Description

Technical Field

[0001] The invention relates to the technical field of positioning and clamping, in particular to a novel positioning and clamping device. Background Art

[0002] At present, the positioning and clamping needs for large equipment in industrial production require high-strength clamping force and high-precision repeated positioning functions.

[0003] However, the existing common equipment clamping form has the problem of low clamping force, which cannot meet the needs of users in positioning and clamping large external equipment (such as Figure 1 When the vehicle body side panel assembly 1000 is shown, high-strength clamping requirements are put forward.

[0004] It should be noted that the body side panel assembly 1000 needs to be welded to the external main body using an existing welding robot. The clamping and positioning of the body side panel assembly 1000 during welding directly affects the overall matching accuracy between the body side panel assembly and the main body. At the same time, due to the large weight of the body side panel assembly 1000 (generally weighing 4 to 5 tons), higher requirements are placed on the size of the clamping force, that is, high-strength clamping force (i.e. clamping force) is required. Summary of the invention

[0005] The purpose of the present invention is to provide a novel positioning clamping device in view of the technical defects existing in the prior art.

[0006] To this end, the present invention provides a novel positioning and clamping device, including a device for positioning and clamping a vehicle body side panel assembly;

[0007] The upper and lower ends of the left and right sides of the body side assembly are respectively provided with a support column protruding horizontally outward;

[0008] A vertically distributed clamping block is fixedly arranged on the front side of each supporting column;

[0009] The front side surface of each clamping block is an inclined surface, and the longitudinal width of each clamping block gradually increases from bottom to top;

[0010] The novel positioning and clamping device comprises two vertically distributed supporting columns;

[0011] The two supporting columns are symmetrically distributed on the left and right;

[0012] Two support columns are provided with a blocking block at the upper and lower ends of the opposite sides respectively;

[0013] Directly below each blocking block, a clamping and positioning module is provided;

[0014] The clamping and positioning module is used to position and clamp the four clamping blocks on the body side assembly when the four supporting columns of the body side assembly are respectively placed on the top rear sides of the four clamping and positioning modules and fit with the blocking blocks on the supporting columns.

[0015] It can be seen from the technical solution provided by the present invention that, compared with the prior art, the present invention provides a new positioning and clamping device, which is scientifically designed and can meet the high strength requirements put forward by users when positioning and clamping large vehicle body side panel assemblies. It can reliably position and clamp the vehicle body side panel assemblies, and has great practical significance.

[0016] Compared with the previous direct and simple cylinder clamping form, the present invention can better meet the high-strength positioning and clamping requirements of the vehicle body side assembly, is more in line with the development trend and demand of the current market, and has a very significant application effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] See also Figures 1 to 6 , the present invention provides a novel positioning and clamping device for positioning and clamping a vehicle body side panel assembly 1000;

[0034] The left and right sides of the vehicle body side assembly 1000 are provided with a support column 1001 protruding horizontally outward at the upper and lower ends respectively;

[0035] A vertically distributed clamping block 5 is fixedly disposed on the front side of each support column 1001;

[0036] The front side surface of each clamping block 5 is an inclined surface, and the longitudinal width (i.e., thickness) of each clamping block 5 gradually increases from bottom to top;

[0037] The novel positioning and clamping device comprises two vertically distributed supporting columns 200;

[0038] The two supporting columns 200 are symmetrically distributed on the left and right sides;

[0039] The two support columns 200 are respectively provided with a blocking block 400 at the upper and lower ends of the opposite sides; that is, there are four blocking blocks 400 in total;

[0040] A clamping and positioning module 300 is disposed directly below each blocking block 400; that is, there are four clamping and positioning modules 300 in total;

[0041] The clamping and positioning module 300 is used to perform positioning and clamping operations on the four clamping blocks 5 on the body side assembly 1000 when the four support columns 1001 of the body side assembly 1000 are respectively placed on the top rear sides of the four clamping and positioning modules 300 and are in contact with the blocking blocks 400 on the support columns 200.

