Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a machining device for holes at special positions. Background Technique

[0002] Taking the machining of the explosion pressure hole on the cylinder head as an example, since the machined hole cannot damage the relevant air passages and the original cylinder holes on the original cylinder head, the designer arranges the position of the explosion pressure hole in a relatively special way. This hole is neither perpendicular nor parallel to the six end faces of the original cylinder head itself, which causes difficulties in machining. The position of the above explosion pressure hole on the cylinder head is as follows: taking the upper side of the front view of the cylinder head workpiece as the bottom surface, facing the direction of the machine tool spindle frontally, rotating counterclockwise by 27.87°, and then adjusting the upward tilt by 31.69°.

[0003] In the process of machining the explosion pressure hole on the cylinder head, the hole system machining of this part is preferably arranged on a numerical control device with four or more axes, and the machining spindle of the machine tool needs to be rotated by an appropriate angle to be machined. However, considering that the use of a four-axis machining center has a high processing cost (the machining center is a high-precision and valuable device), and the machine-hour and delivery time are also not in time. Therefore, a machining device for holes at special positions is proposed to solve the above problems. Content of the Utility Model

[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0024] A special-position hole machining device includes a universal rotating disk 1 on the boring machine worktable surface and a clamping device 2. The clamping device 2 is arranged on the top of the disk surface of the universal rotating disk 1. The clamping device 2 includes a slide rail block 201, an assembly rod 202, a first screw 203, a pressing plate 204, a slot 205, a hexagonal nut 206, a second stud 207, a plug rod 208, a housing 209, a first clamping plate 210, a sleeve 211, a second clamping plate 212, a column rod 213, a spring 214, a vertical rod 215, a ring block 216, a top cover plate 217, a rubber suction cup 218 and a bottom cover plate 219. The slide rail block 201 is slidably arranged in the internal guide groove of the disk surface of the universal rotating disk 1. The top of the slide rail block 201 is provided with an assembly rod 202. The bottom end of the assembly rod 202 is fixedly provided with a first screw 203. The bottom rod of the assembly rod 202 is in fitting contact with the slot 205 opened in the pressing plate 204. The bottom end of the pressing plate 204 is in fitting contact with a hexagonal nut 206. The internal part of the hexagonal nut 206, the internal part of the bottom end of the pressing plate 204 and the second stud 207 are threadedly assembled. The bottom end of the second stud 207 is fixedly provided with a plug rod 208. The plug rod 208 is slidably arranged in the internal part of the top end of the housing 209. The inner wall of the housing 209 is fixedly provided with a first clamping plate 210. The bottom end of the first clamping plate 210 is fixedly provided with a sleeve 211. The bottom of the first clamping plate 210 is provided with a second clamping plate 212. The top end of the second clamping plate 212 is fixedly provided with a column rod 213. A spring 214 is fixedly arranged between the first clamping plate 210 and the second clamping plate 212. The bottom end of the plug rod 208 is fixedly provided with a vertical rod 215. The outer side of the vertical rod 215 is fixedly provided with a ring block 216. The bottom end of the vertical rod 215 is fixedly provided with a top cover plate 217. The inner wall of the bottom end of the housing 209 is fixedly provided with the rubber suction cup 218 around the outer side. The top end of the rubber suction cup 218 is fixedly provided with a bottom cover plate 219.

[0025] The first screw 203 is threadedly assembled with the internal thread hole opened in the top end of the slide rail block 201. The first screw 203 is vertically fixedly arranged with the pressing plate 204. Through the above settings, it is convenient to perform fitting and limiting on the top end face of the cylinder head.

[0026] The spring 214 is spirally distributed on the outer side of the sleeve 211 and the outer side of the column rod 213. The column rod 213 is slidably arranged on the inner wall of the sleeve 211. Through the above settings, it is convenient to perform elastic reset on the column rod 213, the spring 214 and the vertical rod 215.

[0027] The bottom end of the ring block 216 is in fitting contact with the top end of the second clamping plate 212. The outer side of the vertical rod 215 is slidably arranged with the second clamping plate 212. The top end of the bottom cover plate 219 is in fitting contact with the bottom end of the top cover plate 217. Through the above settings, through the fitting state of the bottom cover plate 219 and the top cover plate 217, and in cooperation with the vertical extrusion of the top cover plate 217 by the vertical rod 215, the extrusion and exhaust of the rubber suction cup 218 are realized.

[0028] The first screw rod 203 is arranged in parallel with the insertion rod 208 and the vertical rod 215. The bottom end of the housing 209 and the bottom end of the rubber suction cup 218 are in close contact with the top of the disk surface of the universal rotary disk 1. Through the above settings, a relatively stable vertical interactive adsorption and limiting structure is formed.

[0029] Working process: The present utility model provides a horizontal boring machine processing device for the explosion pressure holes at special positions of the cylinder head, which plays a role in adjusting the angle of the cylinder head and achieving an excellent clamping and limiting effect, and is beneficial to the stability during the boring machine drilling process.

[0030] When the device is in use, the universal rotary disk 1 is hoisted and placed on the boring machine workbench through the internal crane in the workshop. Subsequently, the cylinder head is hoisted and placed on the top of the disk surface of the universal rotary disk 1 again through the internal crane in the workshop. Using the universal rotary disk 1, rotate the angles in two directions, slide the slide rail block 201 into the internal guide groove on the disk surface of the universal rotary disk 1, place the pressing plate 204 in contact with the top inclined surface of the cylinder head. The assembly rod 202 and the first screw rod 203 are of an integral structure. The bottom rod of the assembly rod 202 fits with the slot 205. Manually rotate the assembly rod 202 so that the first screw rod 203 rotates threadedly with the internal threaded hole opened at the top end of the slide rail block 201 until the assembly rod 202 presses against the top end of the pressing plate 204. Since the pressing plate 204, the hexagon nut 206, the second stud 207, the insertion rod 208, the vertical rod 215, the ring block 216 and the top cover plate 217 are of an integral rod, during the vertical threaded assembly of the first screw rod 203 and the slide rail block 201, the top cover plate 217 squeezes the bottom cover plate 219, causing the air inside the rubber suction cup 218 to be discharged. At this time, manually press the bottom end of the housing 209 and the bottom end of the rubber suction cup 218 against the top of the disk surface of the universal rotary disk 1 to form an auxiliary adsorption and limiting effect, thereby forming a stable clamping structure.

[0031] The first clamping plate 210, the sleeve 211, the second clamping plate 212, the column rod 213 and the spring 214 form an elastic reset structure. When the assembly rod 202 is manually rotated in the reverse direction, manually lift the state where the bottom end of the rubber suction cup 218 is in close contact with the top of the disk surface of the universal rotary disk 1, and the stretched spring 214 automatically resets. Through the contact state between the second clamping plate 212 and the ring block 216, the rubber suction cup 218 can be reset.

[0032] This solution provides a simple and low-cost processing device. By projecting and decomposing the hole system angle of the cylinder head and then calculating, the required angle value during processing is obtained. Use the universal rotary disk 1 to rotate the angles in two directions, and then place it on an ordinary horizontal boring machine for processing. Clamp and assemble the cylinder head on the disk surface of the universal rotary disk 1, and then boring machine processing and drilling can be carried out after clamping.

[0033] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
