[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Reference Figures 1 to 5According to a preferred embodiment of the present invention, a force detection device includes: a movable base 10; a tooling device disposed on the base 10 for fixing the workpiece to be tested; a force gauge 30 movably disposed on the base 10 and corresponding to the tooling device; a driving device 40 disposed on the base 10 for driving the force gauge 30 to move back and forth in the direction of approaching and moving away from the tooling device; the driving device 40 has an operating part 41 for manually controlling its operation. This force value detection device uses a movable base 10, which can be moved closer to the production line during use, shortening the handling distance of the workpiece to be tested. It uses a small and lightweight force gauge 30 that is easy to operate to detect the force value of the workpiece. During use, simply fix the workpiece on the tooling device, and then operate the operating unit 41 to make the drive device 40 drive the force gauge 30 to move, thereby detecting the force value of the workpiece. After the test is completed, the workpiece is removed from the tooling device, thus completing the force value detection process. The device has a simple structure, is easy to operate, and can effectively shorten the detection time, improve detection efficiency, reduce the labor intensity of workers, and reduce the probability of the workpiece being damaged by bumps during handling, which helps to ensure product quality.

[0024] The force gauge 30 in this utility model is an existing product with a variety of commonly used structures and specifications. It can be used to detect the magnitude of tensile and compressive forces. Its structure and principle are well known to those skilled in the art, and it can be flexibly selected as needed.

[0025] As a preferred embodiment of this utility model, it may also have the following additional technical features: Reference Figure 1 , Figure 3 and Figure 4 In this embodiment, the drive device 40 is a manually driven mechanism without a power structure, which helps to simplify the structure and eliminates the need for a power source or external power source, facilitating the movement and use of the force detection device. In other embodiments, the drive device 40 may also adopt a power structure such as a cylinder, motor, or hydraulic cylinder, and be driven by an external power source, air source, or built-in battery. Correspondingly, its operating part 41 can be a button, control panel, or other common control structure.

[0026] In this embodiment, the driving device 40 is a linkage mechanism, and the operating part 41 is a long-handled handle that can be swung on the base 10 and connected to the linkage mechanism. This design is simple and reliable, easy to manufacture and use, and helps reduce the size and weight of the force detection device, facilitating movement. The long-handled handle also makes operation easier and more flexible for workers. In this embodiment, the driving device 40 includes a first connecting rod 42, a second connecting rod 43, and a connecting rod 44. The connecting rod 44 slides through the base 10 and is connected to the force gauge 30. The first end of the first connecting rod 42 is pivotally connected to the base 10, and the tail end is pivotally connected to the first end of the second connecting rod 43. The tail end of the second connecting rod 43 is pivotally connected to the connecting rod 44. The long-handled handle is connected to or integrated with the second connecting rod 43. Therefore, by moving the long-handled handle, the connecting rod 44 can be driven to move, thereby moving the force gauge 30. In other embodiments, the linkage mechanism may also adopt other suitable linkage structures, or the drive device 40 may also adopt other suitable structures such as gear and rack mechanism, worm gear mechanism, lead screw mechanism, eccentric wheel mechanism, etc. to drive the force gauge 30 to move. Those skilled in the art can flexibly choose according to needs, and its corresponding operating part 41 may also be a handwheel or other corresponding operating structure, and is not limited to this.

[0027] Those skilled in the art will understand that the long handle in this utility model utilizes the lever principle to reduce the amount of force required by the worker during operation. Its length can be calculated and adjusted according to factors such as testing conditions, testing requirements, and the average physical fitness of the operator. Under different conditions and requirements, the appropriate length varies greatly, and it can often be arbitrarily selected within a certain length range.

[0028] Reference Figure 1 and Figure 3 In this embodiment, the force gauge 30 is vertically movable and mounted on the base 10. A buffer seat 51 is provided on the force gauge 30, and a buffer 52 is provided on the base 10 below the buffer seat 51. This buffer provides cushioning during the force gauge 30's descent, preventing it from falling too quickly and causing malfunction or damage. The buffer 52 is widely used; it slows down the movement of objects through a damping structure and has common specifications such as hydraulic, pneumatic, and elastic structures. This embodiment uses a hydraulic buffer 52; in other embodiments, those skilled in the art can also choose buffers 52 with other structures and specifications.