[0042] In the present invention, in specific implementation, each clamping and positioning module 300 includes a hollow positioning box main box body 100;

[0043] Each positioning box main body 100 is pivotally connected (i.e. rotatably connected) to a first roller 171 at both the front and rear sides and the upper and lower ends;

[0044] A cylinder support 8 is fixedly disposed at the bottom of each positioning box main body 100;

[0045] A cylinder 15 is provided at the bottom of each cylinder support 8;

[0046] The power output end (i.e., piston rod) at the top of each cylinder 15 passes through the support through hole 801 reserved on the cylinder support 8 and is respectively connected to the lower end of a cylinder joint 7;

[0047] The upper end of each cylinder joint 7 vertically passes through the through hole reserved at the bottom of the positioning box main body 100, and is respectively connected to the lower end of a vertically distributed guide column 1;

[0048] The front and rear side walls of each guide column 1 are in contact with the adjacent first roller wheels 171 respectively;

[0049] Each positioning box main body 100 has a guide column lifting inlet and outlet hole at the top corresponding to the guide column 1;

[0050] The upper end of each guide column 1 is respectively pivotally connected (i.e. rotatably connected) with a second roller wheel 172;

[0051] The cylinder 15 in the four clamping and positioning modules 300 is used to drive the connected guide column 1 to move upward in the vertical direction when the four support columns 1001 of the body side panel assembly 1000 are respectively placed on the top rear side of the four positioning box main boxes 100 and are in contact with the blocking blocks 400 on the supporting columns 200, so that the second roller wheel 172 at the upper end of the guide column 1 slides upward along the inclined surface of the clamping block 5 on the adjacent support column 1001, thereby clamping the four support columns 1001 of the body side panel assembly 1000, thereby completing the positioning and clamping operation of the body side panel assembly 1000.

[0052] In the present invention, in a specific implementation, the blocking block 400 is in an L-shape.

[0053] It should be noted that the four clamping and positioning modules 300 on the two supporting columns 200 are symmetrically distributed.

[0054] In the present invention, in a specific implementation, the upper end of the guide column 1 is pivotally connected to the second roller wheel 172 through the first shaft pin 9;

[0055] It should be noted that the clamping block 5 is installed on the body side panel assembly 1000. When the body side panel assembly 1000 needs to be clamped, the body side panel assembly 1000 is in contact with the blocking block 400 on the supporting column 200 and is located on the top rear side of the positioning box main box 100. At this time, the inclined surface of the clamping block 5 is facing the second roller wheel 172. When the second roller wheel 172 slides upward along the front inclined surface of the clamping block 5 under the action of the cylinder 15, an inward clamping force is generated, thereby achieving the clamping function.

[0056] With respect to the present invention, when the clamping block 5 on the body side panel assembly 1000 is clamped and positioned, the second roller wheel 172 slides up along the inclined surface of the clamping block 5, thereby generating two components of force, one upward and the other inward (i.e., toward the direction of the body side panel assembly 1000, i.e., the rear direction). After the upward component of force is offset by the self-weight of the body side panel assembly 1000, the remaining inward clamping force is used, thereby realizing the function of clamping the body side panel assembly 1000.

[0057] In the present invention, in a specific implementation, a shaft pin limit block 1a is vertically arranged at the left and right ends of the top of the guide column 1;

[0058] Each shaft pin limiting block 1a is provided with a first shaft pin mounting hole 1b which is distributed laterally;

[0059] The two first shaft pin mounting holes 1b are respectively connected to two ends of a first shaft pin 9.

[0060] In specific implementation, each shaft pin limit block 1a is fastened to one end of the first shaft pin 9 through a fastening screw 18; the specific structure is as follows:

[0061] Each shaft pin limit block 1a is provided with a vertically distributed top screw installation hole 1c on its upper portion, and the lower portion of the top screw installation hole 1c is connected to the upper side of the first shaft pin installation hole 1b;

[0062] After each fastening screw 18 vertically passes through a screw installation hole 1c on an axle pin limiting block 1a, the bottom of each fastening screw 18 is in tight contact with the top of one end of the first axle pin 9.

