[0030] See also Figures 1 to 5 , the utility model provides a workpiece position adjustment device, comprising: a main body bottom plate 1;

[0031] A conveying mechanism 3 and a transmission mechanism 2 are provided on the top of the main body bottom plate 1;

[0032] The conveying mechanism 3 includes a conveying slide 302 and a conveying guide rail 303;

[0033] A longitudinally distributed conveying guide rail 303 is provided at the top left end of the main body bottom plate 1;

[0034] The top of the conveying guide rail 303 (specifically, the top of the slider on the conveying guide rail 303) is provided with two transversely distributed conveying slides 302 which can slide longitudinally;

[0035] The transmission mechanism 2 comprises a transmission cylinder 201 and a transmission rod 202;

[0036] The transmission cylinder 201 is arranged at the top right end of the main body bottom plate 1;

[0037] The output end (i.e., the cylinder joint) on the left side of the transmission cylinder 201 is hinged (i.e., rotatably connected) to the right ends of the two transmission rods 202;

[0038] The left ends of the two transmission rods 202 are hinged to the right ends of the two conveying slides 302;

[0039] The top of each conveying slide 302 is used to place a workpiece (such as a car body or other workpiece) whose position is to be adjusted.

[0040] It should be noted that, through the telescopic movement of the output end of the transmission cylinder 201, the two conveying slides 302 are correspondingly driven to move away from each other or relative to each other, that is, to move away from each other or closer to each other.

[0041] It should be noted that the slider on the conveying guide rail 30 can slide back and forth on the guide rail body under the drive of external force; the structure of the conveying guide rail 30 is a mature and conventional linear guide structure in the prior art, which is a well-known technology and will not be described in detail here.

[0042] In the present invention, in specific implementation, the output end on the left side of the cylinder 201 is hinged to the right ends of the two transmission rods 202 through a transmission pin 203;

[0043] The left ends of the two transmission rods 202 are hinged to the right ends of the two conveying slides 302 through a transmission pin 203 respectively.

[0044] In a specific implementation, the lower end of the transmission pin shaft 203 is fixedly connected to a latch pin or a nut.

[0045] In the present invention, in a specific implementation, a top end of each conveying slide 302 is provided with a plurality of positioning pins 304 distributed at intervals.

[0046] In specific implementation, four positioning pins 304 are provided at one end of the top of each conveying slide 302;

[0047] The center points of the four positioning pins 304 are connected to form a square.

[0048] In the present invention, in specific implementation, a conveying slide limit block 301 is vertically provided at the right end of each conveying slide 302 .

[0049] In specific implementation, a limit block mounting hole 3020 is provided at the right end of each conveying slide 302;

[0050] A conveying slide limit block 301 is disposed through the limit block installation hole 302 .

[0051] In the present utility model, the specific implementation is as follows: Figure 4, the workpiece position adjustment device of the utility model further includes two positioning pin connectors 305;

[0052] The two positioning pin connectors 305 are connected to the left side walls of the two conveying slides 302 through an L-shaped adapter block 306 respectively;

[0053] The two positioning pin connectors 305 are symmetrically distributed front and back;

[0054] It should be noted that the two positioning pin connectors 305 are used to accurately position the body parts that need to be transported, so that the body parts remain stable and do not shift during the movement, thereby improving the welding accuracy of the car itself.

[0055] In the present utility model, in specific implementation, it also includes a limiting mechanism 4;

[0056] The limiting mechanism 4 comprises two limiting blocks 401 and two limiting block connecting members 402;

[0057] Two limit stopper connectors 402 are respectively located at the front and rear sides of the top left end of the main body bottom plate 1;

[0058] A limit stopper 401 is provided on each of the two opposite sides of the limit stopper connectors 402;

[0059] The two limit blocks 401 are respectively arranged corresponding to the conveying slide limit blocks 301 in the two conveying slides 302 .

[0060] In a specific implementation, the bottom surface height of the conveying slide limit block 301 of the two conveying slides 302 is greater than the bottom surface height of the limit block 401 , and less than the top surface height of the limit block 401 .

[0061] The two conveying slide limit blocks 301 are respectively located right behind one limit block 401 and right in front of the other limit block 401 .

