[0046] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work are within the scope of protection of the present application. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0047] In the description of the present application, the orientation or positional relationship indicated by the terms “upper”, “lower”, “left”, “right”, “front”, “back”, “inner”, “outer” and the like is the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. Unless otherwise specified, the above orientation description can be flexibly arranged in the actual application process under the condition of meeting the relative positional relationship shown in the drawings.

[0048] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms “arrangement”, “installation”, “connection”, “connection” should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For a person of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] Referring to Figure 1 The gun drill 1 is composed of a drill handle 11, a drill rod 12 and a head 13 connected in sequence. The cross-sectional dimension of the head 13 can be as small as 3 mm, and the total length of the head 13 and the drill rod 12 can be as long as 900 mm. Since the inside of the head 13 and the drill rod 12 is designed as a hollow, for the circulation of cutting fluid, the rigidity of the drill rod 12 is relatively poor.

[0050] Referring to Figure 2 In the process of deep hole machining, in order to ensure the rigidity of the drill rod 12, a support 2 needs to be installed on the drill rod 12. The support 2 is usually composed of a bearing and rubber, the outer ring is a bearing, the inner ring is rubber, and the rubber area is provided with a circular hole corresponding to the drill rod 12. However, since the circular hole is smaller than the cross-sectional dimension of the drill rod 12, it is difficult to disassemble and load the support 2.

[0051] At present, the dismounting mode commonly used for the support 2 is that the support 2 is first fixed, and then the drill handle 11 tail is pulled out by the operator. However, since the drill rod 12 is long and has poor rigidity, in the process of manual operation, the pulling force is not always parallel to the axis of the drill rod 12, but has a certain angle. The deflection of the force on the drill rod 12 is easy to cause the drill rod 12 to be bent or the head 13 to be broken. The loading process of the support 2 is opposite to the dismounting process, so the drill rod 12 is also easy to be bent or the head 13 is also easy to be broken when the support 2 is loaded.

[0052] Based on this, referring to Figure 3 、 Figure 4 , the application provides a gun drill support dismounting tool 3, which comprises a fixed seat 31, a movable seat 32 in sliding connection with the fixed seat 31, a driving mechanism 33 for driving the movable seat 32 to move linearly and reciprocally, a gun drill mounting seat 34 and a support mounting seat 35 arranged in sequence along the moving direction of the movable seat 32, the gun drill mounting seat 34 being connected with the fixed seat 31, and the support mounting seat 35 being connected with the movable seat 32.

[0053] The fixed seat 31 is used for mounting and supporting the movable seat 32; the movable seat 32 is arranged above the fixed seat 31 and is in sliding connection with the fixed seat 31, so that the movable seat 32 can slide relative to the fixed seat 31; the driving mechanism 33 is arranged between the movable seat 32 and the fixed seat 31 and is used for providing power to drive the movable seat 32 to move linearly and reciprocally on the fixed seat 31.

[0054] The gun drill mounting seat 34 and the support mounting seat 35 are arranged above the movable seat 32 and are arranged in sequence along the moving direction of the movable seat 32; the gun drill mounting seat 34 is connected with the fixed seat 31 and is used for mounting the gun drill 1, and the support mounting seat 35 is connected with the movable seat 32 and is used for mounting the support 2; when the movable seat 32 moves linearly and reciprocally, the movable seat 32 can drive the support mounting seat 35 to move linearly and approach or move away from the gun drill mounting seat 34. The gun drill mounting seat 34 can be connected with the fixed seat 31 through a gun drill mounting block 36, and the support mounting seat 35 can be connected with the movable seat 32 through a support mounting block 37.

[0055] The gun drill support dismounting tool 3 provided by the application is used for dismounting and mounting the support 2 on the gun drill 1, and the dismounting process mainly comprises a dismounting process and a loading process, and the specific operation is as follows.

