Abstract
Description
Technical Field
[0001] This application relates to the field of posture adjustment technology, and in particular to a posture adjustment device. Background Technology
[0002] The measurement and control of a mass flow controller is related to its installation angle, requiring parameter adjustments based on different installation angles (such as -90°, 0°, +90°, etc.). Therefore, a suitable position adjustment device is needed to conveniently control the installation angle of the mass flow controller in order to calibrate its various parameters under different installation angles.
[0003] Current posture adjustment devices generally include a base, a slide, and a drive mechanism. The drive mechanism is located between the base and the slide to drive the slide to move relative to the base, thereby adjusting the product fixed on the slide.

[0052] The first aspect of this application provides a pose adjustment device. Please refer to... Figure 1 and Figure 5 The posture adjustment device 100 includes a base 10, a positioning seat 20, and a clamp 30. The base 10 is used to fix it on the worktable. The base 10 is provided with multiple sets of slots 40 arranged along the first direction X. The positioning seat 20 can be inserted into the multiple sets of slots 40 to adjust the angle of the positioning seat 20. The clamp 30 is provided on the positioning seat 20 and is used to clamp the product 200 to be tested.
[0053] During use, the base 10 is fixed to the worktable, meaning that the base 10 is stationary. It can be understood that the base 10 can be a plate-like structure, a block-like structure, etc.
[0054] For example, please refer to Figure 4 The base 10 is provided with fixing holes 13, and the base 10 is fixed to the worktable through the fixing holes 13. There are multiple fixing holes 13.
[0055] It is understood that the card slots 40 can be arranged in two sets along the first direction X; or, the card slots 40 can be arranged in three sets along the first direction X; or, the card slots 40 can be arranged in four sets along the first direction X; or, the card slots 40 can be arranged in five or more sets along the first direction X. Each set of card slots 40 allows the positioning seat 20 to be held at a different angle.
[0056] The structure of the positioning seat 20 is not limited in this application, as long as it can be inserted into multiple sets of slots 40 to adjust the angle of the positioning seat 20.
[0057] The clamp 30 is disposed on the positioning seat 20. It can be understood that the clamp 30 can be fixed to the positioning seat 20 in a non-removable manner, for example, the clamp 30 can be welded to the positioning seat 20; or, the clamp 30 can be fixed to the positioning seat 20 in a detachable manner, for example, the clamp 30 can be fixed to the positioning seat 20 by threaded fasteners (such as screws, bolts, etc.).
[0058] The clamp 30 is used to clamp the product under test 200. It can be understood that the clamp 30 can clamp the product under test 200 using its own structure, for example, the clamp 30 is a flat-jaw pliers; or, the clamp 30 can also cooperate with the positioning seat 20 to clamp the product under test 200, for example, the clamp 30 is an elbow clamp.
[0059] The beneficial effects of the pose adjustment device 100 provided in this application embodiment are as follows: In use, the base 10 is first fixed on the worktable, and then the clamp 30 is used to clamp and fix the product to be tested 200 onto the positioning seat 20, so that the product to be tested 200, the clamp 30, and the positioning seat 20 form a whole; by inserting the positioning seat 20 into multiple sets of slots 40 respectively to adjust the angle of the positioning seat 20, the installation angle of the product to be tested 200 is simulated. Compared with the prior art, this pose adjustment device 100 does not require a drive mechanism, which solves the problem of the relatively complex structure of the existing pose adjustment device 100 and reduces production costs.
[0060] Please refer to Figure 1 In some embodiments, the base 10 includes a first seat body 11 and a second seat body 12 arranged at intervals along the second direction Y, and each set of slots 40 includes a first slot 41 provided on the first seat body 11 and a second slot 42 provided on the second seat body 12; wherein, the first direction X is perpendicular to the second direction Y.
[0061] The base 10 includes a first seat body 11 and a second seat body 12 arranged at intervals along the second direction Y. It can be understood that the base 10 is a split structure. The first seat body 11 and the second seat body 12 are respectively fixed on the worktable.
[0062] Each set of slots 40 includes a first slot 41 on the first base 11 and a second slot 42 on the second base 12. It can be understood that the two ends of the positioning seat 20 are respectively inserted into the first slot 41 and the second slot 42 so that the positioning seat 20 is held at a set angle.
[0063] It should be noted that the first direction X is perpendicular to the second direction Y, but this is not limited to a strict sense of perpendicularity; that is, the first direction X can also be approximately perpendicular to the second direction Y.
[0064] Based on the above technical solution, since the first base 11 and the second base 12 are arranged at intervals, the materials used to manufacture the base 10 can be reduced, thus lowering material costs; at the same time, the weight of the base 10 can also be reduced, which is beneficial for handling.
