Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of handle assembly, especially a general handle tool and an angle limiting sheet feeding device. BACKGROUND

[0002] In the door control system, the handle (also known as the handle) is a key operating component on the door panel, which directly serves the user's opening and closing needs. With the continuous development of the market, the design of the handle shows a trend of diversification, especially in the appearance design of the handle and the panel, which shows rich creativity. In terms of internal structure, core components such as the clasp spring, the angle limiting sheet, the torsion spring and the gasket have gradually formed an industry standard to ensure functionality and reliability.

[0003] As shown in Figure 1 and Figure 2 , the existing handle structure usually contains the following components: handle, shaft sleeve, inner cover or outer cover (or face cover), gasket, torsion spring, angle limiting sheet and clasp spring. These components work together to ensure the functionality and stability of the handle, in which:

[0004] Handle: The end part is designed with a 90° bent cylindrical shaft end, and a mandrel hole is provided in the middle of the shaft end, with a pair of limiting grooves formed on both sides of the mandrel hole along the radial direction.

[0005] Shaft end: The side away from the handle is provided with a limiting ring groove around the circumference, which is used to embed the clasp spring and stop and limit other parts through the outside of the clasp spring.

[0006] Inner cover or outer cover: The center is provided with a through hole matched with the shaft end with a gap, and a torsion spring limiting structure is provided at the bottom of one side of the through hole to fix the position of the torsion spring, and the inner side of the bottom of the inner cover or outer cover is concave to form an inner edge.

[0007] Torsion spring: The two ends form a hook end and a clamping end, respectively, the former cooperates with the torsion spring limiting structure on the inner cover or outer cover or face cover, and the latter is embedded in the limiting groove of the shaft end to realize angle limiting.

[0008] Angle limiting sheet: It is in the form of a ring sheet with a pair of stoppers extending outward along the circumference and a pair of limiting ends on the inner side of the ring surface. The stoppers are placed on both sides of the torsion spring limiting structure to limit the circumferential rotation of the clamping block, and the limiting ends cooperate with the limiting groove of the shaft end to further enhance the angle limiting effect.

[0009] Limiting hole: In order to facilitate the installation of the inner cover or outer cover or face cover and prevent it from being twisted, a hollow limiting hole or a protruding limiting shaft is usually provided on it to ensure accurate positioning during assembly.

[0010] At present, the tooling design of handle assembly equipment on the market is mostly fixed, aiming at assembling handles in a specific direction. For handles in different directions, manufacturers usually need to prepare two different toolings, the main difference of which lies in the handle, the corner limiting sheet, the torsional spring and the directionality of the inner cover or outer cover limiting hole. When switching to produce handles in different directions, not only the corresponding tooling needs to be replaced, but also the feeding device needs to be adjusted to adapt to the new assembly requirements, which is a complex and time-consuming process, increasing the cost and time of production.

[0011] The present scheme focuses on optimizing the feeding device of the corner limiting sheet and the matching handle tooling. Through optimized design, the device can flexibly adapt to the assembly requirements of handles in different directions without frequent replacement of tooling or additional adjustment of the feeding system.

[0063] The inner side of the clamping spring 17 is clamped into the limiting ring slot 114 to achieve stop limiting of other parts by the outer side.

[0067] In addition, in order to facilitate the positioning of the inner cover 13 or the outer cover and prevent the inner cover 13 or the outer cover from being twisted to facilitate assembly, the edge of the inner edge 134 of the inner cover 13 or the outer cover is usually also provided with a hollow limiting hole 133, or the edge of the inner edge 134 of the inner cover 13 or the outer cover is provided with a protruding limiting shaft (not shown in the figure). Embodiment

[0068] Please refer to Figures 1 to 3 , which is a universal handle tool as the best embodiment of the utility model, comprising a tool outer seat 20, a mandrel 30, a cover sleeve seat, a positioning hole 42, a positioning shaft 421, a limiting hole 43 and a limiting portion 431, wherein:

