Description

Technical Field

[0001] The invention relates to the field of fastener assembly process methods, and in particular to a tool and method for quickly assembling a screw spring washer. Background Art

[0002] Since the assembly process often involves the use of screw fasteners for locking installation between components, and when using pan head or hex socket screws, for the reliability of installation, a combination of pan head / hex socket screws + spring washers + parallel washers is used for installation. The resulting problem is that the three fasteners need to be pre-assembled together. Although there are finished products of three-combination screws on the market, in some industrial fields, three-combination screws cannot be used directly, and the three fasteners still need to be pre-assembled together for use; at the same time, due to the different screw models, when pre-installing, when the smaller screws are combined with the spring washers, the center through hole of the spring washers is also smaller due to the smaller screw rod, which is time-consuming and labor-intensive to install manually, and it is not easy to align the installation, which greatly reduces the production efficiency.

[0003] In view of the above problems, there is an urgent need for a tool and method for quickly assembling screws, spring washers, and parallel washers. Summary of the invention

[0004] The object of the present invention is to provide a tool and method for quickly assembling screw spring washers, which can quickly assemble screws, spring washers and parallel washers and has a simple structure and is easy to operate.

[0005] In order to achieve the purpose of the present invention, the technical solution adopted is: a tooling for quickly assembling screw spring flat washers, comprising a base plate, a pad plate, a top column and a positioning plate, the positioning plate having legs, the positioning plate being mounted on the base plate through the legs, and the positioning plate also having positioning holes; the pad plate is placed on the base plate, the top column is vertically placed on the pad plate or the base plate, the upper end of the top column is inserted into the positioning hole, and the upper end surface of the top column is lower than the upper surface of the positioning plate; the upper end of the top column is also provided with a groove for accommodating a screw.

[0006] Furthermore, when the top column is placed on the pad, the distance between the upper end surface of the top column and the upper surface of the positioning plate is equal to the thickness of the parallel washer.

[0007] Furthermore, the thickness of the pad is equal to the thickness of the spring washer.

[0008] Furthermore, the size of the positioning hole matches the size of the parallel washer.

[0009] Furthermore, the positioning hole and the top column are clearance-matched.

[0010] Furthermore, the groove is in the shape of a circular hole, and the diameter of the groove is larger than the diameter of the screw and smaller than the size of the parallel washer.

[0011] Furthermore, the lower end of the top column is also provided with a limiting platform, and the size of the limiting platform is larger than the size of the top column.

[0012] Furthermore, there are multiple positioning holes, and the multiple positioning holes are evenly distributed on the positioning plate, and the number of top columns matches the number of positioning holes, and the upper ends of the multiple top columns are inserted into the multiple positioning holes one by one.

[0013] Furthermore, it also includes a tray, and the tray also has a receiving groove corresponding to the positioning hole.

[0014] Furthermore, the supporting legs are detachably connected to the base plate.

[0015] Furthermore, the supporting legs are connected to the base plate by bolts.

[0016] A method for quickly assembling a screw spring washer using the above-mentioned tooling comprises the following steps:

[0021] Furthermore, after the parallel washers, spring washers and screws are assembled, a tray is placed on the positioning plate, the tooling is turned over, and the overall structure assembled with the positioning plate, top column and bottom plate is removed.

[0022] The beneficial effects of the present invention are:

[0023] The present invention can not only quickly assemble screws, spring washers and parallel washers, but also has a simple structure and convenient operation, thereby greatly improving assembly efficiency.

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods. It is understood that the specific implementation methods described herein are only used to explain the relevant content, rather than to limit the present invention. It is also necessary to explain that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] like Figure 1 , Figure 2As shown, the present invention provides a tool for quickly assembling screw spring washers, comprising a base plate 1 and a positioning plate 6, wherein the positioning plate 6 is located above the base plate 1, and has legs 7 on the positioning plate 6, the legs 7 are connected to the base plate 1, so that the positioning plate 6 is supported on the base plate 1 through the legs 7, and there is a certain distance between the positioning plate 6 and the base plate 1; the positioning plate 6 is also provided with a positioning hole 8, and the positioning hole 8 vertically penetrates the positioning plate 6.