[0065] In other embodiments, the base 10 can be an integral structure, that is, the first base 11 and the second base 12 can be connected together by a connector, for example, the connector connects the bottom of the first base 11 and the second base 12 so that the base 10 as a whole has a U-shaped structure.
[0066] Please refer to Figure 1 and Figure 2 In some embodiments, in the second direction Y, the first end of the positioning seat 20 is provided with a flat plate 21, the second end of the positioning seat 20 is provided with a rectangular block 22, and the clamp 30 includes a clamping block 31, which cooperates with the rectangular block 22 to clamp the product to be tested 200.
[0067] The width of the plate 21 in the first direction X is W3, and the thickness of the plate 21 in the third direction Z is T.
[0068] Wherein, the length of the first side of the rectangular block 22 in the first direction X is L1, and the length of the second side of the rectangular block 22 in the third direction Z is L2, wherein the first side of the rectangular block 22 in the first direction X and the second side of the rectangular block 22 in the third direction Z are adjacent sides.
[0069] For example, the width W3 of the plate 21 in the first direction X is equal to the length L1 of the first side of the rectangular block 22 in the first direction X.
[0070] The rectangular block 22 and the clamping block 31 are arranged at intervals in the second direction Y.
[0071] When clamping the product under test 200, the product under test 200 is first placed between the clamping block 31 and the rectangular block 22. Then, the handle 32 of the clamping device 30 is moved so that the clamping block 31 moves closer to the rectangular block 22 along the second direction Y, thereby clamping and fixing the product under test 200 between the clamping block 31 and the rectangular block 22. When removing the product under test 200, the handle 32 is moved in the opposite direction so that the clamping block 31 moves away from the rectangular block 22 along the second direction Y, thereby releasing the clamping of the product under test 200. For example, the clamping device 30 is an elbow clamp.
[0072] For example, the clamping block 31 is provided with a flexible pad on the side facing the rectangular block 22 and / or the rectangular block 22 is provided with a flexible pad on the side facing the clamping block 31 to avoid pinching the product 200 under test.
[0073] Based on the above technical solution, since the rectangular block 22 is part of the positioning seat 20, the structure of the clamp 30 can be simplified by using the clamping block 31 in conjunction with the rectangular block 22 to clamp the product 200 to be tested.
[0074] In other embodiments, the clamp 30 includes a base and a first clamping block and a second clamping block disposed on the base. The first clamping block and the second clamping block are arranged at a distance along a second direction Y. One of the first clamping block and the second clamping block is a fixed block, and the other of the first clamping block and the second clamping block is a movable block. The product to be tested 200 is clamped and fixed between the fixed block and the movable block by moving the movable block along the second direction Y; the clamping of the product to be tested 200 is released by moving the movable block away from the fixed block along the second direction Y.
[0075] Please refer to Figure 3 and Figure 4 In some embodiments, one set of card slots 40 is a first set of card slots 40a, in which the first card slot 41 and the second card slot 42 in the first set of card slots 40a both extend along a third direction Z, wherein the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y.
[0076] In the first set of card slots 40a, both the first card slot 41 and the second card slot 42 extend along the third direction Z. This can be understood as, in Figure 3 In the first set of card slots 40a, the openings of the first card slot 41 and the second card slot 42 both face upwards.
[0077] Among them, the width of the first slot 41 in the first group of slots 40a in the first direction X is W1, and the width of the second slot 42 in the first group of slots 40a in the first direction X is W2.
[0078] For example, the width W1 of the first card slot 41 in the first group of card slots 40a in the first direction X is equal to the width W2 of the second card slot 42 in the first group of card slots 40a in the first direction X.
[0079] It should be noted that the third direction Z is perpendicular to the first direction X, but this is not limited to being perpendicular in the strict sense; that is, the third direction Z can also be approximately perpendicular to the first direction X. Similarly, the third direction Z is perpendicular to the second direction Y, but this is not limited to being perpendicular in the strict sense; that is, the third direction Z can also be approximately perpendicular to the second direction Y.
[0080] The width W1 of the first slot 41 in the first group of slots 40a in the first direction X is the same as the length L1 of the first side of the rectangular block 22; the width W2 of the second slot 42 in the first group of slots 40a in the first direction X is the same as the width W3 of the plate 21.
