Abstract
The utility model discloses a guide head for an inserting tube of a heat exchanger, comprising a guide head (1), an expansion sleeve (2) and a conical mandrel (3). The guide head is characterized in that threads are formed in the guide head (1); the conical mandrel (3) is connected with the guide head (1) through the threads; the expansion sleeve (2) is sleeved on the conical mandrel (3); one end of the expansion sleeve (2) is in contact with the guide head (1); and the other end of the expansion sleeve (2) is in contact with the conical mandrel (3). The utility model has favorable self-lock performance, is not easy to separate from heat exchange tubes and obtains the favorable effect.
Description
Technical field
The utility model relates to a kind of assembling accessory.
Background technology
At present, when heat exchanger tube was made, heat exchanger tube needed carry out the blind operation of wearing by tube sheet, deflection plate, tube sheet, because between the deflection plate, between deflection plate and the tube sheet certain spacing is arranged all, therefore need target seeker to lead, with after the heat exchanger tube correcting smoothly by deflection plate and tube sheet.Owing to be blind wearing, require target seeker when the poling operation, can not separate, otherwise target seeker will drop in the housing and can't take out, thereby influence the normal use of equipment with heat exchanger tube.There is error because heat exchanger tube assembles between length, the deflection plate, causes the pore decentraction on the deflection plate, so just need be when the poling operation by means of the sledgehammer poling, owing to be subjected to the vibrations of sledgehammer, target seeker very easily breaks away from heat exchanger tube.The design of self-locking target seeker preferably resolves this problem.
The utility model content
The utility model purpose provide a kind of can be with the target seeker of auto-lock function
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of heat exchanger tube poling target seeker comprises guide head, expansion sleeve, taper core bar, is processed with screw thread in the described guide head, and the taper core bar is connected with guide head by screw thread; Described expansion sleeve is enclosed within on the taper core bar, and an end of expansion sleeve contacts with guide head, and the other end contacts with the taper core bar.
The mask that described taper core bar contacts with expansion sleeve has certain tapering.
Described expansion sleeve has step.
The outer surface of described expansion sleeve has netted decorative pattern.
Described guide head is provided with an aperture.
The beneficial effects of the utility model are: the utility model self-locking performance is good, is difficult for breaking away from heat exchanger tube, obtains good effect.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, processed an aperture on the guide head 1, purpose is the taking-up for the ease of target seeker 1, is processed with screw thread in the guide head 1, and taper core bar 3 is connected with guide head 1 by screw thread; Described expansion sleeve 2 is enclosed within on the taper core bar 3, and an end of expansion sleeve 2 contacts with guide head 1, and the other end contacts with taper core bar 3.The mask that taper core bar 3 contacts with expansion sleeve 2 has certain tapering.Rotary steering head 1 is with the 3 outside expansion sleeve 2 diameters increases of sening as an envoy to of crossing mountains of taper core bar, the design that expansion sleeve 2 has a step is to insert the degree of depth of pipe for fixing target seeker, unclamping guide head 1 during taking-up pushes inward and just can take out easily, in addition, the outer surface of expansion sleeve 2 processes netted decorative pattern, to increase the friction of expansion sleeve 2 and tube wall, prevent that target seeker 1 string from moving, coming off.
Claims (5)
1. a heat exchanger poling target seeker comprises guide head (1), expansion sleeve (2), taper core bar (3), and it is characterized in that: described guide head is processed with screw thread in (1), and taper core bar (3) is connected with guide head (1) by screw thread; Described expansion sleeve (2) is enclosed within on the taper core bar (3), and an end of expansion sleeve (2) contacts with guide head (1), and the other end contacts with taper core bar (3).
2. according to the described heat exchanger poling of claim 1 target seeker, it is characterized in that: described taper core bar (3) has certain tapering with the mask that expansion sleeve (2) contacts.
