[0002] The die-casting machine template lock shaft steel sleeve is set in the lock shaft hole on the die-casting machine template, and is used to connect the die-casting machine template with the steel shaft. The lock shaft steel sleeve and the corresponding hole on the template are mostly interference fit, and are generally installed by the temperature difference method, that is, the lock shaft steel sleeve is pre-cooled first, and then the lock shaft steel sleeve is inserted into the relevant hole in a very short time. From taking the lock shaft steel sleeve out of the cooling device to pushing the lock shaft steel sleeve into the hole, the whole process should not exceed 1 minute. In addition, in order to achieve lubrication between the steel shaft, the lock shaft steel sleeve, and the lock shaft hole on the template, corresponding oil holes are provided on the lock shaft steel sleeve and the template. When installing the lock shaft steel sleeve, high precision is required to ensure that the lock shaft steel sleeve and the corresponding oil holes of the lock shaft hole are aligned to ensure the smooth entry of lubricating oil.

[0003] In the field of small and medium-sized die-casting machines, due to the light weight and small size of the shaft-locking steel sleeves, they can be carried and installed by manpower using simple tools. However, for the shaft-locking steel sleeves of super-large die-casting machines, their size and weight are both large (weight exceeds 60kg), and simple operations cannot be carried out by manpower. In addition, due to the small size of the template, the space left for the installation of the shaft-locking steel sleeves is relatively small, making it difficult to use large equipment to lift and install the shaft-locking steel sleeves.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As attached Figure 1 As shown, the present invention relates to a super-large die-casting machine template lock shaft steel sleeve installation device comprising a steel sleeve tray 1, a steel sleeve push plate 2, and a push cylinder 3.

[0024] The steel-cased pallet 1 is a special-shaped metal structure. Its working surface 11 is an arc-shaped cross-section. The diameter of the arc is the same as the diameter of the locking hole K in the template, and the central angle of the arc is less than or equal to 180 degrees. The locking steel sleeve G can be placed on the pallet working surface 11.

[0025] When in use, the steel sleeve pallet 1 has its working surface 11 concentrically aligned with the template locking shaft hole K, and one end of the pallet working surface 11 is in close contact with the side of the locking shaft hole on the template. The locking shaft steel sleeve G is hoisted onto the steel sleeve pallet 1 with a sling. After placement, the cylinder 3 is pushed to move, driving the steel sleeve push plate 2 to move, thereby pushing the locking shaft steel sleeve G into the template locking shaft hole K, so that the installation of the locking shaft steel sleeve G can be completed easily.

[0026] To secure and position the steel-cased pallet 1, a fixing flange 12 is provided on the side of the steel-cased pallet 1 near the locking shaft hole K. Several through-holes are provided on the fixing flange 12, and bolts are used to secure and position the steel-cased pallet 1 to the template. During the tightening of the bolt structure, the working surface 11 of the steel-cased pallet 1 can be easily aligned concentrically with the locking shaft hole K of the template. The template is provided with threaded holes for securing other components, so there is no need to drill new holes in the template when securing the fixing flange 12.

[0027] The pushing cylinder 3 is any one of an electric cylinder, a hydraulic cylinder, and a pneumatic cylinder. The end of the piston rod of the pushing cylinder 3 is connected to the steel sleeve push plate 2. Driven by the pushing cylinder 3, the steel sleeve push plate 2 can reciprocate.

[0028] In order to improve the flexibility of the equipment and avoid the problems caused by the rigid connection between the piston rod of the push cylinder 3 and the steel sleeve push plate 2, a floating connection joint 31 is set between the end of the piston rod of the push cylinder 3 and the steel sleeve push plate 2. The floating connection joint 31 can float at a certain angle, and the steel sleeve push plate 2 is provided with a threaded hole connected to the floating connection joint 31.

[0029] The pushing cylinder 3 is fixed on the pushing cylinder fixing seat 4 , and the pushing cylinder fixing seat 4 is fixed to the end portion of one side of the steel sleeve tray 1 .

