Utility Model Content

[0004] The purpose of this utility model is to provide a cutting head for a hydraulic four-column flat cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting head for a hydraulic four-column flat cutting machine, comprising a hydraulic main frame and a push rod frame fixedly mounted on the hydraulic main frame. A hydraulic rod is disposed inside the push rod frame, a lifting platform is fixedly mounted at the bottom end of the hydraulic rod, and a mounting frame is fixedly mounted at the bottom of the lifting platform. A connecting frame is snapped into the mounting frame, and a cutting head body is fixedly mounted at the bottom of the connecting frame. A snap-fit ​​groove is formed on the surface of the connecting frame. A first limiting component is disposed inside the mounting frame, and a clamping component is disposed between the first limiting component and the snap-fit ​​groove. A push head is fixedly mounted at the top of the connecting frame, and a pushing component is disposed between the push head and the mounting frame. A locking component is disposed between the pushing component, the mounting frame, and the clamping component. A second limiting component is disposed between the lifting platform and the hydraulic main frame.

[0006] In a preferred embodiment, the first limiting component includes a limiting ring fixedly installed inside the mounting bracket, and the limiting ring has a limiting groove for limiting.

[0007] In a preferred embodiment, the clamping assembly includes a pusher frame slidably connected inside the limiting ring, a push rod being contacted and connected to the inner side of the pusher frame, a snap-fit ​​block being fixedly installed at the bottom end of the push rod, the snap-fit ​​block being snapped into a snap-fit ​​groove, the push rod being slidably connected in the limiting groove, an adjusting rod being fixedly installed on the surface of the pusher frame, and an adjusting gear being fixedly installed at one end of the adjusting rod.

[0008] In a preferred embodiment, the mounting bracket has an adjustment groove, and the adjustment rod is slidably connected in the adjustment groove.

[0009] In a preferred embodiment, the pushing assembly includes a telescopic rod slidably connected within the mounting frame. One end of the telescopic rod is fixedly fitted with a pushing ball that contacts the push head, and the other end of the telescopic rod is fixedly fitted with a limiting plate. A spring is fixedly fitted between the limiting plate and the telescopic rod, and one side of the limiting plate contacts a locking assembly.

[0010] In a preferred embodiment, the locking assembly includes a fixed frame fixedly mounted on one side of the mounting bracket, an adjusting plate rotatably connected to the inner side of the fixed frame, a limiting tooth fixedly mounted on the inner side of the fixed frame, the limiting tooth engaging with the clamping assembly, and a pushed plate fixedly mounted on the top of the adjusting plate, the pushed plate contacting the pushing assembly.

[0011] In a preferred embodiment, the second limiting component includes a limiting sleeve fixedly installed on the lifting platform, and the limiting sleeve is internally slidably connected to a limiting rod fixedly installed inside the hydraulic main frame.

[0012] In a preferred embodiment, a positioning sleeve is fixedly installed on the inner side of the mounting bracket, and the connecting bracket is slidably connected inside the positioning sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The cutting head of this hydraulic four-column flat cutting machine uses an adjusting gear in the clamping assembly. When the adjusting gear is rotated, the adjusting gear drives the adjusting rod to rotate, which in turn drives the push frame, which is fixedly installed with the adjusting rod, to rotate. The push frame causes the internal inclined groove to change angle, thereby pushing the pushed rod to move. At this time, the limiting groove restricts the movement of the pushed rod, allowing it to move forward simultaneously or sequentially. The moving pushed rod can drive the locking block to move, and the moving locking block can lock and fix the locking groove of the connecting frame, thus making the installation and operation of the cutting head simpler and the clamping installation very stable.

