Technical Field
[0001] This utility model belongs to the field of internal support clamp technology, specifically relating to a rubber cone sleeve clamping device for cylinder liners. Background Technology
[0002] Cylinder liners, also known as cylinder liners, are generally cylindrical in shape. When machining the outer surface of a cylinder liner, an internal support fixture is typically used to expand and press against the inner wall of the cylinder liner before it is mounted on machining equipment. This is mainly achieved by a tie rod driving the inner cone to extend and retract, thus expanding the outer cone sleeve and clamping the cylinder liner. Traditional outer cone sleeves typically consist of five individual cone sleeves, such as the double-cone internal support fixture disclosed in patent document CN203459926U. However, the expansion and contraction deformation of each cone sleeve is inconsistent, resulting in poor clamping effect of the internal support fixture. Improved cone sleeve structures, such as... Figure 1 As shown, the gaps between each pair of the five conical sleeves 01 are bonded together with rubber 02 (usually nitrile rubber) to form a single rubber conical sleeve clamp. This clamp opens simultaneously when tightening and retracts simultaneously when releasing, thus improving clamping consistency. However, currently, there is a lack of specialized equipment for filling the rubber between the conical sleeves, which makes the manufacture of rubber conical sleeve clamps difficult and inefficient, hindering their application and promotion. Utility Model Content
[0003] In response to the above situation, this utility model provides a cylinder liner rubber cone sleeve clamp glue injection device, which can assist manual rubber filling between cone sleeves and quickly complete the glue injection and bonding between each cone sleeve.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A cylinder liner rubber cone sleeve clamping and glue injection device includes a cylindrical mold cavity for accommodating five cone sleeves to be injected. The cylindrical mold cavity is symmetrically formed by an upper mold body and a lower mold body. A traveling sleeve is also fitted between the inner surface of the cylindrical mold cavity and the five cone sleeves. An end cap is connected to the front and rear ends of the upper mold body, and a front end cap and a rear end cap are respectively provided at the front and rear ends of the five cone sleeves. The front side of the front end cap and the rear side of the rear end cap respectively abut against the two end caps. A mandrel is coaxially inserted through the center of the front end cap and the rear end cap. A positioning sleeve abuts coaxially at the rear end of the rear end cap. Corresponding clamps are also provided in the gaps between each pair of the five cone sleeves. The device is equipped with five shim keys, and five injection slits for filling rubber are correspondingly provided between the outer sides of the five shim keys and the inner side of the accompanying sleeve. The front end of the mandrel is integrally formed with a stepped head, and the rear end of the mandrel is integrally formed with a lead screw tail. A locking nut is screwed onto the outer side of the lead screw tail. The outer sides of the five conical sleeves are in sliding contact with the inner side of the accompanying sleeve. The five conical sleeves and the shim keys can rotate synchronously with the mandrel inside the accompanying sleeve. An injection channel for injecting rubber into the injection slits is opened on the outer wall of the accompanying sleeve. An injection port corresponding to the injection channel is opened on the top of the upper mold body.
[0006] Furthermore, both the upper mold body and the lower mold body are rectangular block structures. The bottom of the upper mold body and the top of the lower mold body are symmetrically provided with semi-cylindrical grooves for forming the cylindrical mold cavity. The left and right sides of the two semi-cylindrical grooves are detachably pressed together by connecting pins.
[0007] Furthermore, the accompanying sleeve is a cylindrical structure formed by symmetrically fastening two semi-circular arc-shaped tube walls that match the semi-cylindrical grooves. Its outer surface is tightly attached to the inner side of the cylindrical mold cavity, and two sets of directional grooves are symmetrically opened at the fastening seams on the left and right sides of the two semi-circular arc-shaped tube walls. Each directional groove is fitted with a clamping wire to press and connect the two semi-circular arc-shaped tube walls and the two semi-cylindrical grooves together.
[0008] Preferably, three injection channels are equidistantly arranged in the middle of the semi-circular tube wall at the top of the accompanying sleeve along the front-to-back direction, and the top of the upper mold body is provided with an injection port corresponding to the three injection channels.
[0009] Preferably, both end caps are rectangular plate structures, and their four corners are connected to the front and rear ends of the upper mold body by connecting bolts.
[0010] This utility model also includes other components that enable its normal use, all of which are conventional means in the field. In addition, the devices or components not limited in this utility model, such as the five conical sleeves of the rubber conical sleeve clamp and the rubber in the gap between each pair of conical sleeves, all adopt the prior art in the field.