[0029] In this embodiment, the force gauge 30 is provided with an indexing pin 53, and the base 10 is correspondingly provided with a limiting pin hole 54. The indexing pin 53 has a pin rod. When the force gauge 30 moves to a predetermined position, the indexing pin 53 aligns with the limiting hole and inserts the pin rod into the limiting pin hole 54 to limit the downward movement of the force gauge 30. This avoids the force gauge 30 from being damaged due to the worker habitually letting go after lifting the force gauge, which would require the worker to unlock the indexing pin 53 to allow the force gauge 30 to move downward. This helps reduce malfunctions and damage caused by misoperation, effectively extending its service life and reducing the failure rate. The indexing pin 53 has a wide range of applications, and its structure and principle are well known to those skilled in the art, so they will not be described in detail here. It should be noted that setting a separate pin, pin hole, and corresponding reset structure can also achieve the same effect as the indexing pin 53. However, such structures are similar to the structure and principle of the indexing pin 53 and can be considered as a disassembly of the indexing pin 53. They should be regarded as equivalent structures to the indexing pin 53. In other embodiments, the positions of the indexing pin 53 and the limiting pin hole 54 on the force gauge 30 and the base 10 can also be interchanged.

[0030] In this embodiment, a sliding seat 55 is slidably mounted on the base 10. The force gauge 30 is mounted on the sliding seat 55. A protrusion on the side of the sliding seat 55 serves as a buffer seat 51 corresponding to the buffer 52. An indexing pin 53 is also mounted on the buffer seat 51. This embodiment employs both the indexing pin 53 and the buffer 52. The combination of these two effectively prevents malfunctions and damage to the force gauge 30 caused by accidental operation and impact from a rapid fall, making it more reliable and helping to further extend its service life and reduce the failure rate. Furthermore, in this embodiment, the sliding seat 55 is slidably mounted on the base 10 via a first dovetail slide rail mechanism 56, which provides a good guiding effect for the sliding seat 55, ensuring stable movement of the force gauge 30 and preventing deflection of the force gauge 30 that could affect the detection structure. This helps to simplify the structure and ensure the accuracy of the detection results. In other embodiments, the force gauge 30 can also be directly slidably mounted on the base 10. The force gauge 30 or the sliding seat 55 can also be movably mounted on the base 10 using other commonly used structures such as a sliding rod sleeve structure or a pulley and slide rail mechanism. Those skilled in the art can flexibly select and adjust as needed, and are not limited to these methods. Furthermore, in this embodiment, a vertical support 57 is installed on the base 10, and the sliding seat 55 is movably mounted under this support 57, facilitating manufacturing. In other embodiments, the shape of the base 10 can also be flexibly adjusted as needed, and the movement direction of the force gauge 30 can be selected as horizontal, inclined, or other suitable directions, and is not limited to these methods.

[0031] In this embodiment, the limiting pin hole 54 is disposed on a hole seat 11, and the hole seat 11 is provided with a guide slope 58. The guide slope 58 is used to push the pin of the indexing pin 53 to move away from the limiting pin hole 54 as the force gauge 30 moves upward. The indexing pin 53 has a reset structure for driving the pin to move towards the limiting pin hole 54. Thus, during the upward movement of the force gauge 30, the pin of the indexing pin 53 can be automatically pushed away from the hole seat 11. When the pin is aligned with the limiting pin hole 54, the reset structure can automatically push the pin back into the limiting pin hole 54. This process does not require operation of the indexing pin 53, which is convenient for operation and use. The reset structure often adopts elastic structures such as springs, spring sheets, and spring arms. Of course, other reset structures such as magnetic structures can also be used. The reset structure is also a structure that is built into most indexing pins 53, and will not be described in detail here. In other embodiments, a guide slope 58 can be provided on the pin of the indexing pin 53, or guide slopes 58 can be provided on both the pin and the hole seat 11, which can also achieve the effect of pushing the pin to move. In this embodiment, the indexing pin 53 includes a pull handle 531, which makes it convenient for the worker to pull the pin of the indexing pin 53 to disengage the pin from the limiting pin hole 54. In other embodiments, the indexing pin 53 can also adopt other commonly used specifications and structures, which can be flexibly selected by those skilled in the art as needed.

[0032] Reference Figure 1 , Figure 2 and Figure 5 In this embodiment, the tooling device includes a support block 21 and a manual self-locking clamp 22 corresponding to the support block 21. The manual self-locking clamp 22 is used to press the workpiece to be tested onto the support block 21. It has a simple structure, is easy to operate, and can quickly press, fix, and unlock the workpiece, further improving testing efficiency. The manual self-locking clamp 22 is widely used and is typically driven by a linkage structure. Self-locking is achieved through the design of the rod's tilt angle. In addition, there are various other commonly used structures and specifications, the structures and principles of which are well known to those skilled in the art. Those skilled in the art can flexibly choose according to their needs, and these will not be detailed here. In other embodiments, the tooling device can also adopt other commonly used tooling structures such as latches, bolt-locked clamps, and elastic clamps, or it can adopt a clamp structure with an actuator driven by electricity, compressed air, etc. Those skilled in the art can flexibly choose according to their needs and are not limited to these.

