Description

Technical Field

[0001] The present invention belongs to the technical field of machine tools, and specifically relates to a machine for tightening screws, and more particularly to a screw machine, a supporting device and a use method. Background Art

[0002] During the production process, screws need to be screwed into the corresponding positions of the workpieces. The related technology adopts a clamping method for fastening the workpieces. The workpiece is placed on a plane. Since the workpiece is special-shaped, the bottom ends of some screw holes on the workpiece are in contact with the plane supporting the workpiece, but the bottom ends of some screw holes are empty, and the thickness of the workpiece at the positions of the empty screw holes on the workpiece is thinner. The pressure of the screw machine for screwing in the screws is certain and cannot be modified. When the screw machine screws the screw into the screw hole without a vacant bottom, the screwing pressure is adapted. However, if the screw machine screws the screw into the screw hole with a vacant bottom, due to the thinness of the workpiece at that position, the screwing pressure of the screw machine will cause the workpiece at that position to be pressed down, causing the workpiece to be damaged by pressure.

[0003] Therefore, due to the technical problem that when the screw is screwed into the empty screw hole at the bottom, the corresponding position on the workpiece will be pressed down, resulting in the workpiece being damaged by pressure, it is necessary to design a screw machine, a supporting device and a method of use.

[0004] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0068] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration."

On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0071] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0072] like Figure 2As shown, at least one disclosed embodiment provides a screw machine, comprising: a support device 1, wherein the support device 1 is suitable for supporting a workpiece 4; wherein the support device 1 comprises: a base plate 11 and a plurality of support mechanisms 16; wherein the support mechanisms 16 are arranged on the top surface of the base plate 11; the support mechanisms 16 correspond to the screw holes on the workpiece 4, the support mechanisms 16 are suitable for being inserted into the corresponding screw holes, and the support mechanisms 16 are suitable for supporting the bottom position of the screw holes on the workpiece 4 from the bottom surface of the workpiece 4, thereby achieving support for the bottom position of the screw holes from the bottom of the workpiece 4 during the process of screwing the screws into the workpiece 4, thereby avoiding the screw holes from being screwed in. During the screwing process, the screw hole is in an empty state, which causes the workpiece 4 to be pressed down and cause damage to the workpiece 4. Reducing the damage to the workpiece 4 will improve the yield rate of the workpiece 4; a partial thread is set in the screw hole, and no thread is set near the bottom of the screw hole; when the pressure of the screw machine to screw in the screw cannot be adjusted, the bottom of the empty screw hole is supported, so that the screw hole opened at a thinner position on the workpiece 4 is in a supported state. When the screw machine uses the same force to screw the screw into the screw hole that was originally in an empty state, the bottom of the originally empty screw hole can be supported by the supporting mechanism to avoid damage to the workpiece caused by downward pressure at this position of the workpiece 4.

[0073] There will be many screw holes on the special-shaped workpiece 4, among which the bottom ends of some screw holes are located on the plane and supported by the plane, and some screw holes are in a suspended state. The thickness of the workpiece 4 corresponding to these screw holes will also be thinner, resulting in these screw holes being suspended, and the force of the screw machine to screw in the screw cannot be adjusted. When the screw machine uses the same force to screw the screw into the suspended screw hole opened in the thinner position of the workpiece 4, it will cause the workpiece 4 to be pressed down. Since the workpiece 4 at this position is originally thinner, pressing down the workpiece 4 will cause damage to the workpiece. Therefore, in this embodiment, a supporting mechanism 16 is used to support the bottom of the screw hole in the suspended state to avoid pressing down on the workpiece 4 when the force of the screw machine to screw in the screw cannot be adjusted, thereby avoiding damage to the workpiece 4.

[0074] like Figure 2 and Figure 3As shown, in an optional embodiment, the support mechanism 16 includes: a sleeve 12 and a lifting cylinder 13; the bottom surface of the sleeve 12 is sealed, and the sleeve 12 is arranged on the top surface of the bottom plate 11; the lifting cylinder 13 is inserted into the sleeve 12, and a spring 17 is connected between the bottom surface of the lifting cylinder 13 and the inner bottom surface of the sleeve 12; a strip-shaped through groove 121 is vertically opened on the side wall of the sleeve 12; a lifting ring 131 is arranged outside the sleeve 12, and the lifting ring 13 The connecting block 132 arranged on the inner wall passes through the strip-shaped through groove 121 and is connected to the outer wall of the lifting cylinder 13. The strip-shaped through groove 121 can facilitate the connecting block 132 to move up and down. By contacting and pressing down the lifting ring 131, the lifting cylinder 13 can be driven to move downward. The inner wall of the lifting ring 131 contacts the outer wall of the sleeve 12. The lifting ring 131 can be used to receive and collect excess glue. The inner wall of the lifting ring 131 contacts the outer wall of the sleeve 12 to prevent the collected glue from flowing downward along the outer wall of the sleeve 12. Figure 3 The middle lifting ring 131 has been moved downward.

