The above patent uses a fixed component structure to achieve the function of cylinder bottom clamping. However, due to the unstable clamping of the cylinder bottom, the accuracy of cylinder bottom boring is not good. Therefore, in order to advance the industry's technology, better realize the cylinder bottom boring function, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the clamping structure and application method of horizontal boring machines in the prior art. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the cylinder bottom boring accuracy is poor due to the unstable clamping of the cylinder bottom during the use of existing adjustable horizontal boring machines, and to propose an adjustable horizontal boring machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable horizontal boring machine includes an adjustable boring machine structure. A first lead screw is rotatably inserted between the two ends of the top of the main body. A bottom block is threaded onto the outer wall of the first lead screw. A support seat is rotatably connected to the top of the bottom block. A bidirectional threaded rod is rotatably inserted between the inner walls of the two ends of the support seat. A sliding plate is threaded onto both ends of the bidirectional threaded rod. The sliding plate slides on the top of the support seat. A side frame is fixedly connected to one side of the sliding plate. A side clamping plate is fixedly connected to the top of the side frame. An adjusting threaded rod is rotatably inserted between the bottom inner wall and the top of the side frame. An upper clamping plate is threaded onto the outer wall of the adjusting threaded rod.

[0007] Furthermore, the adjustable boring machine structure includes a main body, a vertical seat fixedly connected to the top of the main body, a first motor fixedly connected to the top of the vertical seat, a second lead screw keyed to the output end of the first motor, a sliding seat threaded onto the outer wall of the second lead screw, the sliding seat sliding on one side of the vertical seat, a spindle box fixedly connected to one side of the sliding seat, a boring spindle rotatably inserted through the spindle box, and a boring tool fixedly connected to one end of the boring spindle.

[0008] Furthermore, two vertical rods are fixedly connected between the bottom inner wall and the top inner wall of the side frame, and the upper clamping plate is slidably sleeved between the two vertical rods.

[0009] Furthermore, a first anti-slip pad is adhered to the bottom of the upper clamping plate.

[0010] Furthermore, a second anti-slip pad is adhered to one end of the side clamp.

[0011] Furthermore, two positioning arc blocks are fixedly connected to the top of the support.

[0012] Furthermore, a mounting shell is fixedly connected to the top of the base block, and a worm gear is rotatably inserted between the inner walls of both sides of the mounting shell.

[0013] Furthermore, a rotating column is rotatably inserted into the top of the mounting shell, the top end of the rotating column is fixedly connected to the bottom of the support, and a worm gear is keyed to the outer wall of the rotating column, which meshes with a worm.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By turning the double-threaded rod, the two sliding plates are brought together in the middle, thereby driving the side clamping plate to move and contact the cylinder bottom, and then clamping it from both sides of the cylinder bottom.

[0016] 2. Driven by the second motor, the first lead screw rotates, thereby moving the bottom block, which in turn moves the support seat and the cylinder bottom on it, thus moving the cylinder bottom to the side of the boring tool for machining.

[0017] 3. By engaging the worm gear and worm wheel, the rotating column is driven to rotate, which in turn drives the support seat to rotate, and then drives the cylinder bottom to rotate. This adjusts the machining angle of the cylinder bottom and improves the machining quality. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 An adjustable horizontal boring machine includes an adjustable boring machine structure 1. The adjustable boring machine structure 1 includes a main body 101. A vertical seat 103 is bolted to the top of the main body 101. A first motor 108 is bolted to the top of the vertical seat 103. A second lead screw 104 is keyed to the output end of the first motor 108. A sliding seat 105 is threaded onto the outer wall of the second lead screw 104. The sliding seat 105 slides on one side of the vertical seat 103. A spindle box 106 is bolted to one side of the sliding seat 105. A boring spindle 107 is rotatably inserted through the spindle box 106. A boring tool is bolted to one end of the boring spindle 107. Driven by the first motor 108, the second lead screw 104 rotates, thereby causing the sliding seat 105 to move downward, which in turn causes the boring spindle 107 and the boring tool to move and contact the bottom of the cylinder, thereby machining the bottom of the cylinder.