[0020] Example
[0021] like Figure 1-4As shown, a cylinder liner rubber cone sleeve clamping glue injection device includes a cylindrical mold cavity for accommodating five cone sleeves 01 to be injected with glue. The cylindrical mold cavity is symmetrically formed by an upper mold body 1 and a lower mold body 8. Both the upper mold body 1 and the lower mold body 8 are rectangular block structures. Semi-cylindrical grooves are symmetrically opened at the bottom of the upper mold body 1 and the top of the lower mold body 8. The left and right sides of the two semi-cylindrical grooves are detachably pressed and fastened together by connecting pins 12. A traveling sleeve 2 is also provided between the inner side of the cylindrical mold cavity and the five cone sleeves 01.
[0022] The upper mold body 1 has an end cap 3 connected to its front and rear ends respectively. Both end caps 3 are rectangular plate structures, and their four corners are connected to the front and rear ends of the upper mold body 1 respectively by connecting bolts 17.
[0023] The front and rear ends of the five conical sleeves 01 are respectively provided with a front plug 10 and a rear plug 7. The front side of the front plug 10 and the rear side of the rear plug 7 respectively abut against the two end caps 3.
[0024] The front cap 10 and the rear cap 7 are coaxially connected by a spindle 6. The rear end of the rear cap 7 is coaxially abutted against a positioning sleeve 4. Five padding keys 9 are also correspondingly clamped in the gaps between the five conical sleeves 01. Five injection seams for filling rubber 02 are left between the outer side of the five padding keys 9 and the inner side of the accompanying sleeve 2.
[0025] The front end of the spindle 6 is integrally formed with a stepped head 13, and the rear end of the spindle 6 is integrally formed with a lead screw tail 14. A locking nut 5 is screwed on the outside of the lead screw tail 14 to lock the positioning sleeve 4, the rear cover 7, the front cover 10, the five-piece conical sleeve 01, and the gasket key 9 in conjunction with the stepped head 13 of the spindle 6. The outer side of the five-piece conical sleeve 01 is in sliding contact with the inner side of the accompanying sleeve 2. The five-piece conical sleeve 01 and the gasket key 9 can all rotate synchronously with the spindle 6 in the accompanying sleeve 2.
[0026] The accompanying sleeve 2 is a cylindrical structure formed by symmetrically fastening two semi-circular arc-shaped tube walls that match the semi-cylindrical grooves. Its outer surface is tightly attached to the inner side of the cylindrical mold cavity. Two sets of directional grooves are symmetrically opened at the fastening seams on the left and right sides of the two semi-circular arc-shaped tube walls. Each directional groove is fitted with a clamping wire 11 to press and connect the two semi-circular arc-shaped tube walls and the two semi-cylindrical grooves together, so that the two semi-circular arc-shaped tube walls of the accompanying sleeve 2 can move synchronously with the upper mold body 1 and the lower mold body 8.
[0027] The top of the accompanying sleeve 2 has three injection channels 15 arranged equidistantly along the front-to-back direction in the middle of a semi-circular tube wall. The top middle part of the upper mold body 1 has three injection ports 16 arranged in a line along the front-to-back direction, corresponding to the three injection channels 15.
[0028] Since the five conical sleeves 01 and the shim key 9 can all rotate synchronously with the mandrel 6 within the accompanying sleeve 2, meaning that the five injection seams can also rotate within the accompanying sleeve 2, when one of the injection seams rotates to be aligned with the three lined injection channels 15, the rotation of the mandrel 6 can be stopped, and fluid rubber can be injected into the injection seam through the injection port 16. After the injection seam is filled with rubber, the mandrel 6 can be rotated again to align the next injection seam with the injection channel 15, and injection can be performed again, and so on, until all five injection seams are filled with rubber. After the rubber has completely solidified, the upper mold body 1 and the lower mold body 8 can be opened to remove the bonded rubber conical sleeve from the accompanying sleeve 2, and then the production of the next rubber conical sleeve can begin. It should be noted that, in order to ensure the bonding strength between the rubber 02 and the conical sleeve 01, it is best to ensure that the bonding surfaces on both sides of the gap between any two of the five conical sleeves 01 have a certain degree of roughness.
[0029] The technical solution of this utility model is not limited to the specific embodiments described above. Without departing from the scope and spirit of the described embodiments, many modifications and changes will be obvious to those skilled in the art. Any technical modifications made within the spirit and principles of this utility model shall fall within the protection scope of this utility model.