[0040] The tooling provided by the present invention also includes a pad 2, which is placed on the base plate 1 when needed and detached from the base plate 1 when not needed. Therefore, the pad 2 has no direct connection with the base plate 1 and only needs to be placed on the base plate 1 when in use.

[0041] The tooling provided by the present invention also includes a top column 3, which is arranged vertically. When the pad 2 is needed, the lower end of the top column 3 is placed on the pad 2, and when the pad 2 is not needed, the lower end of the top column 3 is placed on the bottom plate 1, that is, there is no connection between the top column 3 and the pad 2 and the bottom plate 1, and the lower end of the top column 3 is only placed on the pad 2 or the bottom plate 1; the upper end of the top column 3 is inserted into the positioning hole 8, and the upper end surface of the top column 3 is lower than the upper end surface of the positioning plate 6, that is, after the upper end of the top column 3 is inserted into the positioning hole 8, the lower end of the positioning hole 8 is blocked, and the upper end of the positioning hole 8 is still in an open state. At this time, the positioning hole 8 becomes a groove 5 structure, and the groove 5 structure is used to accommodate a spring washer or a parallel washer.

[0042] A groove 5 is also provided on the upper end surface of the top column 3 , and the screw rod on the screw is inserted into the groove 5 , and the center of the groove 5 is in the same straight line with the center of the top column 3 .

[0043] Since the fasteners are all prepared by first installing a spring washer on the screw and then installing a parallel washer, in the present invention, when the lower end of the top column 3 is placed on the pad 2, the distance between the upper end surface of the top column 3 and the upper surface of the positioning plate 6 is equal to the thickness of the parallel washer. For example, taking the installation of a spring washer and a parallel washer on a M1.6 pan head screw as an example, when the lower end of the top column 3 is placed on the pad 2, the distance between the upper end surface of the top column 3 and the upper surface of the positioning plate 6 is the thickness of the parallel washer of φ1.6.

[0044] Of course, if the fastener is a parallel washer firstly set on the screw and then the spring washer is set, when the lower end of the top column 3 is placed on the backing plate 2, the distance between the upper end surface of the top column 3 and the upper surface of the positioning plate 6 is equal to the thickness of the spring washer. That is, in the present invention, when the lower end of the top column 3 is placed on the backing plate 2, the distance between the upper end surface of the top column 3 and the upper surface of the positioning plate 6 is determined according to the washer that needs to enter the positioning hole 8 first.

[0045] In the present invention, since a spring washer needs to be placed into the positioning hole 8 after the parallel washer enters the positioning hole 8, when designing the pad 2, the thickness of the pad 2 is equal to the thickness of the spring washer, so that after the parallel washer enters the positioning hole 8, the pad 2 is pulled out. At this time, the distance between the upper surface of the parallel washer and the upper surface of the positioning plate 6 is the thickness of the spring washer. For example, taking the installation of a spring washer and a parallel washer on a M1.6 pan head screw as an example, the thickness of the pad 2 is the thickness of a φ1.6 spring washer.

[0046] In the present invention, in order to facilitate the extraction of the backing plate 2, as Figure 4 As shown, when designing the pad 2, the length of the pad 2 can be greater than the length of the base plate 1, or the length of the pad 2 can be greater than the width of the base plate 1, so that after the pad 2 is placed on the base plate 1, one end of the pad 2 extends outside the base plate 1, so that when the pad 2 is installed or extracted, the worker can directly hold the end of the pad 2 extending from the base plate 1 to pull it out or insert it. Of course, in the present invention, the length and width of the pad 2 can also be less than the length and width of the base plate 1. At this time, in order to facilitate the insertion or extraction of the pad 2, a raised handle can be provided on one side of the pad 2, so that the worker can pull out the pad 2 or insert the pad 2 into the base plate 1 by holding the handle.

[0047] Since the existing spring washers and parallel washers are both circular, the diameter of the spring washers mounted on the same type of screws is equal to the diameter of the parallel washers. Therefore, in the present invention, when designing the positioning hole 8, the shape of the positioning hole 8 is circular, and the diameter of the positioning hole 8 is slightly larger than the diameter of the spring washers, thereby ensuring that both the spring washers and the parallel washers can enter the positioning hole 8.

