[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Figure 1 This is a schematic diagram of the workpiece clamping structure provided in the prior art, such as... Figure 1 As shown, in the existing technology, the guide (for clamping the workpiece) has a bevel or arc on each side. When machining the last two arc surfaces, all four clamped surfaces are bevels, making it impossible to directly clamp with a vise. Due to the small width of the grooves on both sides, the clamping plate is also difficult to clamp. This causes clamping difficulties and affects machining efficiency.

[0022] To address the above problems, this utility model provides a clamping fixture for irregular workpieces. Figure 2 This is a top view schematic diagram of the irregular workpiece clamping fixture provided in an embodiment of this utility model, as shown below. Figure 2 As shown, the tooling includes: a flat-jaw vise 1 and clamping blocks; the two clamping plates 101 of the flat-jaw vise 1 are respectively connected to the opposite sides of a first clamping block 3 and a second clamping block 4. The first clamping block 3 is adapted to clamp one side of the workpiece 2, and the second clamping block 4 is adapted to clamp the other side of the workpiece 2. The first clamping block 3 and the second clamping block 4 are detachably connected to the corresponding clamping plates 101.

[0023] like Figure 2 As shown, each of the two clamping plates 101 of the tooling vise 1 is fixed with a clamping block, namely a first clamping block 3 and a second clamping block 4. The first clamping block 3 and the second clamping block 4 are detachably connected to the corresponding clamping plates 101. Both the first clamping plate 101 and the second clamping plate 101 are adapted to the corresponding sides of the workpiece 2. During clamping, the workpiece can be stably clamped by the first clamping plate 101 and the second clamping plate 101.

[0024] The first clamping block 3 and the second clamping block 4 can be designed with different models according to the different workpieces 2 to ensure that most workpieces can be clamped quickly and stably, thus improving versatility.

[0025] As an optional implementation, the first clamping block 3 is provided with a first boss, which can be inserted into the side groove of the clamping workpiece 2; the second clamping block 4 is provided with a second boss, which can be inserted into the other side groove of the clamping workpiece 2.

[0026] like Figure 3 As shown, the first clamping block 3 has a first boss, and the second clamping block 4 has a second boss. The first boss is fitted into a groove on one side of the workpiece 2, and the other boss is fitted into a groove on the other side of the workpiece 2. During installation, the two sides of the workpiece 2 are clamped by the first clamping block 3 and the second clamping block 4 respectively, and held by the clamping plate 101 of the flat-jaw pliers 1.

[0027] As an optional implementation, both the first clamping block 3 and the second clamping block 4 are provided with locking posts; each clamping plate 101 of the flat-jaw pliers 1 is provided with a locking groove adapted to the locking post.

[0028] To avoid misalignment between the first clamping block 3 and the second clamping block 4 when clamping the workpiece, this embodiment provides locking pins on the first clamping block 3 and the second clamping block 4 to mate with the corresponding locking slots on the clamping plate 101, thereby fixing the relative position of the clamping block and the clamping plate 101.

[0029] As an optional implementation, each clamping plate 101 of the flat-nose pliers 1 is provided with a magnet; the first clamping block 3 and the second clamping block 4 are both made of metal.

[0030] The flat-nose pliers 1 has multiple evenly distributed magnets on each clamping plate 101, and the first clamping block 3 and the second clamping block 4 are both made of metal, so they can be attracted to each clamping plate 101.

[0031] As an optional implementation, both the clamping surfaces of the first clamping block 3 and the second clamping block 4 are provided with abrasion-resistant pads made of soft material.

[0032] To prevent the clamping blocks from causing wear to the clamped workpiece 2, in this embodiment, a layer of anti-wear sheet is provided on the clamping surfaces of the first clamping block 3 and the second clamping block 4. The anti-wear sheet is made of a soft material, such as rubber.

[0033] As an optional implementation, the side wall of the flat-jaw vise 1 is provided with a positioning component 5 for positioning and clamping the workpiece 2.

[0034] To improve the positioning stability of the workpiece 2, this embodiment provides a positioning component 5 on the side wall of the flat-jaw vise 1 to clamp the workpiece 2 from one side. The positioning component 5 works with the clamping plate 101 of the flat-jaw vise 1 to clamp the workpiece, thereby improving the reliability of clamping.

[0035] As an optional implementation, the positioning assembly 5 includes a positioning plate 501, a positioning rod 503, and a fixing member 502; the positioning plate 501 is fixed to the side of the flat-jaw vise 1 by the fixing member 502; the end of the positioning rod 503 passes through the positioning plate 501 and abuts against the end face of the clamped workpiece 2, and the length of the positioning rod 503 passing through the positioning plate 501 is adjustable.

[0036] like Figure 4 As shown, the positioning assembly 5 includes a positioning plate 501, a positioning rod 503, and a fixing member 502. The positioning plate 501 is vertically arranged and connected to the side of the flat-jaw vise 1 through the fixing member 502. The end of the positioning rod 503 passes through the positioning plate 501 and abuts against the end face of the workpiece 2. To adapt to each clamping, the positioning rod 503 can be adjusted on the positioning plate 501, thereby adjusting the length passing through the positioning plate 501.

[0037] As an alternative implementation, the fastener 502 is a bolt; the positioning rod 503 is provided with external threads, which can mate with the internal threads on the positioning plate 501.

[0038] The above technical solution has the following beneficial effects: by setting a clamping block that matches the workpiece and making a positioning device on the side of the vise, the workpiece is positioned close together each time. Using this clamping method, the clamping problem of this workpiece is solved, the clamping efficiency is improved, the quality risks of the workpiece are eliminated, and the product quality is improved.