[0015] The cutting head of this hydraulic four-column flat cutting machine, through the setting of an adjustment plate and a limiting tooth, can engage and limit the adjustment gear. At the same time, pulling the adjustment plate causes the adjustment plate to rotate, causing the adjustment plate and the limiting tooth to disengage from the adjustment gear. Simultaneously, it drives the pushed plate to rotate, and the pushed plate pushes the limiting plate, the telescopic rod, and the pushing ball to move inward as a whole. The pushing ball pushes the push head, the connecting frame, and the cutting head body downward, thereby further assisting in the disassembly of the cutting head body in a more efficient and safe manner.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0026] Please see Figures 1-3 This utility model provides a cutting head for a hydraulic four-column flat cutting machine, including a hydraulic main frame 1 and a push rod frame 2 fixedly installed on the hydraulic main frame 1. A hydraulic rod 3 is provided inside the push rod frame 2. A lifting platform 6 is fixedly installed at the bottom of the hydraulic rod 3. A mounting frame 7 is fixedly installed at the bottom of the lifting platform 6. A connecting frame 8 is snapped into the mounting frame 7. A cutting head body 4 is fixedly installed at the bottom of the connecting frame 8. A snap-fit ​​groove 12 is formed on the surface of the connecting frame 8. A first limiting component 13 is provided inside the mounting frame 7. The first limiting component 13 includes a limiting ring 131 fixedly installed inside the mounting frame 7. A limiting groove 132 for limiting is formed on the limiting ring 131. A clamping assembly is provided between the first limiting component 13 and the snap-fit ​​groove 12. Component 11, clamping assembly 11 includes a pusher 113 slidably connected inside the limiting ring 131. The pusher 113 has a uniformly inclined groove on its inner side. A push rod 114 is contacted and connected to the inner side of the pusher 113. A snap-fit ​​block 115 is fixedly installed at the bottom end of the push rod 114. The snap-fit ​​block 115 snaps into the snap-fit ​​groove 12. The push rod 114 is slidably connected in the limiting slide groove 132. An adjusting rod 111 is fixedly installed on the surface of the pusher 113. An adjusting gear 112 is fixedly installed at one end of the adjusting rod 111. An adjusting slide groove 10 is opened inside the mounting frame 7. The adjusting rod 111 is slidably connected in the adjusting slide groove 10. A positioning sleeve 16 is fixedly installed inside the mounting frame 7. A connecting frame 8 is slidably connected in the positioning sleeve 16.

[0027] In the above solution, it should be noted that the hydraulic main frame 1 in this application is an existing hydraulic four-column flat cutting machine, and the specific structure and drive control components inside the hydraulic main frame 1 are the same as those of the existing hydraulic four-column flat cutting machine. This is a technical means disclosed in this field, and will not be described in detail here.

[0028] In this embodiment, when the adjusting gear 112 in the rotating clamping assembly 11 is rotated, the adjusting gear 112 drives the adjusting rod 111 to rotate, thereby driving the push frame 113, which is fixedly installed with the adjusting rod 111, to rotate as well. The push frame 113 drives the internal inclined groove to change angle, thereby pushing the pushed rod 114 to move. At this time, in conjunction with the limiting slide groove 132, the movement position of the pushed rod 114 is restricted, so that it can be pushed forward at the same time or one after the other. At this time, the moving pushed rod 114 can drive the locking block 115 to move. The moving locking block 115 can lock and fix the locking groove 12 of the connecting frame 8. Conversely, rotating the adjusting gear 112 can release the locking groove 12 of the connecting frame 8.

[0029] Please see Figure 1 , Figure 4 and Figure 5 A push head 9 is fixedly installed at the top of the connecting frame 8. The push head 9 has a conical structure. A pushing assembly 14 is provided between the push head 9 and the mounting frame 7. The pushing assembly 14 includes a telescopic rod 143 that is slidably connected in the mounting frame 7. A pushing ball 141 that contacts the push head 9 is fixedly installed at one end of the telescopic rod 143. A limiting plate 144 is fixedly installed at the other end of the telescopic rod 143. A spring 142 is fixedly installed between the limiting plate 144 and the telescopic rod 143. One side of the limiting plate 144 contacts the locking assembly 15.

