Abstract
Description
Technical Field
[0001] The present application relates to the technical field of thrust detection, and in particular to a thrust testing device. Background Art
[0002] Thrust test is an important item of product function test, especially in the assembly of electronic product structural parts, there are many small parts for dispensing or laser welding, and thrust test is needed to determine whether the adhesion or welding force meets the standard. At present, for random inspection test items, special thrust fixtures are used in conjunction with thrust equipment for testing, and for small thrust test items that need to be fully inspected on the production line, thrust pens with compression spring structures are generally used for full inspection.
[0003] However, the output force of the thrust pen with a general compression spring structure cannot be accurately controlled. During inspection, the operator is required to push the workpiece with the thrust pen to compress the spring until it corresponds to the position of the marking groove on the thrust pen. This process requires visual control by the operator, which is difficult to operate and has low measurement accuracy. In addition, different operators will produce different results due to different operating methods during inspection. Utility Model Content
[0004] In view of the above, it is necessary to propose a thrust testing device that can accurately control the thrust size and has the advantages of low operating difficulty and high detection accuracy.
[0005] The embodiment of the present application provides a thrust testing device, comprising: an inner shell, provided with a sliding hole and two adjustment holes, the sliding hole comprising a first end and a second end opposite to each other, the two adjustment holes being arranged on both sides of the sliding hole in a mirror-symmetrical manner with respect to the extension direction of the sliding hole and both being connected to the sliding hole, and a preset angle being formed between the extension direction of the two adjustment holes and the extension direction of the sliding hole; a thrust assembly, arranged in the inner shell, the thrust assembly comprising a sliding member slidably arranged in the sliding hole, the end of the sliding member extending out of the first end of the sliding hole being used for resisting a workpiece, and the end of the sliding member close to the second end of the sliding hole having two The invention relates to a plurality of inclined surfaces, the two inclined surfaces are mirror-symmetrically arranged relative to the extension direction of the sliding hole and face the corresponding adjustment holes respectively; and two adjustment components are respectively arranged in the two adjustment holes, each of the adjustment components comprises a first push member, a first elastic member and a first adjustment member, the first push member is slidably arranged in the adjustment hole and abuts against the corresponding inclined surface, the first elastic member is arranged between the first push member and the first adjustment member and are respectively connected to the first push member and the first adjustment member, the first adjustment member approaches or moves away from the first push member to adjust the thrust of the first push member on the sliding member through the first elastic member.
[0006] When the thrust test device is used for testing, the sliding member abuts against the testing position of the workpiece, and then an external force is applied to make the sliding member slide from the first end to the second end relative to the sliding hole. The first elastic members in the two adjustment components both abut against the corresponding first push members, and then apply elastic force to the sliding member through the inclined surface. When the thrust reaches the extreme value, the two first push members both leave the corresponding inclined surface and abut against the side of the sliding member, thereby reducing the force applied by the adjustment component to the sliding member, so that the sliding member continues to slide along the sliding hole under the action of a force less than the extreme value. In this way, the operator only needs to press the inner shell when the sliding member abuts against the workpiece to detect whether the workpiece meets the requirements when the extreme force is applied. The operation is simple and the detection accuracy is high. By adjusting the position of the first adjustment member in the adjustment hole, the magnitude of the force applied by the first elastic member and the first push member to the sliding member can be adjusted.

In addition, in the description of the present application, it should be noted that the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0061] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication, it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.
[0062] The embodiments of the present application are further described below in conjunction with the accompanying drawings.
[0063] See also Figure 1 and Figure 2The present application provides a thrust test device 100 for detecting the magnitude of thrust that a workpiece (not shown) can withstand. The workpiece may be a structural member pasted or welded to other structures. The thrust test device 100 includes an inner shell 10, a thrust component 20, and two adjustment components 30.