[0030] The steel sleeve push plate 2 is a circular plate with a diameter between the inner diameter and outer diameter of the shaft-locking steel sleeve G. To ensure a good fixation between the steel sleeve push plate 2 and the shaft-locking steel sleeve G, a push plate protrusion 21 is provided on the side of the steel sleeve push plate 2 close to the shaft-locking hole K. The outer diameter of the push plate protrusion 21 is equal to the inner diameter of the shaft-locking steel sleeve G. When in use, the push plate protrusion 21 can enter the through hole of the shaft-locking steel sleeve G.

[0031] A push plate raised ring 22 is provided on the upper edge of one side of the steel sleeve push plate 2 near the lock shaft hole K. The inner diameter of the push plate raised ring 22 is equal to the outer diameter of the lock shaft steel sleeve G. When in use, the push plate raised ring 22 can clamp the outer edge of the lock shaft steel sleeve G. Since the steel sleeve push plate 2 needs to push the lock shaft steel sleeve G to move on the steel sleeve tray 1, in order to avoid interference between the push plate raised ring 22 and the steel sleeve tray 1, the push plate raised ring 22 is only provided on the upper part of the steel sleeve push plate 2, and the corresponding central angle is greater than or equal to 180 degrees, and the sum of the central angles corresponding to the arc-shaped cross-section of the tray working surface of the steel sleeve tray is less than 360 degrees.

[0032] During the installation process, the shaft-locking steel sleeve G needs to be lifted. In order to prevent the lifting tool from interfering with the steel sleeve push plate 2 when placing the shaft-locking steel sleeve G on the steel sleeve pallet 1, a notch 23 is provided on the steel sleeve push plate 2. The notch 23 is provided above the steel sleeve push plate 2.

[0033] On the template of an ultra-large die-casting machine, it is generally necessary to set up multiple locking shaft holes K for fixing a shaft. The multiple locking shaft holes K are arranged coaxially front and back, and the front and back distance is generally not large. In order to realize the installation of the locking shaft steel sleeve G in the inner locking shaft hole K2, the installation device also includes a second tray 13 and a piston extension rod 32.

[0034] The second tray 13 is disposed between the two locking shaft holes K, and the cross-sectional shape of the working surface thereof, ie, the upper surface of the second tray 13 , is consistent with that of the tray working surface 11 .

[0035] The second tray 13 and the steel sleeve tray 1 are connected by a connecting steel plate 14 , and the connecting steel plate 14 can pass through the top or side of the locking shaft hole K.

[0036] There is a gap between the end of the second tray 13 close to the side of the inner lock shaft hole K2 and the side of the lock shaft hole K, and the width of the gap is less than half the width of the lock shaft steel sleeve G.

[0037] Since the gap width is less than half the width of the shaft locking steel sleeve G, the shaft locking steel sleeve G will not fall when transferred from the second tray 13 to the inner shaft locking hole K2, and the shaft locking steel sleeve G can smoothly enter the inner shaft locking hole K2.

[0038] The setting of the gap can effectively prevent the second pallet 13 from causing damage to the template when the steel sleeve pallet 1 is installed. At the same time, it has a certain flexibility and can cope with a variety of products with different distances between the two lock shaft holes K.

[0039] In order to ensure that the second pallet 13 is aligned with the inner lock shaft hole K2 and to improve the rigidity of the second pallet 13, a downward protrusion 13a is provided on the side close to the steel sleeve pallet 1, and a threaded hole 13a1 is provided on the protrusion 13. A positioning bolt 13a2 is screwed into the threaded hole 13a1. By tightening the positioning bolt 13a2, the position of the second pallet 13 can be adjusted, and further support is provided for the second pallet 13.

[0040] The piston extension rod 32 is arranged between the floating connection joint 31 and the steel sleeve push plate 2 to extend the range of action of the push cylinder 3. When in use, the piston extension rod 32 is extended through the outer lock shaft hole K and fixed to the steel sleeve push plate 2. Then the lock shaft steel sleeve G is hoisted to the second pallet 13 with a sling. After placement is completed, the push cylinder 3 is activated, and the steel sleeve push plate 2 is driven to move by the piston extension rod 32, thereby pushing the lock shaft steel sleeve G into the inner lock shaft hole K2, so that the installation of the lock shaft steel sleeve G can be completed easily.