[0069] The tool outer seat 20 is a positioning base for combining the tool with other installation surfaces, and the form of the tool outer seat 20 can be composed of various shapes, such as a rectangular or circular or elliptical or a rectangular solid structure formed by stretching with a round corner and a right angle transition;

[0070] The mandrel 30 is in the form of a column as a whole, and is protruded at the center position of the upper end surface of the tool outer seat 20, the center position of the clamping spring 17, the corner limiting piece 16, the torsion spring 15 and the inner cover 13 or the outer cover is penetrated along the mandrel 30 to be nested and positioned on the mandrel 30, and a positioning column 31 which can be embedded with the core shaft hole 112 of the handle 11 end is protruded at the upper end middle part of the mandrel 30, and a group of limiting grooves 32 distributed in the vertical direction are symmetrically arranged on the two sides of the mandrel 30 along the radial direction thereof;

[0071] Thus, the two limiting grooves 32 radially symmetrically distributed along the mandrel 30 serve as the basis for limiting, the limiting ends 162 inside the corner limiting piece 16 are respectively inserted into one of the limiting grooves 32, forming the positioning of the corner limiting piece 16, according to the different directions of the handle 10, the stop portion 161 of the corner limiting piece 16 has different orientations on the mandrel 30, and the orientations are positioned by the limiting ends 162 inside the corner limiting piece 16 and the limiting grooves 32 at the corresponding positions.

[0072] The cover surface sleeve is coaxially arranged with the mandrel 30, and is used for positioning the inner edge 134 of the inner recess on the bottom side of the inner cover 13 or the outer cover;

[0073] In this embodiment, the cover surface sleeve (not marked in the figure) includes a disc-shaped base 40 and a plurality of positioning edges 41 upwardly protruding along the outer circumference of the upper end surface of the base 40, the plurality of positioning edges 41 are adapted to the side wall of the inner edge 134 of the inner recess on the bottom side of the inner cover 13 or the outer cover, or are limited in cooperation with the outer circumference of the inner cover or the outer cover, and in this embodiment, the positioning edges 41 are symmetrical and uniform with four.

[0074] In some embodiments, the base of the cover surface sleeve can also be shaped as a polygon, and the inner cover or the outer cover can also be limited, which is not limited to the shape of the base.

[0075] Thus, when the through hole 131 of the inner cover 13 or the outer cover is inserted into the mandrel 30, the inner edge 134 of the bottom of the inner cover 13 or the outer cover is nested on the four positioning edges 41, thereby completing the preliminary positioning of the inner cover 13 or the outer cover, and at this time, if there is no other limitation, the inner cover 13 or the outer cover can rotate circumferentially around the mandrel 30.

[0076] Therefore, in order to form the circumferential rotation limiting of the inner cover 13 or the outer cover and form the positioning of the inner cover 13 or the outer cover in different installation directions, the following specific scheme is made in this embodiment, which is for the case that the inner edge 134 of the bottom of the inner cover 13 or the outer cover is hollowed out as a limiting hole 133, and the specific scheme is as follows:

[0077] First, the positioning hole 42 is symmetrically arranged on the upper end of the cover surface sleeve along the radial direction of the cover surface sleeve, and the positioning shaft 421 is detachably arranged in the positioning hole 42;

[0078] Since the limiting hole 133 of the inner cover 13 or the outer cover is generally used as a structure for subsequent locking screws, its shape is usually circular, and the shape of the positioning hole 42 is also correspondingly set as circular, but it can also be modified as square or other shapes according to actual needs, which is not limited here.

[0079] The inner cover 13 or the outer cover of the handle 10 in different directions is different in that the position of the limiting hole 133 is radially symmetrical to the limiting hole 133 of the inner cover 13 or the outer cover of the handle 10 in another direction, so that the two positioning holes 42 radially symmetrically distributed can provide two different mounting points for the positioning shaft 421 to adapt to the assembly process of the handle 10 in different directions.

