Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically a beam clamp with a lifting mechanism. Background Technology

[0002] Crossbeams not only ensure the torsional rigidity of the frame and bear longitudinal loads, but also support the main components of the vehicle. Typically, trucks have 5 to 6 crossbeams, and sometimes more. The structural feature of the side beam frame is that it is convenient to install the cab, cargo box, and some special equipment and arrange other assemblies. It is beneficial for modifying and developing modified vehicles and developing a variety of vehicles. Therefore, it is widely used in trucks and most special vehicles.

[0003] For example, patent CN216326149U discloses a novel welding fixture for automotive crossbeam assembly, including a platform assembly. The bottom of the platform assembly is provided with a fixed frame, and a partition is provided between the left and right sides of the inner wall of the fixed frame. An adjustment component is provided on the inner top wall of the fixed frame, one end of which is slidably connected to the top of the partition. The top of the adjustment component extends to the top of the platform assembly, and the right side of the adjustment component extends to the right side of the fixed frame.

[0004] The aforementioned patented device, by setting up a servo motor, drives the second bevel gear to rotate through the output shaft. The rotation of the second bevel gear drives the first bevel gear and the rotating shaft to rotate, causing the gear to move the rack plate. The movement of the rack plate, in turn, moves the right-side clamping assembly through the adjusting rod, thereby achieving the clamping of automobile crossbeams of different lengths, improving the practicality of the device and making it easier for people to use. However, the disadvantages of the aforementioned patent are: the positioning effect is generally poor, and the aforementioned patent can only fix a single component of the crossbeam.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Please see Figure 1-7 A beam clamp with a lifting mechanism includes an end component fixing clamp 100 and a middle component fixing clamp 200; the end component fixing clamp 100 is provided with two sets located on the left and right sides of the middle component fixing clamp 200 respectively; both sets of end component fixing clamps 100 and middle component fixing clamps 200 are fixedly installed on the top of the base plate 300.

[0027] The end component fixing clamp 100 includes a first base 101, a first main board 102 is fixedly connected to the top of the first base 101 by bolts, and the rear top of the first main board 102 is rotatably connected to the lower end of the first upper clamping seat 103 by a pin; a first clamping cylinder 104 is also rotatably connected to the rear side of the first main board 102, and the output shaft end of the first clamping cylinder 104 is also rotatably connected to the rear end of the first upper clamping seat 103 by a pin. The action of the first clamping cylinder 104 can drive the front end of the first upper clamping seat 103 to open and close, thereby achieving the clamping of the crossbeam;

[0028] The front end of the first upper clamping seat 103 is provided with a first upper clamping arm 105, and a plurality of first upper clamping pressure blocks 106 are fixedly installed at the bottom of the first upper clamping arm 105 by bolts.

[0029] The first motherboard 102 is also fixedly installed on the left and right sides of the front top. The top of the first lower clamping arm 107 is fixedly installed with several first lower clamping pads 108 by bolts, and the first upper clamping pressure block 106 is set in a one-to-one correspondence with the first lower clamping pads 108.

[0030] When the crossbeam is clamped, the components of the crossbeam to be processed are placed on the first lower clamping pad 108. The action of the first clamping cylinder 104 drives the front end of the first upper clamping seat 103 to close, and the first upper clamping pressure block 106 presses on the top of the crossbeam.

[0031] Meanwhile, since the first upper clamping block 106 and the first lower clamping pad 108 are both fixed by bolts in this solution, the first upper clamping block 106 and the first lower clamping pad 108 of different sizes can be replaced according to different shapes of crossbeams to meet the clamping requirements of crossbeams of different specifications.

[0032] Meanwhile, in this solution, the first motherboard 102 is also fixedly mounted on both sides by bolts with first fixed positioning pin mounting seats 109, and the first fixed positioning pins 110 are fixedly mounted on the first fixed positioning pin mounting seats 109 by bolts.

[0033] During installation, the first fixing and positioning pin 110 is inserted into the existing hole on the crossbeam assembly to be welded, thereby positioning the crossbeam.