[0030] In this embodiment, when the connecting frame 8 is being installed, the connecting frame 8 pushes the push head 9 upward, and the push head 9 pushes the push ball 141 outward. The push ball 141 drives the telescopic rod 143 and the limiting plate 144 to push the locking assembly 15, which can adjust and control the locking assembly 15. At the same time, when the locking assembly 15 is adjusted in the opposite direction, the spring 142 can drive the limiting plate 144 to move, thereby driving the telescopic rod 143 to move in the direction of the push head 9, which can help to push the push head 9 and the connecting frame 8 downward, and assist in the disassembly work.

[0031] Please see Figure 1 , Figure 4 and Figure 6 A locking component 15 is provided between the pushing component 14, the mounting frame 7, and the clamping component 11. The locking component 15 includes a fixed frame 151 fixedly installed on one side of the mounting frame 7. An adjusting plate 152 is rotatably connected to the inner side of the fixed frame 151. A limiting tooth 153 is fixedly installed on the inner side of the fixed frame 151. The limiting tooth 153 meshes with the clamping component 11. A pushed plate 154 is fixedly installed on the top of the adjusting plate 152. The pushed plate 154 is in contact with the pushing component 14.

[0032] In this embodiment, when the push plate 154 inside the locking assembly 15 is pushed outward, the push plate 154 drives the adjusting plate 152 and the limiting tooth 153 to approach the clamping assembly 11, and the limiting tooth 153 can engage and limit the clamping assembly 11.

[0033] Please see Figure 1 and Figure 7 A second limiting component 5 is provided between the lifting platform 6 and the hydraulic main frame 1. The second limiting component 5 includes a limiting sleeve 501 fixedly installed on the lifting platform 6, and the limiting sleeve 501 is internally slidably connected to a limiting rod 502 fixedly installed on the inner side of the hydraulic main frame 1.

[0034] In this embodiment, by setting the limiting sleeve 501 and the limiting rod 502, the lifting platform 6 can be stably limited and supported.

[0035] The working principle and usage process of this utility model are as follows: First, when the cutter head body 4 needs to be installed, the connecting frame 8 can be directly inserted into the positioning sleeve 16. At this time, the pusher head 9 will push the ball 141 outward. The pusher ball 141 drives the telescopic rod 143 and the limiting plate 144 to push outward. The limiting plate 144 pushes the pushed plate 154 and the adjusting plate 152 to rotate, and cooperates with the limiting tooth 153 to lock and fix the adjusting gear 112.

[0036] Next, stabilize the position of the connecting frame 8 and pull out the adjusting plate 152, which drives the limiting plate 144 and the telescopic rod 143 to move and retract. After retraction, rotate the adjusting gear 112, which drives the adjusting rod 111 to rotate. This causes the push frame 113, which is fixedly installed with the adjusting rod 111, to rotate as well. The push frame 113 causes the internal inclined groove to change angle, thereby pushing the pushed rod 114 to move. At this time, with the limiting of the limiting slide groove 132, the movement of the pushed rod 114 is restricted, so that it can be pushed forward at the same time to clamp and fix the snap-fit ​​groove 12 of the connecting frame 8, thereby realizing the installation of the connecting frame 8 and the cutter head body 4. After the installation is completed, the adjusting plate 152 can be loosened, and the adjusting gear 112 can be locked and fixed with the limiting gear 153.

[0037] Finally, when it is necessary to disassemble the connecting frame 8 and the cutter head body 4, the adjusting plate 152 can be pulled directly. The adjustment plate 152 rotates, causing the adjusting plate 152 and the limiting tooth 153 to disengage from the adjusting gear 112. At the same time, it drives the pushed plate 154 to rotate. The pushed plate 154 pushes the limiting plate 144, the telescopic rod 143, and the pushing ball 141 to move inward as a whole. The pushing ball 141 pushes the push head 9, the connecting frame 8, and the cutter head body 4 downward, thereby assisting in the disassembly of the cutter head body 4.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