[0063] In the present invention, in a specific implementation, the lower end of the guide column 1 is provided with a cylinder joint mounting groove;

[0064] The upper end of the cylinder joint 7 is embedded in the cylinder joint mounting groove.

[0065] In the present invention, in a specific implementation, the main box body 100 of the positioning box includes a positioning box cover plate 4 and a positioning box back plate 3 which are distributed at intervals;

[0066] The inner ring of each first roller wheel 171 is respectively provided with a first shaft pin 10 which is transversely penetrated;

[0067] Both ends of each first shaft pin 10 are respectively embedded in a shaft pin installation hole reserved on the positioning box cover plate 4 and a shaft pin installation hole reserved on the positioning box back plate 3;

[0068] In specific implementation, the inner end of each first axle pin 10 protrudes from the pin installation hole reserved on the positioning box cover plate 4;

[0069] The positioning box cover plate 4 is provided with a pin stop plate 11 just above each pin installation hole thereon;

[0070] Each pin stopper plate 11 has a bottom with an arc-shaped limit groove opening downward;

[0071] The top of the inner end of the first shaft pin 10 is in tight contact with the arc-shaped limiting groove of a shaft stop plate 11 respectively.

[0072] In specific implementation, the front and rear ends of the positioning box cover plate 4 and the positioning box back plate 3 are fixedly connected by a positioning box side plate 2 respectively;

[0073] A roller through hole 201 is provided at the upper and lower ends of the two positioning box side plates 2;

[0074] The roller through hole 201 is used to receive the first roller 171 during installation.

[0075] It should be noted that, for the present invention, the first roller 171 has two functions: one is to provide guidance when the cylinder 15 pushes the guide column 1 to rise; the other is to clamp and position the body side assembly 1000, because the body side assembly 1000 and the blocking block 400 on the supporting column 200 are in a fitted state, the cylinder 15 outputs a thrust to push the roller 172, so that the second roller 172 slides up along the front inclined surface of the clamping block 5, and the first roller 171 uses itself as a fulcrum to generate an inward (i.e., toward the body side assembly 1000, i.e., the rear direction) reverse force, thereby achieving the effect of increasing the clamping force.

[0076] For the present invention, the main functions of the guide column 1 are: first, to provide a guiding function for the lifting and lowering of the second roller wheel 172; second, when in a clamping state, an inward reverse force is applied to the guide column 1 through the first roller wheel 171, thereby enhancing the clamping force on the vehicle body side assembly 1000.

[0077] It should be noted that the shape and size of the roller through hole 201 are larger than the shape and size of the first roller wheel 171 .

[0078] In the present invention, in a specific implementation, a vertically distributed switch mounting plate mounting opening 202 is provided on the positioning box side plate 2 located at the front side;

[0079] A switch mounting plate 7 is provided coveringly on the switch mounting plate mounting opening 202;

[0080] The switch mounting plate 7 is vertically penetrated by two induction switches 14 (i.e., proximity switches) distributed vertically.

[0081] It should be noted that the switch mounting plate 7 has a through hole for mounting the induction switch.

[0082] The sensing end at the rear side of each sensing switch 14 longitudinally penetrates the sensing switch mounting through hole and the switch mounting plate mounting opening reserved on the positioning box side plate 2 and extends into the inner cavity of the positioning box main body 100 .

[0083] In a specific implementation, the induction switch is an existing proximity switch, for example, a proximity switch of the brand TURCK (including but not limited to this brand model) with a model number of BI5-M18-AP6X-H1141 can be used.

