Abstract

The utility model discloses a positioning device which comprises a deck board and a positioning board, wherein, an arc groove is arranged on the deck board, a circular arc on which the arc groove is arranged is on the same circumference with the arc groove; the positioning board is correspondingly provided with a circular arc section which cooperates with the arc groove. The positioning device carries out the positioning rotation through arranging the circular arc section on the positioning board, the circular arc section cooperates with the arc groove on the deck board, and the cooperated circular arc surfaces of the circular arc section and the arc groove have higher surface roughness degree, thereby avoiding the condition that the prior positioning device has rocked and inaccurate positioning.

Description

Positioner

Technical field

The utility model relates to the tiltedly positioner of location workpiece under the saw pattern of a kind of compound saw.

Background technology

When compound saw is worked, need the positioner of a location workpiece on the deck plate usually, so that accurately cut under oblique saw pattern.Because the process of industrialization accelerated development of society, workpiece processing more and more needs to save time, efficiently, as much as possible once be installed, finish the multiple tracks production process, so that save unnecessary being installed the time, existing compound saw has tiltedly been designed rotary positioning apparatus under the saw pattern, it is rotated in two grooves of deck plate by two pins that are installed on the location-plate, can play the location, turn to, finish multi-faceted processing, but because gap instability when location-plate rotates of two rotation pins on the location-plate, it is along with the passing of service time, and the rotation pin constantly weares and teares its location, rotation must be affected, the workpiece quality of its processing also must be affected, and also can cause unnecessary waste when serious.

Summary of the invention

The utility model is in view of the defective that exists in the existing location-plate design use, and the spy provides the positioner that a kind of location is more accurate, life cycle is more long.

The technical solution of the utility model comprises: deck plate, location-plate, and deck plate is provided with deep-slotted chip breaker, and the circular arc at deep-slotted chip breaker place is positioned on the same circumference; The corresponding arc section that matches with deep-slotted chip breaker that is provided with of location-plate.Deep-slotted chip breaker minimumly can be one section.

The circumference at the exterior arc surface place of arc section of the present utility model overlaps with the circumference at the exterior arc surface place of deep-slotted chip breaker.The circumference at the inner arc surface place of arc section overlaps with the circumference at the inner arc surface place of deep-slotted chip breaker.

The many disadvantages that the utility model exists in view of existing positioner, on location-plate, establish arc section, deep-slotted chip breaker corresponding on this arc section and the deck plate matches, position rotation, the arc surface that arc section cooperates with deep-slotted chip breaker has higher surface roughness, has stopped existing positioner location and inaccurate situation occurred rocking and locating.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is user mode figure of the present utility model.

The specific embodiment

Referring to accompanying drawing 1-2, the implementation case comprises deck plate 1, location-plate 2, and deck plate 1 is provided with deep-slotted chip breaker 4, and the circular arc at deep-slotted chip breaker 4 places is positioned on the same circumference; The location-plate 2 corresponding arc sections 3 that match with deep-slotted chip breaker 4 on the deck plate 1 that are provided with.Deep-slotted chip breaker 4 minimumly can be one section.When the periphery 31 that relies on arc section 3 was located with the exterior arc surface 41 of deep-slotted chip breaker 4, the circumference at exterior arc surface 31 places of arc section 3 overlapped with the circumference at exterior arc surface 41 places of deep-slotted chip breaker 4.When the inner arc surface 32 that relies on arc section 3 was located with the inner arc surface 42 of deep-slotted chip breaker 4, the circumference at inner arc surface 32 places of arc section 3 overlapped with the circumference at inner arc surface 42 places of deep-slotted chip breaker 4.The arc surface that arc section 3 matches with deep-slotted chip breaker 4 is through accurately machined, has higher surface roughness.Accuracy when so just having guaranteed the workpiece location has reduced friction unnecessary when rotating, and has prolonged the service life of location-plate.

The utility model can be divided into two kinds according to different needs in use: a kind of arc section 3 inner arc surfaces 32 and inner arc surface 42 of deep-slotted chip breaker 4 of relying on located, two arc surfaces become matched in clearance, the radius of the exterior arc surface 31 place circular arcs of arc section 3 is less than the radius of the arc surface 41 place circular arcs of deep-slotted chip breaker 4, arc section 3 migration are in deep-slotted chip breaker 4, and location-plate 2 position rotating are on deck plate 2; Another kind of exterior arc surface 41 location that rely on exterior arc surface 31 with the deep-slotted chip breaker 4 of arc section 3, two arc surfaces become matched in clearance, the radius of the inner arc surface 32 place circular arcs of arc section 3 is greater than the radius of the inner arc surface 42 place circular arcs of deep-slotted chip breaker 4, arc section 3 migration are in deep-slotted chip breaker 4, and location-plate 2 position rotating are on deck plate 2.
