Description

Technical Field

[0001] The invention relates to the technical field of casting molding tool installation, in particular to a sand core transfer auxiliary device. Background Art

[0002] In the casting field, for castings with large volumes and large cavities inside, sand cores are usually used to assist in molding, which can reduce production costs while ensuring the size requirements of the products. The weight of the above-mentioned sand cores is usually heavy. If they are transported only by manpower, it is not only difficult to operate and inefficient, but also easy to damage the sand core, thus affecting the production accuracy of the casting. For this reason, the sand core is usually set to a hollow structure to reduce the weight of the sand core. However, the overall weight of the improved sand core is still heavy, and it needs to rely on corresponding transfer devices for transportation.

[0003] In the prior art, the sand core transfer device usually includes a lifting assembly and a clamping assembly, wherein the clamping assembly usually adopts a pair of clamping components, which clamp the sand core from the left and right sides in the horizontal direction. The clamping components are in contact with the side walls of the sand core, the contact surface is relatively small, and the sand core is unevenly stressed, which can easily lead to stress concentration and damage to the sand core. In addition, the sand core lacks fixation in the axial direction. For sand cores with large axial dimensions or axial segmentation, there is a risk of separation and tipping of the upper and lower ends. If uniform clamping force is to be applied to the horizontal direction (radial) and the vertical direction (axial) at the same time, multiple sets of drive mechanisms need to be set up, resulting in a complex device structure and difficult control operation.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is described below with reference to the accompanying drawings.

[0028] See also Figure 1 and Figure 2 The sand core transport auxiliary device of this embodiment includes an upper guide assembly, a lifting drive member 6, a vertical pressing member 7, a horizontal drive assembly, a horizontal clamping assembly and a lower limit assembly; The upper guide assembly comprises an upper cover plate 1 and a lower cover plate 3 which are arranged in parallel with each other at an interval, the upper cover plate 1 is provided with a lifting lug 10, and a horizontal guide channel is formed between the upper cover plate 1 and the lower cover plate 3; The lifting drive member 6 is arranged at the lower part of the lower cover plate 3, and the output end of the lifting drive member 6 is connected to the vertical pressing member 7. The lower side of the vertical pressing member 7 is formed with a fitting surface that fits with the top of the object to be clamped; The horizontal drive assembly includes two cantilevers 5 arranged opposite to each other, the upper ends of the two cantilevers 5 are limited by a horizontal guide channel and slide in cooperation in the horizontal direction; an inclined wall 51 is provided in the middle of each cantilever 5, and the two inclined walls 51 are symmetrically arranged and correspondingly cooperate with the two ends of the vertical pressing member 7 to form a wedge-shaped mechanism; the lower ends of the two cantilevers 5 are each connected to a horizontal clamping member 12; The lower limit assembly includes a vertical positioning portion and a sliding guide portion; The vertical positioning portion is used to position with the bottom end surface of the object to be clamped to prevent it from rotating in the circumferential direction; The sliding guide portion is used to slide with the horizontal clamping member 12 in the horizontal direction. The two horizontal clamping members 12 are arranged opposite to each other and form a clamping surface 19 matching the contour of the object to be clamped on the adjacent side. The two clamping surfaces 19 are used to wrap and fit the outer wall of the object to be clamped so that the object to be clamped is evenly stressed.

[0029] When the present embodiment is working, after the object to be clamped is placed on the vertical positioning part, the lifting drive member 6 drives the vertical clamping member 7 to move in the vertical direction. Through the action of the wedge-shaped mechanism formed by the vertical clamping member 7 and the inclined wall 51 of the cantilever 5, the vertical movement of the vertical clamping member 7 is converted into the movement of the two cantilevers 5 in the horizontal direction, so that the two cantilevers 5 move toward each other, thereby driving the two horizontal clamping members 12 to move toward each other, and clamping the object to be clamped in the horizontal direction. At the same time, the contact surface of the vertical clamping member 7 contacts the top of the object to be clamped, and the object to be clamped is pressed against the vertical positioning part in the vertical direction. At this time, the working condition is in a clamping state as shown in FIG. Figure 1 Then, the upper cover plate 1 is provided with a lifting lug 10, which is connected to the lifting device to realize the transfer. After being transferred to the work station, the output end of the lifting drive member 6 drives the vertical pressing member 7 to move in the opposite direction, and the two horizontal clamping members 12 move away from each other to release the object to be clamped. At this time, the working condition is released as shown in FIG. Figure 2 shown.

[0030] It can be understood that the two horizontal clamping members 12 are at the same height to form a platform that can move relative to each other, thereby ensuring the horizontality of the object to be clamped during the transportation process.

[0031] In this embodiment, only one power source, the lifting drive 6, is used to realize vertical compression and horizontal clamping, thereby ensuring that the object to be clamped remains stable during transportation, and the clamping force and clamping speed can be adjusted by the lifting drive 6.

[0032] The object to be clamped in this embodiment may be a sand core 23, a casting or other products.

[0033] The sand core 23 of this embodiment is as follows Figure 1As shown, it is a hollow cylinder / cylindrical shape. Accordingly, the clamping surface 19 of the horizontal clamping member 12 is an inner concave arc surface that matches the curvature of the outer wall of the cylinder / cylindrical shape to ensure that it fits with the circumferential outer wall of the sand core 23 during clamping, so that the sand core 23 is evenly stressed and damage caused by increased local pressure and uneven stress due to too small a stress area and uneven stress area is prevented.

[0034] Since this embodiment can meet the requirements of synchronous clamping in the vertical and horizontal directions, it is not only applicable to integrated structures, but also to split structures, especially vertically split structures or objects to be clamped with larger vertical dimensions. For example, for a split-structure sand core comprising an upper and lower unit body, when transporting, the upper and lower unit bodies are first bonded, then placed in the vertical positioning part, and then synchronously clamped in the vertical and horizontal directions, which can effectively avoid tipping due to excessive vertical dimensions or falling apart due to unreliable bonding.

[0035] The upper guide assembly can provide guidance for the movement of the two cantilevers 5, and the sliding guide portion of the lower limit assembly can provide guidance for the movement of the two horizontal clamping members 12, thereby ensuring the stability of the clamping movement process.

Conversely, when the vertical pressing member 7 moves upward, the first inclined surface 701 of the vertical pressing member 7 cooperates with the inner side surface of the inclined wall 51 to form a wedge-shaped mechanism, thereby pushing the cantilever 5 to move inward, so that the two cantilevers 5 move toward each other for clamping.