[0084] In specific implementation, a longitudinally distributed hexagonal bolt 12 is provided on the upper part of the front side of each guide column 1 (the front side of the guide column 1 has a bolt mounting hole);

[0085] The hexagonal bolt 12 is arranged correspondingly to the induction switch 14 (ie, arranged correspondingly in front and behind). The hexagonal bolt 12 will pass behind the two induction switches 14 along the movement trajectory when the guide column 1 rises.

[0086] It should be noted that the function of the external hexagonal bolt 12 is as follows: when the cylinder 15 pushes the guide post 1 to rise, the external hexagonal bolt 12 located on the side of the guide post 1 triggers the sensing signal of the sensing switch 14 .

[0087] In a specific implementation, the external hexagonal bolt 12 is also threadedly fixedly connected to a hexagonal nut 13 at the connection with the front side of the guide column 1 .

[0088] It should be noted that the hexagonal nut 13 is used to lock the position of the external hexagonal bolt 12 to prevent the external hexagonal bolt 12 from loosening and avoid causing the induction switch 14 to have no induction signal.

[0089] In a specific implementation, the induction switch 14 is used to feed back the stroke state of the cylinder 15 by sensing the external hexagonal bolt 12 to confirm the clamping state.

[0090] In the present invention, in a specific implementation, a vertically distributed lining plate 16 is respectively provided on the opposite side of the positioning box cover plate 4 and the positioning box back plate 3;

[0091] It should be noted that the two lining plates 16 are located on the left and right sides of the guide column 1 and are not connected to the guide column 1 .

[0092] It should be noted that the function of the liner 16 is to reduce friction when the guide column 1 moves up and down. The surface of the liner 16 facing the guide column has graphite particles that reduce friction, and its essential function is to reduce friction and slow down friction wear in a mechanism with relative motion.

[0093] In order to more clearly understand the technical solution of the present invention, the assembly process of a clamping and positioning module 300 in the present invention is described below.

[0094] First, a lining plate 16 is installed on the positioning box back plate 3 and the positioning box cover plate 4 respectively;

[0095] Then, two positioning box side panels 2 are installed on the positioning box back panel 3, and the positioning box cover panel 4 is connected to the positioning box side panels 2 on both sides thereof, thereby preliminarily constructing the positioning box main box body 100;

[0096] Then, the four roller wheels 17 are respectively inserted into the four roller through holes 201 (i.e., side holes) on the side plate 2 of the positioning box, and are positioned with the second pin shaft 10 and fastened with the pin shaft stopper plate 11, thereby completing the construction of the main box body 100 of the positioning box;

[0097] Next, the cylinder 15 is mounted on the cylinder support 8, and the cylinder joint 7 is installed to complete the construction of the power component;

[0098] Next, the second roller wheel 172 is embedded in the upper end of the guide column 1, and is positioned and connected with the first pin 9, and then fastened with the fastening screw 18, and then the guide column 1 is inserted into the inner cavity of the main box body 100 of the positioning box from top to bottom;

[0099] Next, install the external hexagonal bolt 12 and the hexagonal nut 13 on the side of the guide column 1 through the switch mounting plate installation opening on the side plate 2 of the positioning box, and insert the cylinder joint 7 in the power component into the cylinder joint installation groove at the lower end of the guide column 1 to achieve fixed connection;

[0100] Then, two induction switches 14 are installed on a switch mounting plate 6, and then, the switch mounting plate 6 is covered and mounted on the switch mounting plate mounting opening on the positioning box side plate 2, so that the sensing end on the rear side of the induction switch 14 extends into the inner cavity of the positioning box main box body 100, thereby completing the installation of the clamping positioning module 300.

[0101] After the assembly operation of the four clamping and positioning modules 300 is completed, the four clamping and positioning modules 300 and the four blocking blocks 400 are installed on the two vertically distributed supporting columns 200. Then, by placing the four supporting columns 1001 of the body side assembly 1000 on the top rear side of the four positioning box main boxes 100 respectively, and installing the four clamping blocks 5 on the front side of the four supporting columns 1001, the cylinder action of the clamping and positioning module 300 can be controlled to form a positioning clamping state for the body side assembly 1000.

