Description

Technical Field

[0001] The present disclosure relates to the technical field of mechanical tooling, and more particularly to a pressing and positioning device suitable for automotive parts. Background Art

[0002] Currently, in industrial production, when positioning a workpiece or combining it with other workpieces, a pressing mechanism is required to press or clamp the workpiece.

[0003] Common pressing mechanisms include components such as a pressure actuator and a pressure driving source. When in use, the pressure actuator actuates under the drive of the pressure driving source and presses the workpiece.

[0004] However, in the pressing mechanism, the pressure driving source and the pressure actuator are in the same direction, that is, the pressure driving source and the pressure actuator use a direct push method to achieve the clamping operation. However, after the pressure driving source pushes the pressure actuator in place, a certain thrust still needs to be maintained for the clamping operation. If the pressure output by the pressure driving source is too large, it is easy to damage the workpiece. In addition, the direct push type pressing mechanism will make the entire pressing mechanism longer. When the working space is narrow and limited, when the operator uses the pressing mechanism to position and clamp the workpiece, when the operator opens the pressing mechanism, problems such as the pressing mechanism being unable to be placed or other interferences will be encountered, and the workpiece cannot be effectively positioned and clamped.

[0033] In a pressing mechanism related to automotive parts, the pressure driving source and the pressure actuator adopt a direct pushing method to achieve the clamping operation. The direct pushing type pressing mechanism will make the entire pressing mechanism have a relatively large length, making it difficult to be applied to scenarios with a narrow working space, unable to effectively position and clamp the workpiece. In addition, in the direct pushing type pressing mechanism, the pressure driving source may damage the workpiece due to excessive output pressure. In view of this, the embodiments of the present disclosure provide a pressing and positioning device suitable for automotive parts.

[0034] The present disclosure provides a pressing and positioning device, including: a base, and a driving component and a pressing component arranged on the base. The driving component includes a pressure driving source, a force applying member, and a pressure executing member. The pressure executing member moves along a first direction under the drive of the pressure driving source. The pressing component includes a moving mounting member and a pressing member. The pressing member is associated with the pressure executing member of the driving component and moves relative to the moving mounting member along a second direction under the drive of the pressure executing member to press the workpiece.

[0035] Please refer to Figure 1 and Figure 2 , wherein, Figure 1 shows a three-dimensional schematic diagram of the pressing and positioning device in a certain perspective in an embodiment of the present disclosure, Figure 2 shows as Figure 1 the top view of the pressing and positioning device in

[0036] Combined with Figure 1 and Figure 2 , the pressing and positioning device may specifically include: a base 11, a driving component 12, and a pressing component 13.

[0037] The base 11 serves as the main component of the pressing and positioning device and is used to install the platform. In one example, the base 11 has a relatively large volume and weight to provide a larger installation surface and a more stable overall machine stability. As Figure 1 shown, the base 11 is a rectangular structure. It should be understood that the specific structure and shape of the base 11 can be changed based on different functional requirements or structural requirements.

[0038] In addition, corresponding installation structures may be provided on the base 11 for assembling the driving component 12 and the pressing component 13. Exemplarily, the installation structure may be, for example, an installation platform, and corresponding installation holes and the like may be provided on the installation platform.

[0039] The driving component 12 is arranged on the base 11 and is used to generate a driving force.

[0040] The driving assembly 12 further includes a pressure driving source 121, a force applying member 123, and a pressure executing member 125. By the action of the force applying member 123 on the pressure driving source 121, the pressure driving source 121 drives the pressure executing member 125 to move. In this embodiment, the pressure executing member 125 moves along the first direction under the drive of the pressure driving source 121.

[0041] In some embodiments, the driving assembly 12 may be, for example, a cylinder assembly. That is, the pressure driving source 121 is a cylinder, and the pressure executing member 125 is a cylinder output shaft. By the action of the force applying member 123 on the cylinder, the cylinder output shaft moves along the first direction under the drive of the cylinder. In some embodiments, the force applying member 123 may be an electric control pump to control the cylinder in an electric control manner. In some embodiments, the force applying member 123 may be a handle, and the cylinder is controlled by operating the handle. As Figure 1 and Figure 2 shown, in the following description, the cylinder may be labeled as 121, the handle may be labeled as 123, and the cylinder output shaft may be labeled as 125.

[0042] In some embodiments, the driving assembly 12 may be, for example, an oil cylinder assembly. That is, the pressure driving source 121 is an oil cylinder, and the pressure executing member 125 is an oil cylinder output shaft. By the action of the force applying member 123 on the oil cylinder, the oil cylinder output shaft moves along the first direction under the drive of the oil cylinder. In some embodiments, the force applying member 123 may be an electric control pump to control the oil cylinder in an electric control manner. In some embodiments, the force applying member 123 may be a handle, and the oil cylinder is controlled by operating the handle. As Figure 1 and Figure 2 shown, in the following description, the oil cylinder may be labeled as 121, the handle may be labeled as 123, and the oil cylinder output shaft may be labeled as 125.

