DETAILED DESCRIPTION

[0037] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Example:

[0039] like Figure 1 to Figure 2 As shown, this embodiment discloses a frame-type hydraulic clamp, comprising:

[0040] A mounting platform 10 is provided on the base structure, and a mounting space is provided inside the mounting platform 10. An access window 100 is provided on one side of the mounting platform 10 and is matched with the engine cylinder block 11. The access window 100 is communicated with the mounting space;

[0041] The lifting and clamping assembly 20 is arranged at the bottom of the installation space and is detachably connected to the bottom of the installation platform 10. The lifting and clamping assembly 20 is used to adjust the height of the engine cylinder 11 and the feeding assembly 30;

[0042] A feeding assembly 30, one end of which is disposed on the lifting and clamping assembly 20, and the other end of which extends out of the access window 100, and is used to move the engine cylinder block 11 onto the lifting and clamping assembly 20;

[0043] The positioning clamping assembly 40 is arranged at the top of the installation space and is detachably connected to the top of the installation platform 10. The positioning clamping assembly 40 is located above the lifting clamping assembly 20 and can cooperate with the lifting clamping assembly 20 to fix the engine cylinder block 11;

[0044] Among them, the lifting and clamping assembly 20 includes a main driving hydraulic cylinder 200 and a mounting plate 201. The main driving hydraulic cylinder 200 is arranged in the installation space and is detachably connected to the bottom of the mounting platform 10 by bolts. The mounting plate 201 is arranged on the top of the main driving hydraulic cylinder 200 and is fixedly connected to the top of the main driving hydraulic cylinder 200. The feeding assembly 30 includes a pair of screw feeding structures 300. One end of the pair of screw feeding structures 300 is cooperatively arranged on the mounting plate 201, and the other end extends to the outside of the entrance window 100.

[0045] When the present invention is used, the engine block 11 is first lifted by a crane and placed on one end of the feeding assembly 30 located outside the entry window 100, and then the engine block 11 is moved from outside the entry window 100 to the lifting and clamping assembly 20 by the feeding assembly 30, and is located below the positioning and clamping assembly 40, and finally the feeding assembly 30 and the engine block 11 are raised by the lifting and clamping assembly 20 until the top of the engine block 11 is matched with the positioning and clamping assembly 40, and the fixing of the engine block 11 is completed. Compared with the traditional clamp of the engine block 11, the present invention creatively changes the clamp from side clamping to top and bottom end face clamping. Compared with the side of the engine block 11, the top and bottom end faces of the engine block 11 are usually flat, have higher strength, and are not easily deformed when clamped, so a larger force can be used for clamping, so that the clamping of the engine block 11 is more stable. At the same time, a corresponding feeding structure is provided to facilitate the feeding and clamping of the engine block 11, thereby facilitating the processing of the engine block 11. The problem that the current engine cylinder block 11 clamp is prone to unstable clamping, excessive force on the clamping position, and deformation, which affects the processing quality, is solved. The basic structure includes but is not limited to a flat ground or a mounting platform 10.

[0046] like Figure 6As shown in the figure, as a further preference, guiding telescopic rods 218 are respectively arranged on both sides of the main driving hydraulic cylinder 200. The guiding telescopic rods 218 are arranged in the installation space. One end of the guiding telescopic rod 218 is detachably connected to the bottom of the installation platform 10 through bolts, and the other end is fixedly connected to the bottom of the installation plate 201. The guiding telescopic rod 218 adopts a sliding telescopic rod in the prior art and plays a role in guiding the installation plate.

[0047] As Figure 2 As shown in the figure, since the engine block 11 itself, the installation plate 201 and the feeding assembly 30 have a certain weight, in order to extend the service life of the main driving hydraulic cylinder 200, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that four auxiliary driving hydraulic cylinders 202 are arranged in the installation space. The four auxiliary driving hydraulic cylinders 202 are detachably connected to the bottom of the installation platform 10 through bolts. The output shafts of the four auxiliary driving hydraulic cylinders 202 are arranged in cooperation with the installation plate 201 and can respectively be in contact with the bottom plane of the engine block 11.

