Description

Technical Field

[0001] This utility model relates to a pressure-applying fixture, and more particularly to a pressure-applying fixture for a gravity sensor patch. Background Technology

[0002] A strain gauge is a sensor used to measure stress and strain. It senses external forces or deformations by detecting changes in the resistance of a material and converts these changes into electrical signals. Gravity sensors are also a type of strain gauge. During the manufacturing process, resistance strain gauges need to be attached to areas of large deformation in the elastic body to form a Wheatstone bridge circuit.

[0003] Traditional strain gauges use a single sensor loading method for patch pressurization. However, this method is not only slow but also very labor-intensive, limiting the daily production output of workers. Therefore, existing technologies use specialized tooling for strain gauges. Workers place the tooling at the lower end of a hydraulic filling platform, which applies pressure to the patch on the tooling to ensure a tight fit between the strain gauge and the elastomer. While this significantly reduces the intensity of manual labor, it requires frequent changes of workpieces or tooling. Furthermore, if some patches require pressure holding, the holding time is wasted, limiting the daily production capacity of patches.

[0004] Therefore, this invention aims to provide a pressure-pressurizing fixture for gravity sensors, which can not only mass-produce the patches, but also automatically lock and hold the pressure patches, thereby achieving mass and rapid production. Utility Model Content

[0005] This invention provides a pressure-applying fixture for a gravity sensor patch, which can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A pressure-applying fixture for a gravity sensor patch includes: an outer support frame, a worktable disposed in the middle of the outer support frame, and a placement platform disposed on the worktable; and further includes:

[0008] A batch placement structure includes an operating panel set on a placement platform. A guide component is provided at the upper end of the operating panel. Several stacked fixtures are embedded in the inner side of the guide component. A workpiece is placed between two fixtures. A pressure member is connected to the top of the guide component. When the workpiece is placed into the fixture, pressure is applied to the topmost fixture through the pressure member. A limit member is movably installed on the upper part of the guide component.

[0009] The automatic tightening structure includes a rotating motor located at the top of the inner side of the outer support frame. A pusher is installed at the bottom of the rotating motor, and a rotating head is located below the pusher. After the pusher pushes down, the rotating head cooperates with a limiting member. The rotating motor drives the rotating head to rotate and causes the rotating head to unscrew the limiting member.

[0010] The lower positioning structure includes a mating groove at the bottom of the operating panel and a mating component disposed at the lower end of the placement platform. The mating component is driven by a driving structure.

[0011] As a further improvement, the guide assembly includes a plurality of tightening rods disposed on the operation panel, a positioning rod being disposed between two of the tightening rods, and the pressure-applying member being movably engaged with the tightening rods.

[0012] As a further improvement, the limiting component is a nut, and the tightening rod and the positioning rod are both threaded rods.

[0013] As a further improvement, the inside of the rotating head is set with an internal hexagon, and the rotating head is moved down to engage with the nut.

[0014] As a further improvement, the mating groove is a triangular groove, and the mating component is a triangular rod, which is locked in the triangular groove after being raised.

[0015] As a further improvement, the drive structure is a hydraulic cylinder, which is electrically connected to the pressure-applying component.

[0016] As a further improvement, the operating panel has a lateral opening, and the placement platform is provided with a locating pin on its side.

[0017] The beneficial effects of this utility model are:

[0018] Existing automated patch placement devices rely on manual placement of individual products onto the lower end of the pressing structure for batch processing. However, this method is inefficient, with workers typically only able to process a few hundred products per day. Therefore, this invention utilizes a batch placement structure to place tooling onto the operating panel, followed by a layer of workpieces, and then another layer of tooling. Guided by a guiding component, a stack of tooling layers is formed. After being locked in place by limiting components, the pressure-applying component presses down to create a pressure-holding effect. This allows for the processing of a dozen or twenty workpieces at a time, requiring only one pressure-holding operation. The overall processing efficiency is greatly improved, increasing the processing capacity from nearly a hundred to several hundred products.

[0019] In some existing tooling locking structures, manual locking is often used, which is not only slow but also prone to incomplete locking, resulting in poor pressure holding effect. Therefore, this utility model sets up an automatic tightening structure on the basis of the batch placement structure. After all the tooling is installed, the pusher moves down. After the pusher moves down to the position, the rotating head and the limiting part are engaged. Then, the rotating head is driven by the drive motor to rotate, so that the entire limiting part moves down and presses the topmost tooling, thereby pressing all the tooling.

