Like reference numerals in the figures denote like or similar structures, and thus their repetitive description will be omitted.
[0035] In the present utility model, the words describing positions and directions are illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all changes made are included in the protection scope of the present utility model.
[0036] Referring to Figures 1 to 4 , this application provides a low-temperature screen-burning fixture locking tooling, which includes a main frame 101. A guard plate 1011 can be arranged on the outer periphery of the main frame 101, so as to form a relatively enclosed space inside the main frame 101.

A slideway assembly is arranged on the main frame 101 for conveying the fixture. The slideway assembly is sequentially divided into a workpiece loading position 601, a workpiece pressing position 602, and a workpiece unloading position 603 from one side to the other side. A sub-frame 201 is arranged at the workpiece pressing position 602 of the main frame 101, and a pressing device is arranged on the sub-frame 201 for pressing the fixture at the workpiece pressing position 602 for fastening. A control device is arranged on the main frame 101 for controlling the operation of the pressing device and displaying the magnitude of the pressing force when the pressing device presses the fixture.
[0037] It should be noted that the fixture is loaded from the workpiece loading position 601 and unloaded from the workpiece unloading position 603. Specifically, the fixture to be locked is placed on the slideway assembly from one side of the workpiece loading position 601, and the locked fixture can be removed from this locking tooling from one side of the workpiece unloading position 603. It can be understood that the positions of the workpiece loading position 601 and the workpiece unloading position 603 can be relatively changed, that is, the fixture to be locked can also be placed on the slideway assembly from one side of the workpiece unloading position 603, and the locked fixture can also be taken out from one side of the workpiece loading position 601.
[0038] In a specific embodiment, the jig includes a top plate kit 301, a bottom plate kit 302, a workpiece body 303 located between the top plate kit 301 and the bottom plate kit 302, and a plurality of bolt assemblies 304 for connecting the top plate kit 301 and the bottom plate kit 302; when the pressing device presses the jig to reach a preset pressing force, the pressing device maintains the preset pressing force unchanged and fastens the bolt assemblies 304 respectively with a predetermined torque.
[0039] Thus, the locking tooling presses the low-temperature screen burning jig through the pressing device, and realizes visual adjustment of the pressing force of the pressing device through the control device. After the jig is pressed, the bolt assemblies 304 of the jig are tightened centrally to reach a predetermined torque, and then the pressing device resets and automatically releases the jig, thus completely solving the non-uniformity of manually tightening the bolt assemblies 304 one by one, reducing the labor intensity and difficulty of employees, improving the locking efficiency of the jig, reducing the operation cost. Compared with the original manual locking method, it effectively improves the uniformity and accuracy of the workpiece locking torque requirements, improves the production capacity of the enterprise, effectively reduces the work intensity and difficulty of personnel, and provides conditions for the enterprise to realize production automation and assembly line operation.
[0040] In a specific embodiment, the slideway assembly includes a slideway bracket 401 arranged on the main frame 101, and a plurality of rotatable rollers 402 are arranged inside the slideway bracket 401, and the jig can move in the slideway bracket 401 through the rollers 402. Specifically, when the jig moves on the slideway assembly, the bottom plate kit 302 is located in the slideway bracket 401, and the rollers 402 are respectively arranged on the slideway bracket 401 at both sides of the bottom plate kit 302. Under the action of manpower, the jig can move on the rollers 402, so that the jig can move between the workpiece loading position 601, the workpiece pressing position 602 and the workpiece unloading position 603.
[0041] In a specific embodiment, the low-temperature screen-burning fixture locking tooling further includes a limiting kit, which is used to position the fixture on the slideway assembly when the fixture is at the workpiece pressing position 602. As a preferred method, the limiting kit includes a first limiting member 501 and a second limiting member 502, and the first limiting member 501 and the second limiting member 502 are arranged on the main frame 101 at the workpiece pressing position 602; wherein, when the fixture moves to the workpiece pressing position 602, the output ends of the first limiting member 501 and the second limiting member 502 fix the fixture on the slideway assembly. In an actual application, bayonet slots 3021 are respectively arranged on both sides of the bottom plate kit 302 for accommodating the output ends of the first limiting member 501 and the second limiting member 502 respectively to fix the fixture on the rollers 402. Specifically, when the fixture is pushed from the workpiece loading position 601 to the workpiece pressing position 602, the second limiting member 502 is in an extended state, and the output end of the second limiting member 502 cooperates with a bayonet slot 3021 on one side of the bottom plate kit 302 to limit the fixture from continuing to move towards the workpiece unloading position 603 side. Subsequently, the first limiting member 501 extends, and its output end cooperates with a bayonet slot 3021 on the other side of the bottom plate kit 302, so that the fixture can be fixed at the workpiece pressing position 602 under the action of the two limiting members, realizing the positioning of the fixture on the slideway assembly and ensuring the stability when the pressing device presses the fixture.