[0102] In order to more clearly understand the technical solution of the present invention, the working principle of the present invention is explained below.

[0103] The new positioning clamping device of the present invention is a high-precision, new positioning clamping device. It abandons the previous form of single cylinder support and uses the cylinder push and roller as a guide to ensure the repeatability stability of the mechanism, thereby achieving high repeatability positioning accuracy of the equipment. At the same time, it also uses the output of the cylinder itself and the reverse force of the roller to form a combined force on the clamping surface of the clamping block (that is, the inclined surface on the front side of the clamping block), thereby achieving a high-intensity clamping force equivalent to six times the output of the cylinder.

[0104] In a specific implementation, the clamping block 5 is made of quenched 45 steel.

[0105] It should be noted that, for the present invention, when the body side assembly 1000 is clamped and positioned, the cylinder 15 pushes the guide column 1 to rise, thereby driving the second roller 172 located at the upper end of the guide column 1 to slide upward along the front inclined surface of the clamping block 5, thereby generating two components of force, an upward component and an inward (i.e., backward) component. After the upward component of force is offset by the weight of the body side assembly 1000 itself, the remaining inward clamping force achieves the clamping function; when clamping and positioning, since the body side assembly 1000 and the supporting column (external equipment) are in a fitted state, the cylinder 15 outputs a thrust to push the second roller 172 to slide down along the inclined surface of the clamping block 5, and the guide column 1 generates an extrusion force on the first roller 171 (only the two first rollers 171 on the front side), and the first roller 171 (only the two first rollers 171 on the front side) generates an inward reverse force with itself as the fulcrum, thereby achieving the effect of increasing the clamping force.

[0106] For the present invention, in a specific implementation, when it is necessary to clamp and position the body side assembly 1000, first, move the body side assembly 1000 so that it fits with the blocking block 400 of the support column 200. At this time, the cylinder 15 on the four clamping and positioning modules 300 installed on the support column 200 extends to push the guide column 1 up, thereby driving the second roller 172 located at the upper end of the guide column 1 to slide down along the inclined surface of the clamping block 5 pre-installed on the body side assembly 100. Two components of force, upward and inward, are generated during the sliding process, and the upward component of force is offset by the weight of the body side assembly 100 itself. After that, there is a remaining inward clamping force, thereby achieving the clamping function; during this period, the first roller 171 and the guide column 1 always maintain a close contact state, and when the cylinder 15 extends to push the guide column 1 to rise, the second roller 172 located at the upper end of the guide column 1 slides up along the front inclined surface of the clamping block 5, causing the guide column 1 to generate an extrusion pressure on the first roller 171 (only the two first rollers 171 on the front side). At this time, the first roller 171 uses itself as a fulcrum to generate an inward reverse force, thereby achieving the effect of increasing the holding force, thereby completing the positioning and clamping function of the body side assembly 1000.

[0107] To sum up, compared with the prior art, the new positioning and clamping device provided by the present invention is scientifically designed and can meet the high strength requirements put forward by users when positioning and clamping large vehicle body side panel assemblies. It can reliably position and clamp the vehicle body side panel assemblies, and has great practical significance.

[0108] Compared with the previous direct and simple cylinder clamping form, the present invention can better meet the high-strength positioning and clamping requirements of the vehicle body side assembly, is more in line with the development trend and demand of the current market, and has a very significant application effect.

[0109] After inspection, the new positioning and clamping device provided by the present invention is a new device for positioning and clamping the body side assembly, which is high-strength, easy to install, safe and reliable, easy to replace, and occupies a small space. The present invention can output a high-strength clamping force equivalent to 6 times the output of the cylinder, has a stable and reliable structure, is widely applicable, and has a significant application effect.

[0110] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