[0080] The side wall of the tool outer seat 20 is provided with a locking hole 21 penetrating the positioning hole 42, and the locking hole 21 and the corresponding locking bolt can lock and fix the positioning shaft 421 in the positioning hole 42, and the locking height can be adjusted to adapt to the assembly of the handle 10.

[0081] In addition, for the universal assembly of the angular limiting piece 16, the limiting holes 43 are radially symmetrically distributed on the upper end of the cover sleeve, and the limiting part 431 is detachably arranged in one of the limiting holes 43.

[0082] In the embodiment, the limiting part 431 is cylindrical, and the cross-sectional shape is square. The tool outer seat 20 is provided with another locking hole 21 penetrating the limiting hole 43, and the locking hole 21 and the corresponding locking bolt (not shown in the figure) can lock and fix the limiting part 431 in the limiting hole 43, and the locking height can be adjusted to adapt to the assembly of the handle 10.

[0083] When the handle 10 in different directions is assembled, the angular limiting block of the handle 10 is different in that the positions of the two stop parts 161 are radially symmetrical to the stop parts 161 of the angular limiting piece 16 corresponding to the handle 10 in another direction, so that the two limiting holes 43 radially symmetrically distributed can provide two different mounting points for the limiting part 431 to adapt to the assembly process of the handle 10 in different directions.

[0084] After the limiting part 431 is installed, the two stop parts 161 of the angular limiting piece 16 are located on both sides of the limiting part 431, and the position of the limiting part 431 corresponds to the torsional spring limiting structure 132 of the inner bottom of the inner cover 13 or the outer cover. When the angular limiting block is transferred to the handle 10, the two stop parts 161 are transferred to the inner cover 13 or the outer cover and the stop parts 161 are located on both sides of the torsional spring limiting structure 132, so as to realize the rotation range limitation of the angular limiting block.

[0085] Preferably, in order to accommodate the assembly process of each component of the handle 10, each type of telescopic mechanism is given a clearance to facilitate the placement of each component into the tooling. The cover sleeve is provided with a clearance area 44 along its radial direction, and the mandrel 30 is arranged at the center of the clearance area 44. For some types of handle 10, the clearance area 44 can also not be provided, and the clearance area can also not be arranged along the radial direction of the cover sleeve, but can be arranged as a circular groove similar to the outer circumference of the cover sleeve, and the like, which is not limited herein.

[0086] Preferably, the limiting portion 431 is columnar, and its cross-sectional shape is circular, square, waist-shaped, or triangular. The shape of the limiting hole 43 is adapted to the cross-sectional shape of the limiting portion 431, and the specific shape of the limiting portion 431 is selected according to the assembly needs of the handle 10 in different installation directions, which is not limited herein.

[0087] In this embodiment, the cross-sectional shape of the tooling outer seat 20 can be circular, square, or square with an excessive corner angle. In order to facilitate processing, the tooling outer seat 20 with a square cross-section with a corner angle is preferred, but it is not a specific limitation on the tooling outer seat 20. Embodiment

[0088] Please refer to Figure 4 , which is a universal handle tooling according to Embodiment Two of the present application, and differs from Embodiment One in that this embodiment is a specific scheme for the protruding type of limiting shaft of the inner cover 13 or the inner edge 134 of the bottom of the outer cover, which achieves the following:

[0089] The positioning shaft 421 is removed from the positioning hole 42, so that both positioning holes 42 are exposed. The size of the positioning hole 42 is designed to be just opposite to the size of the limiting shaft, so that no matter which direction the handle 10 is assembled, the protruding type of limiting shaft of the inner cover 13 or the bottom of the outer cover can be inserted into the corresponding positioning hole 42, and the circumferential rotation limiting of the inner cover 13 or the outer cover is completed. Embodiment

[0090] Please refer to Figures 5 to 8 , which is a corner limiting piece feeding device according to Embodiment Three of the present application, and is a universal handle 10 tooling according to Embodiment One, further comprising a feeding position 50, a transfer position 60, a pressing position 70, and the like:

[0091] The first telescopic clamping mechanism 80 includes a first telescopic mechanism 81 and a first clamping mechanism 82, and is used for clamping the corner limiting piece 16 of the feeding position 50.