[0056] Dismounting process: first, install the gun drill 1 on the gun drill mounting seat 34, and adjust the position of the gun drill 1 so that the axis of the gun drill 1 is parallel to the moving direction of the movable seat 32; then install the support piece 2 on the support mounting seat 35; and then drive the movable seat 32 to move linearly by using the driving mechanism 33, so that the movable seat 32 drives the support mounting seat 35 and the support piece 2 thereon to move away from the gun drill mounting seat 34, thereby dismounting the support piece 2 from the drill rod 12 of the gun drill 1. After the dismounting of the first support piece 2 is completed, the above operation is repeated to complete the dismounting of the remaining support pieces 2.

[0057] Loading process: first, install the gun drill 1 on the gun drill mounting seat 34, and adjust the position of the gun drill 1 so that the axis of the gun drill 1 is parallel to the moving direction of the movable seat 32; then install the support piece 2 on the support mounting seat 35, and adjust the position of the support piece 2 so that the circular hole of the rubber area of the support piece 2 is aligned with the head 13 of the gun drill 1; then drive the movable seat 32 to move linearly by using the driving mechanism 33, so that the movable seat 32 drives the support mounting seat 35 and the support piece 2 thereon to move towards the gun drill mounting seat 34, thereby loading the support piece 2 on the drill rod 12 of the gun drill 1. After the loading of the first support piece 2 is completed, the above operation is repeated to complete the loading of the remaining support pieces 2.

[0058] The gun drill support dismounting and loading tool 3 provided by the embodiments of the present application can always ensure that the dragging force is parallel to the axis of the drill rod 12 by driving the movable seat 32 to move linearly by using the driving mechanism 33 to provide the dragging force, thereby avoiding the bending of the drill rod 12 or the breaking of the head 13, and improving the dismounting and loading efficiency.

[0059] In the dismounting and loading process, when the gun drill 1 is installed on the gun drill mounting seat 34, the position of the gun drill 1 can be adjusted by using an auxiliary positioning tool, so that the axis of the gun drill 1 is parallel to the moving direction of the movable seat 32.

[0060] In order to improve the installation efficiency of installing the gun drill 1 on the gun drill mounting seat 34, in some embodiments, a gun drill positioning portion is arranged on the gun drill mounting seat 34, and the gun drill positioning portion is used for positioning the gun drill 1 and making the axis of the gun drill 1 parallel to the moving direction of the movable seat 32.

[0061] When installing, the gun drill 1 is only needed to be placed on the gun drill mounting seat 34 and positioned by the gun drill positioning part, so that the axis of the gun drill 1 is parallel to the moving direction of the movable seat 32, without repeatedly adjusting the position of the gun drill 1 by using an auxiliary positioning tool, thereby greatly improving the installation efficiency of installing the gun drill 1 on the gun drill mounting seat 34, and further improving the dismounting efficiency of the support piece 2. After the gun drill 1 is positioned on the gun drill mounting seat 34, the gun drill 1 can be fixed on the gun drill mounting seat 34 by means of artificial pressing, pressing plate fixing, clamping mechanism fixing and the like, to prevent relative displacement between the gun drill 1 and the gun drill mounting seat 34 along the axis direction of the gun drill 1 during the dismounting process.

[0062] For example, referring to Figure 3 , the gun drill positioning part comprises a drill rod positioning part 341 and / or a drill handle positioning part 342, the drill rod positioning part 341 is used for positioning the drill rod 12, and the drill handle positioning part 342 is used for positioning the drill handle 11.

[0063] When installing, the gun drill 1 is only needed to be placed on the gun drill mounting seat 34 and positioned by the gun drill positioning part, so that the axis of the gun drill 1 is parallel to the moving direction of the movable seat 32, without repeatedly adjusting the position of the gun drill 1 by using an auxiliary positioning tool, thereby greatly improving the installation efficiency of installing the gun drill 1 on the gun drill mounting seat 34, and further improving the dismounting efficiency of the support piece 2. After the gun drill 1 is positioned on the gun drill mounting seat 34, the gun drill 1 can be fixed on the gun drill mounting seat 34 by means of artificial pressing, pressing plate fixing, clamping mechanism fixing and the like, to prevent relative displacement between the gun drill 1 and the gun drill mounting seat 34 along the axis direction of the gun drill 1 during the dismounting process.

