 3 extends along the second direction. At the same time, a guide plate is provided on the tooling, and the guide plate can be inserted into the limiting groove 3 and slide along the limiting groove 3. The first limiting part of this embodiment includes a limiting groove 3 provided on the base and a guide plate that can be inserted into the limiting groove 3 is provided on the tooling. It not only has a simple structure and is easy to process and manufacture. Moreover, the operator only needs to align the guide plate of the tooling with the limiting groove 3 and insert it, and then slide along the limiting groove 3 to complete the positioning of the tooling in the first direction, with a relatively low operation difficulty and can improve the changeover efficiency.
[0065] Among them, as Figure 5As shown in the diagram, in a preferred embodiment, the limiting groove 3 is located between the two support portions 2 to provide better limiting and guiding effects. (Continuing to refer to...) Figure 5 and Figure 7 As shown in the figure, as a further embodiment, the base 1 is rotatably provided with cylinders located on two opposite sides of the limiting groove 3, and the cylinders on both sides abut against the guide plate and limit the position of the guide plate in the first direction.
[0066] Because the cylinder itself has the characteristic of flexible rotation, the contact between the guide plate and the cylinder is rolling contact during the sliding process of the guide plate along the limiting groove 3. This setting can significantly reduce the friction of the guide plate during the sliding process. Compared with simple surface-to-surface contact sliding (if there is no cylinder), the coefficient of friction of rolling friction is much smaller. Therefore, when changing tooling, the external force required to push the guide plate to slide along the limiting groove 3 can be reduced, making the operation easier and less strenuous, which helps to improve the efficiency of tooling change, especially when tooling changes are frequent, this advantage will be more obvious.
[0067] Furthermore, lower friction reduces wear on the guide plate surface. During long-term tooling changeovers, higher friction can easily cause wear on the guide plate and the contacting limiting groove 3, leading to decreased guiding accuracy and poor fit. Rolling contact significantly reduces wear on the guide plate, extending the overall service life of the tooling and reducing maintenance and replacement costs. In one preferred embodiment, two opposing cylinders are arranged opposite each other in a first direction, and are spaced apart along a second direction.
[0068] Furthermore, as a specific embodiment, the cylinder is formed by the outer ring of the cam-type needle roller bearing 4 mounted on the base 1. Of course, besides being formed by the outer ring of the cam-type needle roller bearing 4, the cylinder can also be a solid or hollow cylindrical structure rotatably mounted on the base 1. Alternatively, a structure consisting of a deep groove ball bearing and a connecting shaft is also feasible. The guide plate on the tooling is designed to fit the limiting groove 3 and abut against the cylinders on both sides.
[0069] In this embodiment, as Figure 3 As shown in the illustration, in one specific embodiment, the second limiting part includes a limiting block 5 disposed on the base 1, and the limiting block 5 is located at the front end of the limiting groove 3 along the sliding direction of the tooling. Therefore, as the tooling moves, once the tooling contacts the limiting block 5, it will prevent the tooling from continuing to slide in that direction, thereby effectively limiting the maximum sliding displacement of the tooling in the second direction, ensuring that the tooling will not deviate from the preset correct position due to excessive sliding, and achieving precise positioning of the tooling in the second direction. Moreover, the limiting block 5 has a simple structure and is easy to manufacture. Furthermore, to further improve the limiting effect, such as... Figure 3As shown, there are two limit blocks 5 located at both ends of the base 1. Of course, in addition to setting two limit blocks 5, it is also feasible to set more limit blocks 5.
[0070] As a further embodiment, the base 1 is provided with a positioning part 6, which is used to position the tooling in the placement position. By providing the positioning part 6 on the base 1, the tooling in the placement position can be prevented from shaking and deviating, thereby ensuring that the tooling is accurately positioned in the predetermined placement position in three-dimensional space. In a preferred embodiment, the positioning part 6 includes a second driving part provided on the base 1 and a positioning pin 62 provided at the power output end of the second driving part. Furthermore, the second driving part can drive the positioning pin 62 to rise and fall to insert or disengage from the positioning hole of the tooling.
[0071] Therefore, when tooling needs to be positioned, the drive positioning pin 62 rises, inserting it into the positioning hole of the tooling to be replaced. Since the position of the positioning hole is fixed and related to the overall design position of the tooling, once the positioning pin 62 is inserted, it restricts the movement of the tooling from a specific point, thus achieving precise positioning of the tooling at that location. Conversely, when tooling needs to be replaced or positioning needs to be released, the second drive unit drives the positioning pin 62 downwards, disengaging it from the positioning hole, allowing the tooling to proceed with subsequent operations. Furthermore, the second drive unit eliminates the need for operators to perform complex manual positioning operations. By controlling the action of the second drive unit (such as button operation), the alignment of the positioning pin 62 with the positioning hole can be completed, simplifying the tooling changeover process, improving changeover efficiency, and reducing problems that may arise from inaccurate manual positioning.