[0092] The second telescopic clamping mechanism 90 includes a second telescopic mechanism 91 and a second clamping mechanism 92, and is used for clamping the corner limiting piece 16 of the transfer position 60.

[0093] The pressing mechanism 100 is used for pressing the corner limiting piece 16 of the pressing position 70 into the general tool of the handle 10;

[0094] The driving device 110 is used for controlling the first telescopic clamping mechanism 80 to move between the feeding position 50 and the transfer position 60 and controlling the second telescopic clamping mechanism 90 to move between the intermediate position and the general tool of the handle 10.

[0095] The first rotating assembly 120 is used for rotating in the vertical plane to correct the first orientation of the corner limiting piece 16 on the transfer position 60.

[0096] The second rotating assembly 130 is used for rotating in the horizontal plane to correct the second orientation of the corner limiting piece 16 on the second telescopic clamping mechanism 90.

[0097] Preferably, the first telescopic mechanism 81 and the second telescopic mechanism 91 are both linear cylinders with linear output, and the first clamping mechanism 82 and the second clamping mechanism 92 are both pneumatic finger cylinders.

[0098] The second rotating assembly 130 is a rotating cylinder or a motor or a gear combination, and in the embodiment, a rotating cylinder is selected, and other types of motors such as servo motors can be replaced according to needs, which are not limited here.

[0099] Preferably, the first rotating assembly 120 includes a first rotating mechanism 1201 and a third clamping mechanism 1202, the first rotating mechanism 1201 is a rotating cylinder or a motor or a gear combination, and the third clamping mechanism 1202 is a pneumatic finger cylinder and is arranged at the output end of the first rotating mechanism 1201.

[0100] In the embodiment, the first rotating mechanism 1201 is a rotating cylinder, and other types of motors such as servo motors can be replaced according to needs, which are not limited here.

[0101] In addition, in order to realize the 180° rotation of the corner limiting piece 16 in the vertical direction, the first rotating mechanism 1201 is fixed on the output end of the third telescopic mechanism 1203 which can be lifted, and in the embodiment, the third telescopic mechanism 1203 is a linear cylinder with linear output.

[0102] The pneumatic finger cylinder of the third clamping mechanism 1202 is fixed on the output end of the rotary cylinder and rotates with the output end. The pneumatic finger cylinder has two clamping jaws that can clamp towards each other. The inner side of the clamping jaws forms a clamping groove (not shown in the figure) for fixing the corner limiting piece 16. When the limiting end 162 on the corner limiting piece 16 in the transfer position 60 is oriented incorrectly, the pneumatic finger cylinder clamps the corner limiting piece 16 on both sides in the transfer position 60, and then pushes out through the output end of the third telescopic mechanism 1203, so that the rotary cylinder and the pneumatic finger cylinder drive the corner limiting piece 16 to rise. After the corner limiting piece 16 is separated from the transfer position 60, the rotary cylinder controls the corner limiting piece 16 to rotate 180° in the vertical plane, so that the limiting end 162 on the inner side of the corner limiting piece 16 restores to the normal orientation, thereby facilitating the subsequent press fitting of the corner limiting piece 16 to the mandrel 30 and making the limiting end 162 exactly clamped into the limiting groove 32 on both sides of the mandrel 30.

[0103] In the embodiment, the second turnover assembly 130 is a rotary cylinder, which is arranged on the output end of the second telescopic mechanism 91. The second clamping mechanism 92 is arranged on the output end of the second turnover assembly 130. The position of the second clamping mechanism 92 clamping the corner limiting block is exactly at the rotation center position of the output end of the second turnover assembly 130. Therefore, while the second telescopic mechanism 91 and the second clamping mechanism 92 normally clamp the corner limiting piece 16, the second turnover assembly 130 can make the corner limiting piece 16 rotate 180° in the horizontal plane, correct the orientation of the stop portion 161, and adapt to the assembly of the handle 10 in different directions.

