Abstract
The utility model discloses an auxiliary mounting part for splicing high-precision gear racks conveniently. The auxiliary mounting part is a gear rack section which is the same as the to-be-mounted gear racks in module and pressure angle and opposite to the to-be-mounted gear racks in tooth spiral direction. The auxiliary mounting part adopts the mounting method that (1) a first to-be-mounted gear rack and a second to-be-mounted gear rack are clung to each other tightly during mounting, and the bottoms of the gear racks lean against to-be-mounted equipment; (2) the auxiliary mounting part is buckled to the seam of the two gear racks in an inverted manner, and the teeth of the auxiliary mounting part are uniformly distributed to the gear racks; and (3), the gear racks are clamped with the auxiliary mounting part and one surface of the to-be-mounted equipment through two clamping grippers, and the seam between the gear racks during mounting can be kept with an optimal distance through clamping force and the continuous toothed surface of the auxiliary mounting part. The auxiliary mounting part has the advantages that the mounting is convenient; a batch of gear racks with the same module can be mounted with the same mounting block; the machining precision requirement on an end is low during processing; the processing cost is reduced; and the transmission precision is guaranteed.
Description
Technical field
The utility model relates to general tooth bar field, especially relates to a kind of auxiliary installation piece that makes things convenient for the tooth bar continued access.
Background technology
Method at present commonly used be with the tooth bar end through the higher processing of row ratio of precision, guarantee that the tooth pitch of the increment of its joint is a standard value when mounted, i.e. π m (m is the tooth bar modulus).
The prior art shortcoming mainly is to have man-hour than higher requirement adding, and the designated precision that must reach design can guarantee the accurate transmission agency of tooth bar, and it manufactures comparatively trouble, and the machining accuracy of lathe is had very big dependence.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art; A kind of auxiliary installation piece that makes things convenient for continued access high accuracy tooth bar is provided; It can reduce processing request; But can conveniently install and can guarantee the termination tooth pitch realization continued access tooth bar precision drive of standard during installation, an auxiliary installation piece can have the installation that is directed against a collection of with the isostructural tooth bar of modulus simultaneously.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of auxiliary installation piece that makes things convenient for continued access high accuracy tooth bar, it is and the rack segments that tooth bar modulus, pressure angle are identical, the tooth hand of spiral is opposite to be installed.
Said rack segments has 14-18 tooth.
Said rack segments has 16 teeth.
The above-mentioned preparation method that makes things convenient for the auxiliary installation piece of continued access high accuracy tooth bar, straight-tooth auxiliary installation piece use modulus, the tooth bar intercepting rack segments that pressure angle is identical get final product; The helical teeth auxiliary installation piece need process one opposite with the rack tooth hand of spiral to be installed, modulus, tooth bar and intercepting rack segments that pressure angle is identical get final product.
A kind of installation method that makes things convenient for continued access high accuracy tooth bar is characterized in that,
At first first tooth bar to be installed and second tooth bar to be installed closely are close together when (1) installing, the bottom of two tooth bars comes on the equipment to be installed;
(2) with the seam crossing of above-mentioned installation auxiliary member left-hand thread to two tooth bar to be installed, its tooth is evenly distributed to two tooth bars;
(3) use the clamping pliers that two tooth bars to be installed are clamped with auxiliary member and device side to be installed are installed, rely on the continuous flank of tooth of clamping force and installation auxiliary member just can make the tooth bar seam when installing remain to optimum distance.
Described tooth bar is spur rack or diagonal-cut rack.
The detailed design main points:
1. the straight-tooth auxiliary installation piece is identical with former rack structure;
2. the helical teeth auxiliary installation piece hand of spiral and former tooth bar are in the opposite direction, and every heel teeth bar is uniformly distributed with about 8 teeth during installation.
The beneficial effect of the utility model is: the convenient installation, and a mounting blocks can be installed a collection of tooth bar with modulus, and the machining accuracy that adds the end in man-hour needn't require so high, cuts down finished cost, and guarantees transmission accuracy.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment 1 spur rack is installed auxiliary member
Please refer to Fig. 1, Fig. 2, Fig. 6 for spur rack, can adopt existing same modulus, isostructure, spur rack that pressure angle is identical in the making, use sawing machine that it is cut to the rack segments with 16 teeth, remove the end face burr, and the chamfered edge limit.Reference shape Fig. 23 D stereo line chart after the intercepting, the flank profil direction can be referring to Fig. 6, and as can be seen from the figure its spur rack 10 is consistent with the teeth directional of straight-tooth installation auxiliary member 3.
At first left side spur rack 1 to be installed closely is close together with right spur rack 2 to be installed during installation, the tooth bar bottom comes on the equipment to be installed, and straight-tooth is installed the seam crossing of auxiliary member 3 left-hand threads to two toothed rack, and the equal cloud of its tooth is distributed to two tooth bars.Use and clamp pliers Figure 1A face and device side to be installed clamping; Same another clamping pliers that uses clamps Figure 1B and device side to be installed, and the continuous flank of tooth that relies on clamping force and straight-tooth that auxiliary member 3 is installed just can make the spur rack seam 4 when installing remain to optimum distance.
Embodiment 2 diagonal-cut racks are installed auxiliary member
Please refer to Fig. 3, Fig. 4, Fig. 5 for diagonal-cut rack; Be respectively left diagonal-cut rack to be installed 5; Right diagonal-cut rack 6 to be installed, helical teeth is installed auxiliary member 7 and diagonal-cut rack seam 8, and its installation method and spur rack are similar to repeat no more here; About its planform is distinguishing; As can be seen from Figure 5 helical teeth installation auxiliary member 7 is just in time opposite with the hand of spiral of diagonal-cut rack 9 teeth, needs necessary opposite tooth bar of still its tooth hand of spiral that has identical modulus and structure thereof with the installation tooth bar of cutting during making, and the tooth bar of intercepting part then gets final product.
, guarantee that joint has correct connection tooth pitch, makes transmission more accurate through top tooth bar being made and but technological improvement greatly reduces the precision of processing continued access tooth bar termination.