[0026] A second motor is fixed to one end of the main body 101 by bolts. A first lead screw 102 is rotatably inserted between the two ends of the top of the main body 101. The output end of the second motor is fixedly connected to one end of the first lead screw 102. A bottom block 14 is threaded onto the outer wall of the first lead screw 102. A support seat 2 is rotatably connected to the top of the bottom block 14. Driven by the second motor, the first lead screw 102 rotates, thereby driving the bottom block 14 to move, and then driving the support seat 2 and the cylinder bottom on it to move, so as to send the cylinder bottom to the boring tool side.

[0027] A bidirectional threaded rod 3 is rotatably inserted between the inner walls of both ends of the support 2. Both ends of the bidirectional threaded rod 3 are threaded with sliding plates 4. The sliding plates 4 slide on the top of the support 2. A side frame 5 is fixed to one side of the sliding plate 4 by bolts. A side clamping plate 6 is fixed to the top of the side frame 5 by bolts. Tightening the bidirectional threaded rod 3 causes the two sliding plates 4 to converge towards the middle, thereby driving the side clamping plate 6 to move and contact the cylinder bottom, and then clamping it from both sides of the cylinder bottom.

[0028] An adjusting threaded rod 7 is rotatably inserted between the bottom inner wall and the top of the side frame 5. An upper clamping plate 9 is threadedly sleeved on the outer wall of the adjusting threaded rod 7. Two vertical rods 8 are welded between the bottom inner wall and the top inner wall of the side frame 5. The upper clamping plate 9 is slidably sleeved between the two vertical rods 8. Tightening the adjusting threaded rod 7 causes the upper clamping plate 9 to move downward along the vertical rods 8, thereby pressing the upper clamping plate 9 onto the cylinder bottom and fixing the cylinder bottom.

[0029] A first anti-slip pad 10 is bonded to the bottom of the upper clamping plate 9, and a second anti-slip pad 11 is bonded to one end of the side clamping plate 6. The first anti-slip pad 10 and the second anti-slip pad 11 increase the friction between the upper clamping plate 9 and the side clamping plate 6 and the cylinder bottom, improving the stability of the cylinder bottom. Two positioning arc blocks 12 are fixed to the top of the support 2 by bolts, which facilitates the positioning of the cylinder bottom. The support 2 has multiple mounting holes. If the cylinder specification is changed, the position of the positioning arc blocks 12 can be changed by removing the bolts to accommodate cylinders of different diameters. The bottom block 14... A mounting shell 13 is bolted to the top. A worm gear 17 is rotatably inserted between the inner walls of both sides of the mounting shell 13. A rotating column 15 is rotatably inserted to the top of the mounting shell 13. The top of the rotating column 15 is fixedly connected to the bottom of the support seat 2. A worm wheel 16 is keyed to the outer wall of the rotating column 15. The worm wheel 16 meshes with the worm gear 17. Tightening the worm gear 17 causes the rotating column 15 to rotate under the action of the worm gear 17 meshing with the worm wheel 16, thereby causing the support seat 2 to rotate, and then causing the cylinder bottom to rotate, thus adjusting the machining angle of the cylinder bottom.

[0030] The working principle of this embodiment is as follows: In use, firstly, the cylinder bottom is placed on top of the support 2 and positioned between the two positioning arc blocks 12. Then, the bidirectional threaded rod 3 is turned to bring the two sliding plates 4 together in the middle, thereby causing the side clamping plate 6 to move and contact the cylinder bottom, thus clamping it from both sides. Next, the adjusting threaded rod 7 is turned to move the upper clamping plate 9 downward along the vertical rod 8, thereby pressing the upper clamping plate 9 onto the cylinder bottom and fixing it in place. Then, the second motor is started, and under the drive of the second motor, the first lead screw 102 rotates, thereby moving the bottom block 14. This causes the support seat 2 and the cylinder bottom on it to move, thus moving the cylinder bottom to the boring tool side. Then, the first motor 108 is started, and the second lead screw 104 rotates under the drive of the first motor 108, thereby causing the sliding seat 105 to move downward, which in turn causes the boring shaft 107 and the boring tool to move and contact the cylinder bottom, thereby machining the cylinder bottom. During the machining process, the worm gear 17 is turned, and under the action of the worm gear 17 meshing with the worm wheel 16, the rotating column 15 rotates, thereby causing the support seat 2 to rotate, which in turn causes the cylinder bottom to rotate, thus adjusting the machining angle of the cylinder bottom.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
