Embodiment 1

Please refer to Fig. 1-5, a kind of indexable tup for single block hammer crusher, including hammer handle 1, hammer body 2, positioning spiral shell Bolt 3 and unloading bolt 4；The hammer handle 1 is equipped with hammer handle inclined-plane 11 and disassembly threaded hole 12；The hammer handle inclined-plane 11 is located at hammer handle It is 175 ° with perpendicular angle on hammer handle 1 at 1 lower end two sides；The disassembly threaded hole 12 is located at 1 lower end surface centre bit of hammer handle It sets, and dismantles and be equipped with conical socket at threaded hole 12；

The hammer body 2 is U-shaped structure, and hammer body 2 is equipped with hammer body inclined-plane 21 and counter sink 22；The hammer body inclined-plane 21 is set In the inside at 2 both ends of hammer body, and hammer body inclined-plane 21 and 2 upper surface angle of hammer body are 85 °；The counter sink 22 is located under hammer body 2 End face center position, and counter sink 22 is the through-hole being internally threaded；

Further, in order to be mounted on tup on crusher, mounting hole is additionally provided at the top of hammer handle 1；

The positioning bolt 3 cooperates with counter sink 22, and the major diameter numerical value of positioning bolt 3 is greater than the interior of disassembly threaded hole 12 Diameter numerical value；

The demounting bolt 4 cooperates with disassembly threaded hole 12, and the major diameter numerical value of demounting bolt 4 is less than spiral shell in counter sink 22 The numerical value of line internal diameter；

Preferably, the hammer handle 1 and 2 material of hammer body are abrasion-resistant stee.

The working principle of the present embodiment is:

Installation process: hammer handle 1 is mounted in hammer body 2, cooperates hammer handle inclined-plane 11 and hammer body inclined-plane 21, by positioning bolt 3 are mounted in the counter sink 22 of hammer body 2, and rotational positioning bolt 3 makes it be pressed in the conical socket for dismantling threaded hole 12 on hammer handle 1 On, continue rotational positioning bolt 3, provides pretightning force for hammer handle inclined-plane 11 and hammer body inclined-plane 21, realize self-locking, it is ensured that worked The stabilization of hammer body in journey.

Disassembly process: removing positioning bolt 3 first, loads onto unloading bolt 4, the disassembly screw thread on unloading bolt 4 and hammer handle 1 The cooperation of hole 12, rotation unloading bolt 4 are pressed in it on hammer body 2, continue rotation unloading bolt 4 removal hammer handle inclined-plane 11 and hammer body is oblique Pretightning force between face 21 keeps it no longer self-locking, and unloading bolt 4 is backed out in reverse rotation, and hammer body 2 is removed from hammer handle 1.

The course of work: crusher is that hammer body 2 unilateral abrasion occurs in work, needs to carry out indexing to hammer body 2 at this time；It is first Above-mentioned disassembly process is first carried out, then push top 2 is rotated 180 ° on being installed to hammer handle 1, at this time the mill of hammer body 2 by disassembly push top 2 It damages side and non-wear-side is exchanged.

It replaces hammer body: when two lateral wearing of hammer body, executing above-mentioned disassembly process, dismantle hammer body 2, then execute and installed Journey installs a new hammer body 2.
