Description

Technical Field

[0001] The utility model relates to the field of casing press-in tooling, in particular to a casing press-in tooling. Background Art

[0002] For some existing workpieces, it is necessary to press-fit a flange sleeve into the reserved through-hole of the workpiece during production. For small-batch production, an existing low-cost solution is to use a sleeve pressing tool in conjunction with a simple pneumatic punch to press the flange sleeve into the reserved through-hole of the workpiece. The sleeve pressing tool includes a base and a pressing head. The base is convexly provided with a pipe hole positioning column. During production, the workpiece is placed on the base, and the pipe hole positioning column is inserted into the reserved through-hole. Then, one end of the flange sleeve is pre-inserted into the reserved through-hole of the workpiece. At this time, the pipe hole positioning column is inserted into one end of the inner hole of the flange sleeve, so that the flange sleeve can be guided when pressing it in. Currently, there may be dimensional errors between the flange sleeve and the workpiece during production. Therefore, when the pressing head presses the flange sleeve into the reserved through-hole of the workpiece, the end of the flange sleeve close to the base may collide with the base and deform, which may affect the normal installation and use of the flange sleeve, and damage the sleeve pressing tool. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a sleeve pressing tool.

[0005] The sleeve pressing tooling according to the embodiment of the present invention has at least the following beneficial effects: when the workpiece is placed on the workpiece supporting surface of the base, and the sleeve pressing surface of the pressing head presses the flange sleeve into the reserved through hole of the workpiece, the pipe hole positioning column can guide the inner hole of the flange sleeve so that the flange sleeve is inserted into the reserved through hole of the workpiece according to a preset direction. At this time, if the size error between the workpiece and the flange sleeve causes the end of the flange sleeve close to the base to extend out of the workpiece, then one end of the flange sleeve will press the elastic buffer ring, and the elastic buffer ring will undergo elastic deformation, so that one end of the flange sleeve will not have a hard collision with the base, and the main body of the base maintains stable support for the workpiece, thereby reducing the risk of collision and deformation of the flange sleeve and the base, and is not easy to damage the sleeve pressing tooling.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 3 , is a sleeve pressing tool according to an embodiment of the present invention, comprising a base 100, a pipe hole positioning column 200, and a pressing head 300. The base 100 is provided with a workpiece supporting surface 101; the pipe hole positioning column 200 is provided on the base 100 and is located on the workpiece supporting surface 101; the pressing head 300 is opposite to the workpiece supporting surface 101 and can move toward or away from the base 100, and a sleeve pressing surface 301 is provided on the side of the pressing head 300 close to the base 100; wherein the base 100 comprises a main body 110 and an elastic buffer ring 120, one end of the pipe hole positioning column 200 is connected to the main body 110, the elastic buffer ring 120 is provided on the main body 110 and sleeved on the outer circumference of the pipe hole positioning column 200, and one side of the elastic buffer ring 120 and one side of the main body 110 form the workpiece supporting surface 101.

[0032] The workpiece 610 is placed on the workpiece supporting surface 101 of the base 100. During the process of the sleeve pressing surface 301 of the pressing head 300 pressing the flange sleeve 620 into the reserved through hole of the workpiece 610, the pipe hole positioning column 200 can guide the inner hole of the flange sleeve 620 so that the flange sleeve 620 is inserted into the reserved through hole of the workpiece 610 according to a preset direction. At this time, if the size error between the workpiece 610 and the flange sleeve 620 causes the end of the flange sleeve 620 close to the base 100 to extend out of the workpiece 610, at this time, one end of the flange sleeve 620 will press the elastic buffer ring 120, and the elastic buffer ring 120 will undergo elastic deformation, so that one end of the flange sleeve 620 will not have a hard collision with the base 100, and the main body 110 of the base 100 maintains stable support for the workpiece 610, thereby reducing the risk of collision and deformation of the flange sleeve 620 and the base 100, and not easily damaging the sleeve pressing tooling. It is understandable that when the workpiece 610 and the flange sleeve 620 are removed from the base 100 , the elastic buffer ring 120 will return to its original state.