[0048] Of course, in the present invention, under the condition that the spring washer and the parallel washer can be installed in the positioning hole 8, the positioning hole 8 can also be a polygon, such as a regular pentagon, a regular hexagon, etc., but at this time, it is necessary to ensure that the diameter of the inscribed circle of the positioning hole 8 is slightly larger than the diameter of the spring washer. In addition, when the spring washer and the parallel washer to be sleeved on the screw are polygonal, the shape of the positioning hole 8 can be circular, and the shape of the positioning hole 8 can be consistent with the shape of the spring washer; specifically, when the shape of the positioning hole 8 is circular, and the spring washer and the parallel washer are polygonal, it is necessary to ensure that the diameter of the positioning hole 8 is slightly larger than the diameter of the circumscribed circle of the spring washer; when the shape of the positioning hole 8 is consistent with the shape of the spring washer and the parallel washer, the positioning hole 8 and the spring washer can be matched with each other.

[0049] In the present invention, the top column 3 is designed as follows: Figure 5As shown, the shape of the top column 3 is adapted to the shape of the positioning hole 8, and the top column 3 and the positioning hole 8 are clearance-matched, ensuring that the upper end of the top column 3 can be inserted into the positioning hole 8, so that the top column 3 can slide in the positioning hole 8. In addition, when the groove 5 on the top column 3 is designed, the center of the groove 5 is in the same straight line with the center of the top column 3, and the diameter of the groove 5 is slightly larger than the diameter of the screw on the screw, so as to ensure that the screw on the screw can be inserted into the groove 5 after passing through the spring washer and the parallel washer.

[0050] In the present invention, the groove 5 can be a circular hole. At the same time, in order to prevent the parallel washer and the spring washer from falling into the groove 5, the diameter of the groove 5 needs to be smaller than the diameter of the parallel washer. Of course, since the groove 5 is used to accommodate the screw rod on the screw, the groove 5 can also be other shapes, such as a regular pentagon, a regular hexagon, etc., while ensuring that the screw rod on the screw can be inserted into the groove 5. However, when the groove 5 is a polygon, the diameter of the inscribed circle of the groove 5 is slightly larger than the screw rod diameter of the screw.

[0051] In the present invention, in order to prevent the top column 3 from falling out of the positioning hole 8, the top column 3 is further provided with a stopper 4 at one end away from the positioning hole 8, and the diameter of the stopper 4 is larger than the diameter of the positioning hole 8, so that the top column 3 and the stopper 4 form a stepped shaft together. In addition, under the condition of ensuring that the top column 3 does not fall out of the positioning hole 8, the shape of the stopper 4 can be circular or polygonal, and the specific shape of the stopper 4 can be selected according to actual conditions.

[0052] In the present invention, in order to batch assemble fasteners, such as Figure 6 As shown, there are multiple positioning holes 8 on the positioning plate 6, and there are also multiple top pillars 3, and the multiple top pillars 3 correspond to the multiple positioning holes 8 one by one; in order to open as many positioning holes 8 as possible on the positioning plate 6, the multiple positioning holes 8 are arranged in a rectangular array on the positioning plate 6, and the spacing between two adjacent positioning holes 8 is equal. Of course, when the space occupied by the multiple positioning holes 8 on the positioning plate 6 is not considered, the multiple positioning holes 8 can be arranged at will on the positioning plate 6.

[0053] In the present invention, since the fasteners including the spring washers, parallel washers and screws are located in the positioning holes 8 after being assembled, in order to facilitate the removal of the assembled fasteners from the positioning holes 8, a tray 9 can be further provided on the positioning plate 6 after the fasteners are assembled. When the assembled fasteners need to be removed from the positioning holes 8, the entire tooling is turned over and the assembled fasteners are placed on the tray 9. At this time, the positioning plate 6, the base plate 1 and the top column 3 can be removed as a whole.