[0048] The arrangement of the four auxiliary driving hydraulic cylinders 202 can facilitate sharing the weight of the engine block 11 itself, thereby achieving the effect of extending the service life of the main driving hydraulic cylinder 200. At the same time, when arranging the four auxiliary driving hydraulic cylinders 202, the four auxiliary driving hydraulic cylinders 202 are arranged in cooperation with the bottom plane of the engine block 11, so that the four auxiliary driving hydraulic cylinders 202 can stably support the engine block 11, thereby facilitating preventing the problem that the engine block 11 tilts and falls.

[0049] As Figures 2 to 4 As shown in the figure, in order to facilitate moving the engine block 11, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that the screw feeding structure 300 includes an installation track 301, a rotating screw 302, a driving motor 303 and a supporting threaded block 304. An installation groove 203 is arranged on the installation plate 201 and is arranged in cooperation with the installation track 301. One end of the installation track 301 is fixedly arranged in the installation groove 203. The rotating screw 302 and the supporting threaded block 304 are arranged in the installation track 301 in cooperation. Both ends of the rotating screw 302 respectively penetrate through the installation track 301 and are rotatably connected to the installation track 301. The supporting threaded block 304 is sleeved on the rotating screw 302 and is threadedly connected to the rotating screw 302. The driving motor 303 is arranged at one end of the rotating screw 302, and the output shaft of the driving motor 303 is fixedly connected to the rotating screw 302 for driving the rotating screw 302 to rotate. The engine block 11 can be placed on the supporting threaded block 304.

[0050] When in use, the rotating screw rod 302 can be driven by the driving motor 303, thereby moving the supporting threaded block 304 threadedly connected to the rotating screw rod 302, thereby moving the engine cylinder body 11 placed on the supporting threaded block 304. The use of the rotating screw rod 302 and the supporting threaded block 304 can make the engine cylinder body 11 move at a uniform and stable speed, thereby avoiding the problem of the engine cylinder body 11 falling.

[0051] like Figure 5 As shown, in order to facilitate and better fix the engine cylinder block 11, this embodiment is improved on the basis of the above embodiment, and the difference from the above embodiment is that a limiting plate 305 is provided at the end of the supporting thread block 304 away from the mounting plate 201, and the limiting plate 305 is fixedly set on the top of the supporting thread block 304 and is matched with one side of the engine cylinder block 11, an extension plate 204 is provided on one side of the mounting plate 201, and a fixing plate 205 is provided at the end of the extension plate 204, and a first elastic limiting member 206 and a second elastic limiting member 207 are provided on the fixing plate 205, and the first elastic limiting member 206 and the second elastic limiting member 207 are respectively matched with the other side of the engine cylinder block 11 to limit the engine cylinder block 11.

[0052] like Figure 6 As shown, a pair of limit baffles 216 are also provided on the mounting plate 201, and the pair of limit baffles 216 can respectively contact the two sides of the bottom of the engine cylinder block 11 and are slidably connected. A guide angle 217 is provided on the pair of limit baffles 216, and the guide angle 217 is set at the end of the limit baffle 216 that first contacts the engine cylinder block 11, and is used to guide the engine cylinder block 11.

[0053] When in use, when the engine block 11 moves to the designated position, one side of the bottom of the engine block 11 contacts the first elastic stopper 206 and the second elastic stopper 207, and the first elastic stopper 206 and the second elastic stopper 207 are in the maximum compression state. At this time, the stopper plate 305 limits the other side of the engine block 11, so that the two sides of the bottom of the engine block 11 are fixed. At the same time, when the engine block 11 moves onto the mounting plate 201, a pair of stopper plates 216 can contact the other two sides of the bottom of the engine block 11 respectively, so as to limit the other two sides of the engine block 11.

[0054] like Figures 7 and 8As shown, in order to facilitate the first elastic limit member 206 and the second elastic limit member 207 to reset after compression, the first elastic limit member 206 includes a first silicone contact head 208, a first slide bar 209, a first spring 210 and a first limit plate 211. One end of the first slide bar 209 passes through the fixed plate 205 and is slidably connected to the fixed plate 205. The first silicone contact head 208 is fixedly arranged at the end of the first slide bar 209 that contacts the engine cylinder body 11. The first limit plate 211 is fixedly arranged at the other end of the first slide bar 209. The first spring 210 is arranged between the fixed plate 205 and the first limit plate 211, and the two ends are respectively fixedly connected to the fixed plate 205 and the first limit plate 211.