[0072] As a specific embodiment, combined with Figure 4 , Figures 8 to 10 As shown in the diagram, the second driving unit in this embodiment is specifically a first cylinder 61 disposed vertically on the base 1. To accommodate the first cylinder 61, a corner seat 601 and an L-shaped mounting base 602 are provided on the base 1. The first cylinder 61 is specifically disposed on the transverse portion of the mounting base 602, and the positioning post 62 is specifically disposed on the driving end of the first cylinder 61. Furthermore, to further improve the positioning effect, a guide unit is provided to guide the lifting and lowering of the positioning post 62. Wherein, as... Figure 10 As shown in the illustration, in one specific embodiment, the guide portion includes a guide cylinder 605 disposed on the vertical portion of the mounting base 602, and a guide post 63 disposed on the drive end of the first cylinder 61.
[0073] Furthermore, the guide post 63 is slidably inserted into the guide cylinder 605, and the positioning post 62 is specifically disposed on the guide post 63. Thus, the positioning post 62 can be guided by the contact between the guide post 63 and the guide cylinder 605. In addition, as a specific embodiment, such as... Figure 10 As shown, a mounting cylinder 603 is provided on the vertical portion of the mounting base 602, and a guide cylinder 605 is specifically inserted into the mounting cylinder 603. Furthermore, to prevent the guide cylinder 605 from dislodging from the mounting cylinder 603 when the positioning post 62 rises, as shown... Figure 10 As shown, a limiting plate 604 is provided at the top of the mounting cylinder 603.
[0074] In addition, as a further embodiment, the base 1 is provided with a third drive unit and an air tube quick-connect plug 9 located at the power output end of the third drive unit. Furthermore, the third drive unit can drive the air tube quick-connect plug 9 to approach the tooling along a first direction and mate with the tooling connector. By providing the third drive unit and the air tube quick-connect plug 9, a highly efficient tooling connection process can be achieved. Compared to the traditional manual plugging and unplugging method, automatically driving the plug to approach the tooling connector for mating by the third drive unit can greatly save connection time and improve the overall efficiency of tooling changeover. At the same time, it reduces the possibility of misalignment between the plug and connector due to manual operation, improving the accuracy and reliability of the mating.
[0075] In this embodiment, the third driving unit is specifically a second cylinder 7, and the second cylinder 7 is specifically disposed on the base 1 along the first direction. To facilitate the installation of the quick-connect air pipe 9, such as... Figure 11 As shown, a mounting plate 701 is provided at the drive end of the second cylinder 7, and the quick-connect pipe 9 is mounted on the mounting plate 701 and connected to an external air source. In addition, to improve the docking effect, two guide rods 702 are arranged opposite each other on the mounting plate 701, and correspondingly, guide holes are provided on the tooling. Thus, the second cylinder 7 can drive the mounting plate 701 closer to the tooling, first inserting the guide rods 702 into the guide holes, and then docking the quick-connect pipe 9 with the tooling connector, thereby connecting the tooling to the external air source. In specific implementations, the quick-connect pipe 9 can use an existing structure.
[0076] Furthermore, as a further embodiment, the base 1 is provided with a locking part 8, which is used to lock the tooling onto the base 1. By providing the locking part 8, it is beneficial to ensure that the position of the tooling on the base 1 remains fixed, avoiding deviations in the production process due to slight movements of the tooling position. As a specific embodiment, such as... Figure 5 As shown, the locking part 8 in this embodiment includes two locking holes 801 at both ends of the base 1, so that a pin inserted on the tooling can be inserted into the locking holes 801 to fix the tooling in the placement position. Alternatively, the locking part 8 may also include bolt holes on the base 1 and be connected to the tooling by bolts, so that the tooling can also be fixed in the placement position.
[0077] Based on the above overview, in use, the tooling changing device of this embodiment first uses a lifting vehicle to push the tooling to the front of the base 1, ensuring it is at the same height as the support surface M of the base 1. Then, the airbag 201 is inflated. During inflation, the airbag 201 compresses the support platform 202 and the rolling ball 203 above it, causing them to move upwards until they contact the lower surface of the cover plate 101. At this point, the rolling ball 203 is higher than the support surface M, allowing the tooling to slide on it. Simultaneously, the guide plate below the tooling enters between the two rows of cam needle roller bearings 4 and pushes forward along the two rows of cam needle roller bearings 415 (limiting the tooling's displacement in the first direction) and stops after contacting the limiting block 5 (limiting the tooling's displacement in the second direction).
[0078] Then, the first cylinder 61 is extended, driving the positioning pin 62 into the positioning hole of the tooling, locking the tooling in the first and second directions. Next, the airbag 201 is deflated. During the deflation process, the support platform 202 and the rolling ball 203 above it move downwards until the rolling ball 203 is below the support surface M, and the tooling contacts the support surface M, thus positioning the tooling vertically. It is then locked using a pin or bolt, completing the tooling switch. Then, the second cylinder 7 is driven to engage the quick-connect air pipe plug 9 with the tooling connector, achieving the switching of the air path on the tooling.
[0079] The tooling change device of this embodiment can utilize the rolling characteristics of the rolling elements to generate rolling friction between the rolling elements and the tooling during the change process, thereby reducing the friction force of the tooling during movement or adjustment, which is beneficial to the tooling change operation; at the same time, rolling friction can significantly reduce the degree of wear and extend the service life of the tooling.
[0080] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