[0042] In a specific embodiment, the auxiliary frame 201 includes at least two support rods 2011 and a support plate 2012. The support rods 2011 are fixedly arranged on the main frame 101, and the support plate 2012 is fixedly arranged on the support rods 2011. Among them, preferably, four support rods 2011 are provided, and the support plate 2012 is preferably arranged in a square plate-like structure. The four support rods 2011 respectively correspond to a corner of the support plate 2012. The support rods 2011 and the support plate 2012 can be connected in an integrally formed manner or in a detachable manner, which is not uniquely limited here. It can be understood that the support rods 2011 and the main frame 101 can also be connected in an integrally formed or detachable manner, and the specific connection method can be selected according to the actual application scenario.
[0043] In this embodiment, the pressing-down device includes a pressing-down cylinder 701 and a pressing-down assembly 702.

When the jig moves to the workpiece pressing position 602, the pressing-down cylinder 701 presses the top plate kit 301 with a preset pressing force through the pressing-down assembly 702 to press the jig. It should be noted that when the pressing-down cylinder 701 presses the top plate kit 301 with a preset pressing force, the bolt assembly 304 on the jig is in a relatively loose state. At this time, the staff can use tools such as wrenches to sequentially tighten the bolt assembly 304 to reach the specified torque. After all the bolt assemblies 304 are tightened, the pressing-down cylinder 701 resets, and the second limiting member 502 retracts, pushing the jig to the workpiece unloading position 603. It can be understood that at this time, the first limiting member 501 retracts when the next jig is pushed from the workpiece loading position 601 to the workpiece pressing position 602 to prevent the jig from being blocked by its output end and ensure that the jig is smoothly pushed from the workpiece loading position 601 to the workpiece pressing position 602.
[0044] In a specific embodiment, the control device includes a controller 801. The controller 801 is used to control the operation of the first limiting member 501 and the second limiting member 502 to position the jig when it moves to the workpiece pressing position 602 and release it again at the workpiece pressing position 602 after the jig is tightened. The controller 801 is used to control the operation of the pressing-down cylinder 701 to make the pressing-down assembly 702 press the jig with a preset pressing force and keep pressing the jig with a preset pressing force during the process of tightening the bolt assembly 304. Among them, the first limiting member 501 and the second limiting member 502 are preferably pneumatic telescopic components, such as a pneumatic cylinder with a stopper at the output end. An air pump device for providing power to the pressing-down cylinder 701, the first limiting member 501, and the second limiting member 502 is arranged on the locking tooling. The controller 801 is electrically connected to the air pump device for controlling the operation of the air pump device, and can preset the magnitude of the pressing force of the pressing-down cylinder 701 pressing the jig. The air pump device is respectively connected to the pressing-down cylinder 701, the first limiting member 501, and the second limiting member 502 through a plurality of air valves arranged on the mounting plate 901. And an air pressure regulator 903 is also arranged on the air pump device for controlling the gas flow between the air pump device and the pressing-down cylinder 701, the first limiting member 501, and the second limiting member 502 respectively to realize the communication and operation between the above components. A side chamber 902 for accommodating the air pressure regulator 903 is adaptively arranged on one side of the main frame 101.
[0045] In this embodiment, a pressure display 8011 is arranged on the controller 801 for displaying the pressing force of the pressing-down cylinder 701 pressing the jig, so that the value of the jig pressure can be observed to realize the visualization of the jig pressing force.
[0046] In a specific embodiment, a plurality of telescopic supporting feet 1012 are provided at the bottom of the main frame 101, and a plurality of universal wheels 1013 are provided at the bottom of the main frame 101. Specifically, when the locking tooling needs to be moved, pushing the locking tooling can achieve position adjustment under the action of the universal wheels 1013. After the locking tooling is moved to a suitable position, the supporting feet 1012 are adjusted to separate the universal wheels 1013 from the ground, so as to keep the position of the locking tooling stable and prevent it from shifting during use.
[0047] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principle and purpose of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and all these changes should fall within the protection scope of the claims of the present invention.