[0054] In order to prevent the fasteners from tipping over after being placed on the tray 9, Figure 2As shown, a receiving groove 10 corresponding to the positioning hole 8 is provided on the surface of the tray 9 opposite to the positioning plate 6, so that the assembled fasteners can directly enter the receiving groove 10 on the tray 9 when the entire tooling is turned over, thereby preventing the assembled fasteners from tilting on the tray 9 or directly rolling out of the tray 9.

[0055] In the present invention, when fasteners of different sizes need to be assembled, the positioning plate 6 having the positioning hole 8 of the corresponding size and the support leg 7 of the corresponding height can be directly replaced. Therefore, in order to facilitate the replacement of the positioning plate 6, the support leg 7 and the bottom plate 1 are preferably connected in a detachable manner. Specifically, Figure 3 , Figure 6 As shown, corresponding bolt holes can be opened on the base plate 1 and the legs 7, and bolts can be installed in the corresponding bolt holes on the base plate 1 and the legs 7, so as to achieve fixation between the base plate 1 and the legs 7. When the positioning plate 6 needs to be replaced, the bolts can be directly removed for replacement, making the replacement of the positioning plate 6 more convenient.

[0056] In the present invention, the legs 7 and the positioning plate 6 are an integrated structure. To facilitate the turning over of the tooling, the height of the legs 7 does not need to be too high, for example, 10 cm to 30 cm. To ensure the stability of the positioning plate 6, there are at least two legs 7. At the same time, to facilitate the pad 2 to raise all the top columns 3, the legs 7 are located at the edge of the positioning plate 6, and multiple legs 7 are symmetrically arranged on the positioning plate 6. In order to prevent the legs 7 from hindering the insertion and extraction of the pad 2, the distance between the legs 7 on both sides of the positioning plate 6 is less than the width of the positioning plate 6 or the length of the positioning plate 6.

[0057] In the present invention, in order to ensure that the receiving groove 10 on the tray 9 can accurately correspond to the positioning hole 8 on the positioning plate 6 after the tray 9 is covered on the positioning plate 6, a positioning groove can be opened on the upper surface of the positioning plate 6, and a positioning pin corresponding to the positioning groove can be set on the tray 9, so that the tray 9 can be quickly positioned through the cooperation of the positioning groove and the positioning pin when placed.

[0058] The method for quickly assembling the screw spring flat washer by using the above-mentioned tooling comprises the following steps after the positioning plate 6, the pad 2, the bottom plate 1 and the top column 3 are assembled:

[0059] S1. Lay the parallel washers to be installed flat on the positioning plate 6, and sweep the parallel washers to make them fall accurately into each positioning hole 8. Since the distance between the upper end surface of the top column 3 and the upper surface of the positioning plate 6 is the thickness of a parallel washer, each positioning hole 8 can only accommodate one parallel washer. Figure 7 As shown;

[0060] S2, pull the pad 2 out from between the top column 3 and the bottom plate 1, the top column 3 automatically falls on the bottom plate 1 according to its own gravity, and the parallel washer in the positioning hole 8 moves downward synchronously with the movement of the top column 3, so that the distance between the upper surface of the parallel washer and the upper surface of the positioning plate 6 is the thickness of a spring washer;

[0061] S3. Lay the spring washer to be installed flat on the positioning plate 6 and sweep the spring washer so that it falls accurately into each positioning hole 8. Since the distance between the upper surface of the parallel washer and the upper surface of the positioning plate 6 is the thickness of a spring washer, each positioning hole 8 can only accommodate one spring washer. Figure 8 As shown;

[0062] S4. Insert the screw into the parallel washer and the spring washer to complete the assembly of the screw, parallel washer and spring washer. Fig. 9 shown.

[0063] When the parallel washers, spring washers and screws are assembled, a tray 9 is placed on the positioning plate 6, and the tooling is turned 180 degrees. The assembled parallel washers, spring washers and screws automatically fall into the receiving groove 10 on the tray 9 by their own gravity. Fig.10 As shown, at this time, the staff can directly take out the assembled fasteners for use.

[0064] When the fastener is a screw that is first sleeved with a parallel washer and then sleeved with a spring washer, the above steps S1 and S3 can be swapped.

[0065] It should be understood by those skilled in the art that the above embodiments are only for the purpose of clearly illustrating the present invention, and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present invention.