[0043] Taking the force applying member 123 as a handle as an example, as Figure 1 and Figure 2 shown, the handle 123 is connected to the cylinder or oil cylinder 121 through a hinge assembly 122.

[0044] Please refer to Figure 3 , shown as Figure 1 the side view of the clamping and positioning device. Combining Figures 1 to 3The hinge assembly 122 includes a first connecting member 1221 and a second connecting member 1223. The first end of the first connecting member 1221 is fixedly arranged on the cylinder or oil cylinder 121 through a connecting block or a connecting plate 1225. The second end of the first connecting member 1221 is rotatably connected to the handle 123 through a first hinge pin 1222 (the handle 123 is correspondingly provided with a first hinge pin hole or a first hinge pin groove 1231). The first end of the second connecting member 1223 is rotatably connected to the cylinder or oil cylinder 121. The piston is connected, and the second end of the second connecting member 1223 is rotatably connected to the handle 123 through a second hinge pin 1224 (the handle 123 is correspondingly provided with a second hinge pin hole or a second hinge pin groove), wherein the rotationally connected part of the handle 123 with the first connecting member 1221 can be called a first connecting end, and the rotationally connected part of the handle 123 with the second connecting member 1223 can be called a second connecting end, and the first connecting end is located between the gripping portion of the handle 123 and the second connecting end.

[0045] In addition, the first hinge pin hole or the first hinge pin slot 1231 of the handle 123 corresponding to the first hinge pin 1222 is larger than the first hinge pin 1222, so as to provide a certain amount of redundant movement when the handle 123 rotates. Exemplarily, the first hinge pin hole is an oblong hole or a rectangular hole, so as to provide a redundant movement along the length direction of the handle. Alternatively, exemplarily, the first hinge pin slot is an elongated slot, so as to provide a redundant movement along the length direction of the handle.

[0046] When implemented as Figures 1 to 3 When the driving assembly 12 is shown, the operator operates the handle 123. After the handle 123 is subjected to force, it rotates with the first connecting member 1221 in the hinge assembly 122 as a fulcrum (that is, the first connecting end of the handle 123). The second connecting end of the handle 123 drives the piston of the cylinder or oil cylinder 121 through the second connecting member 1223, so that the cylinder output shaft or the oil cylinder output shaft 125 extends outward along the first direction or retracts inward along the first direction.

[0047] See also Figure 4 , which is a side view of a clamping and positioning device in another embodiment of the present disclosure. Figure 4 As shown,

[0048] The hinge assembly 124 includes a first connecting member 1241 and a second connecting member 1243, wherein the first end of the first connecting member 1241 is fixedly arranged on the air cylinder or oil cylinder 121 through a connecting block or a connecting plate 1245, the second end of the first connecting member 1241 is rotatably connected to the handle 123 through a first hinge pin 1242 (the handle 123 is correspondingly provided with a first hinge pin hole), the first end of the second connecting member 1243 is connected to the piston of the air cylinder or oil cylinder 121, and the second end of the second connecting member 1243 is rotatably connected to the handle 123 through a second hinge pin 1244 (the handle 123 is correspondingly provided with a second hinge pin hole 1232), wherein the rotationally connected portion of the handle 123 with the first connecting member 1241 can be referred to as a first connecting end, and the rotationally connected portion of the handle 123 with the second connecting member 1243 can be referred to as a second connecting end, and the second connecting end is located between the gripping portion of the handle 123 and the first connecting end.

[0049] In addition, the second hinge pin hole or second hinge pin slot 1232 of the handle 123 corresponding to the second hinge pin 1244 is larger than the second hinge pin 1244, so as to provide a certain amount of redundant movement when the handle 123 is rotated. Exemplarily, the second hinge pin hole 1232 is an oblong hole or a rectangular hole, so as to provide a redundant movement along the length direction of the handle. Alternatively, exemplarily, the second hinge pin slot 1232 is a long strip slot, so as to provide a redundant movement along the length direction of the handle.

[0050] When implemented as Figure 4 When the driving assembly 12 is shown, the operator operates the handle 123. After the handle 123 is subjected to force, it rotates with the first connecting member 1241 in the hinge assembly 124 as a fulcrum (that is, the first connecting end of the handle 123). The second connecting end of the handle 123 drives the piston of the cylinder or oil cylinder 121 through the second connecting member 1243, so that the cylinder output shaft or the oil cylinder output shaft 125 extends outward along the first direction or retracts inward along the first direction.

[0051] The clamping assembly is associated with the driving assembly.

[0052] The clamping and positioning device comprises at least one clamping assembly.