[0055] The second elastic limiting member 207 includes a second silicone contact head 212, a second sliding rod 213, a second spring 214 and a second limiting plate 215. One end of the second sliding rod 213 passes through the fixed plate 205 and is slidably connected to the fixed plate 205. The second silicone contact head 212 is fixedly arranged at the end of the second sliding rod 213 that contacts the engine cylinder body 11. The engine cylinder body 11 has a protrusion 101 that is arranged to cooperate with the second silicone contact head 212. The second silicone contact head 212 can contact the protrusion 101. The second limiting plate 215 is fixedly arranged at the other end of the second sliding rod 213. The second spring 214 is arranged between the fixed plate 205 and the second limiting plate 215, and the two ends are respectively fixedly connected to the fixed plate 205 and the second limiting plate 215.

[0056] The first spring 210 and the second spring 214 are provided to facilitate the first elastic stopper 206 and the second elastic stopper 207 to reset after being compressed. When the engine cylinder 11 compresses the first elastic stopper 206 and the second elastic stopper 207, the first slide bar 209 and the second slide bar 213 slide, and the spring is stretched; when the engine cylinder 11 does not compress the first elastic stopper 206 and the second elastic stopper 207, the spring resets, thereby driving the first slide bar 209 and the second slide bar 213 to slide and reset.

[0057] like Figure 3 As shown in Figure 5, in order to facilitate the installation of the driving motor 303, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that the driving motor 303 in a pair of screw feeding structures 300 is fixedly connected to one side of the fixed plate 205 through a connecting structure 306. The connecting structure 306 includes a pair of fixed connecting plates 307. The pair of fixed connecting plates 307 are arranged on one side of the fixed plate 205 and are detachably connected to the fixed plate 205 by bolts. The driving motors 303 in a pair of screw feeding structures 300 can be fixedly installed on a pair of fixed connecting plates 307 respectively.

[0058] like Figure 2As shown, in order to facilitate the positioning and clamping assembly 40 to clamp the top of the engine cylinder block 11, this embodiment is improved on the basis of the above embodiment, and the difference from the above embodiment is that the positioning and clamping assembly 40 includes a pair of mounting frames 400, and the pair of mounting frames 400 are arranged in the installation space, and one end of the pair of mounting frames 400 are respectively detachably connected to the top of the mounting platform 10 by bolts, and each mounting frame 400 is provided with a pair of spring limit pins 401, and one end of the pair of spring limit pins 401 is fixedly connected to the mounting frame 400, and the other end can contact with the top plane of the engine cylinder block 11, and each mounting frame 400 is also provided with a plurality of pads 402 that can contact with the top plane of the engine cylinder block 11.

[0059] The cushion block 402 can be an air cushion block 402 in the prior art, and the spring stop pin 401 can be a spring stop pin 401 in the prior art. When in use, the arrangement of the spring stop pin and the cushion block 402 can effectively limit the top plane of the engine cylinder block 11, thereby cooperating with the lifting clamping assembly 20 to fix the engine cylinder block 11.

[0060] like Figure 2 As shown, in order to facilitate the support of the end of the feeding assembly 30 outside the entrance window 100, the present embodiment is improved on the basis of the above embodiment, and the difference from the above embodiment is that the mounting platform 10 is provided with an expansion plate 102 at the bottom of one side of the entrance window 100, and one side of the expansion plate 102 is fixedly connected to the mounting platform 10, and a support frame 103 is provided on the expansion plate 102, and the bottom of the support frame 103 is detachably connected to the expansion plate 102 by bolts, and the top of the support frame 103 can contact with the bottom of a pair of screw feeding structures 300 located at one end outside the entrance window 100, and is used to support a pair of screw feeding structures 300, and a reinforcement frame 104 is provided on one side of the support frame 103, and one side of the reinforcement frame 104 is fixedly connected to the support frame 103, and the other end can contact with the bottom of a pair of screw feeding structures 300.

[0061] The arrangement of the support frame 103 and the reinforcement frame 104 can effectively support the end of the feeding assembly 30 located outside the entry window 100. The support frame 103 and the reinforcement frame 104 are connected to the feeding assembly 30 in a contacting but not fixed manner, so that when the lifting clamping assembly 20 drives the feeding assembly 30 to rise and fall, the support frame 103 and the reinforcement frame 104 can be easily contacted or separated from the feeding assembly 30.

