Description

Angle detecting device before the hobboing cutter

Technical field

The utility model relates to the preceding angle detecting device of a kind of hobboing cutter.

Background technology

Gear, spline generally adopt hobboing cutter processing, and no matter the hobboing cutter anterior angle is positive rake angle or negative rake, and the point of a knife of rake face is all crossed center cutter; Tool orthogonal rake α value, in use, hobboing cutter can wear and tear; Need reface to preceding cutter, make anterior angle reach standard value.Therefore, in the process of refacing, to measure hobboing cutter anterior angle value.The price of standard detection instrument is high in the market.

Summary of the invention

The technical matters that the utility model will solve is: provide a kind of hobboing cutter preceding angle detecting device, make its energy measurement hobboing cutter anterior angle value and cost lower.

In order to solve the problems of the technologies described above, the utility model comprises beat appearance, mandrel and measuring appliance, and the beat appearance comprises base, be slidingly arranged in the pallet on the base and be fixed on the base and to be positioned at two of pallet top top; Mandrel is that two ends have top locating slot, the reeded axle in middle part; The groove bottom of the groove of mandrel is that measuring appliance comprises support, shifter lever and clock gauge through the plane of the axis of mandrel, and shifter lever is the L shaped body of rod; The middle corners place and the support of shifter lever are rotationally connected; Clock gauge is fixed on the support, and the gauge head of clock gauge withstands on the lateral surface of shifter lever one end, and the support of measuring appliance is fixed on the pallet of beat appearance.

For the ease of regulating the height of shifter lever, described shifter lever rotates through bearing pin and is arranged on the support, and the hole that bearing pin is installed on the support is the strip hole of length direction in the vertical direction, and bearing pin is provided with locking device.

The beneficial effect of the utility model is: the utility model is converted into the reading of clock gauge with the variation of hobboing cutter angle, thereby calculates the anterior angle angle through shifter lever, and adjusting for refacing of hobboing cutter provides reliable foundation, has guaranteed the precision of refacing of hobboing cutter.The utility model is simple in structure, and cost is low, compares with purchase standard detection instrument to have tangible price advantage, and is economical and practical.

Embodiment

A kind of specific embodiment as shown in Figure 1; It comprises beat appearance 1, mandrel 2 and measuring appliance 3; Beat appearance 1 comprises base 1-1, is slidingly arranged in the pallet 1-2 on the base 1-1 and is fixed on two top 1-3 that base 1-1 went up and be positioned at pallet 1-2 top; Mandrel 2 is top locating slot, the reeded axle in middle part for two ends have, and the groove bottom of the groove of mandrel 2 is the plane through the axis of mandrel.

As shown in Figures 2 and 3; Measuring appliance 3 comprises support 3-1, shifter lever 3-4 and clock gauge 3-5, and shifter lever 3-4 is the L shaped body of rod, and the lateral surface at the two ends of shifter lever 3-4 is perpendicular; The two ends length of shifter lever 3-4 is identical; Middle corners place and the support 3-1 of shifter lever 3-4 are rotationally connected, and clock gauge 3-5 is fixed on the support 3-1, and the gauge head of clock gauge 3-5 withstands on the lateral surface of shifter lever 3-4 one end; The other end of shifter lever 3-4 is the test side, and the support 3-1 of measuring appliance 3 is fixed on the pallet 1-2 of beat appearance 1.

Shifter lever 3-4 rotates through bearing pin 3-3 and is arranged on the support 3-1, and it is the strip hole 3-2 of length direction in the vertical direction that support 3-1 goes up the hole that bearing pin 3-3 is installed, and the end of bearing pin 3-3 is provided with nut, and the other end of bearing pin 3-3 is connected with nut.

Principle of work:

At first be installed on the beat appearance 1 mandrel 2 as shown in Figure 1 during detection; Regulate the position of bearing pin 3-3; Make the center of the logical top 1-3 in test side of shifter lever 3-4, top 1-3 move forward and backward pallet 1-2 in the radial direction, with the bottom surface adjustment level of mandrel 2 upper grooves; This position is decided to be zero point, and 3-5 is adjusted to zero-bit with clock gauge.

Mandrel 2 is removed, loaded onto hobboing cutter 4, as shown in Figure 3; Test side with the nose part bit alignment shifter lever 3-4 of the rake face of hobboing cutter 4; And rotate hobboing cutter 4 and make clock gauge 3-5 to zero, traverse measurement device 3 is read the variable quantity △ r of clock gauge relative zero this moment at the certain distance X that moves ahead in the radial direction of top 1-3; Utilize function calculation to go out anterior angle α value, i.e. tg α=△ r/X.

This pick-up unit is particularly suitable in hobboing cutter is refaced process, detecting the hobboing cutter anterior angle.