[0020] After the tooling is locked, pressure needs to be applied to the tooling. After pressure is applied, the tooling needs to be turned and transported. However, during the pressure application stage, the entire operating plate needs to be fixed. Otherwise, if movement occurs, it is easy to damage the tooling or workpiece. Therefore, this utility model uses a lower positioning structure to drive the mating parts upward through a drive structure after the tooling is completely placed, which tightly locks the mating groove and thus locks the entire operating plate. During the pressure application stage, there will be no lateral movement, making it more stable. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

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 this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Reference Figures 1-5As shown, a pressure-applying fixture for a gravity sensor patch includes: an outer support frame 10, a worktable 20 disposed in the middle of the outer support frame 10, a placement platform 30 disposed on the worktable 20, and a batch placement structure 40, including an operating disk 41 disposed on the placement platform 30. A guide assembly 42 is disposed at the upper end of the operating disk 41. A plurality of stacked fixtures 90 are embedded in the inner side of the guide assembly 42. A workpiece is disposed between two fixtures 90. A pressure-applying component 43 is connected to the top of the guide assembly 42. When a workpiece is placed into a fixture 90, pressure is applied to the topmost fixture 90 through the pressure-applying component 43. The guide assembly 42 is movably mounted with a limiting member 44; the automatic tightening structure 50 includes a rotating motor 51 located at the top of the inner side of the outer support frame 10, a pushing member 52 is mounted at the bottom of the rotating motor 51, and a rotating head 53 is located below the pushing member 52. After the pushing member 52 pushes down, the rotating head 53 cooperates with the limiting member 44, and the rotating motor 51 drives the rotating head 53 to rotate and unscrew the limiting member 44; the lower positioning structure 60 has a mating groove at the bottom of the operating disk 41, and the lower positioning structure 60 includes a mating member 61 located at the lower end of the placement platform 30, and the mating member 61 is driven by a driving structure 62.

[0032] Existing automatic patch placement devices rely on manual placement of individual products onto the lower end of the pressing structure for batch processing. However, this method is inefficient, with workers typically only able to process a few hundred products per day. Therefore, this invention utilizes a batch placement structure 40 to place tooling 90 onto the operating panel 41, followed by another layer of workpieces, and then another layer of tooling. Guided by the guide component 42, a stack of tooling layers is formed. After being locked and fixed by the limiting component 44, the pressure component 43 applies pressure to create a pressure-holding effect. This allows for the processing of a dozen or twenty workpieces at a time, requiring only one pressure holding operation, significantly improving overall processing efficiency and increasing the processing volume from nearly a hundred to several hundred.

[0033] During the guiding process of the guide assembly 42, in order to standardize the position of the entire fixture and thus improve the accuracy of workpiece installation, the guide assembly 42 includes several tightening rods 421 set on the operation panel 41. A positioning rod 422 is set between two of the tightening rods 421. The pressure member 43 is movably engaged with the tightening rods 421, so that the four corners of the fixture 90 are engaged with the tightening rods 421, and the side wall of the fixture 90 is attached to the positioning rod 422, thereby forming a multi-faceted positioning.

[0034] In this embodiment, the limiting member 44 is a nut, and the tightening rod 421 and the positioning rod 422 are both threaded rods, thereby achieving threaded clamping fit.

[0035] In some existing tooling 90 locking structures, manual locking is often used. This locking method is not only slow, but also prone to incomplete locking, resulting in poor pressure holding effect. Therefore, this utility model sets up an automatic tightening structure 50 on the basis of the batch placement structure 40. After all the tooling 90 is installed, the pusher 52 is moved down. After the pusher 52 moves down into place, the rotating head 53 and the limiting member 44 are engaged. Then, the rotating head 53 is driven to rotate by the drive motor 51, so that the entire limiting member 44 moves down and presses the topmost tooling 90, thereby pressing all the tooling 90.

[0036] In order to achieve the cooperation between the rotating head 53 and the limiting member 44, the interior of the rotating head 53 is set with an internal hexagon. After the rotating head 53 moves down, it cooperates with the nut, so that the rotating head 53 can be driven to move by rotating the motor 51.

[0037] After the fixture 90 is locked, pressure needs to be applied to the fixture 90. After pressure is applied, the fixture 90 needs to be turned and transported. However, during the pressure application stage, the entire operating plate 41 needs to be fixed. Otherwise, if movement occurs, it is easy to damage the fixture 90 or the workpiece. Therefore, this utility model uses a lower positioning structure 60 to drive the mating part 61 upward through the drive structure 62 after the fixture 90 is completely placed, which tightly locks the mating groove and thus locks the entire operating plate 41. During the pressure application stage, there will be no lateral movement, making it more stable.

[0038] In this embodiment, the mating groove is a triangular groove, and the mating component 61 is a triangular rod. After the triangular rod rises, it is locked in the triangular groove, and the movement of the entire operating panel 41 can be restricted by the triangular rod.

[0039] In order to completely stabilize the operating plate 41 and prevent the heavy operating plate 41 from affecting the mating part 61, the operating plate 41 has a side opening, and the placement platform 30 is provided with a positioning pin 63 on the side. The operation plate 41 can be stabilized by the cooperation between the placement platform 30 and the operating plate 41.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