[0064] Specifically, see Figure 2 and Figure 3 The inner shell 10 is provided with a sliding hole 11 and two adjustment holes 12. The sliding hole 11 includes a first end 111 and a second end 112 opposite to each other. The two adjustment holes 12 are arranged on both sides of the sliding hole 11 in a mirror-symmetrical manner relative to the extension direction of the sliding hole 11 and are both connected to the sliding hole 11. The extension direction of the two adjustment holes 12 forms a preset angle with the extension direction of the sliding hole 11. The inner shell 10 can be a plate-like structure, with a sliding hole 11 penetrating the inner shell 10 in the middle, and two adjustment holes 12 are arranged on both sides of the sliding hole 11. Alternatively, the inner shell 10 is a special-shaped structure, including a main body 13 and two adjustment parts 14 connected to each other. The sliding hole 11 is arranged in the main body 13 and penetrates the main body 13. The two adjustment parts 14 are symmetrically arranged on both sides of the main body 13. The two adjustment holes 12 are respectively arranged in the two adjustment parts 14, which is conducive to reducing the volume of the inner shell 10 and is convenient for operators to use. It can be understood that one end of the adjustment hole 12 is connected to the sliding hole 11, and the other end is connected to the outside.
[0065] See also Figure 2 , Figure 3 and Figure 4 The push assembly 20 is disposed in the inner shell 10. The push assembly 20 includes a sliding member 21 slidably disposed in the sliding hole 11. The end of the sliding member 21 extending out of the first end 111 of the sliding hole 11 is used to resist the workpiece. The end of the sliding member 21 close to the second end 112 of the sliding hole 11 has two inclined surfaces 211. The two inclined surfaces 211 are mirror-symmetrically disposed relative to the extending direction of the sliding hole 11 and face the corresponding adjustment holes 12 respectively. The sliding member 21 can be a columnar structure. In order to prevent the sliding member 21 from rotating around the axis during use, the cross section of the sliding member 21 can be set to a rectangle, or a section can be set on the sliding member 21. It can be understood that the cross section of the sliding hole 11 is adapted to the cross section of the sliding member 21.
[0066] Two adjustment components 30 are respectively arranged in two adjustment holes 12, and each adjustment component 30 includes a first push member 31, a first elastic member 32 and a first adjustment member 33. The first push member 31 is slidably arranged in the adjustment hole 12 and abuts against the corresponding inclined surface 211. The first elastic member 32 is arranged between the first push member 31 and the first adjustment member 33, and is respectively connected to the first push member 31 and the first adjustment member 33. The first adjustment member 33 approaches or moves away from the first push member 31 to adjust the thrust of the first push member 31 on the sliding member 21 through the first elastic member 32. The first push member 31 can be set as a columnar structure, which can slide in the adjustment hole 12. In order to improve the stability of the first push member 31 when sliding in the adjustment hole 12, the cross section of the first push member 31 can be a rectangle, and the cross section of the adjustment hole 12 is a rectangle that matches the first push member 31. The first elastic member 32 can be a spring, etc., and the first adjustment member 33 can be a headless bolt, etc. It can be understood that by adjusting the position of the headless bolt in the adjustment hole 12 , the first elastic member 32 can be squeezed to adjust the force applied by the first elastic member 32 to the first push member 31 , thereby changing the maximum force of the first push member 31 on the sliding member 21 .
[0067] When the thrust test device 100 provided by the present application is used for testing, the sliding member 21 abuts against the testing position of the workpiece, and then an external force is applied to make the sliding member 21 slide from the first end 111 to the second end 112 relative to the sliding hole 11, and the first elastic members 32 in the two adjustment components 30 both abut against the corresponding first abutting members 31, thereby applying elastic force to the sliding member 21 through the inclined surface 211. When the thrust reaches the extreme value, the two first abutting members 31 both leave the corresponding inclined surface 211 and abut against the side of the sliding member 21, thereby reducing the force applied by the adjustment component 30 to the sliding member 21, so that the sliding member 21 continues to slide along the sliding hole 11 under the action of a force less than the extreme value. In this way, the operator only needs to press the inner shell 10 when the sliding member 21 abuts against the workpiece to detect whether the workpiece meets the requirements when the extreme force is applied, which is simple to operate and has high detection accuracy. By adjusting the position of the first adjusting member 33 in the adjusting hole 12, the magnitude of the force exerted by the first elastic member 32 and the first pushing member 31 on the sliding member 21 can be adjusted. Before testing, the extreme value measured by the thrust testing device 100 can be set by adjusting the adjusting component 30.