[0081] It should be noted that the width W1 of the first slot 41 in the first group of slots 40a in the first direction X is the same as the length L1 of the first side of the rectangular block 22. This is not strictly required; that is, the width W1 of the first slot 41 in the first group of slots 40a in the first direction X can also be slightly larger than the length L1 of the first side of the rectangular block 22, as long as it is within the tolerance range. Similarly, the width W1 of the second slot 42 in the first group of slots 40a in the first direction X is the same as the width W2 of the plate 21. This is not strictly required; that is, the width W1 of the second slot 42 in the first group of slots 40a in the first direction X can also be slightly larger than the width W2 of the plate 21, as long as it is within the tolerance range.
[0082] Based on the above technical solution, please refer to Figure 5 After the clamp 30 clamps and fixes the product under test 200, and the positioning seat 20 is inserted into the first set of slots 40a, the installation angle of the product under test 200 can be 0°.
[0083] Please refer to Figure 3 and Figure 4 In some embodiments, one set of card slots 40 is a second set of card slots 40b, in which the first card slot 41 and the second card slot 42 in the second set of card slots 40b both extend along a third direction Z, wherein the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y.
[0084] In the second set of card slots 40b, both the first card slot 41 and the second card slot 42 extend along the third direction Z. This can be understood as, in Figure 3 In the second set of card slots 40b, the openings of the first card slot 41 and the second card slot 42 both face upwards.
[0085] Among them, the width of the first slot 41 in the second group of slots 40b in the first direction X is W4, and the width of the second slot 42 in the second group of slots 40b in the first direction X is W5.
[0086] For example, the width W4 of the first slot 41 in the second set of slots 40b in the first direction X is greater than the width W5 of the second slot 42 in the second set of slots 40b in the first direction X.
[0087] It should be noted that the third direction Z is perpendicular to the first direction X, but this is not limited to being perpendicular in the strict sense; that is, the third direction Z can also be approximately perpendicular to the first direction X. Similarly, the third direction Z is perpendicular to the second direction Y, but this is not limited to being perpendicular in the strict sense; that is, the third direction Z can also be approximately perpendicular to the second direction Y.
[0088] The width W4 of the first slot 41 in the second set of slots 40b in the first direction X is the same as the length L2 of the second side of the rectangular block 22. The width W5 of the second slot 42 in the second set of slots 40b in the first direction X is the same as the thickness T of the plate 21. The first side and the second side of the rectangular block 22 are adjacent.
[0089] It should be noted that the width W4 of the first slot 41 in the second set of slots 40b in the first direction X is the same as the length L2 of the second side of the rectangular block 22. This is not strictly required; that is, the width W4 of the first slot 41 in the second set of slots 40b in the first direction X can also be slightly larger than the length L2 of the second side of the rectangular block 22, as long as it is within the tolerance range. Similarly, the width W5 of the second slot 42 in the second set of slots 40b in the first direction X is the same as the thickness T of the plate 21. This is not strictly required; that is, the width W5 of the second slot 42 in the second set of slots 40b in the first direction X can also be slightly larger than the thickness T of the plate 21, as long as it is within the tolerance range.
[0090] Based on the above technical solution, please refer to Figure 6 After the clamp 30 clamps and fixes the product under test 200, and the positioning seat 20 is inserted into the second set of slots 40b, the installation angle of the product under test 200 can be 90°.
[0091] Please refer to Figure 3 and Figure 4 In some embodiments, one set of card slots 40 is a third set of card slots 40c, and the first card slot 41 and the second card slot 42 in the third set of card slots 40c both extend along the third direction Z.
[0092] In the third set of card slots 40c, both the first card slot 41 and the second card slot 42 extend along the third direction Z. This can be understood as, in Figure 3 In the third set of card slots 40c, the openings of the first card slot 41 and the second card slot 42 both face upwards.
[0093] Among them, the width of the first slot 41 in the third group of slots 40c in the first direction X is W4, and the width of the second slot 42 in the third group of slots 40c in the first direction X is W6.
[0094] For example, the width W4 of the first card slot 41 in the third group of card slots 40c in the first direction X is greater than the width W6 of the second card slot 42 in the first direction X in the third group of card slots 40c; the width W6 of the second card slot 42 in the third group of card slots 40c in the first direction X is the same as the width W5 of the second card slot 42 in the second group of card slots 40b in the first direction X.
[0095] The first slot 41 in the third group of slots 40c is the same as the first slot 41 in the second group of slots 40b. The width W6 of the second slot 42 in the third group of slots 40c in the first direction X is the same as the thickness T of the plate 21.
[0096] The first slot 41 in the third group of slots 40c and the first slot 41 in the second group of slots 40b are the same slot. That is, the third group of slots 40c and the second group of slots 40b share the first slot 41. This design helps to reduce the size of the base 10 in the first direction X.
