Detailed Description
Referring to fig. 2A to 4, the present invention is a grinding machine with a movable fixing base 30, comprising:
a body 20; in this embodiment, the main body 20 has a base 21 and a polishing portion 22, the polishing portion 22 is disposed on the base 21, and a polishing wheel for polishing is disposed in the polishing portion 22;
a fixing seat 30 fixed on the body 20, wherein the fixing seat 30 has a chuck hole 31 and a clamping rod 32 pivoted on the fixing seat 30; in this embodiment, the fixing base 30 has a bottom portion 33 and an operation portion 34 connected to each other, the bottom portion 33 is fixed on the base portion 21, the operation portion 34 is connected to the polishing portion 22, and the chuck hole 31 penetrates through the operation portion 34 and is connected to the polishing portion 22;
a rotating chuck 40 having a rotating portion 41 and an adjusting portion 42, the rotating chuck 40 having a working hole 43 passing through the rotating portion 41 to the adjusting portion 42, the rotating portion 41 being pivotally disposed in the chuck hole 31, the adjusting portion 42 having at least two adjusting holes 421, the at least two adjusting holes 421 being for being fastened to or separated from the fastening rod 32.
In this embodiment, the chuck hole 31 is a circular hole, and the rotating portion 41 is a circular tube, so that the rotating portion 41 can pivot along the circumferential direction of the rotating portion 41 when the rotating portion 41 is pivoted in the chuck hole 31.
Next, the adjusting portion 42 is provided with a surrounding wall 422 protruding from an end of the rotating portion 41 away from the grinding portion 22, and a plurality of adjusting holes 421 are recessed from a periphery of the surrounding wall 422, wherein a distance between the adjusting holes 421 is set according to positions of different blades on different tools.
Furthermore, the fixed seat 30 has an abutting surface 341 facing the rotating chuck 40, the abutting surface 341 is protruded with two pivot blocks 35, and the locking rod 32 is pivoted between the two pivot blocks 35, so that the locking rod 32 can pivot around the position pivoted with the two pivot blocks 35.
Specifically, the adjusting portion 42 is provided with a protruding abutting rib 44, the abutting rib 44 surrounds the chuck hole 31, and when the rotating chuck 40 is assembled on the fixing base 30, the surrounding wall 422 abuts against the abutting rib 44, so that the rotating chuck 40 can rotate more smoothly.
In view of the above, the present invention provides a structure configuration and connection relationship thereof in a preferred embodiment, the usage and the effect thereof can be achieved as follows:
since the locking lever 32 can pivot, the relative relationship between the locking lever 32 and the rotating chuck 40 has a locking state Q1 and a releasing state Q2:
referring to fig. 4, in the locking state Q1, the locking rod 32 is locked in one of the adjusting holes 421, so that the rotating chuck 40 cannot rotate in the circumferential direction, and at this time, the user can first grind the blade corresponding to the position of the locked adjusting hole 421.
Referring to fig. 5 to 8, when a user wants to rotate the rotating chuck 40, the user can pivot the locking lever 32 first to switch from the locking state Q1 to the releasing state Q2, so that the locking lever 32 is disengaged from the adjusting hole 421, and the rotating chuck 40 can rotate along the circumferential direction, and when the rotating chuck 40 rotates to make the next adjusting hole 421 correspond to the locking lever 32, the user can pivot the locking lever 32 again to lock the locking lever 32 to the corresponding adjusting hole 421, so as to switch from the releasing state Q2 to the locking state Q1.
Therefore, when the user grinds the cutting edge on the cutter, the rotary chuck 40 can be rotated to change the cutting edge to be ground correspondingly without pulling the cutter out of the chuck hole 31, thereby not only saving the operation time but also making the grinding operation more smooth.
Specifically, referring to fig. 2B and 3, a concave hole 342 is further concavely formed on the abutting surface 341, an internal thread is formed in the concave hole 342, the concave hole 342 is used for locking a safety bolt 50, and an external thread is formed on the safety bolt 50, so that the external thread on the safety bolt 50 can be screwed with the internal thread in the concave hole 342, and the safety bolt 50 abuts against one end surface 441 of the abutting rib 44, thereby positioning the rotating chuck 40 to prevent the rotating chuck from rotating.
Since the common cutter is fixed on the cutter chuck, it can be directly fixed in the working hole 43 for grinding, and since the four edges of the common cutter are perpendicular to each other and cross-shaped when viewed from the end surface, different edges on the same cutter can be ground, only the cutter chuck fixed with the cutter needs to be rotated and abutted against the two fixing posts 423 convexly arranged on the surrounding wall 422, therefore, in the normal state of grinding the common cutter, the safety bolt 50 is fixed on the concave hole 342 and protrudes, so that the safety bolt 50 abuts against the end surface 441 of the abutting rib 44, not only the rotating chuck 40 can be fixed by the clamping rod 32, but also the rotating chuck 40 can be positioned by the safety bolt 50 to prevent the rotating chuck from rotating or shaking.
Referring to fig. 6 to 8, when grinding a special type of tool, since the four edges of the special type of tool have obtuse and acute angles when viewed from the end surface, the tool on the tool holder is fixed in the working hole 43, and the rotating holder 40 needs to be rotated to allow the edges with different angles to be ground correctly; since the safety pin 50 abuts against the end surface 441 of the abutting rib in a normal state, and the safety pin 50 corresponds to the surrounding wall 422 and cannot be locked, the locking rod 32 must be separated from the adjusting hole 421 to allow the rotating chuck 40 to rotate in one circumferential direction, so that one of the adjusting holes 421 is aligned with the safety pin 50, and at this time, a hand tool 91 is used to pass through the adjusting hole 421 to release the safety pin 50, so as to separate the safety pin 50 from the concave hole 342, and allow the rotating chuck 40 to rotate freely in the chuck hole 31.
By the cooperation of the safety pin 50 and the concave hole 342, when grinding a general cutter, the safety pin 50 can stabilize the rotating chuck 40 so as not to rotate and shake, and when grinding a cutter of a special type, the safety pin 50 can be released so as to enable the rotating chuck 40 to rotate freely in the chuck hole 31, so that the clamping rod 32 is matched with the other adjusting hole 421, and the cutting edge of the cutter of the special type can be abutted against the grinding wheel correctly.