[0062] like Figure 3As shown, for the convenience of installation, this embodiment is improved on the basis of the above embodiment, and the difference from the above embodiment is that the mounting platform 10 includes a bottom platform 105, a top platform 106 and a pair of connecting side panels 107, the bottom platform 105 is arranged on the basic structure and fixedly connected to the basic structure, the pair of connecting side panels 107 are arranged on the bottom platform 105, the top platform 106 is arranged on the pair of connecting side panels 107, the two ends of the pair of connecting side panels 107 are respectively fixedly connected to the top platform 106 and the bottom platform 105, the mounting space is arranged between the pair of connecting side panels 107, the entrance window 100 is arranged between the pair of connecting side panels 107 and is located at one end of the pair of connecting side panels 107, a first window 108 is arranged between the pair of connecting side panels 107, the first window 108 is arranged between the pair of connecting side panels 107 and is located at the other end of the pair of connecting side panels 107, and a second window 109 is provided on each of the pair of connecting side panels 107.

[0063] The mounting platform 10 adopts a split structure, which can be easily installed during the initial installation.

[0067] In order to facilitate lifting the top platform 106 during installation, a plurality of lifting rings 113 are provided on the top of the top platform 106 , and the plurality of lifting rings 113 are fixedly connected to the top of the top platform 106 .

[0068] like Figure 1 As shown, a method for using a frame-type hydraulic clamp is applied to the frame-type hydraulic clamp described above, comprising the following steps:

[0069] Step 1: Lift the engine block 11 and place it on one end of the feeding assembly 30 outside the access window 100;

[0070] Step 2: The engine block 11 is moved from the outside of the access window 100 to the lifting and clamping assembly 20 through the feeding assembly 30 and is located below the positioning and clamping assembly 40;

[0071] Step 3: The feeding assembly 30 and the engine block 11 are raised by lifting the clamping assembly 20 until the top of the engine block 11 is matched with the positioning clamping assembly 40 to complete the fixing of the engine block 11.

[0072] Preferably, step 1 is specifically:

[0073] Adjust the supporting thread block 304 in the pair of screw feeding structures 300 so that it is located outside the access window 100, lift the engine block 11, and place it on the supporting thread block 304 in the pair of screw feeding structures 300;

[0074] Preferably, step 2 is specifically:

[0075] The supporting threaded blocks 304 in the pair of screw feeding structures 300 are adjusted to move the engine cylinder 11 from the outside of the access window 100 to above the mounting plate 201 in the lifting clamping assembly 20, and at the same time, the engine cylinder 11 forms a matching limit with the limit plate 305, the first elastic limit member 206, the second elastic limit member 207 and the pair of limit baffles 216, and is located below the positioning clamping assembly 40;

[0076] Preferably, step 3 is specifically:

[0077] The feeding assembly 30 and the engine block 11 are raised by the main driving hydraulic cylinder 200 and four auxiliary driving hydraulic cylinders 202 until the top of the engine block 11 cooperates with the elastic limit pin and the cushion block 402 in the positioning clamping assembly 40 to complete the fixing of the engine block 11.

[0078] By using the method of the present invention, the engine cylinder block 11 can be quickly fixed.

[0079] Working principle of the present invention:

[0080] When the present invention is used, the engine block 11 is first lifted by a crane and placed on the end of the feeding assembly 30 outside the entry window 100, and then the engine block 11 is moved from outside the entry window 100 to the lifting and clamping assembly 20 by the feeding assembly 30, and is located below the positioning and clamping assembly 40, and finally the feeding assembly 30 and the engine block 11 are raised by the lifting and clamping assembly 20 until the top of the engine block 11 is matched with the positioning and clamping assembly 40, thereby completing the fixing of the engine block 11. Compared with the traditional clamp of the engine block 11, the present invention creatively changes the clamp from side clamping to top and bottom end face clamping. Compared with the side of the engine block 11, the top and bottom end faces of the engine block 11 are usually flat, have higher strength, and are not easily deformed when clamped, so a larger force can be used for clamping, making the clamping of the engine block 11 more stable. At the same time, a corresponding feeding structure is provided to facilitate the loading and clamping of the engine cylinder block 11 , thereby facilitating the processing of the engine cylinder block 11 .

[0081] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
