Improve as one, the upper end of described screw rod is provided with the contact hole with described screw coaxial, the diameter of shown contact hole is greater than the diameter of described pump shaft, the degree of depth of described contact hole is less than the length that described pump shaft is positioned at the outside of described water pump body, and the bottom surface of described contact hole is described screw rod contact surface.
Improve as one, described screw rod contact surface is the upper surface of described screw rod.
Improve as one, the top of described holding nut is provided with coaxially with described holding nut dodges hole, described in dodge hole diameter be greater than the bearing diameter of described pump shaft, and be less than the end face diameter of described water pump body.
Improve as one, the outer peripheral face of described holding nut is fixedly connected with dwang.
Owing to have employed technique scheme, the beneficial effects of the utility model are: because frock comprises base, screw rod and holding nut, the lower end of screw rod is fixedly connected with base, the upper end of screw rod is threaded with holding nut, the upper end of screw rod is provided with the horizontally disposed screw rod contact surface for contacting with the end face of pump shaft, and the upper surface of holding nut is the nut contact surface contacted with the end face of water pump body, when using this frock to assemble water seal, distance between adjustment screw rod contact surface and nut contact surface, this distance is less than length that pump shaft is positioned at the outside of water pump body, water pump body is placed in frock, the end face of pump shaft contacts with screw rod contact surface, rotational support nut, until nut contact surface contacts with the end face of water pump body, now, because screw rod contact surface contacts with the end face of pump shaft, simultaneously, nut contact surface contacts with the end face of water pump body, when thus press-fiting water seal, relative movement can not be produced between pump shaft and water pump body, ensure the assembly precision of water seal and the product quality of water pump.

Detailed description of the invention
Below by embodiment and accompanying drawing, the utility model is described in further detail.
First embodiment
As shown in Figure 1, a kind of adjustable frock of installing for water pump seal, comprises base 1, screw rod 2 and holding nut 3.The lower end of screw rod 2 is connected with base 1 interference, the upper end of screw rod 2 is provided with screw thread, be threaded with holding nut 3, as shown in Figure 3, the upper end of screw rod 2 offers the contact hole 21 coaxial with screw rod 2, and the bottom surface of contact hole 21 is screw rod contact surface 211, for contacting with the end face of pump shaft 4, the diameter of contact hole 21 is greater than the diameter of pump shaft 4, and the degree of depth of contact hole 21 is less than the length that pump shaft 4 is positioned at the outside of water pump body 7; The upper surface of holding nut 3 is nut contact surface 31, for contacting with the end face of water pump body 7.
As shown in Figure 2, the upper end of holding nut 3 offers coaxially with holding nut 3 dodges hole 311, and the diameter of dodging hole 311 is greater than the diameter of bearing 5, and be less than the end face diameter of water pump body 7, during for preventing from press-fiting water seal 6, nut contact surface 31 touches bearing 5, causes bearing 5 to move.
On the outer peripheral face of holding nut 3, be laid with four screwed holes 32, screwed hole 32 has been threaded dwang 8.
As shown in Figure 4, when using the adjustable frock assembling water seal 6 for water pump seal installation of the present utility model, operation dwang 8 rotational support nut 3, distance between adjustment screw rod contact surface 211 and nut contact surface 31, this distance is less than length that pump shaft 4 is positioned at the outside of water pump body 7, water pump body 7 is placed in this frock, contact hole 21 put into by pump shaft 4, the end face of pump shaft 4 contacts with screw rod contact surface 211, rotational support nut 3, until nut contact surface 31 contacts with the end face of water pump body 7, now, because the screw rod contact surface 211 of the upper end of screw rod 2 contacts with the end face of pump shaft 4, simultaneously, the nut contact surface 31 of the upper end of holding nut 3 contacts with the end face of water pump body 7, thus when press-fiting water seal 6, relative movement can not be produced between pump shaft 4 and water pump body 7, ensure the assembly precision of water seal 6 and the product quality of water pump.
Second embodiment
Second embodiment is substantially identical with the first embodiment, and its difference is, contact hole 21 is not offered in the upper end of screw rod 2, and screw rod contact surface 211 is the upper surface of screw rod 2.Second embodiment is compared with the first embodiment, and because the second embodiment need not in the upper end perforate of screw rod 2, thus structure is more simple, and cost is cheaper.
In sum, adjustable frock for water pump seal installation of the present utility model can adjust the height of frock, the end face of water pump body 7 is contacted with frock with the end face of pump shaft 4 simultaneously, when press-fiting water seal 6, water pump body 7 and pump shaft 4 have identical mobile trend, can not relative movement be produced between water pump body 7 and pump shaft 4, ensure the product quality of the precision that water seal 6 is assembled and water pump.