[0068] In some embodiments, see Figure 1 , Figure 2 and Figure 3The thrust test device 100 further includes a housing 40, the housing 40 is provided with a receiving groove 41 adapted to the structure of the inner housing 10, the inner housing 10 is detachably arranged in the receiving groove 41, and a first through hole 42 is provided at one end of the housing 40 corresponding to the sliding hole 11, and the end of the sliding member 21 extending out of the sliding hole 11 passes through the first through hole 42. The structure of the housing 40 is adapted to the structure of the inner housing 10, and can be a special-shaped structure, and the structure of the receiving groove 41 is adapted to the structure of the inner housing 10 to accommodate the inner housing 10. It can be understood that the end of the adjustment hole 12 away from the sliding hole 11 is connected to the outside world, so as to adjust the position of the first adjustment member 33 in the adjustment hole 12. Before using the thrust test device 100, it is necessary to adjust the position of the first adjustment member 33 under the detection of an external force measuring device (not shown), so as to set the extreme value detected by the thrust test device 100. When using the thrust test device 100, the operator does not need to adjust the position of the first adjustment member 33. In order to prevent the operator from changing the position of the first adjustment member 33 by mistake, thereby changing the measurement extreme value of the thrust test device 100, after the inner shell 10 is installed on the outer shell 40, the outer shell 40 closes the adjustment hole 12. When the extreme value needs to be adjusted or calibrated, the inner shell 10 is removed from the outer shell 40, and then the adjustment assembly 30 is adjusted.
[0069] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The thrust testing device 100 also includes a reset assembly 50 for pushing the sliding member 21 to move toward the first end 111. The reset assembly 50 includes a second push member 51, a second elastic member 52, a second adjusting member 53 and a locking member 54. The locking member 54 is adjacent to the second end 112 of the sliding hole 11 and is connected to the housing 40. The locking member 54 is provided with a threaded hole 541 arranged along the extension direction of the sliding hole 11 and connected to the sliding hole 11. The second push member 51 is arranged at the second end 112 of the sliding hole 11 and abuts against the sliding member 21. The second adjusting member 53 is arranged in the threaded hole 541. The second elastic member 52 is arranged between the second push member 51 and the second adjusting member 53 and is respectively connected to the second push member 51 and the second adjusting member 53. The second adjusting member 53 approaches or moves away from the second push member 51 to adjust the thrust of the second push member 51 on the sliding member 21 through the second elastic member 52. The second push member 51 may be a columnar structure, and the cross section of the second push member 51 matches the cross section structure of the sliding hole 11. The second elastic member 52 may be a spring, etc., the second adjustment member 53 may be a headless bolt, etc., the positioning member 54 may be detachably connected to the housing 40 by bolts, etc., and the threaded hole 541 passes through the positioning member 54.
[0070] When measuring force, the sliding member 21 abuts against the detection position, and the operator holds the housing 40 and pushes it toward the detection position. At this time, the sliding member 21 moves from the first end 111 of the sliding hole 11 to the second end 112. By setting the reset assembly 50, after the detection is completed, the second elastic member 52 and the second push member 51 can push the sliding member 21 from the second end 112 of the sliding hole 11 to the first end 111, so as to reset the sliding member 21. It can be understood that the elastic force of the second elastic member 52 is less than the elastic force of the first elastic member 32. When resetting, the first push member 31 abuts against the side of the sliding member 21. At this time, when the sliding member 21 moves from the second end 112 to the first end 111, there is friction between the sliding member 21 and the first push member 31. As long as the force exerted by the second elastic member 52 on the sliding member 21 through the second support member is greater than the friction between the two first push members 31 and the sliding member 21, the reset assembly 50 can push the sliding member 21 to reset. By adjusting the position of the second adjusting member 53 in the threaded hole 541 , the force exerted by the second elastic member 52 on the second pushing member 51 can be changed.