[0104] Preferably, the driving device 110 includes a support 1101, a moving seat 1102, and a driving mechanism 1103. The moving seat 1102 is arranged to slide horizontally along the top of the support 1101. The driving mechanism 1103 is used to drive the moving seat 1102 to move linearly along the line connecting the loading position 50 and the press fitting position 70. The first telescopic clamping mechanism 80, the second telescopic clamping mechanism 90, and the press fitting mechanism 100 are respectively arranged on the moving seat 1102 and the distances between the first telescopic clamping mechanism 80, the second telescopic clamping mechanism 90, and the press fitting mechanism 100 are respectively adapted to the distances between the loading position 50, the transfer position 60, and the press fitting position 70.

[0105] In the embodiment, the driving mechanism 1103 is a linear cylinder. The moving seat 1102 is slidably installed on the top of the support 1101 in the horizontal direction through a guide rail sliding block structure 1104. The orientation is designed to be parallel to the line connecting the loading position 50 and the press fitting position 70, thereby facilitating the synchronous movement of the first telescopic clamping mechanism 80, the second telescopic clamping mechanism 90, and the press fitting mechanism 100 between the loading position 50, the transfer position 60, and the press fitting position 70. The orientation is set according to actual needs, which is not limited herein. In the embodiment, the output direction is oriented towards the loading position 50 as an example.

[0106] The intervals between the first telescopic clamping mechanism 80, the second telescopic clamping mechanism 90 and the pressing mechanism 100 are the same, and the intervals between the feeding position 50, the transfer position 60 and the pressing position 70 are equal to the intervals between the first telescopic clamping mechanism 80, the second telescopic clamping mechanism 90 and the pressing mechanism 100. When the driving mechanism 1103 is extended, the first telescopic clamping mechanism 80, the second telescopic clamping mechanism 90 and the pressing mechanism 100 are correspondingly moved to the feeding position 50, the transfer position 60 and the pressing position 70 respectively. After the first telescopic clamping mechanism 80, the second telescopic clamping mechanism 90 and the pressing mechanism 100 clamp the corner limiting piece 16 respectively and the corner limiting piece 16 on the pressing position 70 is pressed, the driving mechanism 1103 is retracted, the first telescopic clamping mechanism 80 and the second telescopic clamping mechanism 90 are correspondingly moved to the transfer position 60 and the pressing position 70 respectively, and the pressing mechanism 100 moves out of the range of the pressing position 70. Thus, the first telescopic clamping mechanism 80 can place the corner limiting piece 16 on the transfer position 60, and the second telescopic clamping mechanism 90 can move the corner limiting piece 16 to the pressing position 70. The above process is repeated to realize the order flow of the corner limiting piece 16 on the feeding position 50, the transfer position 60 and the pressing position 70. The orientation correction of the corner limiting piece 16 is realized by cooperating with the first turnover assembly 120 and the second turnover assembly 130, and the adaptive adjustment according to different handles 10 is facilitated.

[0107] Preferably, the intermediate position includes a clamping groove 61 adapted to the shape of the corner limiting piece 16, and the clamping groove 61 is provided with a position giving groove 62 for giving position to the first clamping mechanism 82, the second clamping mechanism 92 and the first turnover assembly 120.

[0108] In the embodiment, the position giving groove 62 includes left and right clamping grooves 621 and a turnover groove 622 close to the first turnover assembly 120, so as to give position to the clamping jaws of the pneumatic finger cylinder.

[0109] In the embodiment, the mandrel 30 is arranged at the center position of the position giving groove 62, and in some other embodiments, the mandrel 30 can also be arranged at other positions of the position giving groove 62, which is not limited to the arrangement position of the mandrel 30.