[0033] In this embodiment, the tooling device also includes two positioning platforms 23 respectively disposed on both sides of the support block 21. The positioning platforms 23 are provided with positioning grooves 24 adapted to the test piece, which are suitable for fixing and testing long test pieces such as automotive door and window guide rails.

[0034] In this embodiment, the support block 21 is movably mounted on the base 10, and the movable direction of the support block 21 is perpendicular to the movable direction of the force gauge 30. The manual self-locking clamp 22 is located in the movable direction of the support block 21. This allows for flexible adjustment of the fixed position of the test piece, facilitating the switching between applying pressure or tension to the test piece for different force values. It also makes it easier to adapt to different test pieces, making it more flexible and convenient to use. Moreover, since the movable direction of the support block 21 is perpendicular to that of the force gauge 30, the force applied to the test piece during force value detection will not cause the support block 21 to move. This eliminates the need for a fixing structure for the support block 21, further simplifying the structure and facilitating operation. It also helps to further shorten the detection time and improve detection efficiency. In this embodiment, the support block 21 is mounted on the base 10 via a second dovetail slide rail mechanism, ensuring the stability of the support block 21 and preventing it from shifting or deviating, which could affect the testing operation and results. An operating rod 25 is connected to the support block 21, allowing for easy pushing and pulling to move it, facilitating operation. In other embodiments, the support block 21 can also be movably mounted on the base 10 using other common structures such as a slide bar sleeve mechanism or a pulley structure. Alternatively, the support block 21 can simply be placed on the base 10 and moved. Alternatively, the position of the support block 21 can be adjusted by driving it to move using other common structures such as a lead screw mechanism or a rack and pinion mechanism. Furthermore, common locking structures such as locking screws, snap-fit ​​structures, or pin structures can be added to fix the support block 21. Alternatively, the support block 21 can be mounted on the base 10 using a fixed or detachable structure, allowing those skilled in the art to flexibly choose the appropriate adjustment method as needed.

[0035] In this embodiment, a contour block 26 is also placed on the support base. The contour block 26 is adapted to the shape of the test piece and works with the manual self-locking clamp 22 to clamp the test piece, which can ensure the firm fixation of the test piece. Different contour blocks 26 can be replaced according to different test pieces or testing requirements, making it more flexible and convenient to use and with a wider range of applications.

[0036] In this embodiment, the tooling device is detachably mounted on the base 10, facilitating the replacement of different tooling devices to adapt to the fixing needs of different test pieces, making it more flexible and convenient to use, and with a wider range of applications. In this embodiment, the tooling device is detachably mounted on the base 10 by screws, making it more secure and reliable. The screws are equipped with a handle 28 for easy manual tightening and loosening, making assembly and disassembly more convenient. In other embodiments, the tooling device can also be detachably mounted on the base 10 using other commonly used detachable structures such as snap-fits, latches, or clamps. In addition, in this embodiment, the tooling device also includes a base 27, on which the support block 21, positioning platform 23, and manual self-locking clamp 22 are mounted, facilitating overall assembly and disassembly and improving replacement efficiency. In other embodiments, the various parts of the tooling device can also be detachably mounted on the base 10 separately, allowing for the replacement of corresponding components as needed, and is not limited to this.

[0037] In this embodiment, the tooling device is provided with positioning pin holes, and the base 10 is correspondingly provided with positioning pins 59. The positioning pins 59 are inserted into the positioning pin holes, which can accurately position the tooling device, helping to ensure the accuracy of the position of the tooling device and the workpiece under test, and thus helping to ensure the accuracy of the test results. In this embodiment, there are two positioning pin holes and two positioning pins 59, which are respectively located on both sides of the base 27 along its length. In other embodiments, the positions of the positioning pin holes and the positioning pins 59 can be interchanged, and the number and distribution of the positioning pin holes and the positioning pins 59 can also be flexibly adjusted as needed, and are not limited thereto.

[0038] Reference Figure 1 and Figure 5 In this embodiment, the base 10 is mounted on a vehicle body 60, and the bottom of the vehicle body 60 has casters 61. This design is simple in structure, easy to manufacture, and allows the force detection device to be moved to any desired position, making it more flexible and convenient to use. The casters 61 have a locking structure, facilitating the fixation of the force detection device during the detection process, thus simplifying operation and use. Casters 61 with locking structures are widely used, and those skilled in the art can choose according to their needs. In other embodiments, the base 10 can also be mounted on a slide rail or other structure to make the base 10 movable. Since the force detection device has a relatively simple structure, small size and weight, and is easy to transport, the base 10 can also be moved directly.

[0039] This embodiment is applicable to the force value detection of automotive door and window tracks. This utility model can be used for force value detection in the production of various suitable parts in automobiles.

[0040] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0041] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