[0064] In some embodiments, referring to Figure 5 , the gun drill mounting seat 34 comprises a drill rod supporting rod 343 and a drill handle supporting handle 344; the drill rod supporting rod 343 and the drill handle supporting handle 344 are both long strip structures, the length directions of the two are parallel to the moving direction of the movable seat 32, and one end of the drill rod supporting rod 343 is fixedly connected with one end of the drill handle supporting handle 344. The top of the drill rod supporting rod 343 is provided with the drill rod positioning part 341, so that the drill rod 12 can be supported and positioned by the drill rod supporting rod 343; the top of the drill handle supporting handle 344 is provided with the drill handle positioning part 342, so that the drill handle 11 can be supported and positioned by the drill handle supporting handle 344.

[0065] The drill rod positioning part 341 can comprise a drill rod positioning groove provided on the top of the drill rod supporting rod 343, the drill rod positioning groove is a long strip groove extending along the moving direction of the movable seat 32, and the cross-sectional shape and size of the drill rod positioning groove are consistent with the cross-sectional shape and size of the drill rod 12. When installing, the drill rod 12 is only needed to be placed in the drill rod positioning groove, so that the drill rod 12 can be radially positioned by the drill rod positioning groove, to ensure that the axis of the drill rod 12 is parallel to the moving direction of the movable seat 32.

[0066] The drill rod positioning portion 341 can further include a plurality of drill rod positioning columns arranged on the top of the drill rod supporting rod 343, and the positioning space for positioning the drill rod 12 is formed between the plurality of drill rod positioning columns. During installation, the drill rod 12 is only needed to be placed in the positioning space between the plurality of drill rod positioning columns, and the drill rod 12 is radially positioned by the drill rod positioning columns to ensure that the axis of the drill rod 12 is parallel to the moving direction of the movable seat 32.

[0067] The drill handle positioning portion 342 can include a drill handle positioning groove arranged on the top of the drill handle supporting handle 344, and the cross-sectional shape and size of the drill handle positioning groove are consistent with the cross-sectional shape and size of the drill handle 11. During installation, the drill handle 11 is only needed to be placed in the drill handle positioning groove, and the drill handle 11 is radially positioned by the drill handle positioning groove to ensure that the axis of the drill rod 12 is parallel to the moving direction of the movable seat 32. Since the cross-sectional size of the drill handle 11 is larger than the cross-sectional size of the drill rod 12, the drill handle positioning groove can also play a role in positioning the axis of the drill handle 11 after being arranged.

[0068] The drill handle positioning portion 342 can further include a plurality of drill handle positioning columns arranged on the top of the drill handle supporting handle 344, and the positioning space for positioning the drill handle 11 is formed between the plurality of drill handle positioning columns. During installation, the drill handle 11 is only needed to be placed in the positioning space between the plurality of drill handle positioning columns, and the drill handle 11 is radially and axially positioned by the drill handle positioning columns, which not only ensures that the axis of the drill rod 12 is parallel to the moving direction of the movable seat 32, but also prevents the displacement between the drill handle 11 and the drill handle supporting handle 344 along the axis of the drill handle 11 during disassembly and assembly.

[0069] During disassembly and assembly, when the support 2 is installed on the support mounting seat 35, the position of the support 2 can be adjusted by the auxiliary positioning tool to align the circular hole of the rubber area in the support 2 with the head 13 of the gun drill 1.

[0070] In order to improve the installation efficiency of the support 2 on the support mounting seat 35, in some embodiments, the support mounting seat 35 is provided with a support positioning portion for positioning the support 2.