[0053] In some embodiments, the clamping and positioning device may include a clamping assembly.

[0054] In certain embodiments, such as Figures 1 to 3As shown, the pressing and positioning device includes a pair of pressing components, and the two pressing components 13 of this pair of pressing components are respectively arranged on the opposite sides of the pressure actuator 125 in the driving component 12. Among them, the structures of the two pressing components 13 are the same, but this is not a limitation, and the structures of the two pressing components 13 can also be different. In the following description, it is assumed that the structures of the two pressing components 13 are the same. Therefore, one of the pressing components 13 will be taken as an example for description.

[0055] The pressing component 13 includes a movable mounting member 131 and a pressing member 133, and the pressing member 133 is movably arranged on the movable mounting member 131.

[0056] The movable mounting member 131 is arranged on the base 11 along the second direction. The movable mounting member 131 is used to assemble the pressing member 133 and can enable the pressing member 133 to move. In some embodiments, such as Figures 1 to 3 As shown, the movable mounting member 131 can be, for example, a sliding table, the bottom of the sliding table is fixed to the base 11, and the top of the sliding table provides a slideway or a slide rail arranged along the second direction. But this is not a limitation. In other embodiments, the movable mounting member can be, for example, a chute directly opened on the base, and a slideway or a slide rail arranged along the second direction is arranged in the chute.

[0057] The pressing member 133 is movably arranged on the movable mounting member 131 and is associated with the pressure actuator 125 of the driving component 12. In some embodiments, one end of the pressing member 133 is associated with the pressure actuator 125 in the driving component 12, and the other end of the pressing member 133 can be used to press the workpiece. Exemplarily, the pressing member 133 has a connection end connected to the pressure actuator 125 in the driving component 12 and a pressing end for pressing the workpiece, and the connection end and the pressing end are respectively located on the opposite sides of the pressing member 133. Such as Figures 1 to 3 As shown, the pressing member 133 can be, for example, a pressing block or a pressing plate movably arranged on the sliding table as the movable mounting member 131.

[0058] The pressing member 133 is connected to the pressure actuator 125 in the driving component 12. Such as Figures 1 to 3 As shown, a connection head 126 is provided on the pressure actuator 125, and the pressing member is movably connected to the connection head 126 through an adapter assembly 134.

[0059] In some embodiments, the adapter assembly 134 includes an adapter 1341. The first end of the adapter 1341 is rotatably connected to the connection head 126 through a third hinge pin 1342, and the second end of the adapter 1341 is rotatably connected to the pressing member 133 through a fourth hinge pin 1343.

[0060] It should be noted that, as Figures 1 to 3 shown, when there are two pressing components 13, the pressing members 133 in these two pressing components 13 will both be connected to the pressure actuator 125 in the driving component 12. Therefore, when both of the two pressing components 13 are movably connected to the pressure actuator 125 through their respective adapter components 134, two adapter members 1341 belonging to different adapter components 134 can share a third hinge pin 1342. However, this is not limiting. In other embodiments, two adapter members belonging to different adapter components may also each independently use a third hinge pin.

[0061] By using the adapter component 134, the pressing member 133 in the pressing component 13 can be rotatably connected to the pressure actuator 125 in the driving component 12. The movement (extension or contraction) of the pressure actuator 125 in the first direction can drive the rotatably connected pressing member 133 to move (extend or contract) in the second direction.

[0062] In the embodiments of the present disclosure, the first direction and the second direction are different directions and form an angle. In the embodiment as Figures 1 to 3 shown, the first direction is perpendicular to the second direction, that is, the angle between the first direction and the second direction is 90°. Thus, for example, the movement (extension or contraction) of the pressure actuator 125 in the horizontal direction can drive the rotatably connected pressing member 133 to move (extend or contract) in the vertical direction; or, the movement (extension or contraction) of the pressure actuator 125 in the vertical direction can drive the rotatably connected pressing member 133 to move (extend or contract) in the horizontal direction. However, this is not limiting. According to the actual production operation environment and the characteristics of the workpiece, the angle between the first direction and the second direction can still be changed in other ways. For example, the angle between the first direction and the second direction can be, for example, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, or other suitable angles, etc. All of these can make the overall pressing and positioning device more compact to a certain extent, can be applied to the occasions with limited operation space and effectively position and clamp the workpiece, and can avoid damaging the workpiece due to excessive force when the first direction and the second direction coincide (the pressure actuator and the pressing member move in the same direction).