[0097] It should be noted that the width W6 of the second slot 42 in the third set of slots 40c in the first direction X is the same as the thickness T of the plate 21, but it is not limited to being the same in a strict sense. That is, the width W6 of the second slot 42 in the third set of slots 40c in the first direction X can also be slightly larger than the thickness T of the plate 21, as long as it is within the error range.
[0098] Based on the above technical solution, please refer to Figure 7 After the clamp 30 clamps and fixes the product under test 200, and the positioning seat 20 is inserted into the third set of slots 40c, the installation angle of the product under test 200 can be -90°.
[0099] In other embodiments, the third set of card slots 40c and the second set of card slots 40b may not share the first card slot 41, that is, the number of first card slots 41 on the first base 11 is the same as the number of second card slots 42 on the second base 12.
[0100] Please refer to Figure 3 and Figure 4 In some embodiments, one set of card slots 40 is a fourth set of card slots 40d, and the first card slot 41 and the second card slot 42 in the fourth set of card slots 40d are both inclined slots.
[0101] This can be understood as the openings of the first slot 41 and the second slot 42 in the third set of slots 40c both facing obliquely upwards. For example, the inclination angle of the oblique slot can be -30°, -45°, -60°, etc.
[0102] In the fourth set of card slots 40d, the width of the first card slot 41 in the direction perpendicular to its inclination is W7, and the width of the second card slot 42 in the fourth set of card slots 40d in the direction perpendicular to its inclination is W8. Moreover, the width W7 of the first card slot 41 in the fourth set of card slots 40d in the direction perpendicular to its inclination is greater than the width W8 of the second card slot 42 in the fourth set of card slots 40d in the direction perpendicular to its inclination.
[0103] For example, the width W7 of the first slot 41 in the fourth group of slots 40d in the direction perpendicular to its inclination is equal to the width W4 of the first slot 41 in the third group of slots 40c in the first direction X; the width W8 of the second slot 42 in the fourth group of slots 40d in the direction perpendicular to its inclination is equal to the width W6 of the second slot 42 in the third group of slots 40c in the first direction X.
[0104] The width W7 of the first slot 41 in the fourth set of slots 40d perpendicular to its inclined direction is the same as the length L1 of the second side of the rectangular block 22, and the width W8 of the second slot 42 in the fourth set of slots 40d perpendicular to its inclined direction is the same as the thickness T of the plate 21.
[0105] It should be noted that the width W7 of the first slot 41 in the fourth group of slots 40d in the direction perpendicular to its inclination is the same as the length L2 of the second side of the rectangular block 22. This is not strictly required; that is, the width W7 of the first slot 41 in the fourth group of slots 40d in the direction perpendicular to its inclination can also be slightly larger than the length L2 of the second side of the rectangular block 22, as long as it is within the tolerance range. Similarly, the width W8 of the second slot 42 in the fourth group of slots 40d in the direction perpendicular to its inclination is the same as the thickness T of the plate 21. This is not strictly required; that is, the width W8 of the second slot 42 in the fourth group of slots 40d in the direction perpendicular to its inclination can also be slightly larger than the thickness T of the plate 21, as long as it is within the tolerance range.
[0106] Based on the above technical solution, please refer to Figure 8 After the clamp 30 clamps and fixes the product under test 200, and the positioning seat 20 is inserted into the fourth set of slots 40d, the installation angle of the product under test 200 can be tilted.
[0107] In some embodiments, the width W3 of the plate 21 is more than 5 times the thickness T of the plate 21.
[0108] Specifically, Figure 9 A, B, and C in the equation satisfy the formula: Bsinθ + Acosθ = C;
[0109] The solution is:
[0110] A, B, and C are all guaranteed by machining. Generally speaking, A < C ≤ 1.01A, B ≥ 5A, from which we can calculate that θ ≤ 0.12°. That is, theoretically, the angle control accuracy of this posture adjustment device 100 is better than 0.12°.
[0111] Increasing the ratio of the width W3 of the plate 21 to the thickness T of the plate 21, and reducing the mating gap between the plate 21 and the second slot 42, can improve the angle control accuracy.
[0112] The posture adjustment device 100 provided in this application embodiment has the following advantages compared with the prior art: it has no excessive transmission mechanism, simple structure, high stability, and basically no risk of damage; it is simple and direct to operate, requires low operator skill, and is not prone to errors; it requires no lubrication and can be applied to high-cleanliness, high-vacuum and other application scenarios; the main components can be processed by conventional machining, resulting in low manufacturing cost; it has strong versatility, and the design dimensions can be flexibly changed according to different products 200 to be tested; it has high precision, with a precision control accuracy better than 0.5°, which can meet most conventional needs.
[0113] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