[0062] It should be noted that the conveyor slide limit block 301 is arranged on the conveyor slide 302. When the conveyor slide 302 moves longitudinally along the conveying guide rail 303, the positioning pin and the fixed workpiece thereon also move longitudinally together. At this time, if the conveyor slide limit block 301 is in tight contact with the limit stop block 401, the conveyor slide 302 will be restricted from continuing to move due to the existence of the limit stop block 401. At this time, the transmission cylinder 201 will always maintain the thrust output, so that the conveyor slide limit block 301 can continue to stably contact with the limit stop block 401, thereby achieving the effect of stabilizing the conveyor slide 302 and the workpiece thereon.

[0063] In specific implementation, each limit stopper connector 402 includes a horizontal connecting section 4021 and a vertical connecting section 4022;

[0064] The horizontal connecting section 4021 is fixedly connected to the top of the main body bottom plate 1;

[0065] A vertical connecting section 4022 is vertically disposed at the top outer side ends (i.e., the ends facing away) of the two horizontal connecting sections 4021;

[0066] A limit stopper 401 is fixedly disposed on each opposite side of the two vertical connecting sections 4022 .

[0067] In a specific implementation, the overall shape of the limit stopper connector 402 is "L"-shaped.

[0068] Furthermore, an adjustment gasket can be set between the limit block connector 402 and the top of the main body bottom plate 1. By adjusting the gasket, the vertical height of the limit block connector 402 can be adjusted so that the limit block connector 402 and the conveying slide limit block 301 in the conveying slide 302 are in a corresponding position to ensure the accuracy of the limit.

[0069] In the present invention, it should be noted that the size and number of the main body bottom plate 1 are determined according to the size and number of the workpieces (such as body-in-white parts) that are actually positioned and moved.

[0070] The two conveyor slides 302 are equipped with four positioning pins 304. The positions of the conveyor slides 302, the positioning pins 304 and the workpieces positioned thereon (such as white body parts) are determined and adjusted by the extension and retraction of the transmission cylinder 201. When the transmission cylinder 201 is extended, the two conveyor slides 302 are opened upward and downward respectively. After being in place, the sensor provided by the transmission cylinder 201 can feedback the cylinder head position.

[0071] In the present utility model, in a specific implementation, the transmission cylinder 201 is arranged at the top right end of the main body bottom plate 1 through the cylinder mounting connection frame 204.

[0072] In a specific implementation, the overall shape of the cylinder mounting bracket 204 is "L"-shaped.

[0073] It should be noted that, for the present invention, the left end of the transmission cylinder 201 is connected with a cylinder joint, and the two transmission rods 202 are hingedly connected by a rotating pin (i.e., the transmission pin 203), and the left end of the transmission rod 202 is also equipped with a rotating pin (i.e., the transmission pin 203) and hingedly connected with the conveying slide 302 to ensure the transmission of power. In this way, when the transmission cylinder 201 performs telescopic movement, the two conveying slides 302 can move up and down along the conveying guide rail 303.

[0074] It should be noted that when the present invention is working, the conveying slide 302 fixes the workpiece to be adjusted (e.g., a body-in-white panel, the body-in-white is the body of the vehicle, and the workpiece has a positioning hole corresponding to the positioning pin) through the positioning pin 304, and then the transmission cylinder 201 is pushed to the left, driving one end of the transmission rod 202 to move, thereby driving the conveying slide 302 hinged to the other end of the transmission rod 202 to move, and further making the two conveying slides 302 move up and down along the conveying guide rail 303 (i.e., move in opposite directions);

[0075] In addition, the sensor on the transmission cylinder 201 can detect the extension position of the cylinder. When the preset position is reached, the sensor can send a trigger signal to an external console (such as an industrial computer), and the console then triggers and controls the welding robot to perform welding operations. When the welding is completed, the welding robot sends a completion signal to the console, and the console then sends a control signal to control the transmission cylinder 201 to continue to work, extend or retract.

[0076] Compared with the prior art, the workpiece position adjustment device provided by the utility model has the following beneficial effects:

[0077] 1. The conveying slide 302 of the utility model and the workpiece to be processed set thereon can realize accurate position adjustment and positioning through the movement of the transmission cylinder at the other end to meet the position movement requirements of workpieces of various sizes (such as white body panels of different sizes).

[0078] 2. The limiting mechanism of the utility model is easy to install and can effectively limit the conveying slide 302.

[0079] 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 protection scope of the present invention.
