[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The present application embodiment discloses a heat shrinkable sleeve machine. Figure 1 and Figure 2 The shrink fitting machine includes a machine body 3, a shell material rack 4, an end cover material rack 5, a shell grabbing assembly 6, an extrusion piece 7 and a heating piece 8 arranged on the machine body 3. The shell material rack 4 and the end cover material rack 5 are both hollow frame structures. The shell 1 is placed on the shell material rack 4, and the end cover 2 is placed on the end cover material rack 5. After the shell grabbing assembly 6 grabs the shell 1, the shell 1 is sent to the heating piece 8 for heating, and then the shell 1 is placed on the end cover 2; then the extrusion piece 7 moves downward and squeezes the shell 1 and the end cover 2 together, thereby realizing the connection between the shell 1 and the end cover 2.

[0035] Reference Figure 1 and Figure 2 The shell grabbing assembly 6 includes a horizontal sliding portion 61, a vertical sliding portion 62 and a grabbing portion 63 connected to the vertical sliding portion 62. The horizontal sliding portion 61 and the vertical sliding portion 62 can be implemented using a cross module structure in the prior art. That is, the horizontal sliding portion 61 is a linear module for horizontal linear motion, such as a screw drive or the like, and the vertical sliding portion 62 is installed on the horizontal sliding portion 61, so that the vertical sliding portion 62 can be driven to move linearly in the horizontal direction through the horizontal sliding portion 61, and the horizontal movement direction of the vertical sliding portion 62 is parallel to the connection line between the shell material rack 4 and the end cover material rack 5. In other embodiments, the horizontal sliding portion 61 can also be implemented by a walking chain, a cylinder drive, etc., as long as the horizontal movement of the vertical sliding portion 62 can be achieved.

[0036] In this embodiment, the vertical sliding part 62 is preferably a cylinder, and the cylinder body of the cylinder is connected to the horizontal sliding part 61, and the piston rod of the cylinder is connected to the grabbing part 63. The cylinder is arranged vertically, so that the grabbing part 63 can be driven to move in the vertical direction by the cylinder. In other embodiments, the vertical sliding part 62 can also be a device that can achieve up and down reciprocating motion, such as a linear telescopic cylinder.

[0037] In a further embodiment, the grabbing part 63 includes a seat body 631 and a clamp 632 installed on the seat body 631, and the seat body 631 is connected to the vertical sliding part 62. That is, the movable part of the vertical sliding part 62 is fixedly connected to the seat body 631, so that the seat body 631 is driven to move up and down by the vertical sliding part 62. The clamp 632 is installed on the downward side of the seat body 631, and the clamp 632 is preferably a clamping claw cylinder. The horizontal sliding part 61 drives the vertical sliding part 62 to move horizontally, so that the clamp 632 can move to the top of the shell material rack 4, and then the vertical sliding part 62 drives the seat body 631 to move downward, and the clamping claw cylinder can clamp on the shell 1, so as to grab the shell 1, and then transport it to the back station.

[0038] Reference Figure 1 and Figure 3 The heating element 8 includes a power source 81 and a heating tube disc 82 connected to the power source 81. The heating tube disc 82 is arranged around and has a certain space formed inside. The heating tube disc 82 can be a device for electric heating tube heating, and the power source 81 is a power supply box-shaped structure connected to the heating tube disc 82. After the clamp 632 grabs the shell 1, it moves upward and resets, and then the horizontal sliding part 61 drives the seat 631 to move above the heating tube disc 82, and the vertical sliding part 62 moves downward to send the shell 1 into the inner cavity of the heating tube disc 82 for heating. The inner cavity of the heating tube disc 82 is larger than the outer diameter of the shell 1, thereby reducing direct contact heating.

[0039] The extrusion member 7 is a cylinder, and a frame is installed on the machine body 3 to provide necessary installation for the extrusion member 7. The extrusion member 7 is located directly above the end cover material rack 5. After the shell 1 is placed on the end cover 2, the piston rod of the cylinder moves downward and squeezes the shell 1 and the end cover 2 together.

[0040] In a further embodiment, referring to Figure 2 and Figure 3 , an extension plate 9 is fixed on the seat body 631, and the extension plate 9 is fixed to the lower surface of the seat body 631 by means of two bolt rods, and the extension plate 9 is located in the clamping space of the clamp 632, that is, between the two clamping claws of the clamping claw cylinder. When the seat body 631 moves downward and the clamp 632 clamps the shell 1, the upper end of the shell 1 can abut against the extension plate 9, so that the position of the clamp 632 clamping the shell 1 is basically consistent each time. And in order to improve the clamping effect, the clamping claw of the clamp 632 is set to an arc-shaped structure that matches the outer wall of the shell 1.

[0041] Reference Figure 2 and Figure 3In a further embodiment, a boss 10 extending upward is fixed on the shell material rack 4. When the shell 1 is placed on the shell material rack 4, the boss 10 can be inserted into the inner cavity of the shell 1, thereby positioning the shell 1. Further, in order to improve the stability of the shell 1 placed on the shell material rack 4, an elastic member 11 is provided on the side wall of the boss 10. After the shell 1 is placed on the boss 10, the elastic member 11 can abut against the inner wall of the shell 1, thereby further improving the stability of the shell 1 and preventing it from tipping over. In this embodiment, the elastic member 11 is selected from a ball plunger, and a corresponding hole groove is provided on the boss 10 to provide a space for installing the ball plunger.

[0042] In a further embodiment, a limiting member 12 is further installed on the body 3, and the limiting member 12 includes a support plate 121 and a limiting rod 122 installed on the support plate 121. In this embodiment, the specific installation position of the support plate 121 is not limited. The support plate 121 can be installed on the upper surface of the body 3, the side wall of the power source 81, and the lower surface of the horizontal sliding portion 61, as long as the support plate 121 does not interfere with the movement of the vertical sliding portion 62. In this embodiment, the horizontal plate is fixed to the outer wall of the housing 1 of the power source 81. The limiting member 12 corresponds to the position of the heating tube disc 82. When the seat body 631 moves downward, the housing 1 enters the space of the heating tube disc 82, and the end of the limiting rod 122 can abut against the lower surface of the seat body 631, thereby limiting the distance of the seat body 631 moving downward. The limiting rod 122 can be threadedly connected to the support plate 121, so as to facilitate disassembly and installation, and can adjust the vertical height to a certain extent.

[0043] Further, see Figure 4 At least two positioning posts 13 extending upward are fixed on the upper surface of the end cover 2 placement frame. The positioning posts 13 are used to be inserted into the holes of the end cover 2 to position the end cover 2.

[0044] The implementation principle of a heat sleeve machine in an embodiment of the present application is as follows: the grabbing portion 63 grabs the shell 1, and with the cooperation of the horizontal sliding portion 61 and the vertical sliding portion 62, the shell 1 is sent into the heating tube disc 82 for heating, and then placed on the end cover 2, and then the shell 1 and the end cover 2 are connected together under the action of the extrusion member 7.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