[0033] Specifically, when the elastic buffer ring 120 is deformed by the pressure of the flange sleeve 620, there is still enough space for the flange sleeve 620 to be installed in place relative to the workpiece 610. Furthermore, when the elastic buffer ring 120 is not deformed, it can also provide some support for the workpiece 610 and the flange sleeve 620, facilitating the assembly of the workpiece 610 and the flange sleeve 620 with relatively small dimensional errors.

[0034] Specifically, the pressing head 300 can be installed on a pneumatic punching machine when in use, so that the pressing head 300 is close to or away from the base 100 .

[0035] In this embodiment, the main body 110 is provided with a mounting groove 111. One end of the pipe hole locating column 200 is connected to the bottom of the mounting groove 111. The outer periphery of the pipe hole locating column 200 is spaced apart from the sidewall of the mounting groove 111. The elastic buffer ring 120 is embedded in the mounting groove 111. By embedding the elastic buffer ring 120 between the sidewall of the mounting groove 111 and the outer periphery of the pipe hole locating column 200, the installation position of the elastic buffer ring 120 is relatively secure and not prone to loosening. In addition, the elastic buffer ring 120 also provides a good buffering effect.

[0036] It is conceivable that in other embodiments, the elastic buffer ring 120 can also be sleeved on the outer periphery of the pipe hole positioning column 200 and directly placed on the side surface of the main body 110 of the base 100. Those skilled in the art can make specific configurations according to actual needs.

[0037] Specifically, the elastic buffer ring 120 is an annular member made of elastic material. For example, the elastic buffer ring 120 is a rubber ring, a silicone ring, etc., or the elastic buffer ring 120 can also be other structures, such as a shorter tube spring.

[0038] Specifically, the elastic buffer ring 120 and the main body 110 of the base 100 can be produced separately and then assembled together, or glue can be poured into the installation groove 111 of the main body 110, and the elastic buffer ring 120 can be directly formed through the groove wall of the installation groove 111 and the outer peripheral wall of the pipe hole positioning column 200.

[0039] It can be understood that the diameter of the elastic buffer ring 120 should be slightly larger than the diameter of the end of the flange sleeve 620 near the bottom, so as to allow the flange sleeve 620 to press the elastic buffer ring 120 to deform and embed it to a certain extent in the mounting groove 111, so as to avoid a hard collision between the main body 110 of the base 100 and the flange sleeve 620.

[0040] In an embodiment, one side of the elastic buffer ring 120 is flush with one side of the main body 110 , so as to facilitate adaptation to a workpiece 610 with a flat surface.

[0041] Specifically, the pipe hole positioning column 200 is a cylinder, and its diameter is slightly smaller than the inner hole of the flange sleeve 620 .

[0042] In the embodiment, a tube hole alignment boss 400 is further included. The tube hole alignment boss 400 is provided on the pressing head 300 and is located on the sleeve top pressing surface 301 . The tube hole alignment boss 400 is opposite to the tube hole positioning column 200 . When the flange sleeve 620 is pre-inserted into the reserved through hole of the workpiece 610, the flange sleeve 620 may be skewed at a small angle relative to the reserved through hole. At this time, the pressing head 300 presses the flange sleeve 620 into the reserved through hole, and the flange sleeve 620 may be skewed further relative to the workpiece 610. Therefore, a pipe hole alignment boss 400 is provided at the pressing head 300. When the pressing head 300 moves toward the base 100, the pipe hole alignment boss 400 first contacts the inner hole of the flange sleeve 620, thereby playing a certain guiding and alignment role for the end of the flange sleeve 620 away from the base 100, preventing the workpiece 610 from being skewed further, and being able to correct the flange sleeve 620 to a certain extent, so that the installation angle of the flange sleeve 620 is more accurate.

[0043] In this embodiment, two of each of the hole positioning posts 200 and the hole alignment bosses 400 are provided, with a one-to-one correspondence between the hole positioning posts 200 and the hole alignment bosses 400. Since the workpiece 610 of this embodiment has two pre-reserved holes and requires installation of two flange sleeves 620, the base 100 is provided with two hole positioning posts 200, and the pressing head 300 is provided with two corresponding hole alignment bosses 400. This allows the two flange sleeves 620 to be precisely pressed into the two pre-reserved holes of the workpiece 610 simultaneously, resulting in high production efficiency.