[0071] In some embodiments, see Figure 2 The housing 40 is provided with a second through hole 43 arranged along the extension direction of the threaded hole 541, and the second through hole 43 is connected with the threaded hole 541. By providing the second through hole 43, it is convenient for the operator to adjust the position of the second adjustment member 53 in the threaded hole 541, and timely adjustment can be made if the force of the reset assembly 50 is insufficient to push the sliding member 21 to reset during use.
[0072] In some embodiments, see Figure 2 and Figure 4 The locking member 54 is provided with a locking protrusion 542, and the accommodating groove 41 is provided with a limiting portion 411 adapted to the locking protrusion 542. The limiting portion 411 is provided adjacent to the second through hole 43, and the locking protrusion 542 is engaged with the limiting portion 411 so that the locking member 54 is fixedly arranged in the accommodating groove 41. By providing the locking protrusion 542 in the limiting portion 411, the position of the locking member 54 can be limited, and the position of the locking member 54 is prevented from changing, which affects the second elastic member 52 from pushing the sliding member 21 to reset through the second pushing member 51.
[0073] In some embodiments, see Figure 2The end of the second push member 51 that abuts the sliding member 21 is provided with a contact portion 511, and the end of the first push member 31 that abuts the inclined surface 211 is provided with a avoidance groove 311 that matches the contact portion 511, and the avoidance groove 311 is used to avoid the contact portion 511. It can be understood that the second push member 51 always abuts the sliding member 21 during use. When the first push member 31 abuts the inclined surface 211 of the sliding member 21, the avoidance groove 311 is provided on the first push member 31, so that the contact portion 511 of the second push member 51 can be avoided, thereby preventing the first push member 31 and the second push member 51 from abutting against each other during movement, thereby affecting the movement of the adjustment component 30 and the reset component 50.
[0074] In some embodiments, see Figure 2 and Figure 3 The included angle between the extending direction of the adjusting hole 12 and the extending direction of the sliding hole 11 from the first end 111 to the second end 112 is in the range of 30°-70°. The included angle between the extending direction of the adjusting hole 12 away from the sliding hole 11 and the extending direction of the sliding hole 11 from the first end 111 to the second end 112 is as follows: Figure 3 The angle a in the figure can be 30°, 40°, 50°, 60° or 70°, and can also be any angle between 30° and 70°, which are not listed here. Preferably, the included angle between the extending direction of the adjustment hole 12 away from the sliding hole 11 and the extending direction of the sliding hole 11 from the first end 111 to the second end 112 is 60°.
[0075] In some embodiments, see Figure 1 and Figure 2 The push assembly 20 also includes a push head 22, which is detachably connected to the end of the sliding member 21 away from the first push member 31, and the push head 22 is used to support the workpiece. The push head 22 and the sliding member 21 can be connected in a threaded manner. By setting the push head 22, the push head 22 can be directly replaced after being worn out due to repeated use, so as to reduce maintenance costs. By installing push heads 22 of different structures on the sliding member 21, it can be applied to a variety of application scenarios and improve applicability. The material of the push head 22 can be made of materials such as PU, so that the push head 22 can be prevented from rigidly contacting with the workpiece to damage the workpiece.
[0076] In some embodiments, see Figure 1 and Figure 2The end of the sliding member 21 extending out of the sliding hole 11 is provided with a reset hole 212, and the reset hole 212 is used to be inserted by an external structural member (not shown) to guide the movement of the sliding member 21. The reset hole 212 can be a through hole that penetrates the sliding member 21. By providing the reset hole 212, when the sliding member 21 is stuck in the sliding hole 11 and cannot be reset, an external structural member such as a screwdriver, a pin, etc. can be inserted into the reset hole 212, and then the sliding member 21 can be pulled out of the sliding hole 11 by external force to reset the sliding member 21.