[0110] In the embodiment, the pressing mechanism 100 includes a fourth telescopic mechanism 101 and a pressing sleeve 102. The fourth telescopic mechanism 101 is a linear cylinder for linear telescopic extension. The pressing sleeve 102 is a hollow cylinder and is adapted to the shape of the mandrel 30. The pressing sleeve 102 is fixed to the output end of the fourth telescopic mechanism 101. When the corner limiting piece 16 is moved to the tooling of the pressing position 70, the fourth telescopic mechanism 101 is extended to press the corner limiting piece 16 into the bottom of the mandrel 30 through the pressing sleeve 102, thereby completing the assembly process of the corner limiting piece 16.

[0111] In the embodiment, the working processes of the first telescopic clamping mechanism 80 and the second telescopic clamping mechanism 90 are consistent, that is, the linear cylinder is extended to drive the pneumatic finger cylinder to move downward to the to-be-removed position of the corner limiting piece 16, and in the process, the clamping jaw of the pneumatic finger cylinder is opened and closed to complete the clamping and lifting of the corner limiting piece 16, and the driving device 110 is matched to realize the sequential circulation of the corner limiting piece 16 between the feeding position 50, the transfer position 60 and the press-fitting position 70.

[0112] In particular, in the embodiment, the feeding position 50 is used as the feeding position of the corner limiting piece 16, and the feeding mode can be various, such as automatic feeding through the connection of the vibration disc 52 by the straight vibration feeding mechanism 51, or semi-automatic feeding through the cooperation of the conveying belt by manual mode, which is not limited here.

[0113] One of the beneficial effects of the utility model is that the structure design of the tooling is improved, and the flexibility and efficiency of the handle 10 assembly are significantly improved.

[0114] Firstly, the positioning holes 42 are symmetrically arranged on the two radial sides of the tooling, which can adapt to the protruding limiting shaft of the inner cover 13 or the outer cover, and the positioning shaft 421 can be locked in one of the positioning holes 42 to flexibly adapt to the hollow limiting hole 133 of the inner cover 13 or the outer cover in the same direction.

[0115] Secondly, two limiting holes 43 are preset, and the limiting part 431 is installed in one of the limiting holes, which can accurately control the positions of the torsional spring 15 and the corner limiting piece 16, and then the tooling can be quickly adjusted to adapt to the handle 10 in different directions without replacing the entire tooling.

[0116] By switching the fixed positions of the positioning shaft 421 and the limiting part 431 or canceling them, the limiting process of the inner cover 13 or the outer cover and the corner limiting piece 16 in different directions can be adapted, so that the tooling can be quickly adjusted to adapt to the handle 10 in different installation directions without replacement.

[0117] The second beneficial effect of the utility model is that the transfer position 60 and the turnover assembly improve the universality of the feeding device, in particular:

[0118] Firstly, the transfer position 60 is introduced to temporarily store the corner limiting piece 16, so that the corner limiting piece 16 can be accurately corrected before entering the press-fitting position 70.

[0119] Secondly, when the initial orientation of the corner limiting piece 16 is incorrect, the first turnover assembly 120 can be rotated on the vertical plane to ensure that it is smoothly placed into the handle 10 tooling.

[0120] In particular, when the handle 10 of different directions is produced, the second turnover assembly 130 can be rotated to correct in the horizontal plane, ensuring that the orientation of the corner limiting piece 16 meets the new assembly requirements. Thereby, the line changing operation is greatly simplified, without additional adjustment of the equipment, and the assembly efficiency is significantly improved.

[0121] In summary, the utility model optimizes the tool structure and introduces the intermediate position 60 and the turnover assembly, solves the generality and the operation complex problem in the existing handle 10 assembly, significantly improves the generality of tool and the assembly efficiency of corner limiting piece 16 feeding device, makes the assembly of handle 10 more flexible, efficient and economic.

[0122] The utility model is described above in conjunction with the drawings, obviously, the specific implementation of the utility model is not limited by the above mode, as long as various non-essential improvements of the method concept and technical scheme of the utility model are adopted, or the concept and technical scheme of the utility model are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