[0063] In the pressing and positioning device provided in the embodiments of the present disclosure, a positioning portion may also be provided on the pressing member, and the workpiece can be positioned by using the positioning portion. As Figures 1 to 3As shown, a plurality of positioning portions 1331 are provided on the pressing member 133, and the positioning portions 1331 are arranged at intervals. Among them, the number of the positioning portions 1331 and the intervals between two adjacent positioning portions can be set according to the actual production operation environment and the characteristics of the workpiece. Exemplarily, the positioning portion 1331 can be, for example, a positioning hole, a positioning recess, or a positioning groove, etc. Taking the positioning portion 1331 as a positioning hole as an example, in practical applications, when clamping the workpiece or performing other operations, move the workpiece and align a specific portion or a specific position of the workpiece (for example, the positioning portion of the workpiece) with the positioning hole serving as the positioning portion 1331 on the pressing member 133 to achieve corresponding positioning. When necessary, other tools can also be used, for example, a dowel pin, etc. to be inserted into the positioning hole serving as the positioning portion 1331 to limit the workpiece to prevent its displacement.

[0064] In addition, in the pressing and positioning device provided in the embodiment of the present disclosure, a limiting portion is provided at the end of the pressure executing member, and a stop structure corresponding to the limiting portion is provided on the base. As Figures 1 to 3 shown, a limiting portion 127 is provided at the end of the pressure executing member 125, and a stop structure 111 corresponding to the limiting portion 127 is provided on the base 11. Exemplarily, the limiting portion 127 can be, for example, a limiting block, and the stop structure 111 can be, for example, a stop seat or a stop block. In some embodiments, a buffer layer is provided on at least one of the limiting block and the stop seat or the stop block, and the buffer layer can be, for example, a rubber layer.

[0065] When applying the pressing and positioning device provided by the present disclosure as Figures 1 to 3When the clamping positioning device is shown, in one case, assuming that in the initial state, the cylinder output shaft or oil cylinder output shaft 125 in the driving assembly 12 is in a retracted position, the clamping block or clamping plate 133 in the clamping assembly 13 is close to the cylinder output shaft or oil cylinder output shaft 125 through the adapter assembly 134; the operator operates the handle 123, and the handle 123 is subjected to force and rotates clockwise with the first connecting member 1221 in the hinge assembly 122 as the fulcrum (that is, the first connecting end of the handle 123) (the handle 123 moves backward away from the cylinder or oil cylinder 121) The second connecting end of the handle 123 pushes the piston of the cylinder or oil cylinder 121 through the second connecting member 1223, so that the cylinder output shaft or oil cylinder output shaft 125 extends outward along the first direction; the outwardly extended cylinder output shaft or oil cylinder output shaft 125 drives the two clamping blocks or clamping plates 133 in the two rotatably connected clamping assemblies 13 to move in opposite directions along the second direction (the clamping member 133 moves outward away from the cylinder output shaft or oil cylinder output shaft 125) through the adapter assembly 134, thereby clamping or clamping the workpiece. Alternatively, in one case, assuming that in the initial state, the cylinder output shaft or oil cylinder output shaft 125 in the driving assembly 12 is in the extended position, and the pressing block or pressing plate 133 in the pressing assembly 13 clamps or presses the workpiece; the operator operates the handle 123, and the handle 123 is subjected to force and rotates counterclockwise (the handle 123 rotates forward close to the cylinder or oil cylinder 121) with the first connecting piece 1221 in the hinge assembly 122 as the fulcrum (that is, the first connecting end of the handle 123), and the second connecting piece 1221 of the handle 123 is rotated counterclockwise. The connecting end pulls the piston of the cylinder or oil cylinder 121 through the second connecting member 1223, so that the cylinder output shaft or oil cylinder output shaft 125 shrinks inward along the first direction; the inwardly shrinking cylinder output shaft or oil cylinder output shaft 125 drives the two clamping blocks or clamping plates 133 in the two rotatably connected clamping assemblies 13 to move toward each other along the second direction through the adapter assembly 134 (the clamping member 133 moves inward close to the cylinder output shaft or oil cylinder output shaft 125), thereby releasing the clamping or clamping of the workpiece.

[0066] The pressing and positioning device provided by the embodiment of the present disclosure includes: a base; a driving assembly disposed on the base; the driving assembly includes a pressure driving source, a force applying member, and a pressure executing member, and the pressure executing member moves along a first direction under the drive of the pressure driving source; a pressing assembly, including a movable mounting member and a pressing member, the movable mounting member is disposed on the base along a second direction, and the pressing member is movably disposed on the movable mounting member and is associated with the pressure executing member of the driving assembly. The pressing and positioning device provided by the embodiment of the present disclosure adopts a non-direct pushing design. The pressure executing member in the driving assembly moves along the first direction under the drive of the pressure driving source and causes the associated pressing member to move relative to the movable mounting member along the second direction to clamp or press the workpiece. Compared with the related art, the pressing and positioning device provided by the embodiment of the present disclosure has the advantages of compact structure and convenient operation, can be applied to the occasions with limited operation space, effectively position and clamp the workpiece, and can avoid damaging the workpiece due to excessive force.