[0044] It is conceivable that in other embodiments, the tube hole positioning columns 200 and the tube hole alignment bosses 400 may be provided in three, four or more numbers, and those skilled in the art may make specific configurations according to actual needs.

[0045] In the embodiment, the diameters of all the hole locating columns 200 are the same, which facilitates the processing and production of a plurality of hole locating columns 200 and has a relatively simple structure.

[0046] In an embodiment, the end of the tube hole alignment boss 400 close to the tube hole positioning column 200 is tapered, so that when the tube hole alignment boss 400 enters the inner hole end of the flange sleeve 620, if the flange sleeve 620 is skewed, the tapered part can contact and push the flange sleeve 620 to a certain extent to straighten it, and the tube hole alignment boss 400 can smoothly penetrate the inner hole of the flange sleeve 620, so that the installation angle of the flange sleeve 620 is more accurate.

[0047] In this embodiment, the base 100 and the hole locating column 200 are integrally formed, which increases the structural strength of the base 100 and the hole locating column 200 and allows them to be manufactured together. It is understood that in other embodiments, the hole locating column 200 may also be a positioning pin. In this case, a pin hole may be provided in the base 100, and the positioning pin may be inserted into the pin hole to complete the assembly connection between the base 100 and the hole locating column 200.

[0048] In this embodiment, an elastic member 500 is further included. The pressing member 300 is provided with a receiving hole 310. The tube hole alignment boss 400 is retractably disposed in the receiving hole 310 of the pressing member 300. The elastic member 500 is disposed in the receiving hole 310 and is used to drive the tube hole alignment boss 400 to extend. If the flange sleeve 620 is pre-inserted into the reserved through hole of the workpiece 610 at a large skew angle, the tube hole alignment boss 400 may not be able to be inserted into the inner hole of the flange sleeve 620 during the pressing member 300, that is, it cannot assist in aligning the flange sleeve 620. In this case, the tube hole alignment boss 400 may affect the pressing member 300 from being pressed into the flange sleeve 620. Therefore, the tube hole alignment boss 400 is retractable, and the elastic member 500 is provided to keep the tube hole alignment boss 400 extending out of the pressing head member 300. Under normal conditions, the tube hole alignment boss 400 can be inserted into the inner hole of the flange sleeve 620 to align the flange sleeve 620 to a certain extent; when the flange sleeve 620 is skewed, the tube hole alignment boss 400 can be squeezed and pressed into the pressing head member 300 by the flange sleeve 620 to avoid damage to the tube hole alignment boss 400, and the pressing head member 300 can directly press the flange sleeve 620 to complete the press-in installation of the flange sleeve 620.

[0049] Specifically, the elastic member 500 is a spring, one end of which abuts the bottom wall of the receiving hole 310, and the other end of which abuts the tube hole alignment boss 400, thereby keeping the tube hole alignment boss 400 extended. It is conceivable that the elastic member 500 may also be a spring, one end of which abuts the bottom wall of the receiving hole 310, and the other end abuts the tube hole alignment boss 400.

[0050] In the embodiment, the workpiece support surface 101 includes a first planar portion 102, a second planar portion 103, and a connecting surface portion 104. The first planar portion 102 and the second planar portion 103 are arranged parallel and spaced apart. One end of the connecting surface portion 104 is connected to the first planar portion 102, and the other end of the connecting surface portion 104 is connected to the second planar portion 103. The workpiece support surface 101 is adapted to the shape of the workpiece 610, and the connecting surface portion 104 can assist in positioning the workpiece 610, resulting in a good performance.

[0051] Specifically, the base 100 can be made of metal, the pipe hole positioning column 200 can be made of metal, and the pressing head 300 can be made of metal.

[0052] The sleeve press-in tool of the present invention is suitable for press-in installation of the flange sleeve 620. It should be understood that other types of sleeves can also be press-in installed by the sleeve press-in tool of this solution.