[0077] In some embodiments, see Figure 2 , Figure 4 and Figure 5 The sliding member 21 is provided with a waist-shaped hole 213, and the outer shell 40 is connected with a stop pin 44 that penetrates the outer shell 40 and the inner shell 10 and is inserted into the waist-shaped hole 213. The stop pin 44 is inserted into the waist-shaped hole 213 to limit the sliding member 21. Through the cooperation between the stop pin 44 and the waist-shaped hole 213, the sliding member 21 can be prevented from sliding out of the first end 111 of the sliding hole 11, and the distance that the sliding member 21 moves toward the second end 112 in the sliding hole 11 can be limited, so as to prevent the sliding member 21 from moving too far toward the second end 112 of the sliding hole 11, thereby damaging the reset assembly 50.
[0078] The working process of the thrust testing device 100 provided in the embodiment of the present application is roughly as follows:
[0079] When performing thrust tests, refer to Figure 1 , Figure 2 and Figure 6 The operator holds the housing 40, places the push head 22 against the position of the workpiece to be tested, and then pushes the housing 40 toward the workpiece. Figure 7 At this time, the sliding member 21 moves from the first end 111 to the second end 112 in the sliding hole 11, and pushes the two first push members 31 to move through the two inclined surfaces 211. The first push members 31 compress the first elastic member 32, and the first elastic member 32 applies force to the sliding member 21 through the first push members 31. At the same time, the sliding member 21 pushes the second push member 51 to move, and the second elastic member 52 is compressed under the push action of the second push member 51.
[0080] During the test, please refer to Figure 8As the sliding member 21 continues to move in the sliding hole 11, the first push member 31 slides relative to the inclined surface 211, and the force exerted by the first elastic member 32 on the sliding member 21 through the first push member 31 continues to increase until the first push member 31 contacts the intersection of the inclined surface 211 and the side of the sliding member 21. The force exerted by the first elastic member 32 and the first push member 31 on the sliding member 21 reaches the maximum, which is the test extreme value. If the binding force of the tested part of the workpiece is greater than the extreme value of the thrust test device 100, the operator continues to push the housing 40 to move during the test. Please refer to Fig. 9 When the force pushing the housing 40 exceeds the extreme value, the first push member 31 moves from the inclined surface 211 to the side of the sliding member 21. At this time, the force of the first push member 31 on the sliding member 21 is reduced, and only the friction force between the first push member 31 and the sliding member 21 remains. If the housing 40 continues to move, the force of the sliding member 21 on the workpiece will not be greater than the extreme value.
[0081] If the tested part of the workpiece falls off before the thrust testing device 100 reaches the extreme value, it means that the bonding force of the tested part of the workpiece is less than the extreme value of the thrust testing device 100, and the tested workpiece is unqualified.
[0082] After the test is completed, the thrust test device 100 is moved away from the detection position, and the second elastic member 52 in the reset assembly 50 pushes the sliding member 21 through the second push member 51 to reset the sliding member 21. After the test is completed, if the reset assembly 50 cannot push the sliding member 21 to reset, the elastic force of the second elastic member 52 on the second push member 51 and the sliding member 21 can be increased by adjusting the position of the second adjustment member 53, so that the sliding member 21 can be reset.
[0083] When the extreme value of the thrust test device 100 needs to be adjusted, the inner shell 10 is removed from the outer shell 40, and the position of the first adjustment member 33 in the two adjustment assemblies 30 is adjusted to change the magnitude of the force exerted by the first elastic member 32 on the first push member 31. During the adjustment, the push head 22 can be abutted against an external force measuring device to detect the extreme value that the thrust test device 100 can reach. After the adjustment is completed, the inner shell 10 can be installed in the receiving groove 41 of the outer shell 40 for use.