[0034] The mid-section component fixing fixture 200 includes a second base 201, a second main plate 202 is fixedly connected to the top of the second base 201 by bolts, and the rear top of the second main plate 202 is rotatably connected to the lower end of the second upper clamping seat 203 by a pin; a second clamping cylinder 204 is also rotatably connected to the rear side of the second main plate 202, and the end of the output shaft of the second clamping cylinder 204 is also rotatably connected to the rear end of the second upper clamping seat 203 by a pin. The action of the second clamping cylinder 204 can drive the front end of the second upper clamping seat 203 to open and close, thereby achieving the clamping of the crossbeam;

[0035] The front end of the second upper clamping seat 203 is provided with a second upper clamping arm 205, and a number of second upper clamping pressure blocks 206 are fixedly installed at the bottom of the second upper clamping arm 205 by bolts.

[0036] A second lower clamping arm 207 is also fixedly installed on one side of the front top of the second motherboard 202. Several second lower clamping pads 208a are fixedly installed on the top of the second lower clamping arm 207 by bolts.

[0037] On the other side of the second motherboard 202, there is also a third base 209. The top of the third base 209 is fixedly connected to a third lower clamping arm 211 by bolts. The top of the third lower clamping arm 211 is fixedly installed with several second lower clamping pads b210 by bolts.

[0038] Furthermore, the second upper clamping pressure block 206 is set in a one-to-one correspondence with the second lower clamping pad block a208 and the second lower clamping pad block b210;

[0039] When the crossbeam is clamped, the components of the crossbeam to be processed are placed on the second lower clamping pad a208 and the second lower clamping pad b210. The action of the second clamping cylinder 204 drives the front end of the second upper clamping seat 203 to close, and the second upper clamping pressure block 206 presses on the top of the crossbeam.

[0040] A second movable positioning pin mounting seat 220 is also provided on one side of the third base 209. A second cylinder 221 is fixedly mounted on the front end of the second movable positioning pin mounting seat 220. A second positioning pin mounting arm 222 is fixedly mounted on the output shaft of the second cylinder 221. A second movable positioning pin 223 is fixedly mounted on the top of the second positioning pin mounting arm 222.

[0041] It is worth noting that in this solution, the second movable positioning pin 223 is inclined. In use, the component of the crossbeam to be processed is first placed on the second lower clamping pad a208 and the second lower clamping pad b210. Then, the second cylinder 221 drives the second movable positioning pin 223 to tilt upward and insert it into the original hole on the crossbeam component to be welded, thereby achieving the positioning of the crossbeam. Then, the action of the second clamping cylinder 204 drives the front end of the second upper clamping seat 203 to close, and the second upper clamping pressure block 206 presses on the top of the crossbeam to achieve the fixation of the crossbeam component.

[0042] In this solution, the front end of the end component fixing clamp 100 is also provided with an auxiliary lifting device 400, the auxiliary lifting device 400 includes a first lifting cylinder 401; the first lifting cylinder 401 is vertically fixedly installed at the front end of the first lifting mounting base 402, a first lifting plate 403 is fixedly installed on the output shaft of the first lifting cylinder 401, and a lifting rod 404 is fixedly installed on the top of the first lifting plate 403;

[0043] When using this utility model, one component of the crossbeam is placed on the end component fixing clamp 100 and the middle component fixing clamp 200 on the right side of the base plate 300, and then the other component is placed on the end component fixing clamp 100 on the left side of the base plate 300, thus fixing the two components.

[0044] After the welding work is completed, the action of the first clamping cylinder 104 causes the first upper clamping seat 103 to open, and at the same time the action of the lifting cylinder 601 causes the lifting plate 603 to rise. At this time, the lifting rod 604 lifts the crossbeam, thereby preventing the crossbeam from sticking to the lower clamping seat 107 due to gravity or welding heat, making it difficult for the worker to remove the crossbeam smoothly.