[0075] When the workpiece 4 is placed on the base plate 11, the workpiece 4 can also be placed on the platform on the base plate 11, etc. The sleeve 12 and the lifting cylinder 13 are inserted into the screw hole, so that the workpiece 4 can contact the lifting ring 131 to make the lifting cylinder 13 descend. At this time, the lifting ring 131 applies an upward force to the workpiece 4 through the compressed spring 17 to support the workpiece 4, and the sleeve 12 is extended into the screw hole and contacts the lowest point of the thread in the screw hole to limit the workpiece 4; the spring 17 can be used to support and reset the lifting cylinder 13; in the initial state, the top surface of the lifting cylinder 13 is higher than the top surface of the sleeve 12. At this time, the workpiece 4 is transported and placed on the base plate 11, and the workpiece 4 is moved from top to bottom. The workpiece 4 is placed on the bottom plate 11, and the top of the lifting cylinder 13 will extend into the screw hole from the bottom of the screw hole, and then the bottom surface of the workpiece 4 will contact the lifting ring 131 (contact the ring body 134 on the lifting ring 131). As the workpiece 4 moves downward, the lifting ring 131 will move downward, and then the lifting cylinder 13 will move downward. At this time, the top of the sleeve 12 will extend into the screw hole from the bottom of the screw hole, and the top of the sleeve 12 will contact the bottom of the thread opened in the screw hole. The position of the workpiece 4 is limited by the contact between the sleeve 12 and the bottom of the thread. At this time, the spring 17 is in a compressed state, and the workpiece 4 is supported from the bottom of the workpiece 4 by the elastic force of the spring 17 returning to the original position, and the conveying mechanism 2 keeps pressing the workpiece 4 downward.

[0076] In an optional embodiment, a sponge layer is provided on the outer wall of the lifting cylinder 13, and the distance between the outer wall of the sponge layer and the axis of the lifting cylinder 13 is greater than the outer diameter of the sleeve 12, so that when the lifting cylinder 13 is inserted into the screw hole, the sponge layer can contact the inner wall of the screw hole; glue is stored in the sleeve 12, and the sponge layer is suitable for absorbing the glue; the bottom surface of the connecting block 132 is provided with an insert block 133, and the width of the insert block 133 is adapted to the strip through groove 121; a slot 122 adapted to the insert block 133 is provided on the inner bottom surface of the strip through groove 121, and the insert block 133 is inserted into the slot 122; during the lifting process of the lifting cylinder 13, the insert block 133 is always inserted into the slot 122, and the part of the insert block 133 extending out of the slot 122 contacts the inner wall of the strip through groove 121, so as to prevent the glue in the sleeve 12 from flowing out of the strip through groove 121.

[0077] When the workpiece 4 is placed on the base plate 11, the lifting cylinder 13 is first inserted into the screw hole, and the glue is applied to the inner wall of the screw hole through the sponge layer; the glue stored in the sleeve 12 is a glue with good fluidity, which is easily absorbed by the sponge layer; when the lifting cylinder 13 is inserted into the screw hole, since the distance between the outer wall of the sponge layer and the axis of the lifting cylinder 13 is greater than the outer diameter of the sleeve 12, the sponge layer will contact the inner wall of the screw hole, and the inner wall of the screw hole will squeeze the sponge layer, so that the glue absorbed in the sponge layer is coated on the inner wall of the screw hole, and after the screw is screwed in later, the screw is better connected to the screw hole through the glue; a cross-shaped frame 135 can be provided inside the lifting cylinder 13, and the horizontal and vertical sides of the cross-shaped frame 135 are They are all arranged along the inner diameter of the lifting cylinder 13. When the screw is screwed into the screw hole, the debris generated by the contact and friction between the screw and the inner wall of the screw hole will fall into the sleeve 12. The cross-shaped frame 135 moves up and down with the lifting cylinder 13. The cross-shaped frame 135 moves up and down in the glue, and the cross-shaped frame 135 can rise above the glue liquid surface. The cross-shaped frame 135 can mix the debris that falls into the glue in the sleeve 12 with the glue to increase the adhesion performance of the glue; glue is applied on the inner wall of the screw hole. When the screw is screwed into the screw hole, a strong plastic film can be formed in the thread gap after the glue is cured, so that the screw is locked and will not loosen, and the metal screw can be prevented from loosening or going offline under the action of impact and vibration.