[0071] During installation, the support 2 is only needed to be placed on the support mounting seat 35 and positioned by the support positioning portion, so that the circular hole of the rubber area in the support 2 is aligned with the head of the gun drill 1, without the need for repeatedly adjusting the position of the support 2 by the auxiliary positioning tool, thereby greatly improving the installation efficiency of the support 2 on the support mounting seat 35, and further improving the disassembly and assembly efficiency of the support 2. When the support 2 is positioned on the support mounting seat 35, the support 2 can be fixed on the support mounting seat 35 by artificial pressing, pressing plate fixing, clamping mechanism fixing, etc., to prevent the relative displacement between the support 2 and the support mounting seat 35 along the axis of the gun drill 1 during disassembly and assembly.

[0072] For example, referring to Figure 3 , Figure 6 , the support positioning part includes a support positioning groove 351 arranged on the support mounting seat 35 and facing the side of the gun drill mounting seat 34, and the bottom of the support positioning groove 351 is provided with an avoiding hole 352 for the drill rod 12 and the head 13 to pass through.

[0073] Specifically, the support mounting seat 35 is cylindrical, and the axis thereof is parallel to the moving direction of the movable seat 32, and the support positioning groove 351 is arranged on the end face of the end of the support mounting seat 35 facing the gun drill mounting seat 34; the support positioning groove 351 is a cylindrical groove, and the diameter thereof is consistent with the outer diameter of the bearing in the support piece 2.

[0074] During installation, the support piece 2 is only needed to be placed in the support positioning groove 351, so that the support piece 2 is positioned by the support positioning groove 351, to ensure that the circular hole in the rubber area of the support piece 2 is aligned with the head of the gun drill 1. During disassembly, the drill rod 12 and the head 13 can pass through the avoiding hole 352 at the bottom of the support positioning groove 351.

[0075] The support positioning part can also include a plurality of support positioning columns arranged on the end face of the end of the support mounting seat 35 facing the gun drill mounting seat 34, and the positioning space for positioning the support piece 2 is formed between the plurality of support positioning columns. During installation, the support piece 2 is only needed to be placed in the positioning space between the plurality of support positioning columns, so that the support piece 2 is positioned, to ensure that the circular hole in the rubber area of the support piece 2 is aligned with the head of the gun drill 1.

[0076] In some embodiments, referring to Figure 7 , the driving mechanism 33 includes a lead screw 331 and a fixed block 332 threadedly connected to the lead screw 331, and the lead screw 331 is parallel to the moving direction of the movable seat 32 and is rotationally connected with the movable seat 32, and the fixed block 332 is connected with the fixed seat 31. During use, the movable seat 32 is only needed to be driven to move linearly on the fixed seat 31 by rotating the lead screw 331.

[0077] For example, the lead screw 331 is arranged between the fixed seat 31 and the movable seat 32, both ends of the lead screw 331 are connected with the movable seat 32 through bearing structures, so that the lead screw 331 can rotate around its axis, and the fixed block 332 is threadedly connected to the lead screw 331 and is connected with the fixed seat 31 through bolts.

[0078] In order to facilitate the control of the rotation of the lead screw 331, in some embodiments, referring to Figure 7 , at least one end of the lead screw 331 is provided with a handle 333. Correspondingly, the handle 333 is designed so that the operator can easily control the forward and reverse rotation of the lead screw 331 without using tools, thereby improving the convenience of operation.

[0079] In other embodiments, the driving mechanism 33 can also include a linear motor, an electric push rod, a hydraulic cylinder, or the like linear actuator.

[0080] In some embodiments, referring to Figure 7 , the bottom of the movable seat 32 is provided with a sliding rail 321, and the top of the fixed seat 31 is provided with a sliding groove 311 that is in sliding cooperation with the sliding rail 321. Accordingly, by using the cooperation between the sliding rail 321 and the sliding groove 311, the movable seat 32 can be freely slid along the sliding rail 321 on the fixed seat 31, facilitating the quick adjustment and accurate positioning of the position of the movable seat 32. Of course, other guiding structures such as a sliding rail and sliding block structure can also be used between the movable seat 32 and the fixed seat 31 for guiding.

[0081] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application.