[0078] In an optional embodiment, a ring body 134 is provided on the top surface of the lifting ring 131, and the ring body 134 is arranged circumferentially along the lifting ring 131, and the ring body 134 is close to the edge of the lifting ring 131; a plurality of through holes 123 are opened on the sleeve 12, and the through holes 123 are arranged close to the top of the sleeve 12; the glue that flows out of the sleeve 12 when the sponge layer is squeezed will be received by the ring body 134, and after the lifting cylinder 13 moves upward, the received and collected glue will flow back into the sleeve 12 through the through holes 123, so as to facilitate the use of glue and avoid waste of glue; during the descent of the lifting cylinder 13, the sponge layer is squeezed by the sleeve 12, so that the glue in the sponge layer is squeezed out, and the sponge layer reabsorbs the glue after descending into the sleeve 12.

[0079] like Figure 4 and Figure 5 As shown, in an optional embodiment, at least one first clamping block 141 and at least one second clamping block 142 are provided on the top surface of the base plate 11, and the first clamping block 141 is suitable for sliding on the base plate 11; the first clamping block 141 is connected to the first cylinder 14, and the first cylinder 14 is suitable for driving the first clamping block 141 to move so that the first clamping block 141 is close to or away from the second clamping block 142; the workpiece 4 is placed between the first clamping block 141 and the second clamping block 142, and the first cylinder 14 drives the first clamping block 141 to move close to or away from the second clamping block 142. The second clamping block 142 is used to clamp the workpiece 4; when the workpiece 4 is placed on the base plate 11, the first clamping block 141 is moved toward the second clamping block 142 by the first cylinder 14, and the workpiece 4 is clamped by the first clamping block 141 and the second clamping block 142. The workpiece 4 is first placed on the base plate 11 from top to bottom, and an upward force is applied to the workpiece 4 by the lifting ring 131. At this time, the workpiece 4 is clamped by the first clamping block 141 and the second clamping block 142, so that the workpiece 4 is fixed on the base plate 11, and the workpiece 4 is prevented from being damaged by pressure when the screws are subsequently screwed into the screw holes.

[0080] In an optional embodiment, a limit block 151 is slidably provided on the top surface of the base plate 11, and the limit block 151 is connected to the second cylinder 15; the limit block 151 is arranged on one side of the first clamping block 141; the second cylinder 15 is suitable for driving the limit block 151 to move, and after the first cylinder 14 drives the first clamping block 141 to move, the first clamping block 141 contacts with the limit block 151; the position of the limit block 151 is adjusted by the second cylinder 15 to adjust the distance between the first clamping block 141 and the second clamping block 142 when the first clamping block 141 contacts the limit block 151, so as to adapt to workpieces 4 of different sizes, and the first clamping block 141 is limited by the contact between the limit block 151 and the first clamping block 141 to prevent the first clamping block 141 from being over-clamped and damaging the workpiece 4 during the movement toward the second clamping block 142.

[0081] In the initial state, the distance between the first clamping block 141 and the second clamping block 142 is greater than the width of the workpiece 4, and the top of the lifting cylinder 13 is higher than the top of the sleeve 12. At this time, the workpiece 4 is transported to the top of the base plate 11 by the transport mechanism 2, and then the workpiece 4 is placed on the base plate 11 from top to bottom by the transport mechanism 2. At this time, the top of the lifting cylinder 13 extends into the screw hole from the bottom of the screw hole, and the sponge layer on the lifting cylinder 13 applies glue to the screw hole. The top of the sleeve 12 extends into the screw hole from the bottom of the screw hole. The top of the sleeve 12 will contact the bottom of the thread opened in the screw hole, and the position of the workpiece 4 is limited by the contact between the sleeve 12 and the bottom of the thread. At this time, the spring 17 is in a compressed state, and the workpiece 4 is supported from the bottom of the workpiece 4 by the elastic force of the spring 17 returning to the original position. At this time, the workpiece 4 is kept The holding and conveying mechanism 2 presses down the workpiece 4, and the first cylinder 14 drives the first clamping block 141 to move toward the second clamping block 142, so that the first clamping block 141 and the second clamping block 142 clamp the workpiece 4, and by clamping the workpiece 4 and supporting the bottom of all screw holes of the workpiece 4, it is avoided that the workpiece 4 is crushed during the process of screwing in the screws. After clamping the workpiece 4, the conveying mechanism 2 leaves, and the screw driving mechanism 3 screws the screw into the screw hole. After the screw is screwed in, the first cylinder 14 drives the first clamping block 141 away from the second clamping block 142. At this time, the workpiece 4 is no longer clamped, and the spring 17 resets to make the lifting ring 131 move upward, driving the workpiece 4 to move upward, thereby making the workpiece 4 higher than the first clamping block 141 and the second clamping block 142, so as to facilitate moving the workpiece 4 out of the base plate 11.
